“…Furthermore, Sakamoto et al (2008) studies the potential confusion between the simple PL, CPL, and Band function (Band et al 1993) spectral fit in the BAT observations using simulated spectra. These authors found that most of the BATdetected GRBs probably have E peak within the BAT energy range, and derived an equation to estimate E peak (for the Band function) using the photon index from the simple PL fit.…”

To date, the Burst Alert Telescope (BAT) onboard Swift has detected ∼1000 gamma-ray bursts (GRBs), of which ∼360 GRBs have redshift measurements, ranging from z=0.03 to z=9.38. We present the analyses of the BATdetected GRBs for the past ∼11 years up through GRB151027B. We report summaries of both the temporal and spectral analyses of the GRB characteristics using event data (i.e., data for each photon within approximately 250 s before and 950 s after the BAT trigger time), and discuss the instrumental sensitivity and selection effects of GRB detections. We also explore the GRB properties with redshift when possible. The result summaries and data products are available at http://swift.gsfc.nasa.gov/results/batgrbcat/index.html. In addition, we perform searches for GRB emissions before or after the event data using the BAT survey data. We estimate the false detection rate to be only one false detection in this sample. There are 15 ultra-long GRBs (∼2% of the BAT GRBs) in this search with confirmed emission beyond ∼1000 s of event data, and only two GRBs (GRB100316D and GRB101024A) with detections in the survey data prior to the starting of event data.

“…The prompt emission spectra of SN-GRBs which have reported broad-band spectral parameters are well fitted with the Band function (Band et al 1993). To compare the best fit parameters of the Band function between the SN-GRBs and typical long GRBs, the histograms of the low-energy photon index, α, the high-energy photon index, β, and the spectral peak energy, E peak , of the long GRBs are shown in Figure 4.…”

Abstract. I present the observational properties of the prompt emission of supernova associated GRBs (SN-GRBs) focusing on temporal and spectral characteristics. I compare the properties of SN-GRBs with typical long GRBs to see whether there is a distinct difference or not. Furthermore, I present our attempt to search for hard X-ray emission prior to the discovery date from optically identified type Ibc supernovae using Swift BAT survey data.

“…In principle, extragalactic bursts could arise from sources other than GRBs, but given the broad range of spectral and temporal behavior exhibited by GRBs, we use the term uGRB to denote our whole extragalactic population of bursters. Their spectra are well fit with a Band function (Band et al 1993) or power law with an exponential cut-off function that is typical of GRBs. Parameters from the spectral fits using the Band function were typically not well constrained and are not reported.…”

The Fermi Gamma-ray Burst Monitor (GBM) is an all-sky gamma-ray monitor well known in the gamma-ray burst (GRB) community. Although GBM excels in detecting the hard, bright extragalactic GRBs, its sensitivity above 8 keV and its all-sky view make it an excellent instrument for the detection of rare, short-lived Galactic transients. In 2010 March, we initiated a systematic search for transients using GBM data. We conclude this phase of the search by presenting a three-year catalog of 1084 X-ray bursts. Using spectral analysis, location, and spatial distributions we classified the 1084 events into 752 thermonuclear X-ray bursts, 267 transient events from accretion flares and X-ray pulses, and 65 untriggered gamma-ray bursts. All thermonuclear bursts have peak blackbody temperatures broadly consistent with photospheric radius expansion (PRE) bursts. We find an average rate of 1.4 PRE bursts per day, integrated over all Galactic bursters within about 10 kpc. These include 33 and 10 bursts from the ultra-compact X-ray binaries 4U0614+09 and 2S0918-549, respectively. We discuss these recurrence times and estimate the total mass ejected by PRE bursts in our Galaxy.
