No Evidence of a Dichotomy in the Elliptical Galaxy Population

open access: yesThe Astrophysical Journal
The advent of large integral field spectroscopic surveys has found that elliptical galaxies (EGs) can be divided into two classes: the fast rotators (whose kinematics are dominated by rotation) and the slow rotators (which exhibit slow or no rotation ...

Where Have All the Little Red Dots Gone? Supermassive Black Hole Binary Dynamics and Its Impact on Galaxy Properties

open access: yesThe Astrophysical Journal Letters
Recent James Webb Space Telescope observations have revealed a peculiar class of galaxies at redshifts z  ≳ 6, characterized by extremely high central stellar densities and overmassive central supermassive black holes (SMBHs), “little red dots” (LRDs). A

Core Formation by Binary Scouring and Gravitational Wave Recoil in Massive Elliptical Galaxies

open access: yesThe Astrophysical Journal
Scouring by supermassive black hole (SMBH) binaries is the most accepted mechanism for the formation of the cores seen in giant elliptical galaxies. However, an additional mechanism is required to explain the largest observed cores.
