Hadronic supercriticality in spherically expanding sources: application to GRB prompt emission
Ioulia Florou, Apostolos Mastichiadis, Maria Petropoulou
Relativistic hadronic plasmas can become under certain conditions supercritical, abruptly and efficiently releasing the energy stored in protons through photon outbursts. Past stud…
A marginally fast-cooling proton-synchrotron model for prompt GRBs
Ioulia Florou, Maria Petropoulou, Apostolos Mastichiadis
A small fraction of GRBs with available data down to soft X-rays ( keV) have been shown to feature a spectral break in the low-energy part ( keV) of their prompt…
A roadmap to hadronic supercriticalities: a comprehensive study of the parameter space for high-energy astrophysical sources
Apostolos Mastichiadis, Ioulia Florou, Elina Kefala +2
Hadronic supercriticalities are radiative instabilities that appear when large amounts of energy are stored in relativistic protons. When the proton energy density exceeds some cri…
The Onset of Hadronic Supercriticality in Expanding Sources
Ioulia Florou, Apostolos Mastichiadis
An overlooked property of hadronic models is that they can become supercritical by abruptly transforming the energy stored in the relativistic protons into radiation. Supercritical…
