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
Stellar chemical signatures and hierarchical galaxy formation

TL;DR: In this paper, the authors compared the chemistries of stars in the Milky Way dwarf spheroidal (dSph) satellite galaxies with stars from the Galaxy, and found that the [α/Fe] ratios of most stars in dSph galaxies are generally lower than similar metallicity Galactic stars in this extended sample.
Journal ArticleDOI

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.

TL;DR: In this article, the authors reported the discovery and monitoring of the near-infrared counterpart (AT2017gfo) of a binary neutron-star merger event detected as a gravitational wave source by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo (GW170817) and as a short gamma-ray burst by Fermi Gamma-ray Burst Monitor (GBM) and Integral SPI-ACS (GRB 170817A).
