But none of the emissions most commonly identified in comets, such as hydroxyl or cyanogen, show up in the UVOT spectrum.
Early Swift UVOT observations show no ultraviolet enhancement.
When the UVOT is fully operational, both the XRT and UVOT will provide an in-depth observation of the gamma-ray burst and its afterglow.
This composite of three Swift UVOT ultraviolet images highlights the luminous hot gas in the supernova remnant.
When we aren't studying GRBs, we use the satellite's unique capabilities to engage in other scientific investigations, some of which produce beautiful images from the UVOT that we're delighted to be able to share with the public," Michael Siegel, lead scientist on the UVOT and a research associate in astronomy and astrophysics at the MOC, said.
According to Massimiliano De Pasquale, a GRB scientist of the UVOT team from MSSL, "The UVOT instrument is particularly suited to study bursts with an average to high redshift - a part of the ultraviolet spectrum that is difficult for even the very big ground-based telescopes to study.
Using UVOT with Swift, we can now find redshifts for bursts that were difficult to capture in the past and find out more about their distant host galaxies, about ten billion light years away," he added.
