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.

Dwarf Galaxies with the Highest Concentration Are Not Thicker than Ordinary Dwarf Galaxies
The Astrophysical Journal, 2023 Abstract The formation mechanism of high-concentration dwarf galaxies is still a mystery. We perform a comparative study of the intrinsic shape of nearby low-mass galaxies with different stellar concentration. The intrinsic shape is parameterized by the intermediate-to-major axis ratios B/A and the minor-to-major axis ratios C/A of ...

Thin disk of co-rotating dwarfs: a fingerprint of dissipative (mirror) dark matter? [PDF]
, 2013 Recent observations indicate that about half of the dwarf satellite galaxies around M31 orbit in a thin plane approximately aligned with the Milky Way. It has been argued that this observation along with several other features can be explained if these ...

Dark influences: imprints of dark satellites on dwarf galaxies [PDF]
, 2014 In the context of the current $\Lambda$CDM cosmological model small dark matter haloes are abundant and satellites of dwarf galaxies are expected to be predominantly dark.

Dwarf Galaxies in Voids: Dark Matter Halos and Gas Cooling [PDF]
, 2010 Galaxy surveys have shown that luminous galaxies are mainly distributed in large filaments and galaxy clusters. The remaining large volumes are virtually devoid of luminous galaxies.

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 ...

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

High-resolution mass models of dwarf galaxies from LITTLE THINGS [PDF]
, 2015 We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc.
