The Ecosystem Of Dwarf Galaxies

, 2017
It remains unclear what physical mechanisms are triggering starbursts in low-mass galaxies and what is the effect of stellar feedback in their shallow potential wells. We study a sample of 18 nearby starburst dwarfs using multi-wavelength data, including interferometric HI observations, HST imaging, and MUSE integral-field spectroscopy.

The Star Formation History in Local Group Galaxies. I. Ten Dwarf Galaxies

The Astrophysical Journal
The star formation histories (SFHs) of galaxies provide valuable insights into galaxy evolution and stellar physics. Understanding the SFHs enables the study of chemical enrichment of galaxies, star formation triggered by interactions, and the behavior ...

The Dwarf Satellites of M31 and the Galaxy [PDF]

The Astronomical Journal, 2006
The satellite systems of M31 and the Galaxy are compared. It is noted that all five of the suspected stripped dSph cores of M31 companions are located within a projected distance of 40 kpc of from the nucleus of this galaxy, whereas the normal dSph companions to this object have distances > 40 kpc from the center of M31.

Extended Stellar Populations in Ultrafaint Dwarf Galaxies

The Astronomical Journal
The possible existence of stellar halos in low-mass galaxies is being intensely discussed nowadays after some recent discoveries of stars located in the outskirts of dwarf galaxies of the Local Group.

A Search for Faint Resolved Galaxies Beyond the Milky Way in DES Year 6: A New Faint, Diffuse Dwarf Satellite of NGC 55

The Astrophysical Journal
We report results from a systematic wide-area search for faint dwarf galaxies at heliocentric distances from 0.3 to 2 Mpc using the full 6 yr of data from the Dark Energy Survey (DES).

Homogeneous Photometry VI: Variable Stars in the Leo I Dwarf Spheroidal Galaxy

, 2014
We have characterized the pulsation properties of 164 candidate RR Lyrae variables (RRLs) and 55 candidate Anomalous and/or short-period Cepheids in Leo I dwarf spheroidal galaxy.
