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…

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…
