A multi-simulation study of relativistic SZ temperature scalings in galaxy clusters and groups
Elizabeth Lee, Dhayaa Anbajagane, Priyanka Singh +6
The Sunyaev-Zeldovich (SZ) effect is a powerful tool in modern cosmology. With future observations promising ever improving SZ measurements, the relativistic corrections to the SZ…
Cosmology dependency of halo masses and concentrations in hydrodynamic simulations
Antonio Ragagnin, Alexandro Saro, Priyanka Singh +1
We employ a set of Magneticum cosmological hydrodynamic simulations that span over different cosmologies, and extract masses and concentrations of all well-resolved haloes bet…
Constraints on precipitation-limited hot halos from massive galaxies to galaxy clusters
Priyanka Singh, G. M. Voit, Biman B. Nath
We present constraints on a simple analytical model for hot diffuse halo gas, derived from a fit spanning two orders of magnitude in halo mass ($M_{500} \sim 10^{12.5}-10^{14.5} M_…
Cosmology dependence of galaxy cluster scaling relations
Priyanka Singh, Alex Saro, Matteo Costanzi +1
The abundance of galaxy clusters as a function of mass and redshift is a well known powerful cosmological probe, which relies on underlying modelling assumptions on the mass-observ…
X-ray and SZ constraints on the properties of hot CGM
Priyanka Singh, Subhabrata Majumdar, Biman B. Nath +1
We use observations of stacked X-ray luminosity and Sunyaev-Zel'dovich (SZ) signal from a cosmological sample of and massive galaxies, respectively, with $…
Constraining the X-ray AGN halo occupation distribution: implications for eROSITA
Priyanka Singh, Alexandre Refregier, Subhabrata Majumdar +1
The X-ray emission from active galactic nucleus (AGN) is a major component of extragalactic X-ray sky. In this paper, we use the X-ray luminosity function (XLF) and halo occupation…
Suppression of galactic outflows by cosmological infall and circumgalactic medium
Priyanka Singh, Sandeep Rana, Jasjeet S. Bagla +1
We investigate the relative importance of two galactic outflow suppression mechanisms : a) Cosmological infall of the intergalactic gas onto the galaxy, and b) the existence of a h…
Probing the circumgalactic baryons through cross-correlations
Priyanka Singh, Subhabrata Majumdar, Biman B. Nath +2
We study the cross-correlation of distribution of galaxies, the Sunyaev-Zel'dovich (SZ) and X-ray power spectra of galaxies from current and upcoming surveys and show these to be e…
CMB distortion from circumgalactic gas
Priyanka Singh, Biman B. Nath, Subhabrata Majumdar +1
We study the Sunyaev-Zel'dovich (SZ) distortion of the cosmic microwave background radiation (CMBR) from extensive circumgalactic gas (CGM) in massive galactic halos. Recent observ…
