Ionized Gas Kinematics at High Resolution IV: Star Formation and a Rotating Core in the Medusa (NGC 4194)
Sara C. Beck, John Lacy, Jean Turner +2
NGC 4194 is a post-merger starburst known as The Medusa for its striking tidal features. We present here a detailed study of the structure and kinematics of ionized gas in the cent…
The Science Performance of JWST as Characterized in Commissioning
Jane Rigby, Marshall Perrin, Michael McElwain +623
This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performanc…
J1649+2635: A Grand-Design Spiral with a Large Double-Lobed Radio Source
Minnie Y. Mao, Frazer Owen, Ryan Duffin +10
We report the discovery of a grand-design spiral galaxy associated with a double-lobed radio source. J1649+2635 (z = 0.0545) is a red spiral galaxy with a prominent bulge that it i…
Radio Emission Associated with the ULX in Holmberg II
Neal A. Miller, Richard Mushotzky, Susan Neff
We report the detection of radio emission coincident with the ultraluminous X-ray source (ULX) in Holmberg II. The radio emission is diffuse and resolved, covering an area ~60 by 4…
Minkowski's Object: A Starburst Triggered by a Radio Jet, Revisited
Steve Croft, Wil van Breugel, Wim de Vries +8
We present neutral hydrogen, ultraviolet, optical and near-infrared imaging, and optical spectroscopy, of Minkowski's Object (MO), a star forming peculiar galaxy near NGC 541. The…
NGC 404, A Rejuvenated Lenticular Galaxy on a Merger-Induced, Blueward Excursion into the Green Valley
David A. Thilker, Luciana Bianchi, David Schiminovich +14
We have discovered recent star formation in the outermost portion (1-4x R_25) of the nearby lenticular (S0) galaxy NGC 404 using GALEX UV imaging. FUV-bright sources are strongly c…
Suppression of star formation in early-type galaxies by feedback from supermassive black holes
Kevin Schawinski, Sadegh Khochfar, Sugata Kaviraj +21
Detailed high-resolution observations of the innermost regions of nearby galaxies have revealed the presence of supermassive black holes1. These black holes may interact with their…
The detection of M-dwarf UV flare events in the GALEX data archives
Barry Y. Welsh, Jonathan M. Wheatley, Mark Seibert +13
We present the preliminary results from implementing a new software tool that enables inspection of time-tagged photon data for the astronomical sources contained within individual…
