Journal ArticleDOI
Response of Dark Matter Halos to Condensation of Baryons: Cosmological Simulations and Improved Adiabatic Contraction Model
TL;DR: In this article, the effects of cooling of gas in the inner regions of halos using high-resolution cosmological simulations that include gas dynamics, radiative cooling, and star formation were investigated.
Journal ArticleDOI

TL;DR: In this article, the authors presented five new satellites of the Milky Way discovered in Sloan Digital Sky Survey (SDSS) imaging data, four of which were followed-up with either the Subaru or Isaac Newton Telescopes.
Journal ArticleDOI
The Tumultuous Lives of Galactic Dwarfs and the Missing Satellites Problem
TL;DR: In this paper, the authors analyzed the dynamical evolution of the substructure halos in a high-resolution cosmological simulation of Milky Way-sized halos, in a hierarchical cold dark matter (CDM) cosmology.
Journal ArticleDOI
Destruction of the Galactic Globular Cluster System
TL;DR: In this article, the authors investigate the dynamical evolution of the Galactic globular cluster system in considerably greater detail than has been done hitherto, finding that destruction rates are significantly larger than given by previous estimates.
Journal ArticleDOI
Neutrino emission from neutron stars
TL;DR: In this article, the main neutrino emission mechanisms in neutron star crusts and cores are reviewed, and the results are presented in the form convenient for practical use, including the effects of various neutrinos reactions on the cooling of neutron stars.
