In additional to gamma-ray bursts, I am also interested in other sources/transients in the hard X-ray sky.



Monitoring the sky in hard X-ray
The 157-Month Swift-BAT Hard X-ray Survey
The Neil Gehrels Swift Observatory has been monitoring the hard X-ray sky (14-195 keV) for ~ 15 years and has detected over 1600 sources, including AGNs, X-ray binaries, stars, galaxy clusters, pulsars, supernova remnant...etc. Following previous Swift/BAT Hard X-ray Survey Catalogs (Oh et al. 2018; Baumgartner et al. 2013; Tueller et al. 2009; Markwardt et al. 2005), we are working on the next catalog, which conisists of 157 month of Swift/BAT data. A quick look of the 157-month light curves of sources presented in the 105 month catalog is available here .
