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.

Moderate Galaxy-Galaxy Lensing [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
We study moderate gravitational lensing where a background galaxy is magnified substantially, but not multiply imaged, by an intervening galaxy. We focus on the case where both the lens and source are elliptical galaxies.

Galaxy subgroups in galaxy clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
Galaxies which fall into clusters as part of the same infall halo can retain correlations due to their shared origin. N-body simulations are used to study properties of such galaxy subgroups within clusters, including their richnesses and prevalence. The

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 and galaxy-cluster lensing with the SDSS and FIRST surveys [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We perform a galaxy-galaxy lensing study by correlating the shapes of $\sim$2.7 $\times$ 10$^5$ galaxies selected from the VLA FIRST radio survey with the positions of $\sim$38.5 million SDSS galaxies, $\sim$132000 BCGs and $\sim$78000 SDSS galaxies that

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.
