The X-Ray Properties of Five Galactic Supernova Remnants Detected by the Spitzer GLIMPSE Survey
Rho, Jeonghee; Heinke, Craig O.; Pannuti, Thomas G. +1 more
We present a study of the X-ray properties of five Galactic supernova remnants (SNRs)—Kes 17 (G304.6+0.1), G311.5-0.3, G346.6-0.2, CTB 37A (G348.5+0.1), and G348.5-0.0—that were detected in the infrared by Reach et al. in an analysis of data from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) that was conducted by the Spitz…
X-Ray Observations of Complex Temperature Structure in the Cool-core Cluster A85
Datta, Abhirup; Burns, Jack O.; Schenck, David E. +1 more
X-ray observations were used to examine the complex temperature structure of A85, a cool-core galaxy cluster. Temperature features can provide evidence of merging events which shock heat the intracluster gas. Temperature maps were made from both Chandra and XMM-Newton observations. The combination of a new, long-exposure XMM observation and an imp…
Multi-frequency Observations of a Superbubble in the LMC: The Case of LHA 120-N 70
Haberl, F.; Filipović, M. D.; Maggi, P. +8 more
We present a detailed study of new Australia Telescope Compact Array and XMM-Newton observations of LHA 120-N 70 (hereafter N 70), a spherically shaped object in the Large Magellanic Cloud, classified as a superbubble. Both archival and new observations were used to produce high quality radio continuum, X-ray, and optical images. The radio spectra…
HFPK 334: An Unusual Supernova Remnant in the Small Magellanic Cloud
Haberl, F.; Filipović, M. D.; Urošević, D. +5 more
We present new Australia Telescope Compact Array radio-continuum and XMM-Newton/Chandra X-ray Observatory observations of the unusual supernova remnant (SNR) HFPK 334 in the Small Magellanic Cloud (SMC). The remnant follows a shell-type morphology in the radio continuum and has a size of ~20 pc at the SMC distance. The X-ray morphology is similar;…
The Ultraviolet Attenuation Law in Backlit Spiral Galaxies
Holwerda, Benne W.; Schawinski, Kevin; Keel, William C. +2 more
The effective extinction law (attenuation behavior) in galaxies in the emitted ultraviolet (UV) regime is well known only for actively star-forming objects and combines effects of the grain properties, fine structure in the dust distribution, and relative distributions of stars and dust. We use Galaxy Evolution Explorer, XMM Optical Monitor, and H…
Diffuse X-Ray Emission from the Superbubbles N70 and N185 in the Large Magellanic Cloud
Velázquez, P. F.; Rosado, M.; Reyes-Iturbide, J. +3 more
We present a study of the diffuse X-ray emission from superbubbles (SBs) N70 (DEM L301) and N185 (DEM L25) located in the Large Magellanic Cloud, based on data from the XMM-Newton Satellite. We obtained spectra and images of these objects in the soft X-ray energy band. These X-ray spectra were fitted by a thermal plasma model, with temperatures of…
