Pushing back the limits: detailed properties of dwarf galaxies in a ΛCDM universe [PDF]
Astronomy & Astrophysics, 2018 We present the results of a set of high-resolution chemo-dynamical simulations of dwarf galaxies in a ΛCDM cosmology. Out of an original (3.4 Mpc/h)3 cosmological box, a sample of 27 systems are re-simulated from z = 70 to z = 0 using a zoom-in technique.

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 Fornax Deep Survey (FDS) with VST. VI. Optical properties of the dwarf galaxies in the Fornax cluster [PDF]
, 2019 The Fornax Deep Survey Dwarf galaxy Catalog (FDSDC) includes 564 dwarf galaxies in the Fornax cluster and the in-falling Fornax A subgroup. We use the FDSDC galaxies for statistical analysis of the structural and stellar population differences in the ...

A Catalog of Merging Dwarf Galaxies in the Local Universe [PDF]
Astrophysical Journal Supplement Series, 2018 We present the largest publicly available catalog of interacting dwarf galaxies. It includes 177 nearby merging dwarf galaxies of stellar mass M* < 1010 M⊙ and redshifts z < 0.02.

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.

Reignition of star formation in dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The Local Group hosts a number of star-forming dwarf galaxies that show evidence of periods of little to no star formation. We use a suite of cosmological simulations to study how star formation is reignited in such galaxies.

Dwarf spheroidal galaxies: Keystones of galaxy evolution [PDF]
Publications of the Astronomical Society of the Pacific, 1994 Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies. We discuss the present observational data and their implications for theories of the formation and evolution of both dwarf
