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$_{\odot}$.

A global analysis of dark matter signals from 27 dwarf spheroidal galaxies using 11 years of Fermi-LAT observations [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We search for a dark matter signal in 11 years of Fermi-LAT gamma-ray data from 27 Milky Way dwarf spheroidal galaxies with spectroscopically measured J-factors.

Dwarf Spheroidal Galaxies [PDF]
Symposium - International Astronomical Union, 1994 Dwarf Spheroidal (dSph) galaxies are the faintest baryonic systems recognized as galaxies. Understanding the structure and stellar populations of these systems is critical for the modelling of their formation and evolution, and by extension, for understanding the general problem of galaxy formation ...

NUCLEI OF EARLY-TYPE DWARF GALAXIES: ARE THEY PROGENITORS OF ULTRACOMPACT DWARF GALAXIES? [PDF]
The Astrophysical Journal, 2010 To address the question of whether the so-called ultracompact dwarf galaxies (UCDs) are the remnant nuclei of destroyed early-type dwarf galaxies (dEs), we analyze the stellar population parameters of the nuclei of 34 Virgo dEs, as well as 10 Virgo UCDs, including one that we discovered and which we report on here.

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

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 ...

On the dynamics of the Sagittarius dwarf galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 We use numerical simulations to test the feasibility of the suggestion by Ibata et al. (1994) that the excess population of stars which they discovered in the Sagittarius region may be the disrupted remains of a dwarf spheroidal galaxy. We find that a Fornax-like model for the pre-disruption system can indeed reproduce the data.

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.
