The Crab Nebula Revisited Using HST/WFC3
William P. Blair, Ravi Sankrit, Dan Milisavljevic +5
It has been over 24 years since the iconic Crab Nebula has been visited by the high spatial resolution eye of the Hubble Space Telescope. The expanding nebula is dynamic on these t…
The Optical Evolution of the Tycho Supernova Remnant over Three Decades
P. Frank Winkler, Joseph Putko, William P. Blair
We report a series of images of the Tycho supernova remnant at eight epochs extending over thirty years: 1986-2016. In addition to our Hα images, we have obtained matched continuum…
Chandra Large Project Observations of the Supernova Remnant N132D: Measuring the Expansion of the Forward Shock
Xi Long, Paul P. Plucinsky, Terrance J. Gaetz +15
We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of t…
Optimizing Convolution Direction and Template Selection for Difference Image Analysis
Rodrigo Angulo, Armin Rest, William P. Blair +8
Difference image analysis (DIA) is a powerful tool for studying time-variable phenomena, and has been used by many time-domain surveys. Most DIA algorithms involve matching the spa…
A JWST/MIRI View of the ISM in M83: I. Resolved Molecular Hydrogen Properties, Star Formation, and Feedback
Logan H. Jones, Svea Hernandez, Linda J. Smith +11
We present a spatially-resolved (~3 pc pix) analysis of the distribution, kinematics, and excitation of warm H2 gas in the nuclear starburst region of M83. Our JWST/MIRI IFU…
The Green Monster hiding in front of Cas A: JWST reveals a dense and dusty circumstellar structure pockmarked by ejecta interactions
Ilse De Looze, Dan Milisavljevic, Tea Temim +27
JWST observations of the young Galactic supernova remnant Cassiopeia A revealed an unexpected structure seen as a green emission feature in colored composite MIRI F1130W and F1280W…
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…
Shockingly Bright Warm Carbon Monoxide Molecular Features in the Supernova Remnant Cassiopeia A Revealed by JWST
J. Rho, S. -H. Park, R. Arendt +36
We present JWST NIRCam (F356W and F444W filters) and MIRI (F770W) images and NIRSpec- IFU spectroscopy of the young supernova remnant Cassiopeia A (Cas A). We obtained the data as…
Dissecting the Crab Nebula with JWST: Pulsar wind, dusty filaments, and Ni/Fe abundance constraints on the explosion mechanism
Tea Temim, J. Martin Laming, P. J. Kavanagh +19
We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics, plus MIRI/MRS IFU spectra t…
The Supernova Remnant Population of NGC6946 as Observed in [Fe II] 1.644 m with HST
Knox S. Long, William P. Blair, P. Frank Winkler +1
NGC6946 is a high star formation rate face-on spiral galaxy that has hosted ten supernovae since 1917. Not surprisingly, a large number of supernova remnants and candidates have be…
A New, Larger Sample of Supernova Remnants in NGC 6946
Knox S. Long, P. Frank Winkler, William P. Blair
The relatively nearby spiral galaxy NGC~6946 is one of the most actively star forming galaxies in the local Universe. Ten supernovae (SNe) have been observed since 1917, and hence…
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…
The Magellan/IMACS Catalog of Optical Supernova Remnant Candidates in M83
William P. Blair, P. Frank Winkler, K. S. Long
We present a new optical imaging survey of supernova remnants in M83, using data obtained with the Magellan I 6.5m telescope and IMACS instrument under conditions of excellent seei…
Far Ultraviolet Spectroscopic Explorer Observations of a Supernova Remnant in the Line of Sight to HD 5980 in the Small Magellanic Cloud
Charles G. Hoopes, Kenneth R. Sembach, J. Christopher Howk +1
We report a detection of far ultraviolet absorption from the supernova remnant SNR 0057 - 7226 in the Small Magellanic Cloud (SMC). The absorption is seen in the Far Ultraviolet Sp…
HST-STIS Observations of the Cygnus Loop: Spatial Structure of a Non-radiative Shock
Ravi Sankrit, W. P. Blair, J. C. Raymond +1
We present a spatially-resolved ultraviolet spectrum of a non-radiative shock front in the Cygnus Loop, obtained with the Space Telescope Imaging Spectrograph (STIS) on board the H…
