A CHEMICAL CONFIRMATION OF THE FAINT BOÖTES II DWARF SPHEROIDAL GALAXY [PDF]
, 2014 We present a chemical abundance study of the brightest confirmed member star of the ultra-faint dwarf galaxy Boötes II from Keck/HIRES high-resolution spectroscopy at moderate signal-to-noise ratios.

THE HOT DARK MATTER MODEL: FURTHER INVESTIGATION
Odessa Astronomical Publications, 2020 e outer region with the dominant hot dark matter (the parabolic orbit of the test particle). It was assumed that the hot dark matter consists of hypothetical Planck neutrinos arising in the decay of the protons at the Planck scale.

THE METAL-POOR KNEE IN THE FORNAX DWARF SPHEROIDAL GALAXY [PDF]
, 2014 We present α-element abundances of Mg, Si, and Ti for a large sample of field stars in two outer fields of the Fornax dwarf spheroidal (dSph) galaxy, obtained with Very Large Telescope/GIRAFFE (R ∼ 16, 000).

Dark Matter Gamma-ray searches in Galaxy Clusters: Status and prospects [PDF]
EPJ Web of ConferencesGalaxy clusters are the largest structures in the Universe, being dark matter (DM) dominated objects. For DM decay, they yield the highest expected fluxes with respect to other prime targets.

Molecular Gas Properties in Young Stellar Clusters with a Suppressed Star Cluster Wind
The Astrophysical Journal Letters, 2023 In compact and dense star-forming clouds a global star cluster wind could be suppressed. In this case stellar feedback is unable to expel the leftover gas from the cluster. Young massive stars remain embedded in a dense residual gas and stir it by moving

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.

HUBBLE SPACE TELESCOPE ABSOLUTE PROPER MOTIONS OF NGC 6681 (M70) AND THE SAGITTARIUS DWARF SPHEROIDAL GALAXY [PDF]
, 2013 We have measured absolute proper motions for the three populations intercepted in the direction of the Galactic globular cluster NGC 6681: the cluster itself, the Sagittarius dwarf spheroidal galaxy, and the field.
