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...
The Chandra ACIS Survey of M33 (ChASeM33): Investigating the Hot Ionized Medium in NGC604 (2008)
Tuellmann, R., Gaetz, T. J., Plucinsky, P. P., Long, K. L., Hughes, J. P., Blair, W. P., ...
NGC604 is the largest HII-region in M33, second only within the Local Group to 30 Dor, and is important as a laboratory for understanding how massive young stellar clusters interact with the...
Chandra ACIS survey of M33 (ChASeM33): a first look (2008)
Plucinsky, Paul P., Williams, Benjamin, Long, Knox S., Gaetz, Terrance J., Sasaki, Manami, Pietsch, Wolfgang, ...
Chandra ACIS Survey of M33 (ChASeM33): A First Look (2007)
Plucinsky, Paul P., Williams, Benjamin, Long, Knox S., Gaetz, Terrance J., Sasaki, Manami, Pietsch, Wolfgang, ...
We present an overview of the Chandra ACIS Survey of M33 (ChASeM33): A Deep Survey of the Nearest Face-on Spiral Galaxy. The 1.4 Ms survey covers the galaxy out to $R \approx 18\arcmin (\approx 4$...
Gaetz, Terrance J., Blair, William P., Hughes, John P., Winkler, P. Frank, Long, Knox S., Pannuti, Thomas G., ...
We present and interpret new X-ray data for M33SNR21, the brightest X-ray supernova remnant (SNR) in M33. The SNR is in seen projection against (and appears to be interacting with) the bright HII...
Direct Measurement of Neutron-Star Recoil in the Oxygen-Rich Supernova Remnant Puppis A (2006)
Winkler, P. Frank, Petre, Robert
A sequence of three Chandra X-ray Observatory High Resolution Camera images taken over a span of five years reveals arc-second-scale displacement of RX J0822-4300, the stellar remnant (presumably a...
Probing Multiple Sight Lines through the SN 1006 Remnant by UV Absorption Spectroscopy (2006)
Winkler, P. Frank, Long, Knox S., Hamilton, Andrew J. S., Fesen, Robert A.
Absorption-line spectroscopy is an effective probe for cold ejecta within an SNR, provided that suitable background UV sources can be identified. For the SN 1006 remnant we have identified four such...
Dust Destruction in Type Ia Supernova Remnants in the Large Magellanic Cloud (2006)
Borkowski, Kazimierz J., Williams, Brian J., Reynolds, Stephen P., Blair, William P., Ghavamian, Parviz, Sankrit, Ravi, ...
We present first results from an extensive survey of Magellanic Clouds supernova remnants (SNRs) with the Spitzer Space Telescope. We describe IRAC and MIPS imaging observations at 3.6, 4.5, 5.8, 8,...
Far-flung Filaments of Ejecta in the Young Supernova Remnant G292.0+1.8 (2005)
Winkler, P. Frank, Long, Knox S.
New optical images of the young SNR G292.0+1.8, obtained from the 0.9-m telescope at CTIO, show a more extensive network of filaments than had been known previously. Filaments emitting in [O III] are...
Winkler, P. Frank, Gupta, Gaurav, Long, Knox S.
