Unveiling the lowest surface brightness regions in dwarf galaxies: a machine learning approach with Gaia early DR3 [PDF]
openRecent observations suggest that dwarf galaxies appear to host extended tidal structures or debris from disrupted systems that contribute to their stellar halos.

Substructure in Dwarf Galaxies
, 2015 Recent years have seen a series of large-scale photometric surveys with the aim of detecting substructure in nearby dwarf galaxies. Some of these objects display a varying distribution of each stellar population, reflecting their star formation histories.

The Blue Straggler Population in Dwarf Galaxies [PDF]
, 2015 In this chapter I review the recent developments regarding the study of Blue Stragglers (BSS) in dwarf galaxies. The loose density environment of dwarf galaxies resembles that of the Galactic Halo, hence it is natural to compare their common BSS ...

Environmental effects on associations of dwarf galaxies
, 2023 We study the properties of associations of dwarf galaxies and their dependence on the environment. Associations of dwarf galaxies are extended systems composed exclusively of dwarf galaxies, considering as dwarf galaxies those galaxies less massive than $

Secondary evolution of galaxies investigated by N-body simulations
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

APOGEE chemical abundances of stars in the Milky Way satellites Fornax, Sextans, Draco, and Carina
Astronomy & AstrophysicsDuring its evolution, the Milky Way (MW) incorporated numerous dwarf galaxies, particularly low-mass systems. The surviving dwarf galaxies orbiting the MW serve as exceptional laboratories for studying the unique properties of these systems.

DWARF GALAXIES OF THE LOCAL GROUP [PDF]
Annual Review of Astronomy and Astrophysics, 1998 ▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs based on the most recent distance and radial velocity determinations.

Low CO luminosities in dwarf galaxies [PDF]
, 2012 We present maps of (12)COJ = 2-1 emission covering the entire star-forming disks of 16 nearby dwarf galaxies observed by the IRAM HERACLES survey. The data have 13 '' angular resolution, similar to 250 pc at our average distance of D = 4 Mpc, and sample ...
