Journal ArticleDOI
The observed properties of dwarf galaxies in and around the local group
TL;DR: In this paper, the authors present a survey of the structural and dynamical properties of all dwarf galaxies in and around the Local Group, and various aspects of our observational understanding of this volume-limited sample are discussed.
Journal ArticleDOI
The remnants of galaxy formation from a panoramic survey of the region around M31

TL;DR: A panorama of galaxy structure of the Andromeda galaxy (M31) is reported, which directly confirms the basic tenets of the hierarchical galaxy formation model and reveals the shared history of M31 and M33 in the unceasing build-up of galaxies.
Journal ArticleDOI
A vast, thin plane of corotating dwarf galaxies orbiting the Andromeda galaxy

TL;DR: Radial velocity measurements reveal that the satellites in this structure have the same sense of rotation about their host, and shows conclusively that substantial numbers of dwarf satellite galaxies share the same dynamical orbital properties and direction of angular momentum.
Journal ArticleDOI

TL;DR: The Next Generation Virgo Cluster Survey (NGVS) as discussed by the authors uses the 1 deg2 MegaCam instrument on the Canada-France-Hawaii Telescope to carry out a comprehensive optical imaging survey of the Virgo cluster, from its core to its virial radius.
Journal ArticleDOI
The Tidal Evolution of Local Group Dwarf Spheroidals
TL;DR: In this article, the authors use N-body simulations to study the evolution of dwarf spheroidal galaxies driven by galactic tides, and they adopt a cosmologically motivated model where dSphs are approximated by a King model embedded within an NFW halo.
