We apply a new galaxy group-finder to the Main Galaxy Sample of the SDSS. This algorithm
introduces new freedom to assign halos to galaxies that is self-calibrated by comparing the …

The growth and properties of galaxies are thought to be closely connected to the ones of
their host dark matter haloes. Despite the importance of this so-called galaxy–halo …

We use the DR9 of the DESI legacy imaging survey and SDSS galaxy groups to measure
the conditional luminosity function (CLF) for groups with halo mass M h≥ 10 12 M⊙ and …

In this investigation, we leverage the combination of the Dark Energy Spectroscopic
Instrument (DESI) Legacy Imaging Surveys Data Release 9, Survey Validation 3, and Year 1 …

We quantify evolution in the cluster-scale stellar mass–halo mass (SMHM) relation's
parameters using 2323 clusters and brightest central galaxies (BCGs) over the redshift …

Using photometrically selected galaxies from the Hyper Suprime-Cam (HSC) survey, we
measure the stellar-mass density profiles for satellite galaxies around isolated central …

Understanding the physical connection between cluster galaxies and massive haloes is key
to mitigating systematic uncertainties in next-generation cluster cosmology. We develop a …

The standard paradigm for the formation of the Universe suggests that large structures are
formed from hierarchical clustering by the continuous accretion of less massive galaxy …

We present HaloFlow, a new machine-learning approach for inferring the mass of host dark
matter halos, M h, from the photometry and morphology of galaxies (https://github …

Cluster cosmology depends critically on how optical clusters are selected from imaging
surveys. We compare the conditional luminosity function (CLF) and weak-lensing (WL) halo …
