Detection of Extensive Optical Emission from the Extremely Radio Faint Galactic Supernova Remnant G182.4+4.3
Robert Fesen, Jack Neustadt, Thomas How +1
Wide-field Halpha images of the radio faint Galactic supernova remnant G182.4+4.2 reveal a surprisingly extensive and complex emission structure, with an unusual series of broad an…
Narrow Transient Absorptions in Late-Time Optical Spectra of Type Ia Supernovae: Evidence for Large Clumps of Iron-Rich Ejecta?
Christine S. Black, Robert A. Fesen, Jerod T. Parrent
An examination of late-time, optical spectra of type Ia supernovae revealed surprisingly narrow absorption features which only become visible a few months after maximum light. Thes…
Optical Emission Associated with the Galactic Supernova Remnant G179.0+2.6
Thomas How, Robert Fesen, Jack Neustadt +2
Narrow passband optical images of the large Galactic supernova remnant G179.0+2.6 reveal a faint but nearly complete emission shell dominated by strong [O III] 4959,5007 A line emi…
A Distance Estimate to the Cygnus Loop Based on the Distances to Two Stars Located Within the Remnant
Robert A. Fesen, Jack M. M. Neustadt, Christine S. Black +1
Underlying nearly every quantitative discussion of the Cygnus Loop supernova remnant is uncertainty about its distance. Here we present optical images and spectra of nebulosities a…
The Transition of a Type IIL Supernova into a Supernova Remnant: Late-time Observations of SN 2013by
C. S. Black, D. Milisavljevic, R. Margutti +3
We present early-time Swift and Chandra X-ray data along with late-time optical and near-infrared observations of SN 2013by, a Type IIL supernova (SN) that occurred in the nearby s…
