INTEGRAL Latest News
INTEGRAL AO-14 General Programme approved
28 June 2016 The INTEGRAL AO-14 General Programme, as recommended by the Time Allocation Committee (TAC) and approved by ESA's Director of Science (Prof. Alvaro Giménez), has been released and the observers have been informed.
11th INTEGRAL Conference, Gamma-ray astrophysics in multi-wavelength perspective
23 June 2016 The INTEGRAL 2016 Conference is organized by SRON Netherlands Institute for Space Research and the Astronomical Institute "Anton Pannekoek" of the University of Amsterdam, and will take place on October 10-14, 2016, in Amsterdam, The Netherlands. The focus of the meeting is on the astrophysics of highly energetic phenomena that are observed with INTEGRAL, taking into account advanced modelling and observational constraints from all wavelengths and other cosmic messengers. The INTEGRAL 2016 conference is open for registration and abstract submission, see: www.sron.nl/integral2016-registration. The deadline for abstracts is July 1.
JEM-X2 without Science data for a week
06 June 2016 On 27 May (10:36Z), JEM-X2 started to lose science data on the highspeed line connecting front-end and data processing electronics. The problem was resolved on 3 June (06:29Z) after a reset of the instrument. This covers the time from science window 39 in revolution 1683 to science window 14 in revolution 1686. JEM-X1 and all other instruments operated normally.
INTEGRAL TOO observations of MAXI J0911-655
21 April 2016 MAXI J0911-655 (aka Swift J0911.9-6452) is a new X-ray transient first detected on February 2016 at a position compatible with the globular cluster NGC 2808 (Atel #8872, 8884). INTEGRAL TOO observations in revolution 1671 (2016-04-23 23:43:40 to 2016-04-25 06:51:22) are being undertaken in coordination with XMM-Newton.
14th Announcement of Opportunity (AO-14): preliminary statistics
14 April 2016 The deadline for the submission of proposals for AO-14 open time observations was on 8 April 2016, and all proposals are in the ISOC database. Below are some preliminary statistics on the proposals that have been received.
Total number of proposals
The total number of proposals received is 57. The total observing time requested is about 115 Msec (for all types of observation, i.e., fixed time, normal time, and ToO). Here, 10% of the requested total ToO time has been taken into account. Given that up to about 21 Msec of observing time (for new observing proposals) will be available for the AO-14 observing programme (12 months duration starting on 1 January 2017), this corresponds to an oversubscription in time by a factor of 5.5.
The non-ToO proposals are requesting data rights for 359 sources in total. 12 proposals requested coordinated time with NuSTAR, Swift and/or XMM-Newton.
Proposals per category
In the following table we give the breakdown of number of proposals as a function of the proposal category. Note that the numbers on requested observing times do include ToO proposals, but it has been assumed here, that a typical ToO proposal requests about 10% of its total observing time as entered into PGT from all the candidate sources included in a ToO proposal.
|Scientific Category||Number of proposals|| Requested observing time (Ms) |
includes ToO times x 10%
| Nucleosynthesis and diffuse |
In mid May, the Time Allocation Committee will peer review all proposals and recommend the AO-14 observing programme to ESA.
INTEGRAL sets limits to gamma rays from merging black holes
30 March 2016 Following the discovery of gravitational waves from the merging of two black holes, INTEGRAL has revealed no simultaneous gamma rays, just as models predict. See the ESA press release.
INTEGRAL instruments shut off over Easter
29 March 2016 On Saturday 26 February a Single Event Upset on one of the Payload Module Power Distribution Units resulted in all instruments being suddenly switched off. The Flight Control Team at ESOC has been working hard and the instruments are being activated again one after the other.
