2024年11月13日 · This paper presents the GRBSN webtool, a public facing application which hosts the most complete list of GRB-SN associations to date. In contrast to other repositories of supernova or gamma-ray burst data, this tool brings together all of the information required to study a GRB-SN association.

2025年3月9日 · The Fermi GBM team reports the detection of a likely LONG GRB "At 07:38:30.66 UT on 09 March 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250309B (trigger 763198715/250309318).

A one-stop shop for GRB-SN associations. E iso i s o distribution of the events. Redshift distribution of the events. The table below displays some basic parameters for the known GRB-SN associations.

The data for this event was collected from refereed papers on NASA ADS; and from online repositories including The Open Supernova Catalogue and the Swift Telescope UK Site. These graphs display observational data for this event. For help using the toolbars click here.

The trigger time listed in the Notice (ie the GRB_TIME) can be off by +/- 320 msec for events that have a trigger duration less than 64 msec. This has to do with the way that the flight software is optimized for execution speed for evaluating the shortest trigger criteria. It should be noted that even though this Notice type is called the

2025年3月10日 · Considering three typical GRB spectral models (i.e. soft, normal and hard Band functions), three timescales and the center region of GRB localization (RA= 211.07, Dec = -10.73), the 3 sigma upper limits of the potential GRB precursor energy flux (15 keV-5000 keV, in units of 10^-7 erg/s/cm^2) are reported below:

2020年8月26日 · The GBM light curve shows an exceptionally bright short GRB with a duration (T90) of about 1.14 s (50-300 keV). The time-averaged spectrum from T0-0.29 s to T0+1.76 s is best fit by a Band function with Epeak = 89.8 +/- 3.7 keV, alpha = -0.41 +/- 0.07, and beta = -2.4 +/- 0.1 The event fluence (10-1000 keV) in this time interval is (4.8 +/- 0.1 ...
