Cusp Disruption in Minor Mergers [PDF]
, 2001 We present 0.55 x 10^6 particle simulations of the accretion of high-density dwarf galaxies by low-density giant galaxies, using models that contain both power-law central density cusps and point masses representing supermassive black holes.

An r-process Enhanced Star in the Dwarf Galaxy Tucana III [PDF]
, 2017 Chemically peculiar stars in dwarf galaxies provide a window for exploring the birth environment of stars with varying chemical enrichment. We present a chemical abundance analysis of the brightest star in the newly discovered ultra-faint dwarf galaxy ...

Dwarf Spheroidal Galaxies [PDF]
Symposium - International Astronomical Union, 1994 Dwarf Spheroidal (dSph) galaxies are the faintest baryonic systems recognized as galaxies. Understanding the structure and stellar populations of these systems is critical for the modelling of their formation and evolution, and by extension, for understanding the general problem of galaxy formation ...

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

Dwarf Galaxies in the Local Volume [PDF]
Astrophysical Bulletin, 2018 AbstractThe Updated Nearby Galaxy Catalog (=UNGC) of 1047 Local Volume (=LV) galaxies, situated within a distance of 11 Mpc, contains 870 dwarfs, i.e. 5/6 of the sample. Almost 40% of them have accurate distances measured with Hubble Space Telescope. Most of the LV dwarfs have been observed in HI and Hα emission lines, as well in far-ultraviolet with ...

Ultradiffuse galaxies: the high-spin tail of the abundant dwarf galaxy population [PDF]
, 2016 Recent observations have revealed the existence of an abundant population of faint, low surface brightness (SB) galaxies, which appear to be numerous and ubiquitous in nearby galaxy clusters, including the Virgo, Coma and Fornax clusters.

Direct evidence of hierarchical assembly at low masses from isolated dwarf galaxy groups [PDF]
Nature Astronomy, 2017 The demographics of dwarf galaxy populations have long been in tension with predictions from the Λ cold dark matter (ΛCDM) paradigm1–4. If primordial density fluctuations were scale-free as predicted, dwarf galaxies should themselves host dark-matter ...
