X-ray Observations of the Bipolar PNe NGC 2346 and NGC 7026
Robert A. Gruendl, Martin A. Guerrero, You-Hua Chu +1
We have obtained X-ray observations of the bipolar planetary nebulae (PNe) NGC 2346 and NGC 7026 with XMM-Newton. These observations detected diffuse X-ray emission from NGC 7026 b…
An Optical Study of Stellar and Interstellar Environments of Seven Luminous and Ultraluminous X-Ray Sources
Caitlin J. Ramsey, Rosa M. Williams, Robert A. Gruendl +3
We have studied the stellar and interstellar environments of two luminous X-ray sources and five ultraluminous X-ray sources (ULXs) in order to gain insight into their nature. Arch…
XMM-Newton Spectra of Intermediate-Mass Black Hole Candidates: Application of a Monte-Carlo Simulated Model
Q. Daniel Wang, Yangsen Yao, Wakako Fukui +2
We present a systematic spectral analysis of six ultraluminous X-ray sources (NGC1313 X-1/X-2, IC342 X-1, HoIX X-1, NGC5408 X-1 and NGC3628 X-1) observed with XMM-Newton Observator…
Supernova Remnant Crossing a Density Jump: A Thin Shell Model
Yang Chen, Fan Zhang, Rosa M. Williams +1
The environments of supernova explosion are often inhomogeneous and there may be jumps in their density structure. We have developed a semi-analytic model under the thin-shell appr…
X-Ray Emission from Multi-Phase Shock in the Large Magellanic Cloud Supernova Remnant N49
Sangwook Park, David N. Burrows, Gordon P. Garmire +3
The supernova remnant (SNR) N49 in the Large Magellanic Cloud has been observed with the Advanced CCD Imaging Spectrometer (ACIS) on board the {\it Chandra X-Ray Observatory}. The…
