Detection of hard X-ray emission from Nova Sgr 2012 with Swift
Abstract
We observed Nova Sgr 2012 (PNV J17452791-2305213) with the Swift satellite on 2012 May 10, 40 days after the discovery of this nova. The total exposure time with the XRT instrument was 6280 s. In contrast to the non-detections reported in ATels #4061 and #4088, Swift/XRT clearly detected X-ray emission from the nova on 2012 May 10.
A total of 249 source counts were detected within a circular region with a radius of 20 pixels centered on the position of the nova, resulting in a 0.3-10 keV count rate of 0.039 c/s.- Publication:
