Abstract (from CDS):

Supernova (SN) 2018cow is an optical transient detected in the galaxy CGCG 137-068. It has been classified as an SN due to various characteristics in its optical spectra. The transient is also a bright X-ray source. We present results of the analysis of ∼62 ks of X-ray observations taken with the Neil Gehrels Swift Observatory over 27 d. We found a variable behaviour in the 0.3-10 keV X-ray light curve of SN 2018cow, with variability time-scales of days. The observed X-ray variability could be due to the interaction between the SN ejecta and a non-uniform circumstellar medium, perhaps related to previous mass ejections from a luminous-blue-variable-like progenitor.
