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 Energetics of Launching the Most Powerful Jets in Quasars: A Study of 3C82

Brian Punsly, Gary J. Hill, Paola Marziani +5

3C 82 at a redshift of 2.87 is the most distant 3C (Third Cambridge Catalogue) quasar. Thus, it is a strong candidate to have the most luminous radio lobes in the Universe. 3C 82 b…

HETDEX Pilot Survey. VI. [OIII] Emitters and Expectations for a Local Sample of Star Forming Galaxies in HETDEX

Briana Indahl, Greg Zeimann, Gary J. Hill +8

We assemble an unbiased sample of 29 galaxies with [O II] and/or [O III] detections at from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Pi…

The nature of faint radio galaxies at high redshifts

A. Saxena, H. J. A. Röttgering, K. J. Duncan +9

We present spectra and near-infrared images of a sample of faint radio sources initially selected as promising high-redshift radio galaxy (HzRG) candidates. We have determined reds…

Broad absorption line disappearance/emergence in multiple ions in a weak emission-line quasar

Weimin Yi, M. Vivek, W. N. Brandt +9

We report the discovery of disappearance of Mg ii, Al iii, C iv, and Si iv broad absorption lines (BALs) at the same velocity, accompanied by a new Civ BAL emerging at a higher vel…

The True Luminosities of Planetary Nebulae in M31's Bulge: Massive Central Stars from an Old Stellar Population

Brian D. Davis, Robin Ciardullo, George H. Jacoby +2

We measure the Balmer decrements of 23 of the brightest planetary nebulae (PNe) in the inner bulge ( arcmin) of M31 and de-redden the bright end of the region's [O II…
