Shocks in the Stacked Sunyaev-Zel'dovich Profiles of Clusters II: Measurements from SPT-SZ + Planck Compton-y Map
D. Anbajagane, C. Chang, B. Jain +43
We search for the signature of cosmological shocks in stacked gas pressure profiles of galaxy clusters using data from the South Pole Telescope (SPT). Specifically, we stack the la…
Galaxy Velocity Bias in Cosmological Simulations: Towards Percent-level Calibration
Dhayaa Anbajagane, Han Aung, August E. Evrard +8
Galaxy cluster masses, rich with cosmological information, can be estimated from internal dark matter (DM) velocity dispersions, which in turn can be observationally inferred from…
Baryonic Imprints on DM Halos: Population Statistics from Dwarf Galaxies to Galaxy Clusters
Dhayaa Anbajagane, August E. Evrard, Arya Farahi
In a purely cold dark matter universe, the initial matter power spectrum and its subsequent gravitational growth contain no special mass- or time-scales, and so neither do the emer…
A Test of the Standard Cosmological Model with Geometry and Growth
Uendert Andrade, Dhayaa Anbajagane, Rodrigo von Marttens +2
We perform a general test of the and cosmological models by comparing constraints on the geometry of the expansion history to those on the growth of stru…
