    [Auszug] Visual inspection of the X-ray intensity records of the eight Large Area Detectors (LADs) of BATSE5 showed that bursts of hard X-rays were emitted in rapid succession from a source in the general direction of the Galactic Centre beginning 1995 December 2 12:17 UT (Fig. 1). The bursts came at ...

    [Auszug] Soft γ-ray repeaters (SGRs) emit multiple, brief (∼0.1-s), intense outbursts of low-energy γ-rays. They are extremely rare—three are known in our Galaxy and one in the Large Magellanic Cloud. Two SGRs are associated with young supernova remnants (SNRs), and therefore most ...

    Notes:
    Abstract The BATSE and OSSE instrument teams have modified flight software to promptly (within 2 min of trigger) slew the OSSE detectors to burst locations determined on-board by BATSE. This enables OSSE to make sensitive searches for prompt and delayed post-burst line and continuum emission above 50 keV. In the best cases our sensitivity will be more than an order of magnitude better than any other search in this energy range. We expect to slew to 1–2 bursts per month, based on the OSSE FOV and BATSE event rate. Detections or limits from continued operation of this system may provide significant constraints on burst models. As an example of the observations made using this system, we present preliminary limits for post-burst emission from GRB 950223 on several time scales.

    Notes:
    Abstract We present preliminary results from deep optical searches of small (≤∼5 arcmin2) GRB error boxes determined using the Third Interplanetary Network (IPN3). Two of these fields also have been found to have historical OT events located within the IPN3 error boxes. We compare the preliminary results of these searches to those reported for the larger IPN1 error boxes. The small size of the IPN3 error boxes should allow a test of the hypothesis suggested by the IPN1 study that there are excess QSOs associated with the GRB fields.

    Notes:
    Abstract We describe the channel-to-energy calibration of the Spectroscopy Detectors of the Burst and Transient Source Experiment (BATSE) on the Compton Gamma Ray Observatory (GRO). These detectors consist of NaI(Tl) crystals viewed by photomultiplier tubes whose output in turn is measured by a pulse height analyzer. The calibration of these detectors has been complicated by frequent gain changes and by nonlinearities specific to the BATSE detectors. Nonlinearities in the light output from the NaI crystal and in the pulse height analyzer are shifted relative to each other by changes in the gain of the photomultiplier tube. We present the analytical model which is the basis of our calibration methodology, and outline how the empirical coefficients in this approach were determined. We also describe the complications peculiar to the Spectroscopy Detectors, and how our understanding of the detectors' operation led us to a solution to these problems.

    [Auszug] If y-ray bursters (GRBs) are at cosmological distances, the dearth of weak events results from the expansion of the universe, either because the signal is redshifted out of the bandpass of the instrument, and/or through evolution of the sources. The relative number of bursts at different ...

    Notes:
    Abstract The celestial coordinates of gamma-ray burst sources observed with BATSE on GRO are automatically determined and distributed in real time to members of the global scientific community. These data are now being used by more than 20 operations to enable searches for associated transients in a variety of other wavelength or energy regimes to identify the burst source objects. The minimum total delay time from the onset of a burst to the receipt of its coordinates by distant experimenters can be under 4 sec, less than the duration of a typical GRB, and the maximum total delay is 7 sec, or longer, depending on the distribution method. Some improvements to the BACODINE system and a summary of the follow-up observations made by some of the sites are given.

    Notes:
    Abstract The BATSE/COMPTEL/NMSU Rapid Response Network (RRN) was formed to provide rapid follow-up ofγ-ray bursts imaged by the COMPTEL instrument on the Compton Gamma-Ray Observatory. The RRN consists of ≈ 22 professional observatories located around the world spanning both northern and southern hemispheres. Also included in the RRN is the Airforce GEODSS network. The goal of the RRN is to perform optical and radio observations of COMPTEL error boxes as soon after the burst as possible. We present results from the first two years of operation of this network.
