High angular resolution ALMA images of dust and molecules in the SN 1987A ejecta
Phil Cigan, Mikako Matsuura, Haley L. Gomez +23
We present high angular resolution (~80 mas) ALMA continuum images of the SN 1987A system, together with CO =2 1, =6 5, and SiO =5 $\!\…
The long-lived Type IIn SN 2015da: Infrared echoes and strong interaction within an extended massive shell
L. Tartaglia, A. Pastorello, J. Sollerman +41
In this paper we report the results of the first four years of spectroscopic and photometric monitoring of the Type IIn supernova SN 2015da (also known as PSN J13522411+39412…
Type Ib supernova Master OT J120451.50+265946.6: radio emitting shock with inhomogeneities crossing through a dense shell
Poonam Chandra, A. J. Nayana, Claes-Ingvar Bjornsson +4
We present radio observations of a Type Ib supernova (SN) Master OT J120451.50+265946.6. Our low frequency Giant Metrewave Radio Telescope (GMRT) data taken when the SN was in the…
Evolution of the progenitors of SNe 1993J and 2011dh revealed through late time radio and X-ray studies
Esha Kundu, Peter Lundqvist, Elena Sorokina +6
We perform hydrodynamical simulations of the interaction between supernova (SN) ejecta and circumstellar medium (CSM) for SN 1993J and SN 2011dh, and calculate the radio and X-ray…
