See ESA/Science & Exploration/Space Science News. Calibration files for ISGRI before revolution 1626 are being produced and will be available in a few months, stay tuned. Regular Anomaly Report Meetings are taking place to define next actions with high urgency, and actions for investigation, including an inventory of all possible theoretical root causes for the ESAM trigger and de-pointing. In light, however, of the need to resolve broader programmatic and cost issues the ESA Directorate of Science Programme is facing in this and the coming 2 years, the Executive decided to postpone a proposal on the extension of the operations of Cluster, INTEGRAL and Mars Express to the next SPC meeting (#164, planned for November 2020). Made almost entirely of neutrons (subatomic particles with no electric charge), these stellar corpses concentrate more than the mass of our Sun within a sphere about 20 km in diameter. 6 July 2020  The INTEGRAL AO-18 General Programme, as recommended by the Time Allocation Committee (TAC) and approved by ESA's Director of Science (Prof. Günther Hasinger), has been released and the observers have been informed.

The XMM-Newton science teams are based in several European and US institutes, grouped into three instrument teams and the XMM-Newton Survey Science Centre (SSC). 10 January 2019  INTEGRAL and XMM-Newton have helped to find a source of powerful X-rays at the centre of an unprecedentedly bright and rapidly evolving stellar explosion that suddenly appeared in the sky earlier this year. Total number of proposals Typography: ESA Dark Red Pantone 202C. ISOC and MOC teams are on a steep learning curve gaining experience in the new way of operating INTEGRAL. Attitude sensor data showed a significant de-pointing, i.e., INTEGRAL had moved quickly away from the Sunline before re-pointing back to the expected Sun pointing direction under thruster control. The rest, about 10, are associated with anomalous X-ray pulsars, or AXPs. The operation was entirely successful and the spacecraft behaviour as predicted when planning the operation, giving more than 1 weeks time before the need to adjust the wheels speed again, marking also an important first step in demonstrating that INTEGRAL remains controllable in a predictable way. Given that up to about 21 Msec of observing time (for new observing proposals) will be available for the AO-18 observing programme (12 months duration starting on 1 January 2020), this corresponds to an oversubscription in time by a factor of 3.35. The AO-17 release will be already on 25 February, with a deadline on 5 April 2019. 14 May 2020  The deadline for the submission of proposals for AO-18 open time observations was on 4 May 2020, and all proposals are in the ISOC database. All proposals will be subject to an independent peer review by the INTEGRAL Time Allocation Committee (TAC). Print colours. Five of them are known as soft gamma repeaters, or SGRs, because they sporadically release large, short bursts (lasting about 0.1 s) of low energy (soft) gamma rays and hard X-rays. The definite integral of from to , denoted , is defined to be the signed area between and the axis, from to . Both types of integrals are tied together by the fundamental theorem of calculus. Although SGRs and AXPs were first thought to be different objects, we now know that they share many properties and that their activity is sustained by their strong magnetic fields. It is the biggest scientific satellite ever built in Europe, its telescope mirrors are amongst the most powerful ever developed in the world, and with its sensitive cameras it can see much more than any previous X-ray satellite. In principle, Mars Express, Cluster and INTEGRAL will need to prepare for an end of operations by Dec 2022. Methods: The EPIC-pn camera on-board XMM-Newton was used in the fast read-out burst mode to avoid photon pile-up, while the RGS was used in spectroscopy high count rate mode. Given that up to about 21 Msec of observing time (for new observing proposals) will be available for the AO-17 observing programme (12 months duration starting on 1 January 2020), this corresponds to an oversubscription in time by a factor of 3.5. 17 Oct 2020  On this date, 18 years ago, INTEGRAL was launched at 01:33 UTC with a Proton rocket from Baikonur, Kazakhstan. 8 July 2020  After the temporary interruption of science operations to allow for further system tests (see News Item from 23 June 2020), the return to science observations had taken place as planned in revolution 2244, starting 25 June. To understand this phenomenon, a team led by Dr Nanda Rea from the University of Amsterdam used XMM-Newton and Integral data to search for these dense electron clouds around all known magnetars, for the first time. Notice, Smithsonian Terms of Neutron stars are remnants of massive stars (10-50 times as massive as our Sun) that have collapsed on to themselves under their own weight. INTEGRAL helps unravel origin of Fast Radio Bursts. The strategy is also applied during the time that the spacecraft is within the Earth's radiation belts by selecting an optimal perigee passage attitude. Typography: ESA Red . Proposers from all over the world are welcome to participate. Science operations are managed at ESA’s European Space Astronomy Centre (ESAC), at Villanueva de la Cañada near Madrid, Spain. Aims:The galactic black hole candidate XTE J1817-330 was discovered in outburst by RXTE in January 2006.
