description: There is an ongoing debate about the origin of the 511 keV electron-positron signal: Many unresolved point sources or truly diffuse emission in the interstellar medium. A smooth distribution of sub-threshold sources has been suggested in two alternative scenarios: Bisnovatyi-Kogan et al. (2017) focused on the cumulative effect of intermittently flaring stars producing a 511 keV line through the same processes as in the Sun. Coronal mass ejections carry accelerated particles that eventually produce positrons through decays which subsequently annihilate in the solar atmosphere. Bartels et al. (2018) proposed the idea of accreting compact objects in quiescence that steadily eject sub-relativistic pair-plasma which may also be related to the unresolved GeV Galactic centre excess.Both studies suggest that their models could be readily tested through the observation of globular clusters (GCs) at 511 keV. In both cases the predicted 511 keV flux from individual GCs is too low for SPI to be detectable however the whole Milky Way population of 157 GCs is estimated to add up to 10% of the diffuse flux. The relative 511 keV fluxes from GCs would then allow to distinguish between models providing a smoking-gun evidence for the true origin of Galactic positrons.Most GCs are located in the same regions where the diffuse 511 keV flux from bulge and disk is also strong so that individual point sources will not outshine the diffuse emission. For this reason we proposed and were granted long-term SPI observations in AO18 and AO19 to target a region that includes GCs which would show a high contrast against the diffuse emission. In AO20 we wish to continue these observations to reach our goal of quadrupling the exposure time in the chosen region within three years. Based on detailed modelling to predict the 511 keV emission in GCs we found two neighbouring and (still) underexposed spots in the sky we wish to observe in four  [truncated!

description: We propose INTEGRAL observations of flaring blazars triggeredby the AGILE gamma-ray satellite. For the first time after CGROit will be possible to observe blazars during high gamma-rayactivity states from a few keV up to a few GeV. This chance willbe crucial to study the simultaneous spectral and temporal behaviourof blazars and to study the synchrotron to inverse Compton (IC)transition region. The gamma-ray (E >100 MeV) flaring duration (few days)is prolonged enough to allow INTEGRAL re-pointing. Quasi-simultaneous observations by INTEGRAL and AGILE of blazars in activestates will be important to establish the IC peak of the nu-Fnuspectra and to study the spectral break in the hard X-ray medium gamma-rayenergy band. We request 300 ksec  INTEGRAL ToO observations for each of the first 3 major flares detected by AGILE. A similar proposal (Prop. ID 0420063 P.I. S. Vercellone) was approved with Grade-A as part of INTEGRAL AO-4 but not perfomed because of the AGILE launch delay. [truncated! Please see actual data for full text]

description: As part of a large multi-wavelength campaign IXPE will observe the enigmatic X-ray binary Cyg X-3 between October 31 and November 6. A previous observing campaign earlier this month brought very surprising results regarding the X-ray polarization of this target and thus preparations for another comprehensive observing campaign is underway.We propose that INTEGRAL will join this effort providing unique coverage in the hard X-band as NuSTAR will be observing Cyg X-3 during this second observing run for only a small fraction of that period. Previous experience with IXPE has shown that complementary broad band multiwavelength coverage is crucially important to decompose the polarization data when multiple spectral components contribute to the IXPE band as is the case here.Two exposures of 100 ks (5x5 pattern) during INTEGRAL revolutions 2567 and 2568 would allow us to measure the shape of the high-energy spectrum and the intensity of the Compton hump during the campaign (Swift/BAT indicates 130 mCrab fluxes) while simultaneous NICERmonitoring will keep a close track of the iron line region and the 1-10 keV continuum shape.

description: MAXI J1305-704 is a new X-ray transient recently discovered by MAXI (ATel #4024 #4035). On April 10 the Swift/BAT flux was ~25 mCrab (15-50 keV  ATel #4034). Since then it rose up to ~50 mCrab and it isnow seen at a plateau at ~30 mCrab. A Swift/XRT spectrum on April 11 could be described by either a power-law with photon index ~2 or an absorbed thermal disk model with kT~1.2 keV.  The large optical amplitude the blue optical SED and the initial hard X-ray spectrum point to a black hole being the compact object (ATel #4030). A hard-to-soft state transition occurred on April 9/10 alsosuggestive of a black hole (ATel #4044).  The non-detection of strong X-ray variability on April 11 supports the current soft-state interpretation.  However as noted in ATels #4035 and 4044 a neutron star can still not be ruled out. Swift/XRT observations on April 14 also revealed absorption dips possibly at a period of ~1.5 hours which would be the shorterst orbital period seen so far for a black hole candidate. In order to verify the nature of the compact object we request 2 TOO observations of 50 ksec each to be executed asap.  These observations provide the high energy coverage (IBIS  and  SPI) to allow the detection of a potential hard energy tail. The long uninterrupted observations allow us to verify with JEM-X the presence of X-ray dips  if observed they will help in scrutinizing the orbital period.  The long observation will also maximize the chance to detect any type I X-ray burst which would rule out a black hole but point to a neutron star. We therefore request the observations to be done in the HEX pattern. We are aware that INTEGRAL TOO proposals do exist in the AO9 proposal database. However these are for objects for which the compact object nature has been established.  Since it is uncertain at the moment they cannot be triggered. As waiting to get a firm answer on that could be too late we suggest to observe  [truncated! Please see actual data for full text]

NICER detected an X-ray brightening event from Eta Car starting on Nov 15 2019 (ATEL 13327) and now AGILE reports a brightening at energies > 100 MeV (ATEL 13329). A connection between the X-ray and gamma-ray variations of the source has not been seen before and needs to be studied with INTEGRAL.  [truncated! Please see actual data for full text]

description: We propose to observe the microquasar GRS 1758258 in the next of its rare dim soft states as a ToOobservation for 170 ksec combined with a contemporaneous 3 ks observation by Swift. The obtained broadband spectrum will be the first of its kind obtained during one of the peculiar soft states of GRS 1758258.Comparing it to the accumulated broad band spectrum of the hard state will reveal any changes of the accretiondisk and Comptonization parameters from the state change and also possibly reveal the hard tail induced bythe state transition. Knowing these changes will help us to understand what causes black holes to switchbetween non-thermal radio-loud and thermal radio-quiet states. Observing the soft state of the persistent sourceGRS 1758258 is especially interesting as it is most likely a low mass X-ray binary and thus belongs to a classof objects that usually display transient behavior.

description: The survey of the Galactic Plane has continued as one of the main INTEGRAL scientific objectives because of the scientific potential of both new source discovery and detailed monitoring of already known sources that will provide a legacy archive and a basis for future missions. We propose for a total of 2Ms of observation in AO20 to continue our previous approved Key Program covering areas of the Plane with regular scans every orbit. For this AO we selected again the section of the Plane incorporating two sky regions centred at l=+/-30 that are both rich in galactic sources (LMXB and HMXB SFXT in particular) and potential MeV/TeV sources. In view of the new z-flip mission strategy our priority is still this but we are flexible to extend the program along the Plane as during the AO18/AO19. Our purpose is to regularly monitor known systems as well as to dramatically enhance the chances of discovering new systems or new outbursts from known sources. This program will allow a rapid response to bright events and a detailed study of faint transients and their long-term activity. Such a programme will be of high value to a very large fraction of the high-energy astronomy community stimulating science immediately and furthermore contributing greatly to the INTEGRAL legacy.In order to maximise the engagement of the scientific community we will continue to make the observations public immediately. The team will make as it has done through AO8-19 the scw-resolution IBIS and JEM-X light curves (in two energy bands) and per-revolution mosaic images publicly available through the web as soon as possible. Any interesting source behaviour that emerges from our observations will be announced promptly in the usual way through Atels1 so that rapid follow-up by the community is possible as has already been demonstrated.

description: We propose to monitor NGC 4151 with INTEGRAL to accurately and simultaneously measure the spectral shape up to above 200 keV and to study large amplitude variations with an unprecedented sensitivity and time coverage at high energy. We will correlate the high energy spectral cutoff with other continuum parameters to confirm thermal comptonisation and determine the main physical mechanism driving the variability. We will also disentangle the reflection hump and its variations from the primary continuum and intrinsic absorption and correlate those with the narrow iron line variability to determine the nature of the thick reprocessing medium and the geometry of cold matter surrounding the source. We will finally probe for the existence of a hard non thermal tail which will constrain the electrons acceleration mechanisms. We request 4 observations of 400 ksec each. [truncated!

description: The Galactic bulge region is a rich host of variable X-ray and gamma-ray point sources.In AO-3 AO-4 AO-5 and AO-6 we have been monitoring this region with one hexagonal pattern approximately every 3 days whenever it was visible by INTEGRAL. Due to the high scientific return and to preserve the continuity with respect to past observations of this ever-changing region we suggest to continue our successful observing program. Because of the new format of AO-7 and as a service to the scientific community we ask the observations to be made public immediately. Moreover we make the IBIS/ISGRI and JEM-X light curves both in two energy bands perscience window and per hexagonal observation as well as the mosaic images per hexagonal pattern publicly available through the web as soon as possible after the observations have been performed. Any interesting source behaviour which emerges from our observations will be announced promptly so that rapid follow-up by the community is possible. Our team consists of scientists with expertise on a large range of topics. We also intend to do a more in-depth analysis (spectra bursts flares etc.) of sources of particular interest on short and long time scales. These sources include bright and relatively faint X-raytransients X-ray bursters persistent neutron star and black-hole candidate binarieshigh-mass X-ray binaries etc.. [truncated!

description: The Orion region hosts one of the most nearby regions of recent massive-star formation. COMPTELs measurement of 1809 keV emission from this region shows an interesting offset of the 26Al emission source from its likely sources and appears rather extended. This suggests that radioactivity is displaced from its sources into the Eridanus cavity. If true this opens unique possibilities to study the ISM near massive stars and the interaction of massive stars with their surroundings in a new way: Due to the proximity and location at the edge of a large cavity we can compare locations of massive stars to the morphology of the ISM and the emission pattern of 26Al radioactivity in order to constrain 26Al ejection in mass and velocity from massive stars. We aim to confirm and clarify the intensity and location of this nearby 26Al source with INTEGRAL. Furthermore with these observations we can check for annihilation radiation and for the intensity of nuclear deexcitation gamma-rays in the MeV range both valuable diagnostics of the structure of superbubble interiors. It is important for INTEGRAL to assess the scientific potential of Orion region observations now  this will give us the option to eventually obtain unique measurements of ISM dynamics and massive stars as its driving engines within INTEGRALs lifetime there is hardly a more suitable and closeby target region.

Located 2.8 kpc away it is a well-established persistent Z-source and one of the few neutron star binaries where extended radio jets have been resolved at milliarcseconds scales. We propose to observe Sco X-1 with INTEGRAL for 215 ks and with XMM-Newton  for 80ks to obtain a (quasi-)continuous broad-band coverage of the target fully overlapping with a 72-hr continuous Global VLBI radio monitoring observation. We aim to unveil the link between specific accretion events (state transitions and/or quasi-periodic oscillations) and the launch of transient outflows and providing new insights into ultra-relativistic outflows from neutron stars and the conditions underlying their production.

description: We propose a dedicated INTEGRAL monitoring program of the ultra-compact X-ray binary and micro-quasar 4U0614+091 to study its emission properties in hard X-rays. This source is situated in a region of the sky well outside theGalactic bulge and is thus one of the low-mass X-ray binaries being least observed by INTEGRAL. However 4U0614+091 is an interesting target for several reasons: not only it harbours the closest active X-ray burster it exhibitsvariations at very different time scales and over the whole electromagnetic spectrum such as synchrotron jet emissionX-ray flaring states and thermonuclear X-ray bursts. Moreover the high energy persistent emission from the source ischaracterised by a particularly hard (non thermal) X-ray tail. Therefore we want to exploit the INTEGRAL instrumentationto survey the dynamical behaviour of the source and better describe its spectrum in hard X-rays. The monitoringcampaign we propose (for a total of 500 ks exposure) has been approved for AO-9 but have not yet been performed. Itwill indeed make it possible to follow the evolution of the long term persistent emission variability as well as toinvestigate the activity of shorter time scale processes. In fact 4U 0614+091 is also known for having exhibited usualshort X-ray bursts an hours-long superburst and several intermediately long bursts with superexpansion of the neutronstars photosphere. The proposed observing strategy will for instance allow us to relate the bursting behaviour of thesource to its broadband emission and especially to its flaring activity on time scales of days to weeks.The present proposal does also request joint XMM and INTEGRAL observations.

description: We ask for INTEGRAL TOO observations of one blazar in outburst in AO-10 for up to 600 ks conditional to stringent triggering criteria based on X-ray brightening as detected by the current high energy missions including INTEGRAL itself Swift MAXI and NuSTAR. Coordinated INTEGRAL and multiwavelength observations will guarantee the coverage of a broad energy range and allow us to follow the evolution of the overall spectral energy distribution (SED) during one or more flaring episodes. We will thus measure accurately the high energy spectrum and monitor the hard X-ray light curve and thus constrain the time-dependent parameters of the emission models. In past INTEGRAL AOs we have triggered similar observations as part of multi wavelength campaigns and have demonstrated that for bright X-ray sources (> 20 mCrab) IBIS can map the interday hard X-ray variability.
