Abstract
This work explores whether hadronic processes could be responsible for the high-energy emission seen in quasars identified by the Large Area Telescope (LAT) instrument aboard the Fermi satellite. In contrast to purely leptonic models, the work investigates whether hadronic mechanisms can explain the observed gamma-ray spectra by analyzing the spectral energy distributions (SEDs) of a chosen sample of FSRQs (Flat Spectrum Radio Quasars). By incorporating both hadronic and leptonic components into their multi-wavelength modeling, we evaluate the model's feasibility to simultaneously describe the data collected by Fermi-LAT and neutrinos detected by IceCube. According to the results, a hadronic contribution would be required to explain the SED of quasars detected by Fermi-LAT. However, their contribution to the neutrino flux detected by IceCube remains understated.
Resumen
Este trabajo explora si los procesos hadrónicos podrían ser responsables de la emisión de alta energía observada en los cuásares identificados por el instrumento Large Area Telescope (LAT) a bordo del Satélite Fermi. En contraste con los modelos puramente leptónicos, el trabajo investiga si los mecanismos hadrónicos pueden explicar los espectros de rayos gamma observados, analizando las distribuciones espectrales de energía (SEDs) de una muestra escogida de FSRQs (Flat Spectrum Radio Quasars). Al incorporar componentes hadrónicos y leptónicos en su modelización multi-longitud de onda, evaluamos la viabilidad del modelo para describir simultáneamente los datos recogidos por Fermi-LAT y los neutrinos detectados por IceCube. Según los resultados, sería necesaria una contribución hadrónica para explicar la SED de los cuásares detectados por Fermi-LAT. Sin embargo, su contribución al flujo de neutrinos detectado por IceCube sigue siendo subestimada.References
