description: We propose to monitor the recurrent neutron star transient GRO J1008-57 during the predicted outburstof the source with INTEGRAL-AO11 in 2014 January with one 50 ks observation per revolution resulting ina total exposure time of 150 ks during 3 INTEGRAL revolutions. Several type I outbursts of GRO J1008-57have been observed in the past as ToOs by Swift RXTE and also Suzaku showing that the spectral shape remains constant between regular outbursts. No cyclotron absorption feature has been detected significantly in the spectrum. Since we were able to improve the orbital ephemeris (Khnel et al. ATEL #4564) it is now possible to predict the onset and maximum of future outbursts of the source to better than 5 days. The source underwent an irregular giant type II outburst in 2012 November (Nakajima et al. ATEL #4561  Krimm et al. #4573) during which a cyclotron absorption feature was claimed between 74 and 78 keV (Yamamoto et al. #ATEL 4759). We therefore propose to observe the system again after the giant outburst to confirm the claimed cyclotron line. In addition we will check on any changes of the spectral and temporal behavior during known type I outbursts. [truncated! Please see actual data for full text]

description: We ask for 2 observations of 500 ks each to observe in target-of-opportunity (TOO) up to 2 blazars conditional to stringent and well defined triggering criteria based on optical and/or X-ray brightening. Serendipitous detections of bright blazars by INTEGRAL itself and by Swift/BAT will also be instrumental to TOO activation. By coordinating these INTEGRAL observations with XMM-Newton campaigns we will guarantee the coverage of a crucial energy range for determining the overall spectral distribution of blazars in a flaring state and thus for constraining any emission model as proved by the success of a similar program conducted in past years with BeppoSAX.=======Please note that the exposures indicated in the Observation Details Panel are purely indicative only to fill the form. The required time is 2 observation of 500 ks each in ToO. [truncated! Please see actual data for full text]

description: Luminous accretion powered neutron stars generate majority of their X-ray emission in optically thick accretion disks and boundary/spreading layers. Numerous experiments in hard X-ray energy range show that nevertheless part of the energy release sometimes occurs in optically thin regime. This leads to generation of hard X-ray tail in spectra of luminous neutron stars. Among different physical mechanisms under discussion are Comptonization on thermal and non thermal population of electrons on bulk motion of matter in the accretion flow synchrotron emission of relativistic electrons. Scorpius X-1 is the brightest accretion powered neutron star on the sky therefore it is reasonable to validate all proposed theoretical models on data collected from this source. INTEGRAL data collected so far allowed us to obtain its spectrum at energies 20-300 keV and exclude some of the proposed models. INTEGRAL data have demonstrated that hard X-ray tail of Sco X-1 is highly variable with factor of more than 50. This means that highest statistical quality spectrum of Sco X-1 can be obtained not by averaging all of the available dataset but by collection of data during carefully selected periods of its enhanced activity. Thus the goal of our proposal is to monitor the behavior of hard X-ray emission of Sco X-1 with the aim to obtain the best statistical quality of hard X-ray part of its spectrum. Such increase of statistical quality will allow to further constrain physical models of generation of non thermal population of particles in the accretion flows. [truncated!

description: We propose to use INTEGRAL SPI and IBIS to measure gamma-ray lines and hard X-ray continua to help clarify the mechanisms nucleosynthesis and dynamics of sufficiently nearby supernovae of any type. These have always been major objectives of the INTEGRAL mission and gamma-ray line astronomy in general but are yet to be achieved with the notable exception of SN 1987A. The requested observations range from relatively short studies of continuum emission from supernova ejecta interactions with circumstellar matter to multiple observations of very nearby events as we hope to watch the ejecta unfold to reveal the radioactivity within.   We define the Target of Opportunity trigger criteria clearly for each category of event by specifying a complete list of potential host galaxies. Although there is a low probability of any of these events in a given year there is a significant chance of one or more objects meeting our criteria in the remaining years of the INTEGRAL mission.

description: The SNR RX J1713.7-3946 is part of a class of remnants dominated by synchrotron emission in X-rays and is one of the few  detected at the TeV. It is therefore an excellent target to study particle acceleration at SNR shocks. The nature of the particles producing TeV emission is still a matter of controversy. The strong similarities between X-ray and TeV images suggest a leptonic origin but the required magnetic field is quite low. On the other hand to be viable hadronic scenarios require high ambient matter density at odds the the absence of  strong thermal X-ray emission. The hard X-rays probe the electrons in the spectral cutoffs region and are therefore fundamental to understand the mechanisms of acceleration to the highest energies. Suzaku has been able to measure the integrated spectrum of the remnant but so far no detailed spectro-imagery exist for this object. We propose a 4Ms observation of RX J1713.7-3946  to map the hard X-ray emission from the remnant from 10 keV up to 50 keV and to resolve spatially the hard X-ray spectrum of the remnant. (we request a special 3x3 dithering mode allowing good JemX exposure while limiting systematics in the other instruments). This will allow a mapping of the spectral cutoffs in the shell and hopefully shed some light on the long standing problem of the origin of cosmic rays up to the knee. [truncated!

Theprimary goal of the combined observations is to characterize thecontinuum shape especially the location of any hard x-ray breakas well as search for variations in the spectrumby contrasting this observation with the three previous INTEGRAL observations. Another primary goal is to provide an early Astro-E2/INTEGRAL cross calibration of instruments utilizing a source with a simple spectral shape and low intensitywhich allows accumulation of data with a minimum of pile-up effects in Astro-E2.

description: These nearby galaxies proposed for study with INTEGRAL have been carefully selected as an intriguing set of exploratory objects which could open an important window in the context of future gamma-ray/AGN studies and are readily detectable by INTEGRAL.  Observation of these objects with INTEGRAL follows as a natural consequence of recent X-ray observations and in particular our recent survey of AGN in the hard X-ray region of the spectrum with CGRO-BATSE.  Although classified differently within the Seyfert 2LINER context and spanning the spiral and elliptical galaxy classification  they appear to exhibit many fundamentally similar characteristics when the central engine is studied at high energies. They emit hard power law spectra above ~10 keV and are highly obscured with absorption at the NH > 10E23 level. They are accreting material at a level that is considerably below their Eddington rate and as such may be subject to Advection Dominated Accretion Flow (ADAF).  This model could explain why observations of the nuclei of several nearby galaxies indicate the presence of super massive (10E6 - 10E9 M(Solar)) black holes (BH) and yet not strong AGN activity. We plan to test such models and carefully analyse the implications of our results in terms of the evolution towards normal galaxies and the composition of the cosmic diffuse gamma-ray background.

description: IGR J16318-4848 is the first source newly discovered by INTEGRAL. It is most likely a high-mass X-ray binary enshrouded by a dense envelope. The high-energy source is highly variable on time scales exceeding 15 min.A Target of Opportunity observation with XMM-Newton showed a source which is intrinsically absorbed by a high column density of 2x10^{24}/cm^2 together with strong fluorescence lines of exceptional equivalent widths whichdominated the X-ray spectrum. Since the source is variable attempts to model both the soft X-ray and hard X-ray spectrum were hampered by fact that the XMM-Newton observations were not simultaneously with any of the (short) observations performed by INTEGRAL.IGR J1631-4848 will be observed by XMM-Newton on 3 (or possibly 4) occasions as part of its AO-3 program covering  time scales from days to months. We here propose observations with INTEGRAL to be done simultaneously with XMM-Newton. This will enable us to better constrain the high-energy spectrum. This is essential to allow an unambiguous decomposition of the variability between the various spectral components.Only a few other examples of high-mass X-ray binary sources with similar spectral characteristics do exist. Also a couple of other sources discovered by INTEGRAL seem to have similar high column densities.New observations may shed therefore also more light on this apparently new class of sources as well as to the possibility of their contribution to the high-energy Galactic background radiation.

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.

title: 1440001

description: We propose a 1Ms TOO observation of a bright black-hole transient either known or unknown to follow its complete transition from hard to soft state. This transition which takes place at high flux levels encompasses marked changes in the properties of the accretion flow and it includes the time at which the ejection of an accelerating relativistic jet stops abruptly. The study of the high-energy properties during the transition is important for our understanding of accretion onto black holes and can only be accomplished with INTEGRAL. A simultaneous large multi-wavelength campaign is being organized to support the proposed observation including other X-ray satellites. The campaign will be centered around the INTEGRAL pointing. The trigger will be provided by a threshold limit in either hard or soft X-ray flux. Such a monitoring  is becoming a key goal in the community working on black-hole binaries. [truncated!

description: Cen X-4 discovered in 1969 during an outburst is at a distance of 1.2 kpc the closest neutron star low-mass X-ray binary. This X-ray transient has recently been reported - first in optical (ATels 14254 14320) then in X-rays (Swift and NICER  ATel 14303) to be significantly brightening which strongly suggests the source is going into its third outburst after more than 41 years in quiescence. We propose a Target of Opportunity monitoring of what may well be a once-in-a-lifetime event. [truncated! Please see actual data for full text]

description: Galactic gamma-ray transients are  rare events. The Fermi Gamma-ray Space Telescope Large Area Telescope so far detected ^en transient sources close to the Galactic plane during its first four years of operations. All of them were subjects of broad multi-wavelength follow-up campaigns in soft X-ray radio and optical. Sometimes they turned out to be of extragalactic origin but most of the time they are Galactic or no proper identification could be achieved.  The Galactic Fermi transients included the first detected gamma-ray Nova  Crab-nebula flares a gamma-ray binary periastron passage and an outburst of Cyg X-3. This is a resubmission of AO-8/9 accepted ToO programs to include INTEGRAL in our multi-wavelength campaign to follow up Galactic Fermi transients.  INTEGRAL can provide very valuable information which could lead to the source identification and to yield non-thermal hard-X-ray spectra which could be directly linked to the underlying high-energy emission processes seen at gamma-rays in the Fermi band. The trigger criteria are based on (1) a Fermi detection of a transient event (2) first ToO observations/or archival information at different wavelengths excluding (or strongly suggesting) that the transient source is of extragalactic origin. Depending on the (possible) nature of the source we will estimate the optimal INTEGRAL exposure and discuss this with the Project Scientist.  We have many years of hands-on INTEGRAL experience including several (accepted and new) ToO programs. The optimal exposure time for each ToO may range from 50 ks up to 400 ks. For time-allocation purposes we request four ToO triggers up to 200 ks per trigger (adding up to 800 ks)  to be executed on either four different events or more triggers on the same event if a study of time-evolution is justified.

description: LSI+61 303 is one of the few binary systems with a compact object and Be star from which unpulsed X-ray and radio as well as the high-energy gamma-ray (GeV TeV) emission has been observed. The system is also known to emitAU-scale jet which makes it a candidate for a Galactic microblazar. The system lightcurves in different energy ranges show a puzzling behaviour with the X-ray maxima shifted with respect to the radio maxima and the maximaphase shifting from orbit to orbit. The origin of the compact source (neutron star or black hole) is not known yet and neither we are sure on the energy of the electrons producing the observed X-ray emission. The goal of this proposal is to study for the first time the spectrum of the source in hard X-rays (above 50 keV) and its variability on the orbital timescale. This information along with the simultaneous observations in GeV energy band by FERMI will give us a clue to the physical processes taking place in the system and the possibility to built the emission formation model.

description: We propose here to exploit the unique hard (E > 10 keV) X-ray imaging and spectroscopic capabilities of INTEGRAL to investigate the relative contribution and occurrence of AGN and starburst activity in a flux limited sample of 22 infrared galaxies having a 60micron flux greater than 50 Jy.  After excluding the sources already observed with the BeppoSAX PDS those not visible during AO1 and those at low (|b| < 13) galactic latitude (they will enter anyway in the INTEGRAL public archive since they are in the region covered by the ``INTEGRAL Low Galactic Latitude Core Program) we are left with 5 objects.  We ask for INTEGRAL pointing observations of 100 ksec for each of these sources (priorities are specified). Measuring the hard (E > 10 keV) X-ray flux yields reliable indication of the presence of an optically-hidden AGN absorbed in soft X-rays (N_H > 10^{24} cm^{-2}) potentially contributing for most of the emitted bolometric luminosity.  It has been shown in the last few years (mainly using the BeppoSAX PDS instrument) that the hard X-rayregime is the best energy range to investigate the occurrence of AGN activity.  INTEGRAL will allow such a detailed investigation only on local objects but an improved physical knowledge of such sources and a measure of the relative contributions of stars and the AGN to the bolometric emission would be crucially informative about the nature oftheir distant high-z counterparts.We stress that measuring the hard X-ray emission for a well defined flux-limited sample will put this investigation on firm and solid statistical ground.  We can reach this goal by combining INTEGRAL data of the proposed objects with archive data (BeppoSAX and INTEGRAL). With such an extended sample our aim is to attempt through a combination of hard X-ray and IR data to quantify for the first time the relative weights of the AGN and starburst emission in the bolometricbudget.

description: One of the key problems in X-ray and Gamma-ray astronomy is to understand accretion flows in a strong gravitational field and how they are coupled with the outflows which can be a major channel for the outputof the accretion power. This applies to both Active Galactic Nuclei (AGN) where the accretion is onto supermassive black hole as well as stellar mass Galactic black holes and even neutron stars.We propose a program with INTEGRAL coupled with multiwavelength observations in order to performdeep hard X-ray observations of a recurrent black hole that is usually found in the Low Hard state: namelyGX 339-4 or XTE J1550-564. In studying several wavelength simultaneously along with the INTEGRAL bandwe hope to gain a unique insight into the coupled inflow-outflow around an accreting stellar mass black holeas never done before over such a large frequency range with very sensitive instruments.

description: We propose to observe the Be/X-ray binary system A 0535+26 in the case it presents a normal and a giant outburst monitoring the rise to the peak and the descending part of the outburst. In the case of a giant outburst one main goal will be to study the luminosity dependence of the cyclotron energy. For the first time high accuracy measurements at high luminosities of the cyclotron energy in A0535+26 will allow to test the hypothesis of a change in the height in the accretion column caused by an increase in the mass accretion rate. If the source enters a normal outburst another important goal will be to study possible magnetospheric instabilities which have recently been discovered for this source. Non-stationary accretion can be probed using INTEGRAL capabilities which will allow to monitor the cyclotron line energy to perform a precise timing analysis and to study the pulse profile evolution with time and luminosity. Recent observations of two normal outbursts with INTEGRAL have revealed new unexpected features making observations of normal outbursts extremely useful tools to study the onset of the accretion onto a neutron star at low accretion rates.
