A comprehensive study of GRB 070125, a most energetic gamma ray burst (2008)
Chandra, Poonam, Cenko, S. Bradley, Frail, Dale, Chevalier, Roger, Macquart, Jean-Pierre, Kulkarni, Shri, ...
We present a comprehensive multiwavelength analysis of the bright, long duration gamma-ray burst GRB 070125, comprised of observations in $\gamma$-ray, X-ray, optical, millimeter and centimeter...
Seeking for the progenitors of type Ia supernovae (2008)
Patat, Ferdinando, Chandra, Poonam, Chevalier, Roger, Justham, Stephen, Podsiadlowski, Philipp, Wolf, Christian, ...
Hughes, John P., Chugai, Nikolai, Chevalier, Roger, Lundqvist, Peter, Schlegel, Eric
We set sensitive upper limits to the X-ray emission of four Type Ia supernovae (SNe Ia) using the Chandra X-ray Observatory. SN 2002bo, a normal, although reddened, nearby SN Ia, was observed 9.3...
Constraints on type Ib/c supernovae and gamma-ray burst progenitors (2007)
Fryer, Chris L., Mazzali, Paolo A., Prochaska, Jason, Cappellaro, Enrico, Panaitescu, Alin, Berger, Edo, ...
Coronal emission from the shocked circumstellar ring of SN 1987A (2006)
Groeningsson, Per, Fransson, Claes, Lundqvist, Peter, Nymark, Tanja, Lundqvist, Natalia, Chevalier, Roger, ...
High resolution spectra with UVES/VLT of SN 1987A from December 2000 until November 2005 show a number of high ionization lines from gas with velocities of roughly 350 km/s, emerging from the shocked...
HST Spectroscopy of Spot 1 on the Circumstellar Ring of SN 1987A (2000)
Michael, Eli, McCray, Richard, Pun, C. S. J., Garnavich, Peter, Challis, Peter, Kirshner, Robert P., ...
We present ultraviolet and optical spectra of the first bright spot (PA = 29 degrees) on Supernova 1987A's equatorial circumstellar ring taken with the Space Telescope Imaging Spectrograph. We...
New HST Observations of High Velocity Lyman Alpha and Balmer Alpha in SNR 1987A (1998)
Michael, Eli, McCray, Richard, Pun, C. S. J., Borkowski, Kazimierz, Garnavich, Peter, Challis, Peter, ...
We describe and model high velocity (~15,000 km/s) Lyman alpha and Balmer alpha emission from supernova remnant 1987A seen in September and October 1997 with the Space Telescope Imaging Spectrograph....
