Gamma-ray burst locations from the Burst and Transient Source Experiment

open access: closedAIP Conference Proceedings, 1991
The Burst and Transient Source Experiment (BATSE) consists of eight anisotropic γ‐ray spectrometers at the corners of the Compton Gamma Ray Observatory. BATSE monitors the full sky from a fixed orientation and determines the direction of γ‐ray bursts with an accuracy appropriate for studying the bursts’ celestial distribution.

Radio Observations of Transient Gamma Ray Sources with the Westerbork Array

open access: closed, 1994
Two γ-ray bursts have been rapidly imaged by COMPTEL (within ~ 6 hours of their occurrence) and their error boxes searched by Westerbork for evidence of a fading counterpart at radio wavelengths. These searches have revealed no likely candidate counterparts to the bursts.

Variable and transient Galactic gamma-ray sources with AGILE

Il Nuovo Cimento C, 2011
AGILE has been providing continous monitoring of the Galactic plane in its three years of operation. Thanks to its sensitivity at energies near 100 MeV, AGILE has observed variability and transient behaviour in a number of sources. Simultaneous hard-X ray coverage, rapid alerts to the astronomical community, and multiwavelength campaigns have provided ...

Location of Transient Gamma-Ray Sources with Thin Flat Scintillators

IEEE Transactions on Nuclear Science, 1976
Thin flat slabs of scintillator are a useful means of measuring angular location of gamma-ray fluxes of astronomical interest. A statistical estimate of position error has been made of two scintillator systems suitable for gamma-ray burst location from a balloon or satellite platform.

The burst and transient source experiment for the gamma-ray observatory

AIP Conference Proceedings, 1982
The Burst and Transient Source Experiment (BATSE) is a highly sensitive, all‐sky monitor for the Gamma‐Ray Observatory (GRO). The eight scintillation detector modules of BATSE are positioned around the GRO spacecraft provide a uniform view of the entire sky above the horizon. Each module is 20 in. in diameter, 0.5 in.

Estimating significance in observations of variable and transient gamma-ray sources

Astroparticle Physics, 2017
Abstract The standard method for estimating the statistical significance of a gamma-ray source detection is that introduced by Li & Ma (1983), Eq. (17). In observing sources with time-dependent light curves, one can improve on this method by including approximate a priori knowledge of the source temporal behavior.

A Light and Effective Wide Field Monitor for Gamma Ray Bursts and Transient Sources

AIP Conference Proceedings, 2009
We present here a concept for a light and low‐power wide field monitor working in the X‐ray range, suitable for simultaneous imaging of large portions of the sky and GRB localizations. Our concept evolves from and improves on the design of the 5‐kg SuperAGILE experiment, flying on the AGILE mission and currently delivering arcmin‐localizations of GRBs ...

Observation of AGILE transient $$\gamma $$-ray sources in coincidence with cosmic neutrino events

Rendiconti Lincei. Scienze Fisiche e Naturali, 2019
The origin of the diffuse flux of very high-energy cosmic neutrinos above TeV energies observed by the IceCube experiment at the South Pole is still largely unknown. Simultaneous multi-frequency observations of the uncertainty location regions of these cosmic neutrinos are needed to identify the possible electromagnetic counterpart.

Performance Of The Large-Area Detectors For The Burst And Transient Source Experiment (BATSE) On The Gamma Ray Observatory

SPIE Proceedings, 1989
BATSE, one of four experiments on the Gamma Ray Observatory (GRO), is expected to provide the most sensitive observations of gamma-ray bursts yet obtained, as well as to provide long-term monitoring of hard X-ray and low-energy gamma-ray emission from bright pulsating sources, transients, and solar flares.

A concept for a lightweight, low-power and sensitive Silicon-based All Sky Monitor for transient sources and Gamma Ray Bursts

AIP Conference Proceedings, 2010
We present a concept for a coded‐mask All Sky Monitor based on Silicon Drift Detectors. The current design has a high level of readiness, minimizes the total weight ( 2 steradians and an on‐axis sensitivity of ∼3 mCrab (5σ, 50 ks). The intrinsic modularity of the detector allows to envisage experiments with different configurations, in terms of field ...
