Intermediate-mass black holes in dwarf galaxies out to redshift ∼2.4 in the Chandra COSMOS-Legacy Survey [PDF]
, 2018 We present a sample of 40 AGN in dwarf galaxies at redshifts $z \lesssim$ 2.4. The galaxies are drawn from the \textit{Chandra} COSMOS-Legacy survey as having stellar masses $10^{7}\leq M_{*}\leq3 \times 10^{9}$ M$_{\odot}$.

Searching for Dark Matter Annihilation from Milky Way Dwarf Spheroidal Galaxies with Six Years of Fermi Large Area Telescope Data. [PDF]
Physical Review Letters, 2015 The dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are some of the most dark matter (DM) dominated objects known. We report on γ-ray observations of Milky Way dSphs based on six years of Fermi Large Area Telescope data processed with the ...

Be it therefore resolved: cosmological simulations of dwarf galaxies with 30 solar mass resolution [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study a suite of extremely high-resolution cosmological Feedback in Realistic Environments simulations of dwarf galaxies ($M_{\rm halo} \lesssim 10^{10}\rm \, M_{\odot }$), run to z = 0 with $30\, \mathrm{M}_{\odot }$ resolution, sufficient (for the

NIHAO XV: the environmental impact of the host galaxy on galactic satellite and field dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study the impact of the host on dwarf galaxy properties using four new Milky Way-like, ultra high-resolution simulations, ($N_{\rm part} >10^7$) from the NIHAO project. We split our sample in satellite ($R 2.5 R_{\rm 200}$) galaxies.

THE METALLICITY OF VOID DWARF GALAXIES [PDF]
The Astrophysical Journal, 2014 The current Lambda CDM cosmological model predicts that galaxy evolution proceeds more slowly in lower density environments, suggesting that voids are a prime location to search for relatively pristine galaxies that are representative of the building blocks of early massive galaxies.

Multimessenger Signatures of Massive Black Holes in Dwarf Galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Recent discoveries of massive black holes (MBHs) in dwarf galaxies suggest that they may have a more common presence than once thought. Systematic searches are revealing more candidates, but this process could be accelerated by predictions from ...

Substructure in Dwarf Galaxies [PDF]
Publications of the Astronomical Society of Australia, 2004 AbstractRecent years have seen a series of large-scale photometric surveys with the aim of detecting substructure in nearby dwarf galaxies. Some of these objects display a varying distribution of each stellar population, reflecting their star formation histories.

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.

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.
