Stellar core-collapses provide formidable conditions to probe new physics. Supernovae as one possible outcome of these events are driven by the transport of energy through neutrinos. In this talk I will present the result of numerical simulations in axial symmetry show how nonstandard neutrino interactions can lead to imprints in the gravitational wave signal of supernovae.
The origin of tiny neutrino masses remains an open question in particle physics, prompting extensions beyond the Standard Model (SM). In this talk, I will present a study of a $U(1)$ gauge extension of the SM that incorporates three generations of Majorana-type right-handed neutrinos. This framework leads to the emergence of a neutral beyond-the-Standard-Model (BSM) gauge boson, denoted as...
Neutrinos experience collective flavor conversion in extreme astrophysical environments such as core-collapse supernovae (CCSNe). One manifestation of collective conversion is slow flavor conversion (SFC), which has recently attracted renewed interest owing to its ubiquity across different regions of the supernova environment.
In this study, we systematically examine the evolution of...
Largerly due to the spectral degeneracy in high-energy observations, the composition of black hole jets, wheter lepton-dominated or baryon-loaded, remains a longstanding open question. We propose that extreme mass ratio (EMR) black hole binaries, particularly systems involving a secondary microquasar interacting periodically with the accretion flow of a primary supermassive black hole, can...
