THE OBSERVED PROPERTIES OF DWARF GALAXIES IN AND AROUND THE LOCAL GROUP [PDF]

open access: yes, 2012
Positional, structural, and dynamical parameters for all dwarf galaxies in and around the Local Group are presented, and various aspects of our observational understanding of this volume-limited sample are discussed.

Dark matter heats up in dwarf galaxies [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
Gravitational potential fluctuations driven by bursty star formation can kinematically ‘heat up’ dark matter at the centres of dwarf galaxies. A key prediction of such models is that, at a fixed dark matter halo mass, dwarfs with a higher stellar mass ...

An Overview of the Dwarf Galaxy Survey [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 2013
The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and draws to this a rich database of a wide range of wavelengths tracing the dust, gas and stars.

The Relationship between Slope and Luminosity [PDF]

open access: yesKirkuk Journal of Science, 2010
In this study, a sample of galaxies has been adopted. It consists of 112 elliptical galaxies, among them were 56 dwarf elliptical galaxies, which belong to virgo cluster, 37 normal galaxies and 19 bright galaxies. Also, surface brightness profiles fitted

Be it therefore resolved: cosmological simulations of dwarf galaxies with 30 solar mass resolution [PDF]

open access: yesMonthly 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

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers

open access: yesThe Astrophysical Journal, 2023
Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

Multimessenger Signatures of Massive Black Holes in Dwarf Galaxies [PDF]

open access: yesMonthly 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 ...

DWARF GALAXIES AND THE COSMIC WEB [PDF]

open access: yesThe Astrophysical Journal, 2013
We use a cosmological simulation of the formation of the Local Group of Galaxies to identify a mechanism that enables the removal of baryons from low-mass halos without appealing to feedback or reionization. As the Local Group forms, matter bound to it develops a network of filaments and pancakes.

AGN-Driven Outflows in Dwarf Galaxies [PDF]

open access: yesAstrophysical Journal, 2019
We present spatially resolved kinematic measurements of active galactic nucleus (AGN)-driven outflows in dwarf galaxies in the stellar mass range ∼6 × 108–9 × 109 M⊙, selected from SDSS DR7 and DR8 and followed-up with Keck/LRIS spectroscopy.
