Supernova Remnant 1987A: High Resolution Images and Spectrum from Chandra Observations
Sangwook Park, Svetozar A. Zhekov, David N. Burrows +3
We report on the morphological and spectral evolution of SNR 1987A from the monitoring observations with the Chandra/ACIS. As of 2005, the X-ray-bright lobes are continuously brigh…
The reverse shock of SNR1987A at 18 years after outburst
Nathan Smith, Svetozar A. Zhekov, Kevin Heng +3
We use low-dispersion spectra obtained at the Magellan Observatory to study the broad H-alpha emission from the reverse shock of the infant supernova remnant SNR1987A. These spectr…
Limits from the Hubble Space Telescope on a Point Source in SN 1987A
G. J. M. Graves, P. M. Challis, R. A. Chevalier +16
We observed supernova 1987A (SN 1987A) with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST) in 1999 September, and again with the Advanced Camer…
Photoionized Lines in the X-ray Spectra of SMC X-1
S. D. Vrtilek, J. C. Raymond, B. S. Boroson +1
We present a detailed spectral analysis of Chandra/ACIS-S CC mode observations of the massive X-ray binary system SMC X-1. The system was observed during both the high and low X-ra…
