Journal ArticleDOI

Alan W. McConnachie,Mike Irwin,Rodrigo A. Ibata,John Dubinski,Lawrence M. Widrow,Nicolas F. Martin,Patrick Côté,Aaron Dotter,Julio F. Navarro,Annette M. N. Ferguson,Thomas H. Puzia,Geraint F. Lewis,Arif Babul,Pauline Barmby,Olivier Bienaymé,Scott Chapman,Robert Cockcroft,Michelle L. M. Collins,Mark A. Fardal,William E. Harris,Avon Huxor,A. Dougal Mackey,Jorge Peñarrubia,R. Michael Rich,Harvey B. Richer,Arnaud Siebert,Nial R. Tanvir,David Valls-Gabaud,K. A. Venn +28 more
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
The Canadian Cluster Comparison Project: detailed study of systematics and updated weak lensing masses
Henk Hoekstra,Ricardo Herbonnet,Adam Muzzin,Arif Babul,Andi Mahdavi,Massimo Viola,Marcello Cacciato +6 more
TL;DR: In this article, the authors revisited the analysis of a sample of 50 clusters studied as part of the Canadian Cluster Comparison Project and found that the uncertainty in the determination of photometric redshifts is the largest source of systematic error for our mass estimates.
Journal ArticleDOI
On dwarf elliptical galaxies and the faint blue counts
Arif Babul,Martin J. Rees +1 more
TL;DR: In this article, the starburst epoch is determined by the decline in the UV background, which results in the stably confined photoionized gas in dark halos of M ∼ 10 9 M ⊙ being able to cool and settle in the centre of the haloes and undergo star formation.
Journal ArticleDOI
The role of black holes in galaxy formation and evolution
A. Cattaneo,S. M. Faber,James Binney,Avishai Dekel,John Kormendy,Richard Mushotzky,Arif Babul,Philip Best,Marcus Brüggen,Andrew C. Fabian,Carlos S. Frenk,A. Khalatyan,Hagai Netzer,Andisheh Mahdavi,Joseph Silk,Matthias Steinmetz,Lutz Wisotzki +16 more
TL;DR: A central question in galaxy evolution is the degree to which this process has caused the decline of star formation in large elliptical galaxies, which typically have little cold gas and few young stars, unlike spiral galaxies.
Journal ArticleDOI
The nature and space density of fossil groups of galaxies
TL;DR: In this article, the properties of a sample of galaxy groups with very unusual distributions of galaxy luminosities were described, and a small X-ray-selected, flux-limited sample of fossil groups with well-known selection criteria was constructed.
