Neutrinos from super-Eddington Seyfert galaxies
Lucas M. Pasquevich, Gustavo E. Romero, MatÃas M. Reynoso
Multimessenger observations suggest that Seyfert galaxies are promising sources of high-energy neutrinos, but their dense inner environments can strongly suppress the emerging very…

Neutrinos from hidden ultraluminous X-ray sources in the Galaxy
Lucas M. Pasquevich, Gustavo E. Romero, MatÃas M. Reynoso
Ultraluminous X-ray sources (ULXs) are point-like sources that exhibit apparent X-ray luminosities exceeding the Eddington limit for stellar-mass compact objects. A widely accepted…

Effects of Bethe-Heitler pair production in ultraluminous X-ray sources
Gustavo Esteban Romero, Lucas Manuel Pasquevich, Leandro Abaroa
Some black holes in X-ray binaries accrete at rates far above the Eddington limit. In this supercritical regime, photons are trapped in a radiation-dominated, geometrically thick d…
