Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers
The Astrophysical Journal, 2023 Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

Evolution of dwarf galaxies: a dynamical perspective [PDF]
Astronomy & Astrophysics, 2014 For a rotating galaxy, the inner circular-velocity gradient d_{R}V(0) provides a direct estimate of the central dynamical mass density, including gas, stars, and dark matter. We consider 60 low-mass galaxies with high-quality HI and/or stellar rotation curves (including starbursting dwarfs, irregulars, and spheroidals), and estimate d_{R}V(0) as V(R_d)/

The cores of dwarf galaxy haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 1996 We use N-body simulations to examine the effects of mass outflows on the density profiles of cold dark matter (CDM) halos surrounding dwarf galaxies. In particular, we investigate the consequences of supernova-driven winds that expel a large fraction of the baryonic component from a dwarf galaxy disk after a vigorous episode of star formation.

Faint Dwarf galaxies in nearby WINGS clusters: photometric characterization [PDF]
, 2019 In the cores of galaxy clusters there is a population of lows-mass stellar systems such as dwarf Early-type galaxies, ultra-compact dwarf galaxies (UCDs) and ultra diffuse dwarf galaxies. We present here the photometric and morphological characterization

Understanding the Extreme Classes of Dwarf Galaxies [PDF]
, 2022 Most of the research on dwarf galaxies in the past has focused on the detailed properties of nearby systems or the most commonly occurring types of dwarfs.

Dust in Nearby DWARF Galaxies [PDF]
Symposium - International Astronomical Union, 1994 The aim of the present paper is to look for the gas-to-dust ratio in different types of galaxies and for a correlation between this ratio and the metallicity in dwarf galaxies. The recent compilation of data on nearby galaxies by Schmidt & Boller (1992, hereinafter SB) including HI and dust ...

Ultra-Compact Dwarf Galaxies in Galaxy Clusters [PDF]
Publications of the Astronomical Society of Australia, 2004 AbstractWe review the evidence that the ultra-compact dwarf (UCD) galaxies we recently discovered in the Fornax Cluster form a new, previously unknown class of galaxies and we discuss possible scenarios for their formation. We then present recent results that UCDs are also present in the Virgo Cluster, and that there is a much larger than expected ...

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 ...
