Pieces of the puzzle: ancient substructure in the Galactic disc
Amina Helmi,Julio F. Navarro,Birgitta Nordström,Birgitta Nordström,Johan Holmberg,Mario G. Abadi,Matthias Steinmetz +6 more
TL;DR: In this paper, the authors search for signatures of past accretion events in the Milky Way in the recently published catalogue by Nordstrom et al., containing accurate spatial and kinematic information as well as metallicities for 13 240 nearby stars.
Journal ArticleDOI

TL;DR: The Pristine survey as mentioned in this paper is a narrow-band photometric survey focused on the metallicity-sensitive Ca HK lines and conducted in the Northern hemisphere with the wide-field imager MegaCam on the Canada-France-Hawaii Telescope.
Journal ArticleDOI
Tidal Torques and the Orientation of Nearby Disk Galaxies
TL;DR: In this article, the authors use numerical simulations to investigate the orientation of the angular momentum axis of disk galaxies relative to their surrounding large-scale structure, and they find that this is closely related to the spatial configuration at turnaround of the material destined to form the galaxy.
Journal ArticleDOI
The Core Density of Dark Matter Halos: A Critical Challenge to the ΛCDM Paradigm?
TL;DR: In this paper, the authors compare the central mass concentration of cold dark matter (CDM) halos found in cosmological N-body simulations with constraints derived from the Milky Way disk dynamics and from the Tully-Fisher relation.
Journal ArticleDOI
The chosen few: the low-mass haloes that host faint galaxies
Till Sawala,Carlos S. Frenk,Azadeh Fattahi,Julio F. Navarro,Tom Theuns,Richard G. Bower,Robert A. Crain,Robert A. Crain,Michelle Furlong,Adrian Jenkins,Matthieu Schaller,Joop Schaye +11 more
TL;DR: The authors used hydrodynamic cosmological simulations of the Local Group to study the discriminating factors for galaxy formation in the early Universe and connect them to the present-day properties of galaxies and halos.
