INTEGRAL Conference postponed (again) to fall 2021

17 May 2021 The next INTEGRAL Conference, INTEGRAL: towards the third decade of X and Gamma ray observations, will now take place in October 2021, either in the week 11-16 or 17-22. The organizers have tentatively scheduled a hybrid conference with the in-presence part to be held in Sardinia and a broadcasted part via Zoom. However, due to the travel restriction unknowns, organizers are not in the conditions to confirm the in-presence part at the moment. Further details will be communicated as soon as feasible.

19th Announcement of Opportunity (AO-19): Preliminary submission statistics

19 April 2021  The deadline for the submission of proposals for AO-19 open time observations was on 9 April 2021, 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 49. The total observing time requested is about 58 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-18 observing programme (12 months duration starting on 1 January 2021), this corresponds to an oversubscription in time by a factor of 2.8.

The non-ToO proposals are requesting data rights for 311 sources in total. 11 proposals requested joint 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%
Galactic Astronomy 25 43
Extragalactic Astronomy 15 7
Nucleosynthesis and diffuse
continuum/line emission
9 8
Total 49 58

 

Mid-May the Time Allocation Committee will peer review all proposals and recommend the AO-19 observing programme to ESA.

INTEGRAL AO-19 CALL FOR OBSERVING PROPOSALS IS OPEN!

1 March 2021  Today, the ESA Director of Science (Prof. Guenther Hasinger) released the 19th Announcement of Opportunity (AO-19) for observing proposals with INTEGRAL.

This announcement solicits proposals for observations to be carried out from January 2022 for a period of 12 months. Proposers from all over the world are welcome to participate. All proposals will be subject to an independent peer review by the INTEGRAL Time Allocation Committee (TAC). The deadline for proposal submission is Friday 9 April 2021, 14:00 CEST.

More information can be found on the AO-19 page.

INTEGRAL: unravelling the mysteries of the X- and gamma-ray sky

27 January 2021  The INTEGRAL Project Scientist discussed with the Innovation News Network, some of the current and future INTEGRAL mission’s activities, including studying flashes of powerful radiation that suddenly appear in the gamma-ray sky. The interview has been published in the online journal "The Innovation Platform Issue 4".

A gamma-ray burst from a magnetar in a nearby galaxy

15 January 2021  A mysterious gamma-ray burst that swept past the Earth on 15 April 2020, likely came from a magnetar in the nearby galaxy NGC 253. INTEGRAL helped establish the source of the burst. This finding confirms the long-held suspicions that some GRBs are in fact powerful flares from relatively close magnetars. See the NASA press release.

ISOC AO-18 observations underway and preparations for AO-19

4 January 2021 ISOC wishes you a healthy and successful 2021. The AO-18 cycle of observations started on January 1st and will last 12 months, see the INTEGRAL target lists and sky maps for details as well as the Long-Term Plan.

ISOC is preparing the next call for proposals requesting INTEGRAL observing time. The AO-19 release will be already on 1 March, with a deadline on 9 April 2021. The AO-19 cycle of observations is foreseen to begin on 1 January 2022 and has the usual duration of 12 months.

Release of AO-19: call for observing time proposals: 1 March 2021
Deadline for submission of observing time proposals: 9 April 2021 (14:00 CEST)
Meeting of the Time Allocation Committee: 18-20 May 2021
Start of AO-19 cycle of observations: 1 January 2022
