Kavli Affiliate: Erin Kara | First 5 Authors: Ole König, Guglielmo Mastroserio, Thomas Dauser, Mariano Méndez, Jingyi Wang | Summary: The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies ${<}1$ keV across all states. The hard state power spectrum can be decomposed into […]
