Ejecta, Dust, and Synchrotron Radiation in B0540-69.3: A More Crab-Like Remnant than the Crab
Brian J. Williams, Kazimierz J. Borkowski, Stephen P. Reynolds +10
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…
The Chandra ACIS Survey of M33 (ChASeM33): Investigating the Hot Ionized Medium in NGC604
R. Tuellmann, T. J. Gaetz, P. P. Plucinsky +7
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 interac…
The Heating of Thermal Electrons in Fast Collisionless Shocks: The Integral Role of Cosmic Rays
Cara E. Rakowski, J. Martin Laming, Parviz Ghavamian
Understanding the heating of electrons to quasi-thermal energies at collisionless shocks has broad implications for plasma astrophysics. It directly impacts the interpretation of X…
The Chandra ACIS Survey of M33 (ChASeM33): Transient X-ray Sources Discovered in M33
Benjamin F. Williams, Terrance J. Gaetz, Frank Haberl +7
The Chandra ACIS Survey of M33 (ChASeM33) has acquired 7 fields of ACIS data covering M33 with 200 ks of exposure in each field. A catalog from the first 10 months of data, along w…
A Half-Megasecond Chandra Observation of the Oxygen-Rich Supernova Remnant G292.0+1.8
Sangwook Park, John P. Hughes, Patrick O. Slane +3
We report on our initial analysis of a deep 510 ks observation of the Galactic oxygen-rich supernova remnant (SNR) G292.0+1.8 with the {\it Chandra X-ray Observatory}. Our new {\it…
Chandra ACIS Survey of M33 (ChASeM33): A First Look
Paul P. Plucinsky, Benjamin Williams, Knox S. Long +22
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\ar…
