Physicists Devise New Way to Listen for β€˜Hairy’ Black Holes

When two black holes merge, the resulting object rings like a struck bell, radiating gravitational waves that fade in a distinctive pattern called ringdown.

Our Milky Way Galaxy Likely Underwent Disk Flip after Ancient Galactic Collision: Study

Using supercomputer simulations of galaxies like the Milky Way, Batrakov et al. found that galaxies with slowly rotating stellar haloes are more likely to have experienced a major β€˜disk flip,’ where our Galaxy’s disk changed its orientation by more than 90 degrees. Image credit: Batrakov et al.

A head-on collision with another galaxy billions of years ago may have dramatically reoriented the Milky Way’s disk, according to new supercomputer simulations that reveal how violent mergers can leave spiral galaxies looking surprisingly normal today.

FCC took pricey gifts from Paramount as the company needed approval for deals

The rich and famous who filed into the Kennedy Center’s opera house in December were there to enjoy one of the nation’s most exclusive celebrations of the performing arts: the center’s annual honors gala.

The black-tie event, hosted by President Donald Trump, prioritized tickets to people who donated more than $75,000 to the center. This year, it feted Hollywood icon Sylvester Stallone, the legendary glam rock band Kiss and the Grammy Award-winning disco pioneer Gloria Gaynor.

Among the attendees that evening were two lower-profile government officials whose regulatory decisions had been crucial to the future of the gala’s broadcast sponsor, CBS, and its parent company, Paramount.
