Journal ArticleDOI

Michelle L. M. Collins,Michelle L. M. Collins,Nicolas F. Martin,R. M. Rich,Rodrigo A. Ibata,Scott C. Chapman,Alan W. McConnachie,Annette M. N. Ferguson,Mike Irwin,Geraint F. Lewis +9 more
TL;DR: In this paper, the authors present new, robust kinematic observations for two on-plane M31 dwarf spheroidal galaxies (And XVI and XVII) and compile and compare all available observational metrics for the on- and off-plane dwarfs to search for a signal that would corroborate such a hypothesis.
Journal ArticleDOI
The statistics of microlensing light curves — II. Temporal analysis
Geraint F. Lewis,Mike Irwin +1 more
TL;DR: In this paper, the amplification probability distributions for a large sample of microlensing light curves were presented and a temporal analysis for this light-curve sample was explored using the first-order structure function.
Journal ArticleDOI
The stellar content of the isolated transition dwarf galaxy DDO210
TL;DR: In this paper, the authors used the Subaru Suprime-Cam and VLT FORS1 photometry of the dwarf galaxy DDO210 to study the global stellar content and structural properties of a transition-type galaxy.

HIRES Spectroscopy of APM 08279+5255: Metal Abundances in the Lyα Forest*
TL;DR: In this article, the abundance of carbon in Ly? forest clouds was investigated using high-S/N echelle spectra of the recently discovered ultraluminous QSO APM 08279+5255 and the results showed that approximately 50% of Ly? clouds with hydrogen column densities of log N (H I)? 14.5 have associated weak C IV absorption, with log N(C IV) 12.4? 10-3.
