Optical identification of the 3C 58 pulsar wind nebula (2008)

Shibanov, Yuri, Lundqvist, Natalia, Lundqvist, Peter, Sollerman, Jesper, Zyuzin, Dmitri

We have performed a deep optical imaging of 3C 58 SNR with the NOT in the B and V bands to detect the optical counterpart of the associated pulsar J0295+6449 and its torus-like wind nebula visible in...

High resolution spectroscopy of the line emission from the inner circumstellar ring of SN 1987A and its hot spots (2007)

Groeningsson, Per, Fransson, Claes, Lundqvist, Peter, Lundqvist, Natalia, Leibundgut, Bruno, Spyromilio, Jason, ...

We discuss high resolution VLT/UVES observations (FWHM ~ 6 km/s) from October 2002 (day ~5700 past explosion) of the shock interaction of SN 1987A and its circumstellar ring. A nebular analysis of...

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...
