Dwarf elliptical galaxies

open access: yesThe Astrophysical Journal, 1983
We propose that dwarf elliptical galaxies are the bound remnants of more massive stellar systems, such as a parent galaxy which has lost more than half its mass in gas ejection during a burst of star formation, or an unbound tidal debris produced during the interaction of two giant galaxies.

Star Forming Dwarf Galaxies [PDF]

open access: yes, 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 ...

The High-mass X-Ray Binary Luminosity Functions of Dwarf Galaxies

open access: yesThe Astrophysical Journal
Drawing from the Chandra archive and using a carefully selected set of nearby dwarf galaxies, we present a calibrated high-mass X-ray binary (HMXB) luminosity function in the low-mass galaxy regime and search for an already hinted at dependence on ...

Rare Occasions: Tidal Disruption Events Rarely Power the AGNs Observed in Dwarf Galaxies

open access: yesThe Astrophysical Journal
Tidal disruption events (TDEs) could be an important growth channel for massive black holes in dwarf galaxies. Theoretical work suggests that the observed active galactic nuclei (AGNs) in dwarf galaxies are predominantly TDE-powered. To assess this claim,

The puzzling assembly of the Milky Way halo – contributions from dwarf Spheroidals and globular clusters

open access: yesEPJ Web of Conferences, 2012
While recent sky surveys have uncovered large numbers of ever fainter Milky Way satellites, their classification as star clusters, low-luminosity galaxies, or tidal overdensities remains often unclear. Likewise, their contributions to the build-up of the

Isolated dwarf galaxies in the local supercluster and its surroundings [PDF]

open access: yesarXiv, 2011
We present a list of 75 isolated late-type dwarf galaxies which have no neighbors with a relative radial velocity difference of less than 500 km/s or projected separations within 500 kpc. These were selected from $\sim$2000 dwarf galaxies with radial velocities $V_{LG}<3500$ km/s within the volume of the Local supercluster.
