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…
Discovery of an ultra-diffuse galaxy in the Pisces-Perseus supercluster
David Martinez-Delgado, Ronald Laesker, Margarita Sharina +16
We report the discovery of DGSAT I, an ultra-diffuse, quenched galaxy located 10.4 degrees in projection from the Andromeda galaxy (M31). This low-surface brightness galaxy (mu_V =…
HST Emission Line Galaxies at z ~ 2: Comparing Physical Properties of Lyman Alpha and Optical Emission Line Selected Galaxies
Alex Hagen, Gregory R. Zeimann, Christoph Behrens +14
We compare the physical and morphological properties of z ~ 2 Lyman-alpha emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z ~ 2…
Discovery of a stellar tidal stream around the Whale galaxy, NGC 4631
David Martinez-Delgado, Elena D'Onghia, Taylor S. Chonis +5
We report the discovery of a giant stellar tidal stream in the halo of NGC 4631, a nearby edge-on spiral galaxy interacting with the spiral NGC 4656, in deep images taken with a 40…
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…
Photometry of the Stellar Tidal Stream in the Halo of Messier 63
Taylor S. Chonis, David Martinez-Delgado, R. Jay Gabany +3
We present surface photometry of a giant, low surface brightness stellar arc in the halo of the nearby spiral galaxy M63 (NGC 5055) that is consistent with being a part of a stella…
A Petal of the Sunflower: Photometry of the Stellar Tidal Stream in the Halo of Messier 63 (NGC 5055)
Taylor S. Chonis, David Martinez-Delgado, R. Jay Gabany +4
We present surface photometry of a very faint, giant arc feature in the halo of the nearby spiral galaxy NGC 5055 (M63) that is consistent with being a part of a stellar stream res…
