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…
Hyper Suprime-Cam Y3 results: photo- bias calibration with lensing shear ratios and cosmological constraints from cosmic shear
Divya Rana, Surhud More, Hironao Miyatake +3
We present an independent calibration of the photometric redshift (photo-) distributions for source galaxies in the HSC-Y3 weak lensing survey using small-scale galaxy-galaxy le…
Splashback radius and the mass accretion rate of RASS MCMF galaxy clusters
Jitendra Joshi, Divya Rana, Surhud More +1
We present measurements of the radial profile of mass and galaxy number density around X-ray selected ROSAT All Sky Survey-Multi-Component Matched Filter galaxy clusters using Year…
Stellar mass dependence of galaxy size-dark matter halo radius relation probed by Subaru-HSC survey weak lensing measurements
Preetish K. Mishra, Divya Rana, Surhud More
We investigate the stellar mass-dependence of the galaxy size-dark matter halo radius relation for low redshift galaxies using weak gravitational lensing measurements. Our sample c…
The eROSITA Final Equatorial-Depth Survey (eFEDS) -- Splashback radius of X-ray galaxy clusters using galaxies from HSC survey
Divya Rana, Surhud More, Hironao Miyatake +6
We present the splashback radius measurements around the SRG/eROSITA eFEDS X-ray selected galaxy clusters by cross-correlating them with HSC S19A photometric galaxies. The X-ray se…
Subaru HSC weak lensing of SDSS redMaPPer cluster satellite galaxies: Empirical upper limit on orphan fractions
Amit Kumar, Surhud More, Divya Rana
Weak gravitational lensing directly probes the matter distribution surrounding satellite galaxies in galaxy clusters. We measure the weak lensing signal induced on the shapes of ba…
The Subaru HSC weak lensing mass-observable scaling relations of spectroscopic galaxy groups from the GAMA survey
Divya Rana, Surhud More, Hironao Miyatake +5
We utilize the galaxy shape catalogue from the first-year data release of the Subaru Hyper Suprime-cam Survey (HSC) to study the dark matter content of galaxy groups in the Univers…
Incompleteness Matters Not: Inference of from BBH-galaxy cross-correlations
Sayantani Bera, Divya Rana, Surhud More +1
We show how the angular clustering between gravitational-wave standard sirens and galaxies with known redshifts allows an inference of the Hubble constant, regardless of whether th…
