W. Fong, R. Margutti (Northwestern), D. Haggard (McGill) report on behalf
of a larger collaboration:
We analyzed observations of the field of the EM counterpart to LVC trigger
G298048 with the Chandra X-ray Observatory (CXO; ObsID 20728, PI Troja)
starting on 2017 Sep 1.640 UT (15.1 days after the LVC trigger time). In 50
ksec of observations, we clearly detect X-ray emission at the location of
the optical transient (Coulter et al., LVC GCN 21529
