Swift-XRT Monitoring of Fermi-LAT Sources of Interest

The monitoring data shown on this site provides near real-time results from Swift observations of Fermi-LAT "sources of interest" and flaring sources. While this list is dominated by blazars, some X-ray binaries and Galactic transients are also included. The preliminary results on this page are intended to provide rapid feedback to the scientific community to aid in target of opportunity planning, multiwavelength campaigns, and planning of interesting scientific publications.

Data on this site is available to the public (thanks to support from the Fermi GI program and the Swift Team). If you make use of any of these data, we ask that you reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949 and that you notify Abe Falcone and Michael Stroh at monitoring@swift.psu.edu.

The results presented on this page are from a preliminary analysis of the Swift-XRT data. The analysis procedure is described in this README file. Since the analysis is performed using automated scripts and the results are not always reviewed by human eyes, we recommend that these data be reviewed by hand before use in publications.

For questions or requests for more detailed analysis, please contact Abe Falcone and Michael Stroh at monitoring@swift.psu.edu. This web site is under construction so please report any web site related problems to the email address listed above.

Upcoming Observations

Upcoming Observations

In order to encourage multiwavelength observations of these sources and foster coordination with others interested in Swift observations of these sources, we provide a list of tentative scheduling dates for our approved ToO programs. Most of the targets listed below are part of the original 23 Fermi-LAT Sources of Interest but some additional sources of interest may also appear.

These windows are tentative and may change due to orbital constraints or high priority programs such as GRBs or other ToOs. There may be additional observing programs for these sources from other groups that are not listed.

No observations are currently scheduled for this source through our monitoring program, but there may be other ToO programs that have upcoming observations on this source.
