Radius Constraints from Reflection Modeling of Cygnus X-2 with NuSTAR and NICER

Radius Constraints from Reflection Modeling of Cygnus X-2 with NuSTAR and NICER

We present a spectral analysis of NuSTAR and NICER observations of the luminous, persistently accreting neutron star (NS) low-mass X-ray binary Cygnus X-2. The data were divided into different branches that the source traces out on the Z-track of the X-ray color–color diagram; namely, the horizont...
