Journal ArticleDOI
The remnants of galaxy formation from a panoramic survey of the region around M31
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
Binaries in globular-clusters
Piet Hut,Steve McMillan,Jeremy Goodman,Mario Mateo,E. S. Phinney,Carlton Pryor,Harvey B. Richer,Frank Verbunt,Martin D. Weinberg +8 more
TL;DR: The initial spatial, mass, and energy distributions of primordial binary systems are largely unknown as discussed by the authors, and the initial spatial and energy distribution of non-primordial binaries are unknown.
Journal ArticleDOI
A young white dwarf companion to pulsar B1620-26: evidence for early planet formation.
TL;DR: The color and magnitude of the stellar companion indicate that it is an undermassive white dwarf of age 480 × 106 ± 140 × 106 years, which places a constraint on the recent history of this triple system and supports a scenario in which the current configuration arose through a dynamical exchange interaction in the cluster core.
Journal ArticleDOI
The white dwarf cooling sequence of the globular cluster messier 4
Brad M. S. Hansen,Brad M. S. Hansen,James Brewer,Greg Fahlman,Bradley Kenneth Gibson,Rodrigo A. Ibata,Marco Limongi,R. Michael Rich,Harvey B. Richer,Michael M. Shara,Peter B. Stetson +10 more
TL;DR: The white dwarfs of the globular cluster M4 extend to approximately 2.5 mag fainter than the peak of the local Galactic disk white dwarf luminosity function as discussed by the authors.
Journal ArticleDOI

Brad M. S. Hansen,Jay Anderson,James Brewer,Aaron Dotter,Gregory G. Fahlman,Jarrod R. Hurley,Jasonjot S. Kalirai,Ivan R. King,David Reitzel,Harvey B. Richer,R. Michael Rich,Michael M. Shara,Peter B. Stetson +12 more
TL;DR: The results of a deep Hubble Space Telescope (HST) exposure of the nearby globular cluster NGC 6397, focusing on the cluster's white dwarf cooling sequence, are presented in this paper.
