SHAPE: cosmology with cluster halo intrinsic alignments from subhalo distributions
Shogo Ishikawa, Atsushi Taruya, Takahiro Nishimichi +2
Galaxy clusters trace the most massive dark matter haloes, whose shapes and orientations reflect the imprint of the cosmic large-scale tidal field. This paper introduces the Subhal…

A new constraint on galaxy-halo connections of [O II] emitters via HOD modelling with angular clustering and luminosity functions from the Subaru HSC survey
Shogo Ishikawa, Teppei Okumura, Masao Hayashi +1
Establishing a robust connection model between emission-line galaxies (ELGs) and their host dark haloes is of paramount importance in anticipation of upcoming redshift surveys. We…

Galaxy-dark matter connection from weak lensing in imaging surveys: Impact of photometric redshift errors
Navin Chaurasiya, Surhud More, Daichi Kashino +2
The uncertainties in photometric redshifts and stellar masses from imaging surveys affect galaxy sample selection, their abundance measurements, as well as the measured weak lensin…
