Detecting Gamma-ray Bursts outside INTEGRAL's Field of View
Presented in a recent paper a team of astronomers led by R. Marcinkowski have shown INTEGRAL's capability to observe powerful Gamma-Ray Bursts that are located outside the telescope's field of view. The high energy radiation can pass through the lead shielding and onto the detectors. After analysis, the collected data can reveal the position on...

Powerful Emission from Anomalous X-ray Pulsars
INTEGRAL has detected surprisingly powerful X-ray and gamma ray emission from a special class of neutron star, known as Anomulous X-ray Pulsars (AXP), which proves them to be among the most magnetically active bodies known.

ESA's Integral detects closest cosmic gamma-ray burst
gamma-ray burst detected by ESA's Integral gamma-ray observatory on 3 December 2003 has been thoroughly studied for months by an armada of space and ground-based observatories. Astronomers have now concluded that this event, called GRB 031203, is the closest cosmic gamma-ray burst on record, but also the faintest. This also suggests that an entire population of sub-energetic gamma-ray bursts has so far gone unnoticed.
