Luminosity-Dependent Assembly Bias of Central Galaxies from Weak Lensing and Clustering

Zhenjie Liu, Hironao Miyatake, Joop Schaye +3

Assembly bias, which is the variation in halo clustering at fixed mass driven by formation history, has long been predicted by numerical simulations but remains difficult to confir…

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…

Cosmological feedback from a halo assembly perspective

Luisa Lucie-Smith, Hiranya V. Peiris, Andrew Pontzen +6

The impact of feedback from galaxy formation on cosmological probes is typically quantified in terms of the suppression of the matter power spectrum in hydrodynamical compared to g…

The eROSITA view of the Abell 3391/95 field: Cluster Outskirts and Filaments

Angie Veronica, Thomas H. Reiprich, Florian Pacaud +17

Aims. We aim to characterize the gas properties in the cluster outskirts () and in the detected inter-cluster filaments () of the A3391/95 system and t…

A New Galaxy Cluster Merger Capable of Probing Dark Matter: Abell 56

David Wittman, Rodrigo Stancioli, Kyle Finner +3

We report the discovery of a binary galaxy cluster merger via a search of the redMaPPer optical cluster catalog, with a projected separation of 535 kpc between the BCGs. Archival X…
