description: The most fundamental parameters in black hole (candidate) X-ray binary systems e.g. the mass accretion rate the geometry of the accretion flow the production of radio-bright jets are tied intimately to the distinct spectral and timing states observed in these sources.  Yet despite study in many energy bands the mechanism(s) driving transitions between these states remains unclear.  High-resolution spectroscopy of the hard-X-ray/soft-gamma-ray band is hitherto unexplored territory but there are strong indications that the answer to black hole state transitions may be contained in this domain.  We have designed a program that will bring Integral to bear on the problem of black hole states supported by a global simultaneous multi-wavelength effort which spans the radio IR optical and soft X-ray bands and by a team of experienced observers and theorists.

description: We would like to follow-up on this source with INTEGRAL and fit it in with the wealth of observations done and to be triggered at various wavelengths (such as possibly Chandra). The exact nature of the compact object is not yet known  INTEGRAL will play a crucial role in helping identifying it. It may be a new Galactic micro-quasar like GRS 1915+105 of which only a few are known and which show extreme behaviour especially at hard X-ray and gamma-ray energies. [truncated!

description: The goal of this proposal is to better understand the low-flux state and long-term behaviour of blazars at high-energies by studying Mrk 421 with a combination of observations from X-rays to TeV gamma rays.  The programconsists of two observations of 370 ks each one in each of the visibility periods in May-June and Nov-Dec. Theseobservations  will  be  enhanced  with  2 ks  snapshots  with  focusing  X-ray  instruments  (XMM-NewtonandSwift)and public monitoring programs of the source by Fermi andSwift/XRT. The energy ranges covered respectivelybyINTEGRALandFACTare crucial for modeling the spectral energy distribution (SED) of blazars.  Based onan examination of allINTEGRALdata the best candidate among theFACT-monitored TeV blazars is Mrk 421.Short-term variability in high-flux states and flaring are covered by other ToO programs. We want to investigate theevolution of the SED on the timescales of months and with this constrain blazar emission models.INTEGRALisessential for this as it measures the energy region at the decline of the low energy peak and the valley between thelow and high energy peaks. In addition we want to investigate if Mrk 421 exhibits a peak shift and thus a tendencyto extreme behaviour akin to that seen in Mrk 501 and 1ES 2344+51.4.  To do so we want to compare the resultsof two observations.  Past observations (last one in 2015) have been triggered by the high state of the source andare therefore not suitable for our study.  We need these longer observations to learn about the sources long-termbehaviour. There are no long-term observations in the hard X-rays. Any outcome of this study will therefore providean unprecedented look into the high-energy emission of blazars in their non-flaring state [truncated! Please see actual data for full text]

description: The Perseus OB2 association is the second closest (300 pc) massive star region and is about 6 Myr old. Among its stellar content of approximately 20000 stars there are 17 high-mass stars of spectral type B. Since the birth of the stellar group already the most-massive stars exploded and enriched the surrounding interstellar medium with freshly-produced elements. This is direct evidence for ongoing nucleosynthesis in the Milky Way. One of the most important tracers of this chemical enrichment is the beta+-unstable isotope 26Al. The decay of radioactive 26Al nuclei as observed by gamma-ray line at 1808.63 keV provides a unique tool to study the effects of massive stars onto their environment the feedback scenario. This is only possible with SPI aboard INTEGRAL.Previous 26Al studies focussed on other prominent massive star regions such as Cygnus Orion and Scorpius Centaurus. These associations are well studied in kinematics (Doppler-shift and -broadening) and 26Al content (flux mass). However the morphology of the 26Al emission cannot accurately be modelled there as either the signals are too weak or the galactic background emission is glaring into the desired region. Per OB2 is located in the galactic anti-centre and below the galactic plane probably associated with the Gould Belt and thus predestinated for 26Al observations.In this proposal we ask for a 3 Ms two-year observation campaign towards the direction of Per OB2 in order to:1) validate and refine the previous measurements with COMPTEL and SPI (2.9 Ms) 2) measure the kinematics of the 26Al ejecta from the congeries of Per OB2 stars and supernovae 3) determine the spatial distribution of 26Al with respect to the Perseus supershell 4) search for 60Fe gamma-rays at 1173 and 1332 keV from a spatially distinguished OB association 5) provide another measure of the 1.8 MeV foreground emission towards a galactic-wide picture.

description: We propose to continue the monitoring of the X-ray brightest Seyfert galaxy NGC 4151 with integral in order to measure its spectra as a function of the hard X-ray flux level. We will correlate the high energy spectral cutoff with other continuum parameters to determine the main physical mechanism driving the variability. We will also disentangle the contributions to the reflection hump from close and distant reflectors 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. We request four observations of 200 ks each for which we will propose four 10 ks accompanying XMM-Newton observations. [truncated!

description: We propose a 500 ks long INTEGRAL observation of the X-ray pulsar 4U 1626-67 to fully constrain its spectral shape in the hard X-ray band. This X-ray pulsar is rather peculiar among its class as it shows a resonant cyclotron feature at 37 keV (indicating a magnetic field of a few 10E12 G) but the companion mass is a very low-mass star (less than 0.08 Msun). A recent observation made with NuSTAR revealed a complex spectral curvature in the 50-70 keV band that could be accounted for by a moderately broadened absorption line at 61 keV. This could be the second cyclotron harmonic even though its energy is lower than the expected value. INTEGRAL is presently the only observatory able to definitively detect this feature and constrain its parameters. [truncated! Please see actual data for full text]

description: We propose INTEGRAL observations of the sky region around the quasar PKS 0208-512. This region contains hundreds of X-ray sources which could be potential hard X-ray emitters. Among them CGRO highlighted the quasar PKS 0208-512 as a gamma-ray source and a possible MeV blazar. A re-analysis of the COMPTEL/CGRO data clearly reveals a persistent soft gamma-ray emission in itslowest energy band (0.75-1 MeV). The flux of this excess is well above the extrapolation of the EGRET spectrum suggesting a so-called MeV-blazar origin. An alternative possibility would be that this emission is not due to PKS 0208-512 instead is emitted from one or several neighboring sources which cannot be resolved by COMPTEL. The proposed INTEGRAL observation would shed light on this soft gamma-ray emission by resolving for the first time this sky region at hard X-rays. It could discriminate whether PKS 0208-512 is a MeV-blazar and so has an additional emission component or whether the emission is due to sources in the surroundings of PKS 0208-512 i.e. it will clarify the nature of this enigmatic soft gamma-ray emission.

description: Massive stars and their impacts on their surrounding interstellar medium drive the stellar feedback process one of the main astrophysical issues in the context of galaxy evolution and cosmic chemical evolution. Radioactivity from 26Al adds a unique diagnostic tool for its investigation in nearby massive-star regions. The Orion region hosts one of the closest such regions at a distance of ~400 pc  there is hardly a more suitable and closer target region. COMPTEL had provided a measurement of 26Al 1809 keV emission from this region confirming this opportunity. An interesting offset of the diffuse and extended 26Al emission source from its likely sources suggests champagne-like outflow from the OB1 association stars into the Eridanus cavity. HI filaments in radio emission X-ray emission seen with XMM-Newton and GeV emission seen with Fermi-LAT all support this  together with Gaia details on the stellar population this is an ideal setting for a multi-messenger study of feedback 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: With INTEGRAL gamma-ray measurements we can constrain 26Al ejection from massive stars in mass and velocity and 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. Analysis of previous INTEGRAL observations has obtained a firm detection of the expected signal from 26Al. With our proposed multi-year deepening of exposure (3 Ms in AO-18) we aim to improve our measure of the line shape and thus kinematics of this nearby 26Al source. With these observations we can also search for annihilation radiation and for  nuclear deexcitation gamma-rays in the MeV range both valuable diagnostics of the structure of superbubble interiors and >30 Fermi  [truncated!

description: We propose observations of 2 brightest Seyfert 1s NGC 4151 and IC 4329A with exposure of 7.5E5 s each. The main goal of the observations is to accurately measure the shape of their high-energy >100 keV spectra. This will allow us to determine the relative contribution of thermal and non-thermal Comptonization in the sources. The presence of non-thermal Comptonization will lead to power-law like tails as well as broad pair annihilation features beyond the thermal cutoff. Such measurements will have profound theoretical consequences. Furthermore we will study short-time scale variability of the sources and correlations between various spectral components. This will further constrain the physical processes and geometry of the sources. The field of view of IC 4329A also contains the famous MCG-6-30-15 which spectrum we will measure as well. For all observations we will apply for XMM time to provide simultaneous detailed measurements of the Fe K line and edge complex. [truncated! Please see actual data for full text]

These observations will provide an opportunity to use INTEGRALs unique capabilities to explore the hard X-ray/Gamma-ray emission. which occurs during jet production in this system.  We present evidence for the production of highly relativitic jets that have a corresponding hard X-ray/Gamma-ray emission.  The proposed observations will allow us to examine the nature of this emission and possibly detect the presence of annihilation lines.  Additional if lines are detected and have Doppler shifts we can directly measure the speed of the important step towards solving the problem of what jets are made of. [truncated!

description: There is good evidence 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 possess 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-1-5 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 for one suspected SGR and for one unknown SGR.  Our total request however is for just TWO 240 ksec ToOs.   [truncated! Please see actual data for full text]

description: We propose to continue and complete our program for observing the sky at intermediate Galactic latitudes above and below the Galactic bulge with the goal of establishing with INTEGRAL for the first time the large-scale spatial distribution of positron annihilation radiation and its spectral charateristics. This is crucial for identifying the origin(s) of the copious positrons in our Galaxy and for understanding their diffusion in the interstellar medium.We have published the first sky maps in the 511~keV line citep{Knoedlseder05} and in the positronium continuum citep{Weidenspointner_etal_06} which clearly showed that the positron annihilation radiation from our Galaxy is brightest around the Galactic center. Subsequent work showed that all but two scenarios remain for the Galactic distribution of positron annihilation radiation: ``bulge + thick disk or ``halo + thin disk citep{Weidenspointner07}. We propose to break the current degeneracy between viable scenarios byobserving at intermediate latitudes south of the Galactic bulge ($l = pm 20^circ$ $b=-20^circ$) for a total of 2~Ms. These observations will help to deepen and homogenize the exposure around the Galactic bulge a prerequisit for obtaining the best possible results on the intriguing annihilation emission observed from intermediate latitudes in the inner Galaxy.

description: The structure and energetics of the innermost regions of black holes are still matter of debate.In particular a lot of the attention is given to the understanding of the surrounding material close to the black holeas well as to the connection of the inflowing and the outflowing material in disks winds and jets. We have identified the Seyfert galaxy NGC 2110 one of the brightest AGN at hard X-rays as an ideal laboratory to investigate both issues through its multi wavelength variability. On one hand  variable absorption has been measured in the past in the form of partial covering material.On the other hand NGC 2110 might represent a transition object between a radio quiet and a radio-loud galaxy. Variability has been observed at 8.4 GHz with the VLA (with decrease of ~40% in flux over 7 years).Here we propose to observe NGC2110 with INTEGRAL for 860 ks followed-up by Swift(XRT) and VLBA observations with the main aim of characterizing for the first time the absorption variability over days timescales and test the connection between the X-ray and radio emission lookingfor possible multi frequency time lags.

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 140 of them with one hexagonal pattern about every 3 days whenever it 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 will provide 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. Because of the new format since AO-7 and as a service to the scientific community the observations are to be made public immediately. We intend to continue to make the IBIS/ISGRI and JEM-X quick-look results publicly available through the web as soon as possible after the data are made available so to preserve the possibility for rapid follow-up by the community.
