Structural evolution of quiescent galaxies at intermediate redshifts at UV and red rest-frame wavelengths

Michele Pizzardo, Ivana Damjanov, Jubee Sohn +1

We model the wavelength dependence of structural parameters for a mass-limited sample () of quiescent galaxies with using $griz…

Cluster Lensing Mass Inversion (CLUMI+): Combining Dynamics and Weak Lensing around Galaxy Clusters

Keiichi Umetsu, Michele Pizzardo, Antonaldo Diaferio +1

We present CLUMI+, a self-consistent, multiprobe methodology for reconstructing the mass distribution in and around galaxy clusters by combining gravitational lensing and dynamical…

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…

An IllustrisTNG View of the Caustic Technique for Galaxy Cluster Mass Estimation

Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +2

The TNG300-1 run of the IllustrisTNG simulations includes 1697 clusters of galaxies with M covering the redshift range . We build mock spectros…

Mass accretion rates of the HectoMAP clusters of galaxies

M. Pizzardo, J. Sohn, M. J. Geller +2

We estimate the mass accretion rate (MAR) of the 346 clusters of galaxies in the HectoMAP Cluster Survey. The clusters span the redshift range and the mass ra…
