The average stellar population age and metallicity of intermediate-redshift quiescent galaxies
Ivana Damjanov, Margaret J. Geller, Jubee Sohn
The HectoMAP spectroscopic survey provides a unique mass-limited sample of more than 35,000 quiescent galaxies () covering the redshift range . We segregate…
Cosmology with voids
Benjamin C. Bromley, Margaret J. Geller
Voids are dominant features of the cosmic web. We revisit the cosmological information content of voids and connect void properties with the parameters of the background universe.…
The Velocity Dispersion Function for Quiescent Galaxies in Massive Clusters from IllustrisTNG
Jubee Sohn, Margaret J. Geller, Josh Borrow +1
We derive the central stellar velocity dispersion function for quiescent galaxies in 280 massive clusters with in IllustrisTNG300. The velocity di…
Velocity Dispersions of Quiescent Galaxies in IllustirisTNG
Jubee Sohn, Margaret J. Geller, Josh Borrow +1
We examine the central stellar velocity dispersion of subhalos based on IllustrisTNG cosmological hydrodynamic simulations. The central velocity dispersion is a fundamental observa…
The splashback radius and the radial velocity profile of galaxy clusters in IllustrisTNG
Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +1
We use 1697 clusters of galaxies from the Illustris TNG300-1 simulation (mass M and redshift range ) to explore the physics of the c…
Galaxy cluster mass accretion rates from IllustrisTNG
Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +2
We use simulated cluster member galaxies from Illustris TNG300-1 to develop a technique for measuring the galaxy cluster mass accretion rate (MAR) that can be applied directly to o…
