Modeling a Conversation Between a Black Hole and Its Galaxy
A new modeling technique lets black holes and their surroundings “talk” more easily, allowing researchers to simulate the complicated physics of accretion and feedback.
The 80s Called, They Want Their Ultra-Long-Period Radio Transient Back
Astrobites reports on two objects whose unusually spaced-out radio pulses have puzzled astronomers. Could these objects be white dwarfs or magnetars?
Featured Image: Mapping Matter in the Universe
Researchers measure tiny distortions in the oldest light in the universe to determine where matter is concentrated.
How to Slice a Star
Massive stars are not typically inclined to go gentle into the good night. Some, new work suggests, might dramatically cut themselves in two using a “relativistic blade.”
Monthly Roundup: Betelgeuse, Betelgeuse, Betelgeuse
Three recent studies of the famous red supergiant examine the aftermath of the Great Dimming, probe the possibility of a stellar merger, and reconsider some critical evidence that suggests that Betelgeuse was once two stars.
A First Glimpse of Changing-Look Active Galactic Nuclei with SDSS-V
Astrobites reports on the changing-look active galactic nuclei seen in the first year of the fifth Sloan Digital Sky Survey.
K2-18b May Not Be Habitable After All
A new interpretation of JWST spectra suggests that exoplanet K2-18b is a gas-rich world without a habitable surface rather than an ocean world.
Do Dwarf Galaxy Collisions Start or Stop Star Formation? Yes.
While collisions between dwarf galaxies usually result in bursts of star formation, new research suggests that galaxy interactions can also make star formation shut off.
When Stars, Disks, and Black Holes Meet, Outbursts Follow
New research explores how a star colliding with a disk of gas around a supermassive black hole might give rise to the quasi-periodic eruptions seen in certain galaxies.
Sednoids: Echoes of a Rogue Planet in the Early Solar System?
Astrobites reports on the possibility that an ancient rogue planet is responsible for the unusual orbits of a trio of solar system objects called sednoids.
Featured Image: Minidisks in Massive Binaries
Researchers investigate the behavior of minidisks: the small disks of gas that collect around the individual supermassive black holes in a binary pair.
