The Spin and Orientation of the Black Hole in XTE J1908+094

NuSTAR observed the black hole candidate XTE J1908+094 during its 2013 and 2019 outbursts. We use relativistic reflection to measure spin of through 19 different assumptions relxill flavors parameter combinations. The most favored model in terms Deviance Information Criterion (DIC) measures be , inclination degrees (1σ statistical errors). look at effects coronal geometry density accretion disk on prediction. All tested models provide consistent estimates. discuss evolution measurement techniques using X-ray binaries implications this reconciling distributions stellar-mass measurements made gravitational wave observations.
