Measuring Black Hole Spins: ToO Observations of a Black Hole Transient
Abstract
We propose two 20 ksec long Target of Opportunity observations of a bright black hole transient in outburst, to study the relativistic Fe Kα line profile and its variability in such systems, and to perform X-ray timing studies. Fe lines probe the innermost regions of accretion disks where the gravitational field is the most intense. To obtain a maximum signal to noise ratio in the line, these observations will be using the modified timing mode of the EPIC-pn cameras, recently employed successfully in observations of the relativistic line of Cygnus X-1. The accurate measurement of the line shape will then lead to constraints on the black hole spin.
