The Cusp–Core Problem in Gas-Poor Dwarf Spheroidal Galaxies [PDF]
Galaxies, 2021 This review deals with the inconsistency of inner dark matter density profiles in dwarf galaxies, known as the cusp–core problem. In particular, we aim to focus on gas-poor dwarf galaxies.

Tidal Dwarf Galaxies and Missing Baryons [PDF]
Advances in Astronomy, 2010 Tidal dwarf galaxies form during the interaction, collision, or merger of massive spiral galaxies. They can resemble “normal” dwarf galaxies in terms of mass, size, and become dwarf satellites orbiting around their massive progenitor.

Search for Ultraheavy Dark Matter from Observations of Dwarf Spheroidal Galaxies with VERITAS [PDF]
The Astrophysical Journal, 2023 Dark matter is a key piece of the current cosmological scenario, with weakly interacting massive particles (WIMPs) a leading dark matter candidate. WIMPs have not been detected in their conventional parameter space (100 GeV ≲ M _χ ≲ 100 TeV), a mass ...

The mass of dwarf spheroidal galaxies and the missing satellite problem [PDF]
, 2005 We present the results from a suite of N-body simulations of the tidal stripping of two-component dwarf galaxies comprising some stars and dark matter. We show that recent kinematic data from the local group dwarf spheroidal (dSph) galaxies suggests that

New constraints on the mass of fermionic dark matter from dwarf spheroidal galaxies [PDF]
, 2020 Dwarf spheroidal galaxies are excellent systems to probe the nature of fermionic dark matter due to their high observed dark matter phase-space density. In this work, we review, revise and improve upon previous phase-space considerations to obtain lower ...

The Effect of Tidal Stripping on Composite Stellar Populations in Dwarf Spheroidal Galaxies [PDF]
Advances in Astronomy, 2010 We use N-body simulations to study the effects of tides on the kinematical structure of satellite galaxies orbiting a Milky Way-like potential. Here we focus on the evolution of a spherical, dark matter dominated satellite, which is modelled with two ...

THE PAndAS VIEW OF THE ANDROMEDA SATELLITE SYSTEM. II. DETAILED PROPERTIES OF 23 M31 DWARF SPHEROIDAL GALAXIES [PDF]
, 2016 We present a comprehensive analysis of the structural properties and luminosities of the 23 dwarf spheroidal galaxies that fall within the footprint of the Pan-Andromeda Archaeological Survey (PAndAS). These dwarf galaxies represent the large majority of

Jeans analysis for dwarf spheroidal galaxies in wave dark matter [PDF]
, 2017 Although still under debate, observations generally suggest that dwarf spheroidal (dSph) galaxies exhibit large constant-density cores in the centers, which can hardly be explained by dissipationless cold dark matter simulations without baryonic feedback.

CARBON IN RED GIANTS IN GLOBULAR CLUSTERS AND DWARF SPHEROIDAL GALAXIES [PDF]
, 2015 We present carbon abundances of red giants in Milky Way (MW) globular clusters and dwarf spheroidal galaxies (dSphs). Our sample includes measurements of carbon abundances for 154 giants in the clusters NGC 2419, M68, and M15 and 398 giants in the dSphs ...
