Constraining the Stellar-to-Halo Mass Relation with Galaxy Clustering and Weak Lensing from DES Year 3 Data

The Open Journal of Astrophysics
We develop a framework to study the relation between the stellar mass of a galaxy and the total mass of its host dark matter halo using galaxy clustering and galaxy-galaxy lensing measurements. We model a wide range of scales, roughly from $\sim 100 \; {\

Cold Gas Infall onto a Brightest Group Galaxy via a Gas-rich Minor Merger

The Astrophysical Journal Letters
Dust and cold gas are not uncommon in nearby early-type galaxies (ETGs) and represent an important aspect of their evolution. However, their origin has been debated for decades.

ON THE FORMATION OF THE DISK OF SATELLITES OF THE MILKY WAY: SIMULATION OF THE COLLISION OF TWO GALAXIES

Momento, 2014
At present there is some evidence showing that the satellite galaxies of the Milky Way might be distributed on a disc structure, known as the disc of satellites.

Ursa Major III/UNIONS 1: The Darkest Galaxy Ever Discovered?

The Astrophysical Journal
The recently discovered stellar system Ursa Major III/UNIONS 1 (UMa3/U1) is the faintest known Milky Way satellite to date. With a stellar mass of ${16}_{-5}^{+6}\,{M}_{\odot }$ and a half-light radius of 3 ± 1 pc, it is either the darkest galaxy ever ...

Machine Learning the Dark Matter Halo Mass of Milky Way-Like Systems

The Open Journal of Astrophysics
Despite the Milky Way's proximity to us, our knowledge of its dark matter halo is fairly limited, and there is still considerable uncertainty in its halo mass.
