Nucleosynthesis in The Oxygen-Rich Supernova Remnant G292.0+1.8 from Chandra X-Ray Spectroscopy
Sangwook Park, John P. Hughes, Patrick O. Slane +4
We continue our analysis of the Galactic oxygen-rich supernova remnant (SNR) G292.0+1.8, which was observed with the {\it Chandra X-ray Observatory}. The high angular resolution {\…
Characteristics of Diffuse X-Ray Line Emission within 20 pc of the Galactic Center
Sangwook Park, Michael P. Muno, Frederick K. Baganoff +5
Over the last 3 yrs, the Galactic center (GC) region has been monitored with the Chandra X-Ray Observatory. With 11 Chandra observations through 2002 June, the total effective expo…
Monitoring The Evolution of SNR 1987A with Chandra
Sangwook Park, David N. Burrows, Gordon P. Garmire +2
We report on the results of our monitoring program of SNR 1987A with the Chandra X-Ray Observatory. The high resolution images and the spectra from the latest Chandra data suggest…
Detection of Magnesium-Rich Ejecta in the Middle-Aged Supernova Remnant N49B
Sangwook Park, John P. Hughes, Patrick O. Slane +4
The middle-aged supernova remnant (SNR) N49B in the Large Magellanic Cloud has been observed with the {\it Chandra X-Ray Observatory}. The superb angular resolution of {\it Chandra…
An X-Ray Pulsar in the Oxygen-Rich Supernova Remnant G292.0+1.8
John P. Hughes, Patrick O. Slane, Sangwook Park +2
We report the discovery of pulsed X-ray emission from the compact object CXOU J112439.1-591620 within the supernova remnant (SNR) G292.0+1.8 using the High Resolution Camera on the…
