Seeing Red: New Constraints on Origin of JWST’s Little Red Dots
Supercritical accretion of black holes may drive the formation of enigmatic “little red dots.”
DPS 58: Days 1 and 2
News from the 58th meeting of the AAS Division for Planetary Sciences (DPS): discovering a new dwarf planet candidate in our solar system, cracking mysteries about Europa’s ice shell, clarifying our understanding of Titan’s hazy dunes, and much more.
These “Ice Giants” Have a Hot Secret
Astrobites reports on a possible piping-hot secret about the so-called “ice giant” planets in our solar system, Uranus and Neptune.
Supercritical accretion of black holes may drive the formation of enigmatic “little red dots.”
Most galaxies are expected to contain at least one massive black hole, but how robust is this prediction? New research uses simulations to look at which galaxies tend to have more or fewer black holes, and with what properties.
Get to know your neighbors with a new database of nearby star clusters, stellar associations, and substellar objects.
The center of our galaxy is known to host hundreds of radio-emitting filaments, but the energy source for these features remains a mystery. New simulations attempt to shed light on what powers galactic non-thermal filaments.
Not All Black Holes Who Wander Are Lost
Astrobites reports on a new diagnostic tool used to understand how the neighborhood a black hole grows up in may affect the rest of its life.
The white dwarf–brown dwarf pair J0404+1112 — one of only about a dozen known systems like it — offers researchers a chance to study a substellar atmosphere blasted with intense radiation.
