Discovery of a nova super-remnant surrounding the recurrent nova LMCN 1971-08a in the Large Magellanic Cloud
Michael W. Healy-Kalesh, Manami Sasaki, Sean D. Points +6
A nova super-remnant (NSR) is a greatly-extended structure grown by repeated nova eruptions sweeping the surrounding material away from a nova into a dense outer shell and are pred…
JWST/MIRI detection of [Ne V] and [Ne VI] in M83: Evidence for the long sought-after AGN?
Svea Hernandez, Linda J. Smith, Logan H. Jones +16
We report the first detections of [Ne V] 14.3 μm and [Ne VI] 7.7 μm at high confidence (S/N>=6) in the nuclear region of the nearby spiral galaxy M83. Emission line maps of these h…
The Dark Energy Camera Magellanic Clouds Emission-Line Survey
Sean D. Points, Knox S. Long, William P. Blair +7
We have used the Dark Energy Camera (DECam) on the CTIO Blanco 4-m telescope to perform a new emission-line survey of the Large Magellanic Cloud (LMC) using narrow-band H-alpha and…
Kinematics: A Clean Diagnostic for Separating Supernova Remnants from HII Regions in Nearby Galaxies
Sean D. Points, Knox S. Long, P. Frank Winkler +1
Many more supernova remnants (SNRs) are now known in external galaxies than in the Milky Way. Most of these SNRs have been identified using narrow-band imaging, separating SNRs fro…
A Spectroscopic Study of the Rich Supernova Remnant Population in M83
P. Frank Winkler, William P. Blair, Knox S. Long
We report the results from a spectrophotometric study sampling the roughly 300 candidate supernova remnants (SNRs) in M83 identified through optical imaging with Magellan/IMACS and…
A High-Resolution X-Ray and Optical Study of SN 1006: Asymmetric Expansion and Small-Scale Structure in a Type Ia Supernova Remnant
P. Frank Winkler, Brian J. Williams, Stephen P. Reynolds Robert Petre +3
We introduce a deep (670 ks) X-ray survey of the SN1006 remnant from Chandra, plus a deep H-alpha image from the 4m telescope at CTIO. Comparison with Chandra images from 2003 give…
