SN 1994W: An Interacting Supernova or Two Interacting Shells?
Luc Dessart, D. John Hillier, Suvi Gezari +2
We present a multi-epoch quantitative spectroscopic analysis of the Type IIn SN 1994W, an event interpreted by Chugai et al. as stemming from the interaction between the ejecta of…
Probing Shock Breakout with Serendipitous GALEX Detections of Two SNLS Type II-P Supernovae
Suvi Gezari, Luc Dessart, Stephane Basa +13
We report the serendipitous detection by GALEX of fast (<1 day) rising (>1 mag) UV emission from two Type II plateau (II-P) supernovae (SNe) at z=0.185 and 0.324 discovered by the…
The IRT Telescope on board the THESEUS mission
Diego Gotz, Aline Meuris, Eric Doumayrou +28
We present the Infra-Red Telescope (IRT), which is part of the payload of the THESEUS mission, one on the three phase A candidate missions for the M7 slot of ESA (launch date 2037)…
The Chinese-French SVOM mission for GRBs studies
Jacques Paul, Jianyan Wei, Stephane Basa +1
We present the SVOM (Space-based multi-band astronomical Variable Objects Monitor) mission that the Chinese National Space Agency and the French Space Agency have decided to jointl…
The type Ia supernova SNLS-03D3bb from a super-Chandrasekhar-mass white dwarf star
D. Andrew Howell, Mark Sullivan, Peter E. Nugent +14
The acceleration of the expansion of the universe, and the need for Dark Energy, were inferred from the observations of Type Ia supernovae (SNe Ia). There is consensus that SNe Ia…
GRB 240715A: Revealing Novel Intrinsic Mechanism by Different Individual Pulse
Wen-Jun Tan, Chen-Wei Wang, Shao-Lin Xiong +37
The Space-based multiband astronomical Variable Objects Monitor (SVOM), detected its first short gamma-ray burst, GRB 240715A, in-flight, which was jointly observed by Fermi. Based…
Neutrino alert systems for Gamma Ray Bursts and Transient astronomical Sources
Stephane Basa, Damien Dornic, Gabrielle Lelaizant +3
GRBs are the most energetic events in the Universe, associated with the death of massive stars (core-collapse supernovae) or the merging of neutron stars or black holes. Discovered…
