Characteristic size and mass of galaxies in the Bose–Einstein condensate dark matter model
Physics Letters B, 2016 We study the characteristic length scale of galactic halos in the Bose–Einstein condensate (or scalar field) dark matter model. Considering the evolution of the density perturbation we show that the average background matter density determines the ...

The Faintest Dwarf Galaxies [PDF]
Annual Review of Astronomy and Astrophysics, 2019 The lowest luminosity ([Formula: see text] L[Formula: see text]) Milky Way satellite galaxies represent the extreme lower limit of the galaxy luminosity function. These ultra-faint dwarfs are the oldest, most dark matter–dominated, most metal-poor, and least chemically evolved stellar systems known.

Morphological transformation of dwarf galaxies in the Local Group [PDF]
, 2015 In the Local Group there are three main types of dwarf galaxies: Dwarf Irregulars, Dwarf Spheroidals, and Dwarf Ellipticals. Intermediate/transitional types are present as well.

THE METALLICITY OF VOID DWARF GALAXIES [PDF]
The Astrophysical Journal, 2014 The current Lambda CDM cosmological model predicts that galaxy evolution proceeds more slowly in lower density environments, suggesting that voids are a prime location to search for relatively pristine galaxies that are representative of the building blocks of early massive galaxies.

The Astrophysical Journal, 2023 Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which

Substructure in Dwarf Galaxies [PDF]
Publications of the Astronomical Society of Australia, 2004 AbstractRecent 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 PAndAS View of the Andromeda Satellite System. IV. Global Properties
The Astrophysical Journal, 2023 We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf galaxies located in the Pan-Andromeda Archaelogical Survey (PAndAS) and the previously ...

The Evolutionary Status of Isolated Dwarf Irregular Galaxies II. Star Formation Histories and Gas Depletion [PDF]
, 2001 The results of UBV and H alpha imaging of a large sample of isolated dwarf irregular galaxies are interpreted in the context of composite stellar population models.
