Local low-metallicity dwarf galaxies are relics of the early universe and are thought to hold clues into the origins of supermassive black holes. While recent studies are uncovering a growing population of active galactic nuclei (AGNs) in dwarf galaxies,

SPATIAL CORRELATION BETWEEN DUST AND Hα EMISSION IN DWARF IRREGULAR GALAXIES* [PDF]
Using a sample of dwarf irregular galaxies selected from the ALFALFA blind H i-survey and observed using the VIMOS IFU, we investigate the relationship between Hα emission and Balmer optical depth ( ). We find a positive correlation between Hα luminosity

Constraints on cross section and lifetime of dark matter with HAWC Observations of dwarf Irregular galaxies [PDF]
It has been shown that the dynamics of dwarf Irregular (dIrr) galaxies are dominated by dark matter. It is also observed that these galaxies have low star formation rates and metallicities, and no gamma-ray emission at ultra very high energies is ...

The Isaac Newton Telescope Monitoring project: Stellar population in the IC 10 dwarf irregular galaxy [PDF]
We have conducted an optical monitoring survey of IC 10 dwarf irregular galaxy in the Local Group, using the Isaac Newton Telescope (INT) with the wide-field camera (WFC), to identify the Asymptotic Giant Branch stars (AGBs).

The Star Formation Across Cosmic Time (SFACT) survey is a new narrowband survey designed to detect emission-line galaxies (ELGs) and quasi-stellar objects (QSOs) over a wide range of redshifts in discrete redshift windows.

The Interstellar Medium of Dwarf Galaxies
Dwarf galaxies are by far the most numerous galaxies in the Universe, showing properties that are quite different from those of their larger and more luminous cousins. This review focuses on the physical and chemical properties of the interstellar medium

Massive stars in the Sagittarius Dwarf Irregular Galaxy [PDF]
Abstract Low metallicity massive stars hold the key to interpret numerous processes in the past Universe including re–ionization, starburst galaxies, high-redshift supernovae, and γ-ray bursts. The Sagittarius Dwarf Irregular Galaxy [SagDIG, 12+log(O/H) = 7.37] represents an important landmark in the quest for analogues accessible with ...

Stellar Populations of Dwarf Irregular Galaxies [PDF]
We recently completed two-color CCD photometry of resolved stars in 11 dwarf irregular galaxies (Hopp & Schulte-Ladbeck, 1995, A&AS 111, 527), selected because of their relative isolation from massive galaxies in the Kran-Korteweg – Tammann sample (1979, AN 300, 181).
