A CANDIDATE MASSIVE BLACK HOLE IN THE LOW-METALLICITY DWARF GALAXY PAIR MRK 709 [PDF]
, 2014 The incidence and properties of present-day dwarf galaxies hosting massive black holes (BHs) can provide important constraints on the origin of high-redshift BH seeds.

It’s a Breeze: The Circumgalactic Medium of a Dwarf Galaxy Is Easy to Strip
The Astrophysical JournalThe circumgalactic medium (CGM) of star-forming dwarf galaxies plays a key role in regulating the galactic baryonic cycle. We investigate how susceptible the CGM of dwarf satellite galaxies is to ram pressure stripping in Milky Way–like environments.

Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles
Galaxies, 2016 Dwarf galaxies of the Local Group provide unique possibilities to test current theories of structure formation. Their number and properties have put the broadly accepted cold dark matter model into question, posing a few problems. These problems now seem

Dwarf Galaxies in Voids: Dark Matter Halos and Gas Cooling
Advances in Astronomy, 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.

In Pursuit of the Least Luminous Galaxies
Advances in Astronomy, 2010 The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10−7LMW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass

A Possible “Too-many-satellites” Problem in the Isolated Dwarf Galaxy DDO 161
The Astrophysical Journal LettersThe abundance of satellite galaxies provides a direct test of ΛCDM and galaxy formation physics on small scales. While satellites of Milky Way-mass galaxies are well studied, those of dwarf galaxies remain largely unexplored.

Forecasts for Galaxy Formation and Dark Matter Constraints from Dwarf Galaxy Surveys
The Astrophysical JournalThe abundance of faint dwarf galaxies is determined by the underlying population of low-mass dark matter (DM) halos and the efficiency of galaxy formation in these systems. Here, we quantify potential galaxy formation and DM constraints from future dwarf
