About this award
This is a $74,999.92 research grant awarded to the University of Maryland, Baltimore County (UMBC) by the National Aeronautics and Space Administration (NASA) for a project related to modeling the gamma-ray emission from blazars, a type of active galactic nucleus. The proposed work aims to address a long-standing issue in the field by exploring the effects of moving the blazar emission location beyond the parsec-scale external photon fields and modeling it as synchrotron-self Compton of first and second order. The grant will also investigate the idea that the blazar sequence can be explained by varying a single parameter, the relativistic electron power injected in the jet. UMBC is a public research university that is part of the University System of Maryland, which has a broad portfolio of federal contract and grant awards supporting research, education, and other initiatives across multiple agencies, including NASA. This grant does not have a set-aside designation.
Description
In a seminal paper, sikora, begelman, and rees (1994) argued that the gamma-RAY emission from blazars is due to external compton scattering of nuclear broad-line photons. This model quickly became a paradigm in the field, though a long-standing issue is its inability to explain the anomalously high amplitude of gamma-RAY flares compared to lower energies. Here we propose to show that moving the blazar emission location out beyond the parsec-scale external photon fields and modeling IT as synchrotron-self compton of first and second order solves many observational issues, including the high-amplitude variability. In this framework, we will also explore the idea that the blazar sequence can be explained by varying a single parameter, the relativistic electron power injected in the jet.
