NuSTAR Detection of Quiescent Hard X-Ray Emission from SGR 0526-66 in the Large Magellanic Cloud
Sangwook Park, Jayant Bhalerao, Oleg Kargaltsev +1
The soft gamma-ray repeater (SGR) 0526-66 is the first-identified magnetar, and is projected within the supernova remnant N49 in the Large Magellanic Cloud. Based on our ~50 ks NuS…
An Ejecta Kinematics Study of Kepler's Supernova Remnant with High-Resolution HETG Spectroscopy
Matthew J. Millard, Jayant Bhalerao, Sangwook Park +6
We report our measurements of the bulk radial velocity from a sample of small, metal-rich ejecta knots in Kepler's Supernova Remnant (SNR). We measure the Doppler shift of the He-l…
Detailed X-Ray Mapping of the Shocked Ejecta and Circumstellar Medium in the Galactic Core-Collapse Supernova Remnant G292.0+1.8
Jayant Bhalerao, Sangwook Park, Andrew Schenck +2
G292.0+1.8 (G292) is a young (3000 yr), Galactic textbook-type core-collapse supernova remnant (CCSNR). It is characterized by X-ray, optical and infrared emission from eject…
Spatial Distribution of Mg-Rich Ejecta in LMC Supernova Remnant N49B
Sangwook Park, Jayant Bhalerao
The supernova remnant (SNR) N49B in the Large Magellanic Cloud is a peculiar example of a core-collapse SNR to show the shocked metal-rich ejecta enriched only in Mg without eviden…
X-ray ejecta kinematics of the Galactic core-collapse supernova remnant G292.0+1.8
Jayant Bhalerao, Sangwook Park, Daniel Dewey +3
We report on the results from the analysis of our 114 ks Chandra HETGS observation of the Galactic core-collapse supernova remnant G292.0+1.8. To probe the 3D structure of the clum…
