Consistency tests between SDSS and DESI BAO measurements
Basundhara Ghosh, Carlos Bengaly
In this work, we investigate whether the baryon acoustic oscillation (BAO) measurements from redshift surveys, like the Sloan Digital Sky Survey (SDSS), and the Dark Energy Spectro…

A unified linear intrinsic alignment model for elliptical and disc galaxies and the resulting ellipticity spectra
Basundhara Ghosh, Kai Nussbaumer, Eileen Sophie Giesel +1
Alignments of spiral galaxies were thought to result from tidal torquing, where tidal field of the cosmic large-scale structure exert torquing moments onto dark matter haloes, dete…
