Angular Momentum in Dwarf Galaxies

open access: yesOpen Astronomy, 2014
AbstractWe study the “angular momentum catastrophe” in the framework of interaction among baryons and dark matter through dynamical friction. By means of Del Popolo (2009) model we simulate 14 galaxies similar to those investigated by van den Bosch, Burkert and Swaters (2001), and calculate the distribution of their spin parameters and the angular ...

Dwarf spheroidal galaxies in the M81 group of galaxies [PDF]

open access: yes, 2009
We study the properties of the dwarf galaxy population in the nearby interacting M81 group of galaxies. In particular, we are deriving the metallicity distribution functions, the ages and the star formation histories of these dwarf galaxies based on data

Unveiling the lowest surface brightness regions in dwarf galaxies: a machine learning approach with Gaia early DR3 [PDF]

open access: yes
openRecent observations suggest that dwarf galaxies appear to host extended tidal structures or debris from disrupted systems that contribute to their stellar halos.

The Blue Straggler Population in Dwarf Galaxies [PDF]

open access: yes, 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 ...

: Early Release Observations – Interplay between dwarf galaxies and their globular clusters in the Perseus galaxy cluster [PDF]

open access: yes
We present an analysis of globular clusters (GCs) of dwarf galaxies in the Perseus galaxy cluster that explores the relationship between dwarf galaxy properties and their GCs.

Low CO luminosities in dwarf galaxies [PDF]

open access: yes, 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 ...

APOGEE chemical abundances of stars in the Milky Way satellites Fornax, Sextans, Draco, and Carina

open access: yesAstronomy & Astrophysics
During 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]

open access: yesAnnual 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.
