Journal ArticleDOI
Deconstructing dwarf galaxies: a Suprime-Cam survey of Andromeda II
TL;DR: In this paper, a deep, subhorizontal-branch, multicolour photometry of the Andromeda II dSph was presented with the Subaru Suprime-Cam wide-field camera.
Journal ArticleDOI
Deep Gemini/GMOS imaging of an extremely isolated globular cluster in the Local Group

TL;DR: The colour-magnitude diagram for this object extends ∼5 mag below the tip of the red-giant branch and exhibits features consistent with an ancient metal-poor stellar population, including a long, well-populated horizontal branch, which suggests that MGC1 has spent many gigayears in isolation.
Journal ArticleDOI
The Monitor project: JW 380 – a 0.26‐, 0.15‐M⊙, pre‐main‐sequence eclipsing binary in the Orion nebula cluster

TL;DR: In this paper, a pre-main-sequence (PMS) eclipsing binary (EB) with a 5.3 d orbital period was detected as part of a high-cadence time-resolved photometric survey (the Monitor project) using the 2.5m Isaac Newton Telescope and Wide Field Camera for a survey of a single field in the Orion nebula cluster.
Journal ArticleDOI
A bayesian approach to locating the red giant branch tip magnitude. i.
Anthony R. Conn,Anthony R. Conn,Geraint F. Lewis,Rodrigo A. Ibata,Quentin A. Parker,Quentin A. Parker,Daniel B. Zucker,Daniel B. Zucker,Alan W. McConnachie,Nicolas F. Martin,Mike Irwin,Nial R. Tanvir,Mark A. Fardal,Annette M. N. Ferguson +13 more
TL;DR: In this article, the authors presented a new approach for identifying the tip of the red giant branch (TRGB) which, as they show, works robustly even on sparsely populated targets.
Journal ArticleDOI
Deep wide-field imaging down to the oldest main sequence turn-offs in the Sculptor dwarf spheroidal galaxy
T. J. L. de Boer,Eline Tolstoy,A. Saha,Knut Olsen,Mike Irwin,Giuseppina Battaglia,Vanessa Hill,Matthew Shetrone,Giuliana Fiorentino,Andrew A. Cole +9 more
TL;DR: In this article, wide field photometry of resolved stars in the nearby Sculptor dwarf spheroidal galaxy using CTIO/MOSAIC, going down to the oldest main sequence turn-off was presented.
