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.

Globular Clusters and Dwarf Spheroidal Galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2007 Traditionally globular clusters and dwarf spheroidal galaxies have been distinguished by using one or more of the following criteria: (1) mass, (2) luminosity, (3) size, (4) mass-to-light ratio and (5) spread in metallicity.

Dwarf Spheroidal Galaxies : Keystones of Galaxy Evolution [PDF]
Publications of the Astronomical Society of the Pacific, 1994 Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies. We discuss the present

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 ...

Dependence of stellar substructures in M31 type galaxy on satellite morphology in galaxy mergers [PDF]
Serbian Astronomical Journal, 2022 Stellar streams and shells are observed in halos of spiral galaxies. In this paper, we investigated the formation of these structures due to mergers between the host spiral galaxy and its dwarf satellite galaxies.

Manganese in dwarf spheroidal galaxies [PDF]
Astronomy & Astrophysics, 2012 We provide manganese abundances (corrected for the effect of the hyperfine structure) for a large number of stars in the dwarf spheroidal galaxies Sculptor and Fornax and for a smaller number in the Carina and Sextans dSph galaxies. Abundances had already been determined for a number of other elements in these galaxies including a and iron peak ones ...

Searching for TeV Dark Matter in Irregular Dwarf Galaxies with HAWC Observatory
The Astrophysical Journal, 2023 We present the results of dark matter (DM) searches in a sample of 31 dwarf irregular (dIrr) galaxies within the field of view of the HAWC Observatory.

Mass Modelling of dwarf Spheroidal Galaxies [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe study the origin and properties of unbound stars in the kinematic samples of dwarf spheroidal galaxies. For this purpose we have run a high resolution N-body simulation of a two-component dwarf galaxy orbiting in a Milky Way potential. We create mock kinematic data sets by observing the dwarf in different directions.
