An Analytical Galactic Chemical Evolution Model with Gas Inflow and a Terminal Wind

The Astrophysical Journal
We present a new analytical galactic chemical evolution (GCE) model with gas inflow, internally caused outflow, and extra gas loss after a period of time. The latter mimics the ram pressure stripping of a dwarf satellite galaxy near the pericenter of its

Extracting limits on dark matter annihilation from gamma ray observations towards dwarf spheroidal galaxies [PDF]

, 2012
Dwarf spheroidal galaxies compose one of the most dark matter dominated classes of objects, making them a set of targets to search for signals of dark matter annihilation.

Kinematically Cold Populations at Large Radii in the Draco and Ursa Minor Dwarf Spheroidal Galaxies [PDF]

, 2004
We present projected velocity dispersion profiles for the Draco and Ursa Minor (UMi) dwarf spheroidal galaxies based on 207 and 162 discrete stellar velocities, respectively.

Legacy Analysis of Milky Way Dwarf Spheroidal Satellite Galaxies: An Update

The Astrophysical Journal Letters
Studies of Fermi Large Area Telescope (LAT) data coincident with dwarf spheroidal satellite galaxies (dSphs) of the Milky Way have put the most stringent constraints on models of annihilating dark matter (DM) with candidate masses in the GeV–TeV range ...

Relieving Tensions Related to the Dark Matter Interpretation of the Fermi-LAT Data

Galaxies, 2018
Recently, many studies indicate that the GeV gamma ray excess signal from the central Milky Way can be best explained by ∼40–50 GeV dark matter annihilating via the b b ¯ channel.
