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(-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-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.

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.

Galaxy Disks and Disk Galaxies1 [PDF]

Publications of the Astronomical Society of the Pacific, 2000
The conference Galaxy Disks and Disk Galaxies, sponsored by the Vatican Observatory, was held in June 12-16, 2000 at the Pontifical Gregorian University, in Rome (Italy). The meeting hosted about 230 participants coming from 30 countries. The very full program consisted of 29 review papers, 34 invited talks, and more than 180 posters.

The edge of the Galaxy [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We use cosmological simulations of isolated Milky Way (MW)-mass galaxies, as well as Local Group (LG) analogues, to define the ‘edge’ – a caustic manifested in a drop in density or radial velocity – of Galactic-sized haloes, both in dark matter and in stars.
