Testing Emergent Gravity in Dwarf Spheroidal Galaxies using Improved Stellar Distributions [PDF]
, 2022 Dwarf spheroidal galaxies (dSphs) are the smallest, least massive galaxies known. Their extreme dynamical mass to light ratios in excess of 100 M/L [189] make them particularly sensitive to theories of dark matter, dark energy, and modified gravity.

The chemical evolution of the dwarf spheroidal galaxy Sextans [PDF]
Astronomy & Astrophysics, 2020 We present our analysis of the FLAMES dataset targeting the central 25′ region of the Sextans dwarf spheroidal galaxy (dSph). This dataset is the third major part of the high-resolution spectroscopic section of the ESO large program 171.B-0588(A) obtained by the Dwarf galaxy Abundances and Radial-velocities Team.

Impact of Cosmic‐Ray Physics on Dark Matter Indirect Searches
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of physics beyond the Standard Model at astronomical scales) provides a unique opportunity and a tough challenge to the high energy astrophysics community.

A SPECTROSCOPIC BINARY IN THE HERCULES DWARF SPHEROIDAL GALAXY [PDF]
The Astrophysical Journal, 2013 We present the radial velocity curve of a single-lined spectroscopic binary in the faint Hercules dwarf spheroidal (dSph) galaxy, based on 34 individual spectra covering more than two years of observations. This is the first time that orbital elements could be derived for a binary in a dSph.

D Simulations of the ISM pollution by SNII and SNI in dwarf spheroidal galaxies [PDF]
, 2005 We present preliminary results of 3-D hydro simulations of the interstellar medium evolution in dwarf spheroidal galaxies undergoing star formation for the first time.

Faint (and bright) variable stars in the satellites of the Milky Way
EPJ Web of Conferences, 2017 I describe two ongoing projects related with variable stars in the satellites of the MilkyWay. In the first project, we are searching for dwarf Cepheid stars (a.k.a δ Scuti and/or SX Phe) in some of the classical dwarf spheroidal galaxies. Our goal is to
