Searches for HI in the Outer Parts of Four Dwarf Spheroidal Galaxies
, 1999 Previous searches for atomic gas in our Galaxy's dwarf spheroidal companions have not been complete enough to settle the question of whether or not these galaxies have HI, especially in their outer parts.

Dark Matter Searches with the Fermi-LAT in the Direction of Dwarf Spheroidals [PDF]
arXiv, 2015 The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-dominated objects known. Due to their proximity, high dark matter content, and lack of astrophysical backgrounds, dwarf spheroidal galaxies are widely considered to be among the most promising targets for the indirect detection of dark matter via gamma rays.

Astrophysical site(s) of r-process elements in galactic chemodynamical evolution model
EPJ Web of Conferences, 2016 Astrophysical site(s) of rapid neutron-capture process (r-process) is (are) not identified yet. Although core-collapse supernovae have been regarded as one of the possible candidates of the astrophysical site of r-process, nucleosynthesis studies suggest

The 3.5 keV line from stringy axions
Journal of High Energy Physics, 2017 An interesting result in particle astrophysics is the recent detection of an unexplained 3.5 keV line from galaxy clusters. A promising model, which can explain the morphology of the signal and its non-observation in dwarf spheroidal galaxies, involves a

The Kinematics of Dwarf Spheroidal Galaxies
, 1997 I review observational data on the kinematic properties of dwarf spheroidal galaxies in the halo of the Milky Way and beyond. The present data confirm previous claims that these galaxies have unusually large central velocity dispersions. `Simple' sources of bias such as binary stars, internal atmospheric motions, measurement errors, and small sample ...

Self-interacting Dark Matter Interpretation of Crater II
The Astrophysical Journal LettersThe satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold dark matter.
