Journal ArticleDOI
Galactic halo stellar structures in the Triangulum-Andromeda region
TL;DR: The main sequence and main-sequence turnoff of the Triangulum-Andromeda structure were recovered by Majewski and colleagues at a heliocentric distance of ~20 kpc as discussed by the authors.
Journal ArticleDOI

TL;DR: In this paper, the authors present abundances for seven stars in the (extremely low-metallicity) tail of the Sculptor dwarf spheroidal galaxy, from spectra taken with X-shooter on the ESO VLT.
Journal ArticleDOI
Determining the Location of the Tip of the Red Giant Branch in Old Stellar Populations: M33, Andromeda I & II
Alan W. McConnachie,Mike Irwin,A. M. N. Ferguson,Rodrigo A. Ibata,Geraint F. Lewis,Nial Tanvir +5 more
TL;DR: In this paper, a least-squares fit of a data-adaptive slope to the luminosity function in 1 magnitude windows is used to identify the tip of the red giant branch (TRGB) in nearby metal poor stellar systems.

TL;DR: The IPHAS dataset as discussed by the authors contains a photometric catalogue of about 200 million unique objects, coupled with associated image data covering about 1600 square degrees in three passbands, covering the early and late stages of stellar evolution from T-Tauri stars to planetary nebulae.
