H-alpha Star Formation Rates of the SHIELD Dwarf Galaxies
Madeline Shepley, David G. Gormanous, John J. Salzer +9
The Survey of HI in Extremely Low-mass Dwarfs (SHIELD) galaxy sample is an HI-selected catalog of galaxies that occupy the extreme low-mass end of the HI mass function. Our team is…
UV Star-Formation Rates of the SHIELD Dwarf Galaxies
David G. Gormanous, Anjali S. Dziarski, John J. Salzer +11
The Survey of HI in Extremely Low-mass Dwarfs (SHIELD) is a multi-wavelength observational project targeting gas-rich, star-forming dwarf galaxies at the faint end of the HI mass f…
A Multiwavelength View of Oph I: Resolving the X-ray Source Between A and B
Sean J. Gunderson, Jackson Codd, Walter W. Golay +12
We present a multiwavelength analysis of the central stellar pair of Oph, components A and B. Using recent high-resolution \textit{Chandra X-ray Observatory} observations, we d…
Hα Dots: Direct-Method Metal Abundances of Low-Luminosity Star-Forming Systems
Alec S. Hirschauer, John J. Salzer, Nathalie Haurberg +2
Utilizing low-luminosity star-forming systems discovered in the H Dots survey, we present spectroscopic observations undertaken using the KPNO 4m telescope for twenty-six source…
SHIELD: Neutral Gas Kinematics and Dynamics
Andrew T. McNichols, Yaron G. Teich, Elise Nims +22
We present kinematic analyses of the 12 galaxies in the "Survey of HI in Extremely Low-mass Dwarfs" (SHIELD). We use multi-configuration interferometric observations of the HI 21cm…
SHIELD: Comparing Gas and Star Formation in Low Mass Galaxies
Yaron G. Teich, Andrew T. McNichols, Elise Nims +22
We analyze the relationships between atomic, neutral hydrogen (HI) and star formation (SF) in the 12 low-mass SHIELD galaxies. We compare high spectral (~0.82 km/s/channel) and spa…
Oxygen Abundance Measurements of SHIELD Galaxies
Nathalie C. Haurberg, John J. Salzer, John M. Cannon +1
We have derived oxygen abundances for 8 galaxies from the Survey of HI in Extremely Low-mass Dwarfs (SHIELD). The SHIELD survey is an ongoing study of very low-mass galaxies, with…
ALFALFA Discovery of the Nearby Gas-Rich Dwarf Galaxy Leo~P. III. An Extremely Metal Deficient Galaxy
Evan D. Skillman, John J. Salzer, Danielle A. Berg +10
We present KPNO 4-m and LBT/MODS spectroscopic observations of an HII region in the nearby dwarf irregular galaxy Leo P discovered recently in the Arecibo ALFALFA survey. In both o…
ALFALFA Discovery of the Nearby Gas-Rich Dwarf Galaxy Leo~P. II. Optical Imaging Observations
Katherine L. Rhode, John J. Salzer, Nathalie C. Haurberg +8
We present results from ground-based optical imaging of a low-mass dwarf galaxy discovered by the ALFALFA 21-cm HI survey. Broadband (BVR) data obtained with the WIYN 3.5-m telesco…
Metal Abundances of 12 Dwarf Irregulars from the ADBS Survey
Nathalie C. Haurberg, Jessica Rosenberg, John J. Salzer
We have analyzed long-slit spectra of 12 dwarf irregular galaxies from the Arecibo Dual Beam Survey (ADBS). These galaxies represent a heterogeneous sample of objects detected by A…
UV-Bright Stellar Populations and Their Evolutionary Implications in the Collapsed-Core Cluster M15
Nathalie C. Haurberg, Gabriel M. G. Lubell, Haldan N. Cohn +4
We performed deep photometry of the central region of Galactic globular cluster M15 from archival Hubble Space Telescope data taken on the High Resolution Channel and Solar Blind C…
