Search for Ultraheavy Dark Matter from Observations of Dwarf Spheroidal Galaxies with VERITAS

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 ...

DELVE-DEEP Survey: The Faint Satellite System of NGC 55

The Astrophysical Journal
We report the first comprehensive census of the satellite dwarf galaxies around NGC 55 (2.1 Mpc) as a part of the DECam Local Volume Exploration DEEP (DELVE-DEEP) survey. NGC 55 is one of four isolated, Magellanic analogs in the Local Volume around which

Simulations of the formation and evolution of isolated dwarf galaxies [PDF]

, 2008
We present new fully self-consistent models of the formation and evolution of isolated dwarf galaxies. We have used the publicly available N-body/SPH code HYDRA, to which we have added a set of star formation criteria, and prescriptions for chemical ...

The Magellanic Group and the Seven Dwarfs [PDF]

, 2008
The Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. This group, dominated by the LMC, contained ~4% of the mass of the Milky Way prior to its accretion and tidal disruption, but ~

Galaxias Enanas del Grupo Local

Momento, 2009
The satellite galaxies of the Milky Way are very important both for the studies of the formation and evolution of galaxies and for the research on the dark matter problem. In the present review paper some structural properties of the Local Group, as well

A Study of Abundance Patterns in the Sextans and Sculptor Dwarf Spheroidal Galaxies

The Astrophysical Journal
In this work, we employ a multicomponent decomposition model to study the Sextans and Sculptor dwarf spheroidal galaxies, which have distinct evolutionary histories.
