Laser Interferometer Lunar Antenna: a Sub-Hertz GW Detector on the Moon

Speaker

Volker Quetschke, University of Texas Rio Grande Valley

Abstract

The moon offers unique opportunities and challenges to realize interferometric gravitational wave detectors that are sensitive over a range of frequencies that are currently not covered. Compared with Earth-based detectors, the moon’s reduced gravity and lower seismic activity allow us to shift the sensitivity to lower frequencies.

An update on the Laser Interferometer Lunar Antenna (LILA) project—a next generation gravitational-wave detector on the surface of the Moon—will be presented. The LILA detector will have unique access to sub-Hertz frequencies of gravitational waves. This frequency range of waves cannot be measured by any ongoing or upcoming experiment on the Earth or in space, thus fundamentally changing the landscape of multi-messenger astrophysics that otherwise cannot be achieved. LILA will provide early warnings prior to mergers of black holes and neutron stars. Measurements in the deci-Hertz regime can vastly improve measurements of the Hubble constant, the equation of state of neutron stars, and tests of General Relativity. Furthermore, LILA will uniquely observe phenomena like white dwarf mergers as Type Ia supernovae progenitors, tidal disruption around intermediate mass black holes, and novel dark matter probes.

A preliminary design for the LILA project and the planned future development stages will be shown: the LILA Autonomous Interferometry Technology Demonstration (LILA-AITD), the Initial LILA (iLILA) strainmeter and the full, operational LILA Observatory.

Why and Where Do We Want to Put Telescopes on the Moon?

Speaker

Nivedita Mahesh, CU Boulder

Abstract

The Moon is emerging as a uniquely valuable platform for astrophysics, enabling observations that neither Earth nor free-flying spacecraft can support. This talk surveys the scientific motivation across four complementary regimes. At low radio frequencies, the radio-quiet lunar farside opens a window onto the cosmological Dark Ages and the magnetospheres of exoplanets. In the mid-band gravitational-wave regime, the Moon’s low seismic activity bridges the sensitivity gap between terrestrial and space-based detectors. At ultraviolet wavelengths, its natural vacuum and long coherence times allow high-resolution stellar imaging beyond what is possible on Earth. And in the far-infrared, the cold, stable conditions of permanently shadowed regions offer a naturally cryogenic, absorption-free site for probing star and planet formation and the obscured Universe.

For each regime, I will share updates from the mission concept leads on the efforts now developing within the Astrophysics from the Moon, Mars & Beyond (AMMB) Science Interest Group. Together, these cases point to a paradigm shift: astrophysics from the Moon is becoming not just desirable but necessary.

Constraints on Dynamical Dark Energy from the Full Dark Energy Survey

Speaker

Sujeong Lee, Ohio University

Abstract

The nature of dark energy remains one of the central open questions in cosmology, and recent analyses have reported a weak but intriguing preference for an evolving equation of state. I will present constraints on the w0-wa parameterization from the full six-year Dark Energy Survey (DES) dataset, combining growth and geometric probes — supernovae, BAO, and weak lensing and galaxy clustering (3x2pt) — within a single survey. The DES-only combination yields the tightest such constraints using multiple probes from any single survey, and adding external CMB and DESI BAO data gives a 3.0-sigma deviation from a cosmological constant, with the best-fit always favoring w0 > -1, wa < 0. Because DES relies on different probes and systematics than DESI, this provides an independent cross-check on the recent hints for dynamical dark energy. I will discuss how to interpret these results, and what they imply for Stage IV surveys. This work realizes the multi-probe dark energy program envisioned at the inception of DES.

Cosmic Origins Science in the New Landscape of Space Astrophysics

https://science.nasa.gov/astrophysics/programs/cosmic-origins/community/dgce-sig-seminar-25-june-2026

Speaker

Swara Ravindranath | Deputy Chief Scientist of NASA’s Cosmic Origins Program (NASA GSFC)

Abstract

Cosmic Origins Science covers a broad range of topics that are fundamental to our understanding of the evolution of structure in the Universe and the physical processes that can explain the formation of galaxies, stars, and planets that we observe today. The various space telescopes that operate across the electromagnetic spectrum have been crucial to address some of the most fundamental questions related to our cosmic origins. The landscape of Space Astronomy is evolving fast with innovative technology, industry partnerships, and new commercial launch capabilities. In this talk, I will review the Cosmic Origins Program and discuss the new opportunities that offer strategic pathways for focused-science missions.

The most recent decadal survey in Astronomy and Astrophysics (released in late 2021) identified the most compelling science goals, presented a program of ground- and space-based activities for future investment, and recommended critical actions to support the foundations of the profession as well as the technologies and tools needed to carry out the science. At the request of NASA, NSF, and DOE, this midterm assessment reviews progress towards the priorities from the decadal survey.

The National Academies of Sciences, Engineering, and Medicine (the National Academies) shall convene an ad hoc committee to review the responses of NASA’s Astrophysics program, NSF’s Astronomy program, and DOE’s Cosmic Frontiers program (hereafter the Agencies’ programs) to previous National Academies advice, primarily the 2020 National Academies decadal survey, “Pathways to Discovery in Astronomy and Astrophysics for the 2020s” (Astro2020). 

The committee’s review will include the following tasks:

• Scientific and Technical Landscape: Identify and evaluate the most significant scientific discoveries, technological advancements that could impact implementation, changes to the facilities landscape, and relevant programmatic changes in astronomy and astrophysics since the publication of Astro2020.

• Alignment with Decadal Priorities: Assess the extent to which the programs of the relevant agencies align with the strategies, goals, and priorities outlined in Astro2020 and other pertinent National Academies reports in the context of the Agencies’ current strategic priorities and budgets thus far allotted to them.

• Recommendations for Maximizing Scientific Return: Considering 1 – the advice provided since the publication of Astro2020 by any Federal Advisory Committees active at the time, 2 – the Agencies’ strategic plans, and 3 – the mid-decade contingencies described in the decadal survey, recommend actions that maximize the scientific return of the Agencies’ programs.

• Foundational and Enabling Activities: Evaluate progress and alignment with recommendations on foundational activities, including workforce development, technology maturation, and data infrastructure.

Consideration of International Partnerships and Cross-Agency Opportunities: Assess opportunities to advance the implementation of priorities outlined in Astro2020 that are presented by changes in international partnerships and cross-agency cooperative capabilities.

The review should not revisit or alter the scientific priorities or mission recommendations provided in the decadal survey and related National Academies reports but may assess progress in implementation of the recommended science and activities portfolio and on other potential activities in preparation for the next decadal survey.

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.
