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 ...

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 ...

Stellar Density Profiles of Dwarf Spheroidal Galaxies [PDF]
Astrophysical Journal, 2019 We apply a flexible parametric model, a combination of generalized Plummer profiles, to infer the shapes of the stellar density profiles of the Milky Way’s satellite dwarf spheroidal galaxies (dSphs).

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.

Constraints on dark matter annihilation in dwarf spheroidal galaxies from low frequency radio observations [PDF]
Physical Review D, 2019 We present the first observational limits on the predicted synchrotron signals from particle Dark Matter annihilation models in dwarf spheroidal galaxies at radio frequencies below 1 GHz.

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,

Discovery prospects of dwarf spheroidal galaxies for indirect dark matter searches [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We study the prospects for the Large Synoptic Survey Telescope (LSST) to find new dwarf spheroidal galaxies in the Milky Way. Adopting models of Milky-Way halo substructure and phenomenological prescriptions connecting subhalos and satellite galaxies, we

Globular clusters and dwarf spheroidal galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract Traditionally, globular clusters and dwarf spheroidal galaxies have been distinguished by using one or more of the following criteria: (i) mass, (ii) luminosity, (iii) size, (iv) mass-to-light ratio and (v) spread in metallicity.
