An aMACEing Set of Radio Galaxy Flares
Astrobites reports on two mysterious flares detected from a radio galaxy by the brand new MACE gamma-ray telescope.
Featured Image: Green Seeds at Cosmic Noon
An exploration of galaxies during our universe’s star-formation heyday reveals a population of bright, compact regions called green seeds.
A Late-Stage Infall Renovation: Mapping the Circumstellar Disk of AB Aurigae
What happens when a young star captures some extra gas and dust? New observations of a dusty disk reveals how a late-stage infall event may be influencing planet formation in AB Aurigae.
Gravitationally Lensed Gravitational Waves from Black Holes Around Black Holes
Gravitational-wave detectors have spotted dozens of merging black hole pairs. New research explores whether any of these collisions could have happened in the disk around an accreting supermassive black hole.
Twenty Thousand Stars Later, They Didn’t Find a Single Planet (and That’s Cool, Too!)
Astrobites reports on a study that shows that hot stars seem to host fewer small planets than their cooler stellar cousins.
Fifteen Years of X-Rays from Andromeda’s Supermassive Black Hole
What has the supermassive black hole at the center of the Milky Way’s galactic neighbor been up to? The Chandra X-ray Observatory provides all the details.
Featured Image: A Ribbon Around the Heliosphere
When mapping energetic atoms from the edge of our solar system, the Interstellar Boundary Explorer discovered an unexpected ribbon-like feature that researchers are still working to understand.
Them’s the (Balmer) Breaks
Astrobites reports on what might be powering the strange, puzzling young galaxies known as little red dots.
Confirmed at Last: Barnard’s Star Hosts Four Tiny Planets
Following decades of disproven claims, four small exoplanets have been confirmed to orbit Barnard’s Star, the second-closest star system to Earth after Alpha Centauri.
Astronomers Measure Turnover in Initial Mass Function for the First Time
When a gas cloud collapses to form a star cluster, how many objects form, and what are their masses? Research published today provides answers about the low-mass end of the star and brown dwarf formation process.
Observational Obstacles to Detecting Early Universe Supermassive Black Holes
Recent JWST observations have stirred up concerns about over-massive black holes in the early universe. A new study allays these concerns while showing that over-massive black holes are just scratching the surface of the full black hole population.
