description: The Galactic bulge region is a rich host of variable X-ray and gamma-ray point sources. Since AO-3 we are monitoring about 190 of them with one hexagonal pattern about every 3 days whenever the region is visible by INTEGRAL. Due to the high scientific return and in order to preserve the continuity with respect to past observations of this ever-changing region we propose to continue our successful program. Our main aim is to monitor and actively report on any (transient) activity  in the long run the program is providing regular and homogeneous inputs about the soft and hard-X-ray (transient) population as well as on the accretion regimes in the various types of binary systems. As a service to the scientific community the observations are to be made public. We will continue to make the IBIS/ISGRI and JEM-X quick-look results publicly available through the web soon after the data have been taken to preserve the possibility for rapid follow-up by the community.

description: The famous HMXB Vela X-1 has in recent years also be found to emit in the radio. The detection took place by chance while the X-ray source was in eclipse. In the coming days there will be further radio observations (ATCA plus MeerKat for the 2nd and 3rd) spaced out around the binary orbit to find clues on the unknown radio emission mechanism. A NuSTAR DDT has in the meantime also been approved. We would like INTEGRAL data to cover time around and covering the coordinated observations in order to enlarge the covered energy range and especially to have a better handle on the source variability before during and after the radio + X-ray observations. Other X-ray observatories (XMM-Newton NICER) are visibility constrained. Some Swift coverage will be done.  [truncated! Please see actual data for full text]

description: The simultaneous optical-to-gamma-rays observations of blazars are key tools in understanding the nature of these sources the mechanisms of the gamma-ray emission and other features such as the origin of the soft X-rays (E < 1 keV) photon deficit often observed in high-z flat-spectrum radio quasars. We therefore ask for two 500 ks observations with INTEGRAL (total requested exposure 2x 500 = 1000 ks) of the two high-redshift blazars PKS B2126-158 (z = 3.268) and PKS B2149-307 (z = 2.345). These observations coupled with simultaneous Swift and GLAST observations will allow us to build the best available optical-to-gamma-rays spectral energy distributions which in turn will be modeled and studied in order to give answers to the above mentioned problems.

description: Investigating the poorly understood accretion mechanism producing the short flares observed from the SFXTs is a key tool in placing these X-ray binaries in the wider context of the HMXBs. Studies of this X-ray binary class are fundamental to understanding the evolution of massive stars to determining the chemical enrichment of the Galaxy and to give a significant contribution to studying the neutron star equation of the state. Current theories are based on a mass transfer via an isotropic and inhomogeneous clumpy wind or via accretion from anisotropic supergiant wind or on the high magnetic field of neutron stars (>10^14 G) regulating the duration and peak luminosity of the outbursts.Outbursts of IGR J16328-4726 occur at a restricted phase range (likely near to the periastron passage) of its orbital period (10.0680.002 days) allowing us to predict them and to plan pointed observations. We propose two short (~20ks) XMM-Newton observations simultaneous with long (200 ks) INTEGRAL observations performed at periastron.Using both XMM-Newton and INTEGRAL instruments we will measure the instantaneous accretion rate the broad band spectral shape and the absorption column density local to the source. These simultaneous observations will provide us with the best opportunity to know the circumstellar wind environment needed to discriminate between different physical mechanisms proposed to explain SFXTs.

description: Cyg X-1 is the best candidate to understand the X/gammaray emission of Galactic X-Ray Binaries. Being the hardest and brightest persistent one it offers the unique opportunity to get crucial information about the phenomenon at work in its central parts where accretion and ejection thermal and non-thermal mechanisms as well as other complex physics coexist. A lot of work has been done recently with major results in the spectral timing and polarisation fields around this object. This strongly encourages us to pursue our effort with deep and continuous analyses. Since more than 4 years Cyg X-1 is staying in an unusually long Soft State interrupted by some tentative incursions in Intermediate/Hard states. Both the Soft State periods and the hardening episodes conceal invaluable information on the source behaviour. Long accumulation time is required if one wants to reveal the real source behaviour above 100-200 keV in particular the polarisation properties in the Hard and Intermediate States the spectral evolution during the Soft States as well as timing properties in all states. The monitoring of the high energy part of the Cyg X-1 emission along with the corresponding polarization properties their variability and the correlation between different parameters (source intensity hardness polarisation fraction) potentially in the different spectral states will reveal us the roles played by the various ingredients present in this source and its analogues. Note furthermore that the region of Cyg X-1 is very rich of different targets mostly High Mass X-ray Binary systems and will also open a large field of additional science for the INTEGRAL users.

description: For the first 5 years of INTEGRALs operational life the scientific Core Programme included a key component that was regular scans of the Galactic Plane. These led to a wealth of discoveries of new sources and source types a large fraction of which were highly transient. These discoveries can certainly be considered one of the strongest results from and legacies of INTEGRAL. Since AO-5 these regular scans have been discontinued and this has resulted in a significant drop in the discovery rate of new systems in and around the plane of our Galaxy. We propose to reinstate the Galactic Plane Scans as a Key Programme throughout AO8 and AO9 to allow the regular monitoring of known systems and dramatically enhance the chances of discovering new systems. 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.To this aim a total of 2 Msec /year are necessary to cover the plane with regular scans every orbit excluding the central zone to be covered by the Galactic Bulge monitoring programme (should that programme be accepted). We also suggest that in order to maximise the engagement of the scientific community the observations should be made public immediately. The team will make the IBIS and JEM-X light curves in two energy bands per science window and per observation as well as the mosaic images publicly available through the web as soon as possible after the observations have been performed. Any interesting source behaviour that emerges from our observations will be announced promptly so that rapid follow-up by the community is possible. [truncated! Please see actual data for full text]

The scientific aim of this campaign is to measure a high signal to noise spectrum of Cyg X-1 from 0.5 to above 600keV allowing us to constrain models for the Comptonizing plasma responsible for the hard X-ray spectrum to constrain the amount of Compton reflection in the system to provide the >10keV continuum above a possibly relativistically broadened Fe Kalpha line and to search for and study the effects of non-thermal Comptonization and/or synchrotron self-Compton emission from a jet.

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 and 1.8 MeV Al26) and a broad band spectrum of the Galactic background emission which at different energies is provided either by cumulative emission of faint Galactic source or by interaction of low energy cosmic rays with interstellar medium. Taking into account the unique combination of properties of 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.

description: We propose to observe Cas A and Tycho with INTEGRAL for 2.5 Ms as a continuation of our existing observation program. Cas A is a known source of  Ti-44 line emission but with INTEGRAL we can improve the flux measurements and moreover measure or place limits on the  velocity line broadening. This is of great importance for the current debate about the nature of core collapse supernovae as Ti-44 probes the inner regions of the explosion. With an additional 2.5 Ms exposure we will be able to detect the continuum emission above  ~90 keV. This is important for constraining the continuum underneath the 68 keV and 78 keV lines and it will cast a new light on the nature of the hard X-ray continuum which is presently not known.For Tycho the likely remnant of a Type Ia supernova the goal is to detect Ti-44 line emission or provide stringent upper limits to it. This can establish or rule out that SN 1572 was a sub-Chandrasekhar mass Type Ia event.  Moreover with INTEGRAL we will be able to detect Tychos hard X-ray continuum above 30 keV and at least up to 60 keV for the first time.   Such measurements are essential for investigating the nature of these hard X-ray tails and for constraining the  models of particle  acceleration in supernova remnants. [truncated!

description: In recent years thanks to the study of the correlated X-ray/OIR fast variability in Low Mass X-ray Binaries (LMXRBs) a new window on jet physics was opened: thanks to the detection of the subsecond variability in the jet emission it has been possible to measure the jet speed and size. Sco X-1 is a Neutron star LMXRBs which shows dramatic X-ray variability linked to changes in the nature of the accretion inflow to which is also associated strong radio activity from the relativistic jet. Here we propose to observe Sco X-1 with INTEGRAL using high time resolution modes to be matched in strict simultaneity with HAWK-I@VLT. We will measure the jet speed and study how these jet properties vary and evolve in the different accretion regimes of the source. Coverage in other bands will be also asked with other telescope in other bands (i.e. VLA REM...). We ask to perform 2 observation of 100ks each. [truncated! Please see actual data for full text]

description: One of the key investigations so far performed by the INTEGRAL Observatory after six years of operation has been the soft gamma-ray GCDE and the GPS successfully exploited to a depth of better than 1 mCrab in the central region with unprecedented details due to the >20 Ms exposure on 5x5 squared degree centred on SGR A*. More recently the new INTEGRAL view of the extragalactic soft gamma-ray sky has been complemented by the excellent sky coverage provided by the SWIFT/BAT extragalactic survey overlapping the IBIS one in lower energy range (E<200 keV). SWIFT has now achieved a deeper average sensitivity for the extragalactic survey while INTEGRAL has a almost a factor of 10 better sensitivity over the Galaxy plane due to the 5Ms average exposure. This true for the whole plane but for two important regions that are only covered at a level of 1Ms and 2 Ms respectively: the two regions are basically coincident with the outer Perseus spiral arms. In those regions the material is considerably less dense and we will be able to extend our present studies of compact objects through a detailed comparison of the relative populations of all classes of gamma-ray emitting galactic types in the very different environment provided in these outer regions. A more complete understanding of our high energy galaxy will be the result. Finally last but not least this is a unique opportunity to obtain a deep so ft gamma ray coverage of the Galaxy plane: an invaluable INTEGRAL Legacy for futurfture high energy studies.This proposal is specifically designed to reach this goal thus making a corner stone in the high energy understanding of our Galaxy behaviour in the 17-600 keV range and provide a text book for future soft gamma-ray population studies and focus future gamma-ray missions scientific objectives as per Simbol-X EXIST and ultimately IXO.

description: Black Holes (BH) in the thick disc and/or halo of the Milky Way  galaxy appear sporadically as X-ray Novae (XN) with very hard spectra.  The origin of these objects are among the most intriguing problems in high-energy astrophysics: they could have been shot out from the Galactic Plane (GP) or be pristine BH formed in the galactic halo before the galactic disc was formed. At latitudes |b| > 5 deg BH XN are likely to be close to the Sun bright optically unobscured  the compact radio counterpart is subject to low interstellar scattering. The proposed study will allow to: 1) probe the connection between accretion disc instabilities and the formation of relativistic jets in all wavelength bands  2) know whether the radio infrared and optical non-thermal components and the gamma-ray events originate -as recently found in quasars- within the same shocked area downstream the relativistic jet and 3) determine the space velocity of the binary centre of mass to know where these BH come from. The discovery of XTE J1118+48 (62 deg off the GP Lx < 1e36 erg/s at its peak) rises the suspicion that we may have so far missed a large population of BH in the galactic thick disc and/or halo. We wish to know whether there are fundamental differences between BH in the halo compared to BH in the disc. Furthermore some of these accreting BH in low mass X-ray binaries could be micro-blazars  it is still an open question their possible relation to a subset of soft and variable unidentified EGRET sources that are spread at medium/high latitude most assembled within 30 deg from the Galactic Centre (GC). In the framework of Target of Opportunity (ToO) observations we aim to observe new BH XN at |b| > 5 deg not subject to INTEGRAL Core Program ToO altogether with multiwavelength observations with UV/opt/IR/radio telescopes.

description: We propose to observe Her~X-1 during INTEGRALs AO-12 for a total observing time 400 ksec: covering a substantial part of one ``Main-On with two  INTEGRAL revolutions the first near the maximum of the ``Main-On the second during its decay.Our general objective is to continue the long-term covering of this enigmatic source by INTEGRAL in order to investigate the physics of generating the cyclotron line and the reasons for thevariability of E_cyc in particular as a function of time. There is now clear evidencethat E_cyc decreased by >4 keV between 1996 and 2012. The physics behind this behavior is not understood so far but is most likely connected to fundamental aspects of highly magnetized neutron stars: its structure and the physics of accretion. We speculate that the decrease of E_cyc is due to a progressing burial or screening of the magnetic field at the polar cap by the continuing accretion. The observational result of the secular decay of a cyclotron line energy is unique and was only possible through an intense effort of monitoring Her~X-1 with all satellite instruments capable of covering the hard X-ray range. A further objective is to continue to investigate the variation of E_cyc as a function of luminosity and of phase of the 35 day variation. In case ofacceptance of this INTEGRAL proposal NuStar will make every effort to schedule acoordinated observation. [truncated! Please see actual data for full text]
