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 ...

A Comparison of Outflow Properties in AGN Dwarfs versus Star-forming Dwarfs
The Astrophysical Journal, 2023 Feedback likely plays a crucial role in resolving discrepancies between observations and theoretical predictions of dwarf galaxy properties. Stellar feedback was once believed to be sufficient to explain these discrepancies, but it has thus far failed to

Metallic Winds in Dwarf Galaxies [PDF]
The Astrophysical Journal, 2017 Abstract We present results from models of galactic winds driven by energy injected from nuclear (at the galactic center) and non-nuclear starbursts. The total energy of the starburst is provided by very massive young stellar clusters, which can push the galactic interstellar medium and produce an important outflow. Such outflow can be a
