X-Ray Observations of Type Ia Supernova 2018cqj

Abstract

I report on Chandra X-ray observations of SN 2018cqj, a low luminosity Type Ia supernova that showed an H$\alpha$ line in its optical spectrum. No X-ray emission was detected at the location of the SN, with an upper limit to the X-ray luminosity of 2 $\times 10^{39}$ erg s${}^{-1}$.
