description: Fast Radio Bursts (FRBs) have already provided a large wealth of interest and speculation about their origin complemented by a large number of applications for new science that can be explored once we have a statistically significant sample of them. FRBs show an impulsive behaviour characterised by a $sim$ms-long very energetic burst. A growing subset of the population is now characterised by repeating bursts. The chance to observe FRBs more than once has helped constrain their properties and shaped the proposed models for their origin. The identification of its host galaxy has allowed in-depth studies of the original repeater: FRB 121102. Amongst the new repeaters FRB 180916.J0158+65 has the lowest projected dispersion measure and was most recently localised to a nearby massive spiral galaxy. Its high activity led most recently to the discovery of a 5-day activity cycle of the source every $sim 16$ days. With its closeness its localisation and now its periodicity FRB 180916.J0158+65 represents the most promising candidate for investigating the properties of repeaters which have so far been elusive in the case of FRB 121102. One outstanding question concerns the multi-wavelength emission from FRBs which are at present only seen in the radio band. Higher energy bursts are predicted by most FRB models either simultaneously with the radio bursts or as an afterglow after the bursts. We propose INTEGRAL observations combined to a capillary international multi-wavelength campaign led by the Sardinia Radio Telescope with the aim of detecting for the first time this source at hard X-rays and collecting unprecedented observational information about the broadband emission properties of the source and in turn discriminating its nature.

description: This Crab offset staring observation is used to determine the off-axis imaging properties of IBIS and to provide an absolute calibration of  the off-axis PSF.  The off-axis position of the Crab in this staring observation (zenith 9.6 degree azimuth 270. degree)  is defined in the instrumental coordinate system and depends on the start date of the observation.

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 immediate scientific returns and act as a base for future missions. We propose for a total of 3.0 Ms of observations in AO16 and 3 Ms in AO17 to continue our Key Program covering areas of the Plane with regular scans every orbit. For these AOs we have selected two sections of the Plane incorporating regions centered at l=+30 and l=-30 that are rich in galactic sources (LMXB and HMXB SFXT in particular) and potential MeV/TeV sources.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 transients. 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 proposal team will provide as they have through AO8-15 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 Atels so that rapid follow-up by the community is possible as has been already demonstrated.

title: 2040006

description: We propose to observe either a new or a known black-hole transient for 680 ks (about 4 INTEGRAL orbits) when thesource is showing a bright hard state (above 200 mCrab). Our main goals are: to detect the soft gamma-ray tail observed in the spectra above 200 keV (mainly with SPI) to measure a SED from radio to gamma-rays using the multi-wavelength observations that we will trigger to follow the high-energy cutoff variation of hard X-ray spectral component (mainly with IBIS). The above will allow us to improve our understanding of the accretion-ejection connection in black-hole transients. The INTEGRAL TAC approved this proposal for the last AO19. However the observations have been not triggered yet due to the lack of a suitable target. [truncated! Please see actual data for full text]

description: One of the most important results on Galactic black holes that has come out of INTEGRAL was the discovery of the signature of strong polarization of the >300 keV spectrum of Cygnus X-1. This discovery is an indication that this spectral component is due to synchrotron emission probably from the radio jet that is present in the hard state. In this two year 2 Ms program we propose a continuation of these measurements with the aim of detecting changes in the hard state polarization properties. [truncated!

description: This observation targets SN2011fe which occurred on 23 August 2011 in the nearby galaxy M101 at 6.4 Mpc distance aiming at high energy emission from 56Co decay gamma-ray lines and its associated Compton-scattered continuum. The prospected emission maximum from the 56Co lines should be ~early November. These ToO observations target the rise of such emission towards this maximum which is expected to show characteristic differences for different progenitor and explosion models. Observations are in standard dither mode for broader usage of these public data andcomplement another proprietary ToO on SN2011fe as was proposed for AO-8 and is scheduled in the first weeks after explosion and at expected gamma-ray maximum.

description: We ask for the continuation of our two year INTEGRAL Key Programme to observe the area of the Galaxy bounded by 20  l  +20 and 15  b  +15 with a total of 2 Msec of observations per AO.  The aim is to study the inner region of the Galaxy namely to continue the search for evidence for gamma-ray flares from Sgr A including following potential brightness changes after the expected impact of a cloud in fall 2013/spring 2014 to continue measuring the flux evolution of Sgr B2 through 2014 to monitor bursts and flares from the many LMXB neutron star sources and to enable significant serendipitous science in the Galactic center region. We do not ask for data rights for any of the sources except for the Galactic Center but will put in seperate data rights proposals on individual sources. [truncated!

title: 0220123

description: We propose 260 ks of INTEGRAL time to perform a ToO observation of a transient millisecond X-ray pulsar in outburst. The target can be either one of the five known transient accreting millisecond X-ray pulsars in the case of a new outburst or a newly observed object of this class. Since these sources are a new class of astronomical objects INTEGRAL observations will give a fundamental contribution providing a sufficiently detailed spectrum at energies higher than 20 keV. In particular we will be able to study the energy spectrum of these sources which is usually observed to be quite hard even in outburst in a broad band energy range and with unprecedented high sensitivity above 20 keV which  will allow us to disentangle the contribution of soft reflection and hard spectral components.The INTEGRAL observation will also allow to perform a timing analysis in an interesting and yet unexplored energy range.

description: Massive stars and their impacts on their surrounding interstellar medium comprise the feedback scenario which is one of the main astrophysical issues in the context of galaxy and cosmic chemical evolution. Radioactivity from 26Al adds a unique diagnostic tool for studying this scenario in nearby massive-star regions. The Orion region hosts one of the closest such regions at ~400 pc. COMPTELs measurement of 1809 keV emission from this region had shown an interesting offset of the 26Al emission from its likely sources and emission appears rather extended. This suggests champagne-like outflow into the Eridanus cavity as has recently also been seen with XMM-Newton. If true this opens unique possibilities to study the ISM as it is shaped by massive stars and the interaction of massive stars with their surrounding ISM in a new way: Due to their proximity and location on the near side of molecular clouds and at the edge of a large cavity we can compare the locations of massive stars to the morphology of the ISM and the emission pattern of 26Al radioactivity in order to constrain 26Al ejection from massive stars in mass and velocity. Previous observations led to ~3 Ms of exposure resulting in a tantalizing hint of the expected signal. With our proposed deepening of exposure (3 Ms in AO-10) we aim to measure the intensity (from AO-10) and kinematics (later from more AO-11 observations) of this nearby 26Al source with INTEGRAL. We aim at unique data for ISM dynamics and massive stars as its driving engines within INTEGRALs lifetime  there is hardly a more suitable and closer target region. These observations also support search 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  moreover over 30 Fermi sources can be studied within our target region.

description: After 15 years from the first observed outburst the NS-LMXB Transient XTE J1701-462 turned on again on September 6 (Iwakiri et al. 2022 ATel 15592). The MAXI light curve indicates that it is likely to reach the peak in luminosity within a week and its luminosity is approaching 500mCrab in the 2-10 keV band.Among its class XTE J1701-462 is a unique target: it is the only known NS to exhibit (Lin et al. 2009) all the NS-LMXB spectral substates from Cyg X-2-like Z class up to Sco X-1-like Z and back down to bright atoll and island atoll states during its 2006 outburst evolution. We request INTEGRAL observations of XTE J1701-462 coordinated with the approved IXPE TOO programme foreseen on Sept. 29 and Oct. 9 2022. [truncated! Please see actual data for full text]

description: Fast radio bursts (FRBs) are bright and very short flashes of radio waves. They form a new class of astrophysical transients whose origins are currently a mystery. Among the several dozen FRBs discovered today FRB121102 is the only one showing a repeating activity and identified at sub-arcsec precision on the sky. Its bursts appear clustered in time with a cyclic activity several weeks long hence allowing multi-wavelength follow-up. To identify a possible high energy counterpart of FRB121102 when it is active at radio frequencies we propose a 3 orbits INTEGRAL ToO coordinated with a 50 ksec X-ray observation with XMM-Newton (within this common call).We will trigger the ToO when radio bursts will be detected in at least in 2 over 3 one hour long successive observations thanks to the regular daily monitoring of FRB121102 we are currently carrying out with the Nancay Radio Telescope (NRT). Prompt observations with Arecibo and Effelsberg will corroborate the NRT monitoring and then secure a good temporal coverage during the high energy survey.The vast collection of FRB theoretical model so far proposed includes the collapse of an accreting neutron star (NS) or a black hole (BH) giant radio pulses from pulsars giant flares from magnetars NS-NS/NS-BH/BH-BH binary mergers or interaction of asteroids with a highly magnetized pulsar. Assessing the low and hard X-ray emission associated to FRB121102 will tightly constrain the emission processes at play and the nature of the central engine powering these mysterious events and provide clues on their interaction with the surrounding environment.

description: We propose INTEGRAL ToO follow up observations of new Black Hole (BH) X-ray Novae (XN) detected in outburst in the direction of the Galactic Bulge (GB) and which are not subject to Core Program (CP) ToO observations. This proposal is the continuation of the one submitted in AO1 by Goldwurm et al. and in AO2 by Goldoni et al. which were awarded observing time. The first one has been triggered during 2003 and it has already produced valuable data and results on a new faint transient located in the GB (within 10 degrees from the Galactic Centre) region. In this sky region  we expect during the third year of the INTEGRAL mission to observe 1 or 2 faint XN in outburst which will be too faint to fullfill the triggering criteria for CP ToO observations. INTEGRAL offers a unique possibility to study these far absorbed sources which lie in a very confused region of the sky. We propose 2 two day-long INTEGRAL ToO observations on one of these objects to be performed in the following way: the first one as soon as the trigger criteria are satisfied and therefore during the outburst peak the second when the spectral state of the source is changing. Both observations will provide a detailed spectrum from 3 to a few hundred keV which will determine the spectral parameters of the source. This will allow to study the relative contribution of ultra-soft reflection and hard components with their correlation to variability properties. In particular these observations will allow  to search for the rare and variable high-energy emission lines of the type of those detected around 500 keV by SIGMA during the peak of Nova Muscae 1991 with a probable larger sample of XN than the one covered by the CP. We will also carry out correlated multi-wavelength observations  with ground-based observatories. Radio/optical data are essential for astrophysical interpretation of high energy results and in specific we will search for correlation be [truncated! Please see actual data for full text]

description: The mass transfer and accretion mechanisms in SFXTs are key questions to be answered in order to place the SFXTs in the wider context of HMXB systems. Current theories centre on mass transfer via isotropic but inhomogeneous (clumpy) winds but some systems also show evidence of disk-like structures around the supergiant analogous to those seen in Be/X-ray binaries. We propose a campaign of periastron observations of 2 SFXTs with known ephemerides following on from the accepted AO-9 programme Probing the nature of the circumstellar environment around periastron in SFXTs (P.I. Drave PropID 0920016). Using both INTEGRAL and XMM-Newton we will measure the instantaneous accretion rate emission spectrum and time variability generated on and around the neutron star. Now that the orbital parameters of these SFXTs are well-determined targeted continuous broad-band observations around periastron provide us with the best opportunity to use the (assumed) neutron star as a direct probe of the circumstellar wind environment. To achieve the goals outlined in this proposal we request 467ks of fixed time INTEGRAL observations complemented with 80ks of simultaneous XMM-Newton observations. [truncated!

description: A deep observation of the North Ecliptic Pole is proposed. The aim is to reach a factor ~10 lower in flux than achieved previously. A considerable number of new faint sources are expected which will be used to test the validity of population synthesis models which try to reproduce the X-ray background spectrum. Some of the faint sources will be Compton-thick AGN. The sample of sources will also be used to study the dependence of the obscured-to-unobscured AGN ratio with either redshift and/or luminosity and thus to test the AGN unification model. The good high-energy response of IBIS and SPI will be used to test the presence of a high-energy (>100 keV) cut-off in the AGN spectra of the brightest objects and in the stacked spectrum of all the detected AGN.

description: This proposal aims at obtaining the deepest hard X-ray extragalactic survey at studying the keV to GeV spectrum and hard X-ray variability of the brightest quasar 3C 273 and at measuring annihilation and hard X-ray emission from the central region of the Virgo cluster. Current INTEGRAL observations of the 3C 273 field already provide the deepest hard X-ray extragalactic survey ever made. With the additional exposure we aim at reaching a flux limit of 0.1 mCrab. This will allow to detect sources with typical luminosity up to a redshift of 0.1 probing the evolution of AGN in the hard X-rays over the last billion years. It will also allow to study the implication of absorption for the cosmic X-ray background the absorption/luminosity relationship and the local AGN luminosity function. SPI is the only available instrument for the next decades to be able to detect the presence of anti-matter in the jet of 3C 273. This detection would have profound implications on models explaining jet creation acceleration and collimation as well as the high-energy emission of AGN. The three other instruments of INTEGRAL have enough sensitivity to follow the complex spectral variations of 3C 273 from the optical to the hard X-rays in coordination with GeV measurements by Fermi. This is a unique opportunity to study the correlations between the various emission components of 3C 273 from the eV to the GeV range and compare them with model predictions. Such observations have far reaching implications. Key observations will finally be obtained on the hard X-ray emission of M87 probably generated by interaction of its radio bubble and the cooling flow of the Virgo cluster as well as on the expected cluster annihilation emission.

description: The dynamically confirmed black hole binary GS 2023+33 better known as V404 Cyg recently entered the outburst phase (June 2015) after 26 years of quiescence stirring the interest of the entire astronomical community.At 05:19:52 UT Swift /BAT triggered and located V 404 Cyg (GCN CIRCULAR 18716 trigger=668097) after an hard X-ray flare. Swift did not slew due to a low merit value but we have already triggered a Swift monitoring on the source to follow a possible re-brightening. ow showing faint X-ray flux (about 45mCrab) and is observed in radio  (fluxes 22 +-5 33+-5 45+-10 mJy at 4.6 8.2 and 11.2 GHz  respectively Atel #8454) and in optical (with a variability of half a magnitude on time scales of 10min Atel #8453). Radio and optical follow up have been planned already. V404 Cyg might be therefore active again only 6 months after its last outburst. We therefore require an INTEGRAL ToO to observed this unique event. We ask for a long observation (1Ms) to be started as soon as possible in order to cover at best the starting phases of what might be a new outburst of this unique source. INTEGRAL will be able to observe V404 Cyg only until the 6th of February it is therefore of high importance to start the observations as soon as possible as INTEGRAL is the only X-ray observatory able to provide long uninterrupted observations fundamental to study the extremely variable behaviour of this system. We request the observations to be scheduled using the INTEGRAL Hexagonal pattern (HEX) in order to have the source within the field of view of the JEM-X and OMC monitors over the whole observation.
