Journal ArticleDOI
Why the Canis Major overdensity is not due to the Warp: analysis of its radial profile and velocities
Nicolas F. Martin,Rodrigo A. Ibata,Blair C. Conn,Geraint F. Lewis,Michele Bellazzini,Mike Irwin,A. W. McConnachie +6 more
TL;DR: In this article, the authors show that the Momany et al. (2004) warp model overestimates the number of stars in the Northern hemisphere, hence hiding the Canis Major (CMa) feature in the South.
Journal ArticleDOI
The kinematic footprints of five stellar streams in Andromeda's halo
Scott Chapman,Scott Chapman,Rodrigo A. Ibata,Mike Irwin,Andreas Koch,B. Letarte,Nicolas F. Martin,Michelle L. M. Collins,Geraint F. Lewis,A. W. McConnachie,Jorge Peñarrubia,R. M. Rich,D. Trethewey,Annette M. N. Ferguson,Avon Huxor,Nial R. Tanvir +15 more
TL;DR: The spectroscopic analysis of five stellar streams discovered in the halo of M31 as well as the extended star cluster, EC4, which lies within Stream 'C', concludes that the M31 stellar halo is largely made up of multiple kinematically cold streams.
Journal ArticleDOI
Submillimeter Observations of the Ultraluminous BAL Quasar APM 08279+5255
TL;DR: In this article, the influence of gravitational lensing upon these models is considered and it is shown that while the emission from the central continuum emitting region may be significantly enhanced, lensing induced magnification cannot easily reconcile the models with observations.
Journal ArticleDOI

TL;DR: In this paper, the authors derived a distance of 13 kpc based on light travel time considerations, which is supported by two other distance estimation methods, and identified two possible evolutionary scenarios, in at least one of which the system is massive enough to produce a Type Ia supernova on merging.
Journal ArticleDOI
The ISLAndS project II: The Lifetime Star Formation Histories of Six Andromeda dSphs

TL;DR: In this article, the Initial Star formation and Lifetimes of Andromeda Satellites (ISLAndS) project uses Hubble Space Telescope imaging to study a representative sample of six Andromeda dSph satellite companion galaxies.
