The Herschel Dwarf Galaxy Survey - I. Properties of the low-metallicity ISM from PACS spectroscopy [PDF]
, 2015 Context. The far-infrared (FIR) lines are important tracers of the cooling and physical conditions of the interstellar medium (ISM) and are rapidly becoming workhorse diagnostics for galaxies throughout the universe.

Dust in Nearby DWARF Galaxies [PDF]
Symposium - International Astronomical Union, 1994 The aim of the present paper is to look for the gas-to-dust ratio in different types of galaxies and for a correlation between this ratio and the metallicity in dwarf galaxies. The recent compilation of data on nearby galaxies by Schmidt & Boller (1992, hereinafter SB) including HI and dust ...

An Accreting Supermassive Black Hole Buried in a Faint Dwarf Galaxy
The Astrophysical Journal LettersIn the last decade, there have been several discoveries of active galactic nuclei (AGN) in dwarf galaxies including an AGN in an ultracompact dwarf galaxy with a black hole mass >10 ^6 M _⊙ .

The unexpected diversity of dwarf galaxy rotation curves [PDF]
, 2015 We examine the circular velocity profiles of galaxies in A cold dark matter (CDM) cosmological hydrodynamical simulations from the EAGLE and LOCAL GROUPS projects and compare them with a compilation of observed rotation curves of galaxies spanning a wide

Star Forming Dwarf Galaxies [PDF]
, 2011 Star forming dwarf galaxies (SFDGs) have a high gas content and low metallicities, reminiscent of the basic entities in hierarchical galaxy formation scenarios. In the young universe they probably also played a major role in the cosmic reionization. Their abundant presence in the local volume and their youthful character make them ideal objects for ...

STELLAR KINEMATICS AND METALLICITIES IN THE ULTRA-FAINT DWARF GALAXY RETICULUM II [PDF]
, 2015 We present Magellan/M2FS, Very Large Telescope/GIRAFFE, and Gemini South/GMOS spectroscopy of the newly discovered Milky Way satellite Reticulum II. Based on the spectra of 25 Ret II member stars selected from Dark Energy Survey imaging, we measure a ...

Discovery of a Double-core Dwarf Galaxy in a Major Wet Merger: MCG+08-16-005
The Astronomical JournalI present the discovery of a dwarf galaxy with double cores, MCG+08-16-005, observed by an Integral Field Unit. Based on photometric and spatially resolved spectroscopic analyses, the galaxy is suggested as an ongoing dwarf-dwarf merger. MCG+08-16-005 is

DGSAT: Dwarf Galaxy Survey with Amateur Telescopes I. Discovery of low surface brightness systems around nearby spiral galaxies [PDF]
, 2015 Context: We introduce the Dwarf Galaxy Survey with Amateur Telescopes (DGSAT) project and report the discovery of eleven low surface brightness (LSB) galaxies in the fields of the nearby galaxies NGC 2683, NGC 3628, NGC 4594 (M104), NGC 4631, NGC 5457 ...

New dwarf galaxy candidates in the Centaurus group [PDF]
, 2015 Recent studies of the distribution and kinematics of the Milky Way and Andromeda satellite galaxy systems have confirmed the existence of coplanar, corotating structures of galaxies. In addition to the 'missing satellite problem', these structures pose a

Energy Evolution in the Progenitor of Galaxy Shells: A Semi-analytical Model
The Astrophysical JournalThe stellar shells surrounding an elliptical galaxy, as remnants of a dwarf galaxy disrupted during merging, reveal the distribution of energy and angular momentum of the progenitor dwarf galaxy. We develop a semi-analytical model to describe the changes
