The HETDEX Survey: Probing neutral hydrogen in the circumgalactic medium of ~88,000 Lyman Alpha Emitters
Mahan Mirza Khanlari, Karl Gebhardt, Laurel H. Weiss +12
We explore the neutral hydrogen (H I) gas around 1.9 < z < 3.5 Lyman Alpha Emitters (LAEs) from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) using faint Ly absorpt…
HST Emission Line Galaxies at z ~ 2: The Mystery of Neon
Gregory Zeimann, Robin Ciardullo, Henry Gebhardt +6
We use near-IR grism spectroscopy from the Hubble Space Telescope to examine the strength of [Ne~III] 3869 relative to H-beta, [O~II] 3727 and [O~III] 5007 in 236 low mass (7.5 < l…
HST Emission Line Galaxies at z ~ 2: The Ly-alpha Escape Fraction
Robin Ciardullo, Gregory Zeimann, Caryl Gronwall +8
We compare the H-beta line strengths of 1.90 < z < 2.35 star-forming galaxies observed with the near-IR grism of the Hubble Space Telescope with ground-based measurements of Ly-alp…
No More Active Galactic Nuclei in Clumpy Disks Than in Smooth Galaxies at z~2 in CANDELS / 3D-HST
Jonathan R. Trump, Guillermo Barro, Stephanie Juneau +23
We use CANDELS imaging, 3D-HST spectroscopy, and Chandra X-ray data to investigate if active galactic nuclei (AGNs) are preferentially fueled by violent disk instabilities funnelin…
The HETDEX Pilot Survey V: The Physical Origin of Lyman-alpha Emitters Probed by Near-infrared Spectroscopy
Mimi Song, Steven L. Finkelstein, Karl Gebhardt +19
We present the results from a VLT/SINFONI and Keck/NIRSPEC near-infrared spectroscopic survey of 16 Lyman-alpha emitters (LAEs) at = 2.1 - 2.5 in the COSMOS and GOODS-N fields…
3D-HST Emission Line Galaxies at z ~ 2: Discrepancies in the Optical/UV Star Formation Rates
Gregory R. Zeimann, Robin Ciardullo, Henry Gebhardt +6
We use Hubble Space Telescope near-IR grism spectroscopy to examine the H-beta line strengths of 260 star-forming galaxies in the redshift range 1.90 < z < 2.35. We show that at th…
