INTEGRAL Latest News
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.
Giorgio Palumbo: 1939 - 2018
INTEGRAL has lost another great Mission Scientist on 19 June 2018
26 June 2018 Giorgio Palumbo was born in 1939 in Turin, where he graduated in Physics. After obtaining a PhD at the University of Calgary (Canada), he was first researcher of the National Research Council, then became associate professor, and subsequently an ordinary professor, at the Department of Astronomy of the University of Bologna. He was director of the Department from 2006 to 2009.
He was certainly one of the main protagonists of high-energy astrophysics in the international scene. In his research, presented in over 300 articles on Physics and Astrophysics, he dealt with cosmic radiation, cosmic rays, supernovae, galaxies and groups of galaxies, active galactic nuclei, astrochemistry. He devoted a lot of his efforts to teaching (with numerous dozens of undergraduates and doctoral students) and to the dissemination of astronomy through conferences, writings and columns on the monthly and television programs of RAI Educational.
Selected on 31 May 1995 by the European Space Agency (ESA) as INTEGRAL Mission Scientist, he was one of the drivers of the scientific success of the mission, and to which he made a fundamental contribution for almost 20 years. In 2014 he resigned for family reasons.
In the early 2000s he was a member of the ESA Astronomy Working Group. He subsequently obtained numerous posts in advisory committees.
He collaborated for a long time with the Italian Space Agency, ASI, and in particular from 1997 to 2002 as coordinator of the activity connected to the Science of the Universe.
"We learn about the death of Giorgio Palumbo, a scientist and man of great culture, and an authoritative reference in our community" says Nichi D'Amico, president of INAF. "I had the privilege and the pleasure of knowing him during the years spent in Bologna and I want to remind everyone of one of his jokes. With his sly and affable air, he told me that it was enough for him to see how a young person moves, how s/he walks, to perceive their talent. It was true: Giorgio was a great breeder of talents and we owe him the growth of entire lines of research, authoritative and prestigious. To the family, friends and colleagues, a warm embrace".
