Dark satellites and the morphology of dwarf galaxies [PDF]
, 2012 One of the strongest predictions of the LambdaCDM cosmological model is the presence of dark satellites orbiting all types of galaxies. We focus here on the dynamical effects of such satellites on disky dwarf galaxies, and demonstrate that these ...

The quest for dark matter in dwarf spheroidal galaxies with the Cherenkov Telescope Array [PDF]
EPJ Web of Conferences, 2019 Dwarf spheroidal galaxies are among the best environments that can be studied with Cherenkov telescopes for indirect searches of γ-ray signals coming from dark matter self-interaction (annihilation or decay), due to their proximity and negligible ...

Young Globular Clusters and Dwarf Spheroidals [PDF]
, 1999 Most of the globular clusters in the main body of the Galactic halo were formed almost simultaneously. However, globular cluster formation in dwarf spheroidal galaxies appears to have extended over a significant fraction of a Hubble time.

Abundance Analysis of Stars at Large Radius in the Sextans Dwarf Spheroidal Galaxy
The Astrophysical Journal, 2023 We present the stellar parameters and chemical abundances of 30 elements for five stars located at large radii (3.5–10.7 times the half-light radius) in the Sextans dwarf spheroidal galaxy. We selected these stars using proper motions, radial velocities,

The Origin Of Dwarf Spheroidal Galaxies [PDF]
Symposium - International Astronomical Union, 1983 Two dwarf spheroidal galaxies are associated with the Magellanic Stream with their major axes oriented along it. Evidence suggests that all the dwarf spheroidal satellites of the Galaxy belong to one or other of two streams of tidal debris. If this is true the orbits will give the first reliable determination of the total mass of the Galaxy out to 120 ...

EPJ Web of Conferences, 2012 While recent sky surveys have uncovered large numbers of ever fainter Milky Way satellites, their classification as star clusters, low-luminosity galaxies, or tidal overdensities remains often unclear. Likewise, their contributions to the build-up of the

Abundance ratios of red giants in low mass ultra faint dwarf spheroidal galaxies [PDF]
, 2015 Low mass dwarf spheroidal galaxies are key objects for our understanding of the chemical evolution of the pristine Universe and the Local Group of galaxies.

Dwarf Spheroidal Satellite Formation in a Reionized Local Group [PDF]
, 2014 Dwarf spheroidal satellite galaxies have emerged a powerful probe of small-scale dark matter clustering and of cosmic reionization. They exhibit structural and chemical continuity with dwarf irregular galaxies in the field and with spheroidal galaxies in
