What are the responsibilities and job description for the Astrophysics: The Physics of Compact Objects position at Zintellect?
About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
A unified approach is taken in the study of the physics of compact objects (i.e., objects whose size is a few Schwarzschild radii). These objects span roughly ten decades in luminosity, from galactic x-ray sources to luminous quasars, with a variety of morphologies and global spectral characteristics (i.e., radio bright, radio quiet, blazar, and Seyfert I and II). Generally, it is thought that the engine responsible for the release of the radiation, presumably by acceretion on a compact object, is similar in all of these object classes. Their apparent differences are attributed to diverse physical conditions in their environments; however, there is no successful framework for understanding such a classification in terms of their physical parameters (e.g., magnetic field and gas density) and in relation to the energy release mechanism. Because the spectra of these objects cover a large number of decades, with roughly equal energy per decade, we have initiated a modeling program, which employs nonthermal processes. The purpose of this research is to provide model spectra that extend from radio to gamma rays, which will allow us to examine and possibly uncover correlations between the emission in diverse frequency bands. We are currently modeling radio loud quasars, placing particular emphasis on their relationship to the radio quiet counterparts.Location:
