The broad-lined Type-Ic supernova SN 2022xxf with extraordinary two-humped light curves
H. Kuncarayakti, J. Sollerman, L. Izzo +60
We report on our study of supernova (SN) 2022xxf based on observations obtained during the first four months of its evolution. The light curves (LCs) display two humps of similar m…
The luminous red nova variety: AT 2020hat and AT 2020kog
A. Pastorello, G. Valerin, M. Fraser +32
We present the results of our monitoring campaigns of the luminous red novae (LRNe) AT 2020hat in NGC 5068 and AT 2020kog in NGC 6106. The two objects were imaged (and detected) be…
Supernovae 2016bdu and 2005gl, and their link with SN 2009ip-like transients: another piece of the puzzle
A. Pastorello, C. S. Kochanek, M. Fraser +52
Supernova (SN) 2016bdu is an unusual transient resembling SN 2009ip. SN 2009ip-like events are characterized by a long-lasting phase of erratic variability which ends with two lumi…
The outer rings of SN1987A
A. Tziamtzis, P. Lundqvist, P. Groningsson +1
We used low resolution spectroscopy from VLT/FORS1, and high resolution spectra from VLT/UVES, to estimate the physical conditions in the ORs, using nebular analysis for emission l…
Observational and theoretical constraints for an H-halo around the Crab Nebula
A. Tziamtzis, M. Schirmer, P. Lundqvist +1
We searched for a fast moving H shell around the Crab nebula. Such a shell could account for this supernova remnant's missing mass, and carry enough kinetic energy to make SN 10…
