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 ( $M_{⋆} > 1 0^{10} M_{⊙}$ ) of $\sim 27, 000$ quiescent galaxies with $0.2 < z < 0.6$ 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 $M_{200 c} > 1 0^{14}$ M $_{⊙}$ and redshift range $0.01 \leq z \leq 1.04$ ) to explore the physics of the c…
