Measuring the Spin and Inclination of the Black Hole Transient MAXI 1820+070 using NICER and NuSTAR spectra
Abstract
The bright X-ray transient MAXI1820+0870 was observed many times with NICER and NuSTAR during its outburst in 2018. We present the results of joint fits to the X-ray spectra made in both hard and soft states and the transitions between them, using high density REFLIONX and KERRBB models where relevant. Best-fit values of spin, inclination and coronal properties will be discussed.
