Balmer filaments in Tycho's supernova remnant: an interplay between cosmic-ray and broad-neutral precursors
Sladjana Knežević, Ronald Läsker, Glenn van de Ven +8
We present H spectroscopic observations and detailed modelling of the Balmer filaments in the supernova remnant Tycho. We used Galaxy H Fabry-Pérot Spectrometer on the Willia…
Balmer-dominated shocks in Tycho's SNR: omnipresence of CRs
Sladjana Knežević, Ronald Läsker, Glenn van de Ven +8
We present wide-field, spatially and highly resolved spectroscopic observations of Balmer filaments in the northeastern rim of Tycho's supernova remnant in order to investigate the…
Three-dimensional distribution of ejecta in Supernova 1987A at 10 000 days
J. Larsson, C. Fransson, J. Spyromilio +19
Due to its proximity, SN 1987A offers a unique opportunity to directly observe the geometry of a stellar explosion as it unfolds. Here we present spectral and imaging observations…
The Destruction of the Circumstellar Ring of SN 1987A
Claes Fransson, Josefin Larsson, Katia Migotto +23
We present imaging and spectroscopic observations with HST and VLT of the ring of SN 1987A from 1994 to 2014. After an almost exponential increase of the shocked emission from the…
An Integral View of Balmer-dominated Shocks in Supernova Remnants
Sladjana Nikolić, Glenn van de Ven, Kevin Heng +5
We present integral-field spectroscopic observations with the VIMOS-IFU at the VLT of fast (2000-3000 km/s) Balmer-dominated shocks surrounding the northwestern rim of the remnant…
An Integral View of Fast Shocks around Supernova 1006
Sladjana Nikolić, Glenn van de Ven, Kevin Heng +5
Supernova remnants are among the most spectacular examples of astrophysical pistons in our cosmic neighborhood. The gas expelled by the supernova explosion is launched with velocit…
