Recently observed GRBs

Swift-XRT GRB spectrum repository

The entire UKSSDC will be offline from 0700 UT on March 5, to 1800 UT on March 8 due to work being carried out in the machine room hosting our servers. All of our services, including the website, data access and on-demand processing will be unavailable during this period. On-demand processing services will be disabled from 0000 UT on March 5. We apologise for any inconvenience caused.

This website contains a repository of Swift/XRT spectra for all GRBs which have been detected by this instrument. These spectra are suitable for scientific analysis and publication (see the usage policy). The default spectrum is a time-averaged spectrum. For some GRBs, XRT-team members may have added time-sliced spectra as well which will appear on the results pages. For more information, see the online documentation.
