Ejecta, Dust, and Synchrotron Radiation in B0540-69.3: A More Crab-Like Remnant than the Crab (2008)
Williams, Brian J., Borkowski, Kazimierz J., Reynolds, Stephen P., Raymond, John C., Long, Knox S., Morse, Jon A., ...
We present near and mid-infrared observations of the pulsar-wind nebula (PWN) B0540-69.3 and its associated supernova remnant made with the {\it Spitzer Space Telescope}. We report detections of the...
FUV and X-ray Observations of the Reverse Shock in the SMC SNR 1E 0102.2-7219 (2006)
Sasaki, Manami, Gaetz, Terrance J., Blair, William B., Edgar, Richard J., Morse, Jon A., Plucinsky, Paul P., ...
We present FUSE and XMM-Newton data for the reverse shock of the O-rich SNR 1E0102.2-7219 in the SMC. The FUSE observations cover three regions with significantly different optical [O III]...
Finkelstein, Steven L., Morse, Jon A., Green, James C., Linsky, Jeffrey L., Shull, J. Michael, Snow, Theodore P., ...
We present new optical emission-line images of the young SNR 1E 0102-7219 (E0102) in the SMC obtained with the HST Advanced Camera for Surveys (ACS). E0102 is a member of the oxygen-rich class of...
The reverse shock of SNR1987A at 18 years after outburst (2005)
Smith, Nathan, Zhekov, Svetozar A., Heng, Kevin, McCray, Richard, Morse, Jon A., Gladders, Mike
We use low-dispersion spectra obtained at the Magellan Observatory to study the broad H-alpha emission from the reverse shock of the infant supernova remnant SNR1987A. These spectra demonstrate that...
The [O III] Veil: Astropause of Eta Carinae's Wind? (2005)
Smith, Nathan, Morse, Jon A., Bally, John
We present narrowband images of eta Carinae in the light of [O III] 5007 obtained with HST/WFPC2, as well as a ground-based image in the same emission line with a larger field of view. These images...
A Million-Second Chandra View of Cassiopeia A (2004)
Hwang, Una, Laming, J. Martin, Badenes, Carles, Berendse, Fred, Blondin, John, Cioffi, Denis, ...
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW counterpart) is clearly...
The Purple Haze of Eta Carinae: Binary-Induced Variability? (2004)
Smith, Nathan, Morse, Jon A., Collins, Nicholas R., Gull, Theodore R.
Asymmetric variability in ultraviolet images of the Homunculus obtained with the Advanced Camera for Surveys/High Resolution Camera on the Hubble Space Telescope suggests that Eta Carinae is indeed a...
We present optical spectra of the ionized `Outer Ejecta' of Eta Carinae that reveal differences in chemical composition at various positions. In particular, young condensations just outside the dusty...
Kinematics and Ultraviolet to Infrared Morphology of the Inner Homunculus of η Carinae (2004)
Smith, Nathan, Morse, Jon A., Gull, Theodore R., Hillier, D. John, Gehrz, Robert D., Walborn, Nolan R., ...
We present the first ultraviolet and optical images of η Car and itscircumstellar Homunculus nebula, obtained with the Advanced Camera forSurveys/High Resolution Camera (ACS/HRC) on board the Hubble...
Deconstructing HD 28867 (2002)
Walter, Frederick M., Beck, Tracy L., Morse, Jon A., Wolk, Scott J.
The 3" pair of B9 stars, HD 28867, is one of the brightest X-ray sources in the Taurus-Auriga star forming region. In this multi-wavelength study, we attempt to deduce the source of the X-ray...
Hubble Space Telescope WFPC-2 Imaging of Cassiopeia A (2001)
Fesen, Robert A., Morse, Jon A., Chevalier, Roger A., Borkowski, Kazimierz J., Gerardy, Christopher L., Lawrence, Stephen S., ...
The young SNR Cassiopeia A was imaged with WFPC-2 through four filters selected to capture the complete velocity range of the remnant's main shell in several important emission lines. Primary lines...
NGC 7582: The Prototype Narrow-Line X-ray Galaxy (1998)
Schachter, Jonathan F., Fiore, Fabrizio, Elvis, Martin, Mathur, Smita, Wilson, Andrew S., Morse, Jon A., ...
NGC 7582 is a candidate prototype of the Narrow Line X-ray Galaxies (NLXGs) found in deep X-ray surveys. An ASCA observation shows the hard (> 3 keV) X-ray continuum of NGC 7582 drops 40% in ~6 ks,...
