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.

The Origin Of Dwarf Spheroidal Galaxies [PDF]
Symposium - International Astronomical Union, 1983 Two dwarf spheroidal galaxies are associated with the Magellanic Stream with their major axes oriented along it. Evidence suggests that all the dwarf spheroidal satellites of the Galaxy belong to one or other of two streams of tidal debris. If this is true the orbits will give the first reliable determination of the total mass of the Galaxy out to 120 ...

Star Forming Dwarf Galaxies [PDF]
, 2011 Star forming dwarf galaxies (SFDGs) have a high gas content and low metallicities, reminiscent of the basic entities in hierarchical galaxy formation scenarios. In the young universe they probably also played a major role in the cosmic reionization. Their abundant presence in the local volume and their youthful character make them ideal objects for ...

Angular Momentum in Dwarf Galaxies
Open 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 ...

MaNGA AGN dwarf galaxies (MAD)
Astronomy & AstrophysicsContext. Feedback from an active galactic nucleus (AGN) is one of the most important mechanisms in galaxy evolution. This phenomenon is usually found in massive galaxies and is known to regulate star formation. Although dwarf galaxies are assumed to be regulated by supernova feedback, recent studies have offered evidence to support the presence of AGN ...
