H.E.S.S. ToO program on nearby core-collapse Supernovae: search for very-high energy $\gamma$-ray emission towards the SN candidate AT2019krl in M74

While the youngest known supernova remnants, such as Cassiopeia A, have been proven to be able to accelerate cosmic rays only up to $\sim$10$^{14}\,\mathrm{eV}$ at their present evolutionary stages, recent studies have shown that particle…

Deep observations of Kepler's SNR with H.E.S.S

Kepler's supernova remnant (SNR) which is produced by the most recent naked-eye supernova in our Galaxy is one of the best studied SNRs, but its gamma-ray detection has eluded us so far. Observations with modern imaging atmospheric…

LMC N132D: a mature supernova remnant with a youthful gamma-ray spectrum

The supernova remnant LMC N132D is a remarkably luminous gamma-ray emitter at $\sim$50 kpc with an age of $\sim$2500 years. It belongs to the small group of oxygen-rich SNRs, which includes Cassiopeia A (Cas A) and Puppis A. N132D is…
