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…

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 $M_{200 c} > 1 0^{14}$ M $_{⊙}$ covering the redshift range $0.01 - 1.04$ . We build mock spectros…
