Dark matter haloes have long been recognized as one of the fundamental building blocks of
large-scale structure formation models. Despite their importance–or perhaps because of it …

Using the weak gravitational lensing data from the Hyper Suprime-Cam Subaru Strategic
Program (HSC survey), we study the potential of different stellar mass estimates in tracing …

The shapes of galaxy N-point correlation functions can be used as standard rulers to
constrain the distance–redshift relationship. The cosmological density fields traced by late …

We investigate the importance of various dynamical features in predicting the dynamical
state (ds) of galaxy clusters, based on the Random Forest (RF) machine-learning approach …

We present C lassification of C luster Ga laxy Me mbers (C 2-GaMe), a classification
algorithm based on a suite of machine learning models that differentiates galaxies into …

Projection effects, whereby galaxies along the line of sight to a galaxy cluster are mistakenly
associated with the cluster halo, present a significant challenge for optical cluster …

We present a per cent-level accurate model of the line-of-sight velocity distribution of
galaxies around dark matter haloes as a function of projected radius and halo mass. The …

Satellite galaxies can be used to indicate the dynamic mass of galaxy groups and clusters.
In this study, we apply the axisymmetric Jeans Anisotropic Multi-Gaussian Expansion (JAM) …

The outskirts of accreting dark matter haloes exhibit a sudden drop in density delimiting their
multistream region. Due to the dynamics of accretion, the location of this physically …

Galaxy imaging surveys represent a promising opportunity for testing cosmological models
but suffer from significant challenges associated with galaxy redshift uncertainty. I present …
