One-zone SSC model for the core emission of Centaurus A revisited
Maria Petropoulou, Eva Lefa, Stavros Dimitrakoudis +1
Aims: We investigate the role of the second synchrotron self-Compton (SSC) photon generation to the multiwavelength emission from the compact regions of sources that are characteri…
Self-consistent neutrino and UHE cosmic ray spectra from Mrk 421
Stavros Dimitrakoudis, Maria Petropoulou, Apostolos Mastichiadis
We examine the neutrino and cosmic ray spectra resulting from two models of fitting the spectral energy distribution (SED) of the blazar Mrk~421 using a self-consistent leptohadron…
Spontaneously quenched gamma-ray spectra from compact sources
Maria Petropoulou, Dafni Arfani, Apostolos Mastichiadis
We study a mechanism for producing intrinsic broken power-law gamma-ray spectra in compact sources. This is based on the principles of automatic photon quenching, according to whic…
Mrk 421 as a case study for TeV and X-ray variability in leptohadronic models
Apostolos Mastichiadis, Maria Petropoulou, Stavros Dimitrakoudis
We investigate the origin of high-energy emission in blazars within the context of the leptohadronic one-zone model. We find that -ray emission can be attributed to synchrotron…
