The formation of ultra-compact dwarf galaxies and nucleated dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 Ultra compact dwarf galaxies (UCDs) have similar properties as massive globular clusters or the nuclei of nucleated galaxies. Recent observations suggesting a high dark matter content and a steep spatial distribution within groups and clusters provide new clues as to their origins.

DWARF GALAXIES AND THE COSMIC WEB [PDF]
The Astrophysical Journal, 2013 We use a cosmological simulation of the formation of the Local Group of Galaxies to identify a mechanism that enables the removal of baryons from low-mass halos without appealing to feedback or reionization. As the Local Group forms, matter bound to it develops a network of filaments and pancakes.

Satellites and haloes of dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mainly on bright primaries, our central galaxies span a wide range of stellar mass, 10^7.5 < M_*^pri/M_sun < 10^11, from dwarfs to central cluster galaxies.

The Pristine dwarf galaxy survey–V. The edges of the dwarf galaxy Hercules
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We present a new spectroscopic study of 175 stars in the vicinity of the dwarf galaxy Hercules (d ∼ 132 kpc) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Field multi-object system to solve the conundrum that whether Hercules is tidally disrupting.

The Interstellar Medium of Dwarf Galaxies [PDF]
Galaxies, 2022 Dwarf galaxies are by far the most numerous galaxies in the Universe, showing properties that are quite different from those of their larger and more luminous cousins. This review focuses on the physical and chemical properties of the interstellar medium of those dwarfs that are known to host significant amounts of gas and dust. The neutral and ionized

Galaxy threshing and the formation of ultra-compact dwarf galaxies [PDF]
, 2001 Recent spectroscopic and morphological observational studies of galaxies around NGC 1399 in the Fornax Cluster (Drinkwater et al. 2000b) have discovered several `ultra-compact dwarf' galaxies with intrinsic sizes of $\sim$ 100 pc and absolute $B$ band ...

The evolution of dwarf galaxies [PDF]
Astrophysics and Space Science, 1988 We propose an evolutionary model for dwarf galaxies in Which initially metal-poor gas-rich dwarf irregular (dI) galaxies evolve through bursting Blue Compact Dwarf(BCD) stages and eventually fade from the BCD phase to become dwarf ellipticals (dE). During the bursting phase the surface brightness of the galaxy increases rapidly due to enhanced OB star ...

Globular Clusters and the Halos of Dwarf Galaxies
Galaxies, 2017 Many dwarf galaxies have disproportionately rich globular cluster (GC) systems for their luminosities. Moreover, the GCs tend to be preferentially associated with the most metal-poor stellar populations in their parent galaxies, making them attractive ...
