Dear Physics of the Cosmos (PhysCOS) community members-

As we begin planning the next iteration of the NASA Artificial Intelligence and Machine Learning Science and Technology Interest Group (AI/ML STIG) seminar series, we are expanding our leadership council and would love your help. We are writing to invite you to nominate yourself or a colleague to join.

We are especially looking for early-career researchers, including graduate students, postdocs, and early-career scientists, who are broadly interested in the intersection of AI and astronomy. You do not need to be an expert across the whole field; curiosity and a willingness to help the community learn matter most.

The organizational duties are light. Council members help suggest speakers and run the remote seminars, which mainly means sending email reminders and introducing the speaker. It is a great way to meet people across the field and to help shape a series that reaches the NASA community and beyond.

Two themes will anchor next year’s series:

1. Agentic AI for Astrophysics. How LLM agents and multi-agent systems can accelerate astronomical research, from literature and data analysis to simulation and discovery workflows.

2. AI and Astronomy in the US: Initiatives, Funding, and Broader Impacts. The wider landscape of AI in astronomy, including national initiatives, funding opportunities, AI pedagogy, the ethics and philosophy of AI in science, and ways AI can support NASA priorities such as ASTRA.

Please use this Google form to nominate yourself or someone else by the end of this week (20 June 2026). 

Wishing you the best,

Dr Francesca Civano & Dr Brian Humensky
PhysCOS Chief Scientists, NASA GSFC

Central Shocks and Metal-Enriched Outflows: A New View of AGN Feedback

Speaker

Peixin Zhu (Harvard University)

Abstract

The growth of galaxies and their central supermassive black holes (SMBHs) is tightly linked. However, the exact impact of active galactic nuclei (AGNs) feedback on the host galaxy is still uncertain, with different observations suggesting AGNs enhance, suppress, or do not affect the host galaxy star formation rate. Resolving these controversies requires proper treatment of shocks, which are known to exist with AGN-driven outflow and yet are difficult to distinguish from AGN emission. In my talk, I will present a new theoretical three-dimensional diagram built for integral-field spectroscopy that cleanly separates star formation, AGN, and shock-dominated spaxels. Furthermore, these separation results can be combined with theoretical diagnostics to map the spatial distribution of gas-phase metallicity, ionization parameter, and gas pressure within these galaxies. After applying this new technique to 8 nearby Seyfert galaxies, we reveal that AGN and star formation coexist in the galaxy center, and fast shocks are present at the base of AGN outflows in some galaxies. We also find that outflowing gas is systematically metal-enhanced relative to adjacent star-forming rings. I will discuss how these results refine the picture of AGN feedback and the implications for nuclear enrichment and gas transport.

Investigating AGN Feeding and Feedback Through Circumnuclear Gas Kinematics in NGC 3079 and NGC 1068

Speaker

Dr. Ming-Yi Lin (University of Toledo)

Abstract

Studying gas kinematics in the circumnuclear regions (< 100 pc) of nearby AGNs on spatial scales of <10 pc provides insights into gas transport toward the supermassive black hole (SMBH) and the impact of AGN feedback in both radiative and kinetic forms. The kinematics of cold molecular gas are observed with radio interferometers (ALMA and NOEMA), while the warm molecular gas in the near-IR are studied using adaptive optics (AO)-assisted integral field spectrographs (IFS; Keck/OSIRIS). In this talk, I will use NGC 1068 and NGC 3079, two nearby Compton-thick AGNs, as pilot targets to discuss two distinct types of molecular outflows located at distances of ~40 pc from the SMBH: a cooling-efficient, momentum-driven outflow and a cooling-inefficient, energy-driven outflow. I will also present the discrepancy between Bondi accretion prescriptions and observationally constrained mass accretion rates.

Dear Astrophysics Strategic Technology & Research Accelerator (ASTRA) community members-

As we prepare for our Ad ASTRA Community Science workshop, we are writing to share important updates regarding the agenda structure and instructions for abstract submissions. 

The Community Science (Ad ASTRA) Workshop is organized by the NASA Astrophysics Division to engage the community in identifying future large, strategic astrophysics missions. Structured over three thematic days—Science, Capabilities and Implementation, and Community Discussion—the workshop provides a comprehensive framework to connect scientific priorities with technological readiness and mission implementation. Across all three days, plenaries, panels, breakout sessions, and poster contributions are designed to maximize community interactions and discussion. The outcomes of the workshop will help NASA prioritize mission concepts and shape a balanced, forward-looking astrophysics portfolio that is consistent with the Astro2020 recommendations and existing and future science gaps.

To best serve the community and facilitate meaningful collaboration, we are splitting the mission concept presentations into two distinct focuses: Science on Day 1, and Capabilities and Implementation on Day 2. We are relying on you—the concept teams and the broader community—to submit abstracts for both days. We are also offering the option to present mission concepts as posters, and will offer the opportunity to present as posters any abstracts for which there is insufficient room in the parallel sessions.

Please review the detailed agenda structure and submission guidelines below:

Day 1: Science Focus

• Science Questions: Day 1 will focus on open science priorities and questions from strategic documents (Astro 2020 Decadal Survey, Enduring Quests – Daring Visions from 2014) and more recent science questions that the mission concepts submitted to ASTRA will address. 
• Abstract Submission: Presentations for Day 1 are not restricted to mission concept team members. We strongly encourage other scientists in the community to submit abstracts presenting important science questions and to use this opportunity to connect with concept teams.
• Breakout Sessions: These sessions will be organized by science themes (Compact Objects and Energetic Phenomena, Cosmology, Galaxies, Exoplanets & Astrobiology, Stars and Stellar Populations). Moderators will present a summary of the panel discussions at the end of Day 1.

Day 2: Mission Concepts – Capabilities and Implementation

• Focus: Day 2 is focused on implementation, capabilities, and technologies (software and hardware) relevant to the ASTRA submitted mission concepts. A summary of the Innovation for Astrophysics Missions Workshop (May 2026) will inform discussions regarding industry and other capabilities and opportunities that may be leveraged. 
• Breakout Sessions: These sessions will be organized by capability groups, which will be determined once the submitted mission concept documents are reviewed.
• Format & Goals: Breakout sessions will feature a mix of presentations and flexible discussion. The goal is for teams with concepts at varying maturity levels to collaborate, find commonalities, and strengthen their respective capability groups.
• Abstract Submission Note: Teams may submit multiple abstracts for these sessions if their concept spans different capabilities (e.g., requiring both UV and X-ray technologies).

Day 3 & Workshop Outcome

A primary goal of this workshop is to refine a draft “science-to-capabilities” matrix, which will be built using inputs from your submitted ASTRA mission concept documents. During the Day 1 and 2 breakout sessions, moderators will capture key discussion points to present during end-of-day summary panels. On Day 3 of the workshop, we will hold a plenary discussion to recap the week and collaboratively revise the “science-to-capabilities” matrix. Together as a community, we will add, refine, and prioritize science questions, mapping them to mission concepts. 

Key Upcoming Dates:

• 24 June 2026: Abstract submission deadline (link). If you have already submitted an abstract and would like to modify it based on the guidelines above, please delete your previous contribution and send another submission. 
• 26 June 2026: Mission Concept Document submission deadline (template, submission portal)
• 10 July 2026: Contributed abstracts selected for talks and posters 

We look forward to your abstract submissions and to a highly collaborative and productive workshop! 

Best regards,

Dear Physics of the Cosmos (PhysCOS) community members-

As we prepare for our Ad ASTRA Community Science Workshop, we are writing to share important updates regarding the agenda structure and instructions for abstract submissions. 

The Community Science (Ad ASTRA) Workshop is organized by the NASA Astrophysics Division to engage the community in identifying future large, strategic astrophysics missions. Structured over three thematic days—Science, Capabilities and Implementation, and Community Discussion—the workshop provides a comprehensive framework to connect scientific priorities with technological readiness and mission implementation. Across all three days, plenaries, panels, breakout sessions, and poster contributions are designed to maximize community interactions and discussion. The outcomes of the workshop will help NASA prioritize mission concepts and shape a balanced, forward-looking astrophysics portfolio that is consistent with the Astro2020 recommendations and existing and future science gaps.

To best serve the community and facilitate meaningful collaboration, we are splitting the mission concept presentations into two distinct focuses: Science on Day 1, and Capabilities and Implementation on Day 2. We are relying on you—the concept teams and the broader community—to submit abstracts for both days. We are also offering the option to present mission concepts as posters, and will offer the opportunity to present as posters any abstracts for which there is insufficient room in the parallel sessions.

Please review the detailed agenda structure and submission guidelines below:

Day 1: Science Focus

• Science Questions: Day 1 will focus on open science priorities and questions from strategic documents (Astro 2020 Decadal Survey, Enduring Quests – Daring Visions from 2014) and more recent science questions that the mission concepts submitted to ASTRA will address. 
• Abstract Submission: Presentations for Day 1 are not restricted to mission concept team members. We strongly encourage other scientists in the community to submit abstracts presenting important science questions and to use this opportunity to connect with concept teams.
• Breakout Sessions: These sessions will be organized by science themes (Compact Objects and Energetic Phenomena, Cosmology, Galaxies, Exoplanets & Astrobiology, Stars and Stellar Populations). Moderators will present a summary of the panel discussions at the end of Day 1.

Day 2: Mission Concepts – Capabilities and Implementation

• Focus: Day 2 is focused on implementation, capabilities, and technologies (software and hardware) relevant to the ASTRA submitted mission concepts. A summary of the Innovation for Astrophysics Missions Workshop (May 2026) will inform discussions regarding industry and other capabilities and opportunities that may be leveraged. 
• Breakout Sessions: These sessions will be organized by capability groups, which will be determined once the submitted mission concept documents are reviewed.
• Format & Goals: Breakout sessions will feature a mix of presentations and flexible discussion. The goal is for teams with concepts at varying maturity levels to collaborate, find commonalities, and strengthen their respective capability groups.
• Abstract Submission Note: Teams may submit multiple abstracts for these sessions if their concept spans different capabilities (e.g., requiring both UV and X-ray technologies).

Day 3 & Workshop Outcome

A primary goal of this workshop is to refine a draft “science-to-capabilities” matrix, which will be built using inputs from your submitted ASTRA mission concept documents. During the Day 1 and 2 breakout sessions, moderators will capture key discussion points to present during end-of-day summary panels. On Day 3 of the workshop, we will hold a plenary discussion to recap the week and collaboratively revise the “science-to-capabilities” matrix. Together as a community, we will add, refine, and prioritize science questions, mapping them to mission concepts. 

Key Upcoming Dates:

• 24 June 2026: Abstract submission deadline (link). If you have already submitted an abstract and would like to modify it based on the guidelines above, please delete your previous contribution and send another submission. 
• 26 June 2026: Mission Concept Document submission deadline (template, submission portal)
• 10 July 2026: Contributed abstracts selected for talks and posters 

We look forward to your abstract submissions and to a highly collaborative and productive workshop! 

Best regards,

The Ad ASTRA Workshop Organizing Committee

The deci-Hertz Interferometer Space Antenna

Speaker

Jacob Slutsky, NASA / GSFC

Abstract

The origins and fate of massive compact objects such as black holes, neutron stars, and white dwarfs can only be fully answered by measuring deci-Hertz (dHz) gravitational wave emission. A plethora of innovative mission concepts have been proposed motivated by this need, promising incredible potential sensitivity and requiring substantial technical development. Like COBE rather than Plank, we optimize time to first knowledge over ultimate sensitivity. We describe the highest priority science goals contained in and motivating a dHz observatory, the minimum sensitivity required to make these observations, and the fastest, least-costly mission that meets these minimum requirements. We dub this mission the Deci-hertz Interferometer Space Antenna (DISA).
