Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles

open access: yesGalaxies, 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

Black Hole Feedback in Dwarf Galaxy Evolution [PDF]

open access: yes, 2020
In a scenario where all galaxies form and evolve with supermassive black holes in their centers, it is thought that these central black holes play a vital role in limiting the growth of massive galaxies. In order to extend our understanding of black hole

In Pursuit of the Least Luminous Galaxies

open access: yesAdvances 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

The baryonic Faber-Jackson relation and fundamental plane of galaxy groups, elliptical galaxies, and dwarf galaxies

open access: yesAstronomy & Astrophysics
The baryonic Faber-Jackson relation (BFJR) links the baryonic mass of pressure-supported systems to their mean velocity dispersion. For elliptical galaxies, the BFJR is thought to be a projection of the fundamental plane (FP), which includes the stellar ...

The early-type dwarf galaxy population of the Centaurus cluster

open access: yes, 2009
Aims. We present a photometric study of the early-type dwarf galaxy population of the Centaurus cluster, aiming at investigating the galaxy luminosity function (LF) and galaxy scaling relations down to the regime of galaxies with $M_V\sim -10$ mag.

A New Sample of Dwarf Galaxies with X-Ray-selected Active Galactic Nucleus Candidates from the eROSITA All-Sky Survey

open access: yesThe Astrophysical Journal
To investigate the population of massive black holes in dwarf galaxies, we conduct a systematic search for active galactic nuclei (AGNs) using data from the first data release of the eROSITA All-Sky Survey (eRASS). We crossmatch dwarf galaxy positions in

MEGATRON: how the first stars can create an iron metallicity plateau in the smallest dwarf galaxies

open access: yesThe Open Journal of Astrophysics
We study the stellar mass-iron metallicity relation of dwarf galaxies in the new high-resolution MEGATRON cosmological radiation-hydrodynamics simulations.

Numerical simulations of dwarf galaxy merger trees [PDF]

open access: yes, 2014
We investigate the evolution of dwarf galaxies using N-body/smoothed particle hydrodynamics simulations that incorporate their formation histories through merger trees constructed using the extended Press-Schechter formalism.

Active Dwarf Galaxy Database. II. Connections between Host Galaxy Properties and Black Hole Accretion Signatures

open access: yesThe Astrophysical Journal
We investigate the connection between accretion signatures and host galaxy properties in the context of how active dwarf galaxies are identified. We use the database constructed in E. J. Wasleske & V. F.
