Swift follow-up observations of the optical transient AT2018cow/ATLAS18qqn - update
Abstract
Using the 0.9ks Swift observations (from 2018-06-19T10:34:53 to 2018-06-19T13:38:52) of the optical transient AT2018cow/ATLAS18qqn, we have fitted an absorbed power law model using wilm abundances (Wilms et al. 2000) and VERN cross-sections (Verner et al. 1996) to the X-ray spectrum and obtained the following values nh = 5.2 +/- 4.7 E20 cm2, photon index 1.6 +/- 0.1 and flux 2.6 +/- 0.3 E-11 erg/cm2/s in the 0.3-10 keV band.
