NICER observation list: Target ID 767701

Abstract

The blazar Mrk 501 features a relativistic jet that accelerates particles, potentially to TeV energies, displaying rapid flux variability on minute timescales in X-ray and gamma-ray bands. However, the mechanisms responsible for this particle acceleration remain poorly understood. Recent advancements, including NICER's high-resolution spectral monitoring and the launch of IXPE, which measures X-ray emission polarization, have enabled us to probe the jet's magnetic field geometry and its impact on acceleration processes. Our proposal involves continuous monitoring of Mrk 501 during Cycle 6 using 3 ks exposures. This initiative aims to investigate changes in its spectral state and determine their duty cycle.
