description: For as long as X-ray astronomy exists X-ray (and gamma-ray) astronomers consider the Crab supernova remnant to be a steady standard candle suitable as a calibration source. INTEGRAL has been observing the Crab for mainly calibration purposes only about twice per year for a total of about 4 revolutions per AO up to AO-11. Further observations have been sparse and only every now and then it was in the field of view during a few ad-hoc observations of relatively nearby sources. In AO-11 we started a program to monitor the Crab more frequently on a regular basis. We propose to continue this project. The objectives are two-fold: 1) monitor and seek for accompanying flares which have been seen at $>$100MeV by Fermi and AGILE 2) improve on the (cross-) calibration of the INTEGRAL instruments as well as with other high-energy instruments. We propose to look at the Crab every 4th revolution with a single standard 5x5 pattern for 45 ksec. The data will be made public immediately. [truncated! Please see actual data for full text]

description: 3C273 is the brightest active galaxy in the sky in almost allwavebands from radio to low energy gamma-rays (eg Courvoisier etal1990).  The large majority of its emission comes from a relativisticjet oriented towards the observer. The radio through optical emissionis synchrotron emission and the X- and Gamma-ray emission almostcertainly comes from Compton scattering of low energy seed photons byrelativistic particles in the jet. However the origin of the seedphotons and the way in which the scattering particles are acceleratedin the jet are unknown. INTEGRAL spectral quasi-monitoringobservations of 3C273 (10 observations of 50ksec each separated by 5days during one observing window) coupled withdaily X-ray monitoring with RXTE and ground based monitoring ofthe low energy synchrotron continuum provide the idea way to answerthese questions.  Previous Gamma-ray observations have been completelyinadequate.  Although not a major part of this proposal we will also be able to detect red and blue shiftedannihilation lines which will enable us to determine what the jet isactually made of. [truncated!

description: We propose to observe the Cassiopeia A and Tycho in order to constrain the production of various X/gamma-ray emitting particles by supernovae (SNe) and their remnants (SNRs). In AO-7 we argued that significant advances can be made with an additional 7Ms of exposure on these objects and we were granted 1.5Ms. We now require the continuation of the effort with a further 2Ms in AO-8. SNRs are established sources of cosmic-rays. A better characterisation thanks to IBIS of the hard X-ray spectra from both Cas A and Tycho will allow a better interpretation of the non-thermal emission from these objects. These observations are of great importance to constrain the maximum energy to which electrons are accelerated and the turbulent magnetic field and diffusion regime two key ingredients of the diffusive shock acceleration theory. SNe and SNRs are also considered as the most likely sources of the galactic positrons through the beta-decay of some of their nucleosynthesis products. It is still unclear which fraction of these positrons can escape SNe and SNRs to flow into the interstellar medium and feed the Galactic diffuse emission at 511keV observed with INTEGRAL. Constraining the 511keV emission from Cas A and Tycho with SPI will give valuable information about the positron escape fraction and transport which are central to a full understanding of the leptonic antimatter content of our Galaxy. Stellar explosions also produce radioactive isotopes like 44Ti that upon decay give rise to gamma-ray line emission.The nucleosynthesis of 44Ti is highly sensitive to the physical conditions of the explosion. Observations with SPI and IBIS can help to identify at what location in the exploding star the 44Ti is produced and thus be a significant contribution to the understanding of the mechanisms by which stars explode. In addition to these topics the Cassiopeia field harbours many hard X-ray sources to the study of which IBIS can s [truncated! Please see actual data for full text]

description: Two years ago we initiated a multi-year program (AO-16 and AO-17) aimed at creation of an ultra-deep extragalactic field in the direction centered on galaxy M81. We now request new INTEGRAL observations in order to continue our program. This ultra-deep field will become INTEGRALs legacy for studies of the AGN population at hard X-ray fluxes as low as fewx10^-12 erg s^-1 cm^-2 and shall provide a ground for unique synergy of INTEGRAL with the all-sky X-ray surveys by the eROSITA and ART-XC telescopes on board the SRG observatory which began in December 2019. We ask for additional 5 Ms of INTEGRAL observations 2.5 Ms in AO18 (2021) and 2.5 Ms in AO19 (2022) to reach a sensitivity of 2x10^-12 erg cm^-2 s^-1 in the 17-60 keV energy band by the midtime of the SRG 4-year all-sky survey.

description: Evidence continues to build that the soft gamma repeaters (SGRs) are  magnetars objects in which the magnetic field energy dominates all other energy sources including rotation.  This implies that they posess the strongest known magnetic fields in the universe (10^15 G).  SGRs go through phases of intense activity during which they may emit hundreds of bursts within a period of weeks to months.  During those periods they exhibit properties which are quite different from their quiescent properties.  Their strong magnetic fields are probably mainly responsible for these changes and accordingly it is interesting to study them intensely at these times.  We propose to continue our successful AO-1 and AO-2 proposals and request two ToO observations of any of the known or of any newly discovered SGRs during their active phases.  We request that the ToO take place within one month of the trigger.  For clarity we have filled out one observation form for each of the known SGRs and for one unknown SGR.  Our total request however is for just TWO ToOs.  This is one of two SGR proposals being submitted by nearly identical teams.  The other proposal (M. Feroci  and  K. Hurley Co-PIs) requests data on SGRs serendipitously detected by INTEGRAL.  Although the scientific justifications of the two proposals are nearly identical the proposals are independent of one another in the sense that the objectives of each can be achieved without the acceptance of the other.

Observations of the GC region make the best use of the unique INTEGRAL capabilities and undoubtedly are the most efficient investment of its precious observing time. The main objectives of the proposed observations are the monitoring of Sgr A* and three dozens of black-hole or other peculiar X-ray binaries including a search for new transient sources and phenomena.

description: Swift/BAT and INTEGRAL/IBIS have revolutionized our view of Active Galactic Nuclei (AGN) in the local Universe. While their successful ongoing surveys count hundreds of AGN essential issues related to properties and evolution of AGN call for more sensitive surveys rather than larger numbers of AGN. To address these issues we have developed a new survey technique by merging the independent observations of BAT and IBIS/ISGRI: the Swift-INTEGRAL X-ray (SIX) survey. This survey capitalizes on the very uniform BAT sensitivity over the entire sky and the very deep sensitivity of IBIS/ISGRI over selected sky areas. Here we propose to perform a very deep IBIS/ISGRI survey of 9 Ms over a selected sky area in order to obtain the most sensitive survey of the local Universe. We will use the SIX survey to study properties and evolution of AGN in the local Universe. This will be the reference sample of local AGN in terms of redshift  luminosity parameter space. Our simulations of the proposed observations show that the lowest fluxes will be sampled on a sky area of ~300 deg^2 that is much larger compared to what NuSTAR can cover with its focusing optics. Only IBIS/ISGRI observations can lead to these achievements. [truncated! Please see actual data for full text]

description: We propose to continue our Key Programme that consists of high-cadence monitoring of the inner spiral arms of the Galaxy with INTEGRAL paired with ToO observations of new transients with XMM-Newton and Swift. The INTEGRAL Spiral Arms (ISA) program (25.6 ks per spacecraft revolution during visibility periods for a total of 1.2 Ms) complements the successful Galactic Bulge (GB) program by extending the monitored region of the Galaxy to the Inner Perseus/Norma Arm tangents on one side of the GB and the Scutum/Sagittarius Arms on the other. These fields feature a high density of obscured high-mass X-ray binaries (HMXBs) including Supergiant Fast X-ray Transients (SFXTs) as well as other hard X-ray emitting sources (e.g. microquasars low-mass X-ray binaries and magnetars) that INTEGRAL is well-suited to finding thanks to its large field of view and angular resolution at high energies even in crowded regions of the sky. Mosaic images and source light curves in 2 energy bands for ISGRI and JEM-X are being provided to the community (http://sprg.ssl.berkeley.edu/~bodaghee/isa/) permitting rapid dissemination of results which enable prompt follow-up of interesting events. The ISA project represents the cornerstone of our ongoing study of transient and variable hard X-ray populations in the Milky Way. [truncated! Please see actual data for full text]

description: This proposal is aimed on obtaining legacy-level observational datasets on the Milky Way Galactic disk.  The ultimate goal of the entire project is to have model independent and systematics free measurements of the fluxes in nuclear lines (511 keV annihilation emission 1.8 MeV Al26 and 1.17 MeV and 1.33 MeV Fe60 lines) and a broad band spectrum of the Galactic background emission which at different energies is provided either by cumulative emission of faint Galactic sources or by interaction of low energy cosmic rays with interstellar medium. Taking into account the unique combination of properties of the INTEGRAL instruments - broad band coverage large fields of view and possibilities to eliminate the contribution of discrete sources from the total measured photon flux the proposed strategy is the best possible usage of the valuable INTEGRAL time. Wide mapping of the Milky Way during the campaign of Galactic latitude scans also contributes to the legacy of the INTEGRAL observatory giving the opportunity to study the population of Galactic sources at high latitudes.

The IXPEobservation plan foresees for the second year of operations 5 ToOs devoted to continue the study of transient blackhole X-ray binary target. The combined IXPE/INTEGRAL observations in this case will be a unique opportunityto provide a broad-band X-ray spectroscopy and a simultaneous measure of the X-ray polarization. This will resultin an unprecedented view of the system geometry and the role of jets and corona in X-ray binaries. This proposalhas already been accepted in AO18 and AO19.

description: We propose to observe 3C 273 during each of its visibility periods (twice per year) for two long (200 ksec) observations one at the beginning and the other at the end of the period and several short (10 ksec) observations in between. This will provide us with a set of data to investigate the high energy emission of the brightest quasar with unprecedented sensitivity and time sampling from few keV to several MeV.We will study both the Seyfert type emission and the jet related emission. We will see at which energies each of these components dominates and how it varies. We will thus establish the nature of the high energy emission measure the temperature of the Comptonising medium measure the properties of the electrons and positrons in the jet and measure the properties of the MeV spectral break. Our programme will be coordinated with a large multi-wavelength set of observations to relate the high energy components with those observed at lower energies specifically the synchrotron emission of the jet and the blue bump.

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 3.0 Ms of observations in AO18 and 3 Ms in AO19 to continue our KeyProgram covering areas of the Plane with regular scans every orbit. For these AOs we selected again the section of the Plane incorporating two sky regions centered at l=+/-30 that are both rich in galactic sources (LMXB and HMXB SFXT inparticular) 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 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 avery 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 been through AO8-17 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 already been demonstrated.
