Team of telescopes finds X-ray engine inside mysterious supernova
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. See the News item for more information.
12th INTEGRAL Conference and 1st AHEAD Gamma-ray workshop: abstract deadline extension to 5 December
28 November 2018 The abstract submission deadline for the 12th INTEGRAL Conference and 1st AHEAD Gamma-ray workshop is postponed to 5 December 2018. We invite all interested to register to the conference as soon as possible to permit an optimal organization. We hope to welcome many of you in Geneva next February.
ESA's Space Science image of the week: INTEGRAL X-rays Earth's aurora
19 November 2018 From Space in images. On 10 November 2015 was set for measuring the cosmic X-ray background using the Earth to occult the X-ray and gamma-ray sky. On that day, however, a phenomenon on Earth disturbed the observations: intense auroras dancing around the North Pole. See also ESA's news item from 2016.
INTEGRAL science operations confirmed until 31 December 2020 and indicatively extended until 31 December 2022
14 November 2018 During their recent meeting, the Science Programme Committee (SPC) approved the confirmation of science operations until 31 December 2020, as well the indicative extension of science operations for INTEGRAL until 31 December 2022, subject to a mid-term review in 2020. INTEGRAL is proven to be of great value to pursue investigations that were not foreseen at the time of its launch; this is exemplified by the role of INTEGRAL in the prompt observation and follow-up of gravitational wave detections, paving the way for the future of multi-messenger astronomy. See the full story on the SPC decision. This is excellent news for INTEGRAL and the science community. We thank you for your continuing support.
OSA 11.0 release
19 October 2018 We are very happy to share the news that today, the INTEGRAL Science Data Centre (ISDC), the INTEGRAL instrument teams, and the INTEGRAL Science Operations Centre (ISOC), have announced the release of the Offline Software Analysis version 11.0. Major improvements were made. These include the following:
- Completely new energy calibration.
- Time-dependent response files that include the redistribution and effective area.
- The instability of count rate within one revolution due to the detector polarization has been corrected.
- Time-dependent background and efficiency calibration.
- Spectra can be binned using PIL input parameters without the need for a rebinned matrix.
It is important to note that OSA 11.0 for IBIS is currently limited to data starting from 2015-12-26 (start of revolution 1626). For earlier data, the user should use OSA 10.2 with the limitations described in the user manual.
- New version of j_ima_iros with several improvements.
- Automatic search for bursts.
- Light curves now extracted with j_ima_iros.
- The use of PSD discriminator events for different energy ranges.
- Spectral extraction extended to above 400 or 600 keV (see details in user manual).
- Updated flat fields.
For any question you may have, we invite you to contact the INTEGRAL Helpdesk.
We wish you success in your analyis of INTEGRAL data.
Happy 16th birthday INTEGRAL!
17 October 2018 Sixteen years ago, on 17 October 2002 at 6:41 CEST, INTEGRAL was launched from Baikonur. Ever since it has continued to observe the gamma-ray and X-ray sky, remaining in excellent health, ready to go on for years to come.
12th INTEGRAL Conference and 1st AHEAD Gamma-ray workshop
19 September 2018 The 12th INTEGRAL Conference will be organized together with the 1st AHEAD Gamma-ray workshop on 11-15 February 2019
"I N T E G R A L l o o k s A H E A D t o M u l t i - M e s s e n g e r A s t r o p h y s i c s"
It will be hosted by the Campus Biotech, in Geneva (Switzerland). This conference will discuss recent developments in high-energy astronomy, with particular emphasis on its role in multi-messenger astronomy. Beyond the present generation of gamma-ray instruments, the choral of multi-messenger astronomies will require a voice in the MeV band. One of the aims of the workshop is therefore to review the status and development of future instruments and to discuss perspectives in observational gamma-ray astronomy. For more information consult the conference web-page https://www.astro.unige.ch/integral2019/
Registration and abstract submission are now open.
Transient IGR J17591−2342 is a new accreting millisecond X-ray pulsar14 September 2018 Using NuSTAR and NICER, an international team of astronomers has found a new accreting millisecond X-ray pulsar. The newly discovered object, designated IGR J17591−2342, is the latest addition to a still short list of known accreting millisecond X-ray pulsars. The finding is reported in a paper by Andrea Sanna et al., published August 30 on the arXiv pre-print server (arXiv:1808.10195). [From Phys.org]
INTEGRAL AO-16 General Programme approved
27 June 2018 The INTEGRAL AO-16 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.
