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…
High resolution near-infrared spectroscopy of a flare around the ultracool dwarf vB 10
Shubham Kanodia, Lawrence W. Ramsey, Marissa Maney +20
We present high-resolution observations of a flaring event in the M8 dwarf vB 10 using the near-infrared Habitable zone Planet Finder (HPF) spectrograph on the Hobby Eberly Telesco…
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Survey Design, Reductions, and Detections
Karl Gebhardt, Erin Mentuch Cooper, Robin Ciardullo +60
We describe the survey design, calibration, commissioning, and emission-line detection algorithms for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). The goal of HETDEX…
The HETDEX Instrumentation: Hobby-Eberly Telescope Wide Field Upgrade and VIRUS
Gary J. Hill, Hanshin Lee, Phillip J. MacQueen +46
The Hobby-Eberly Telescope (HET) Dark Energy Experiment (HETDEX) is undertaking a blind wide-field low-resolution spectroscopic survey of 540 square degrees of sky to identify and…
The ALFALFA Almost-Dark Galaxy AGC~229101: A Two Billion Solar Mass HI Cloud with a Very Low Surface Brightness Optical Counterpart
Lukas Leisman, Katherine L. Rhode, Catherine Ball +11
We present results from deep HI and optical imaging of AGC 229101, an unusual HI source detected at v = 7116 km/s in the ALFALFA survey. Initially classified as a can…
HETDEX [OIII] Emitters I: A spectroscopically selected low-redshift population of low-mass, low-metallicity galaxies
Briana Indahl, Greg Zeimann, Gary J. Hill +16
We assemble a sample of 17 low metallicity (7.45 < log(O/H)+12 < 8.12) galaxies with z < 0.1 found spectroscopically, without photometric pre-selection, in early data from the Hobb…
The HETDEX Survey: The Ly Escape Fraction from 3D-HST Emission Line Galaxies at
Laurel H. Weiss, William P. Bowman, Robin Ciardullo +13
We measure the Ly escape fraction of 935 [OIII]-emitting galaxies between by comparing stacked spectra from the Hubble Space Telescope/WFC3's near-IR grism to c…
A Harsh Test of Far-Field Scrambling with the Habitable Zone Planet Finder and the Hobby Eberly Telescope
Shubham Kanodia, Samuel Halverson, Joe P. Ninan +18
The Habitable zone Planet Finder (HPF) is a fiber fed precise radial velocity spectrograph at the 10 m Hobby Eberly Telescope (HET). Due to its fixed altitude design, the HET pupil…
