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

open access: yesThe 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).

Chemical Abundances of Dwarf Galaxies [PDF]

open access: yes
Dwarf galaxies, though small in size, play a crucial role in understanding the chemical evolu- tion of galaxies. Dwarf galaxies make up the overwhelming majority of galaxies in our local group and have very low metallicities.

Extended Stellar Populations in Ultrafaint Dwarf Galaxies

open access: yesThe 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.

Dwarf Galaxy Integral-field Survey (DGIS): Survey Overview and the Results of a Global Mass–Metallicity Relation

open access: yesThe Astrophysical Journal Supplement Series
Low-mass galaxies are the building blocks of massive galaxies in the framework of hierarchical structure formation. To enable detailed studies of galactic ecosystems in dwarf galaxies by spatially resolving different galactic components, we have carried ...

A Luminous X-Ray Active Galactic Nucleus in the Dwarf–Dwarf Galaxy Merger RGG 66

open access: yesThe Astrophysical Journal
We present the discovery of a luminous X-ray active galactic nucleus (AGN) in the dwarf galaxy merger RGG 66. The black hole is predicted to have a mass of M _BH ∼ 10 ^5.4 M _⊙ and to be radiating close to its Eddington limit ( L _bol / L _Edd ∼ 0.75 ...
