Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open question in astrophysics. Studies of SN host galaxies have proven to be …
Some observations suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as supernovae as do several models. Establishing a causal connection between these mass-loss episodes and the final explosion would …
The pursuit of the progenitors of short duration-hard spectrum gamma-ray bursts (SHBs) draws strongly upon similar quests for the origin of supernovae (SNe) and long duration-soft spectrum GRBs (LSBs). Indeed the notion that, in the absence of …
