Cassiopeia A is a well-studied supernova remnant and one of the youngest remnants in the Milky Way with the supernova occurring in the late 1600s. First infrared (IR) echoes (Krause et al. 2005) and then scattered light echoes of Cas A were found (Rest 2008), which revealed that the supernova was a type IIb (Krause et al. 2008). Further analysis of the IR echoes showed that the EUV-UV...
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in Type IIn systems due to their dense, interaction-dominated circumstellar environments. We present a comprehensive photometric analysis of SN$\,$2019vxm, a long-duration, luminous Type IIn supernova,...
Supernovae that interact with nearby circumstellar material shed by the progenitor shortly before the terminal explosion shed light on the late lives of massive stars. These objects are highly heterogeneous, with early observations shedding light on even more diversity. We present SN2025ngs, a nearby interacting supernova in NGC5961. SN2025ngs has a spectroscopic evolution almost mimicking...
