Environmental dependence in the halo model informed by the FLAMINGO simulations
G. Martín Girardi, D. Rana, H. Hoekstra +2
Galaxy-galaxy lensing (GGL) measurements around galaxy samples in different environments provide valuable information about the galaxy-halo connection. In such studies the halo mod…
Weighing Galaxies Inside-Out: Small-Scale Lensing and the Stellar Mass Problem
Divya Rana, Henk Hoekstra, Konrad Kuijken +2
Small-scale galaxy-galaxy weak lensing provides an independent way to probe the stellar initial mass function by constraining the matter distribution within galaxies. We forecast t…
Influence of the large-scale structure velocity field on halo mass assembly within cosmic filaments
Dannaé Díaz-Axtle, Petra Awad, Divya Rana +1
The cosmic web governs the growth of dark matter halos through anisotropic matter flows, yet the role of local velocity-field dynamics in halo mass assembly remains poorly understo…
Assembly Bias in eRASS1 X-ray Galaxy Clusters: Accounting for Non-uniform Survey Exposure
Jitendra Joshi, Divya Rana, Surhud More
Halo assembly bias describes the dependence of halo clustering on properties beyond halo mass and provides a means of connecting halo assembly history to the large-scale matter dis…
