Optical identification of the 3C 58 pulsar wind nebula
Yuri Shibanov, Natalia Lundqvist, Peter Lundqvist +2
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 win…

High resolution spectroscopy of the line emission from the inner circumstellar ring of SN 1987A and its hot spots
Per Groeningsson, Claes Fransson, Peter Lundqvist +8
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 neb…

Coronal emission from the shocked circumstellar ring of SN 1987A
Per Groeningsson, Claes Fransson, Peter Lundqvist +5
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, emergi…
