Galaxy Halo Masses from Galaxy-Galaxy Lensing [PDF]
The Astrophysical Journal, 2000 We present measurements of the extended dark halo profiles of bright early type galaxies at redshifts 0.1 to 0.9 obtained via galaxy-galaxy lensing analysis of images taken at the CFHT using the UH8K CCD mosaic camera.

Galaxy-galaxy(-galaxy) lensing as a sensitive probe of galaxy evolution [PDF]
Astronomy & Astrophysics, 2012 The gravitational lensing effect provides various ways to study the mass environment of galaxies. We investigate how galaxy-galaxy(-galaxy) lensing can be used to test models of galaxy formation and evolution.

Stress testing ΛCDM with high-redshift galaxy candidates [PDF]
Nature Astronomy, 2022 Early James Webb Space Telescope (JWST) results suggest a high level of star formation in the first 500 million years of the Universe. A study of the available mass from dark matter haloes shows that unexpectedly high-mass JWST galaxy candidates may ...

An inventory of galaxies in cosmic filaments feeding galaxy clusters: galaxy groups, backsplash galaxies, and pristine galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Galaxy clusters grow by accreting galaxies from the field and along filaments of the cosmic web. As galaxies are accreted they are affected by their local environment before they enter (pre-processing), and traverse the cluster potential.

THE ORIENTATION OF GALAXIES IN GALAXY CLUSTERS [PDF]
The Astrophysical Journal, 2010 We present an analysis of the spatial orientations of galaxies in the 247 optically selected rich Abell clusters, having in the considered area at least 100 members. We investigated the relation between angles giving information about galaxy angular momenta and the number of members in each structure.
