description: GRS 1915+105 is one of the most enigmatic objects in our Galaxy. Classified as a black hole candidate it exhibits extreme variability at all wavelengths. We propose to observe GRS 1915+105 exploiting the X- and gamma-ray instruments onboard INTEGRAL. Our main goal is to obtain time-resolved hard X-ray spectra of the fundamental states of GRS 1915+105 in order to fix the origin of the hard tail - as seen by IBIS and SPI - and thus enable us to test three models: Comptonization by thermal nonthermal or free-fall electrons. JEM-X will allow us to discriminate between spectral states in the course of each observation. In additino we expect to explore the rapid variability (QPOs) at both low and high energies and study possible annihilation line features.We request that our observations be undertaken in segments of 100 ksec exposures. We require ten such segments separated by approximately one month compatible with scheduling for the full scientific case.  We are aware that GRS 1915+105 is an important target of the Core Program and as such will be observed quite thoroughly. However our data will be complementary to those obtained during the Galactic Plane Scans and possible ToO follow-ups. We shall accumulate more exposure time than during the cumulative Galactic Plane Scans which will  enable us to do very detailed spectral modeling. By observing GRS 1915+105 for 100ks at approximately monthly intervals we can expect to investigate the source in its various states. As we primarily want to investigate these different states we do not necessarily need to observe the source when it fulfills the ToO criteria. ToO observations alone are not sufficient for our goals but they are complementary. In addition we are in a position to provide simultaneous radio and infrared observations and thus maximize the opportunity of observing possible ejection events or the signatures thereof during the INTEGRAL observations  [truncated!

description: We propose to monitor NGC 4151 with INTEGRAL to accurately and simultaneously measure the spectral shape up to above 200 keV and to study large amplitude variations with an unprecedented sensitivity and time coverage at high energy. We will correlate the high energy spectral cutoff with other continuum parameters to confirm thermal comptonisation and determine the main physical mechanism driving the variability. We will also disentangle the reflection hump and its variations from the primary continuum and intrinsic absorption 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 which will constrain the electrons acceleration mechanisms. We request 2 observations of 400 ksec eachto continue the monitoring program started in AO4. [truncated! Please see actual data for full text]

The aim of this proposal is toperform a detailed study of Compton thick X-ray absorption in neutral or weakly ionized material. We willsearch for the curvature in the continuum above 10 keV caused by Compton downscattering in the absorber.The INTEGRAL data will also be important for the Fe line study with Astro E2 by allowing us to determine theshape of the continuum responsible for the fluorescence.

description: While GRB afterglows are observed in an exceptionally broad range of photon energies an observation in the hard X-ray to soft gamma-ray range is very rarely available.  Part ofthe reason for this consists in limited fields of view of the hard X-ray instruments as well asdifficulty in implementation of very rapid follow-up strategies required for detection of therapidly fading afterglow.Small  number  of  hard  X-ray  afterglow  detections  make  it  difficult  tomake detailedpredictions for expectations of INTEGRAL follow-up of neutrino and gravita-tional wave transients which are thought to be associated with nearby GRBs.Additionally detection of the GRB afterglow in previously poorly explored energy range would  provide  new  important  information  allowing  approach  consistent  understanding  ofthe complex interaction between ultra-relativistic ejecta of the GRB and the circum-burstenvironment.Finally the target of this proposal will serve as a live and practical test for the newly understood unique capacity of INTEGRAL to perform very fast slews which has a potential to provide unique early hard X-ray observations with its large FoV as demonstrated in the case of GW170817 re-pointing.We suggest to perform INTEGRAL pointed follow-up of exceptionally bright and luminous GRBs.Taking into account difficulty of rapid follow-up we only request observation inthe most favourable conditions when it is technically feasible to to start the ToO very soon after the event.

description: The  study of hard X-ray emission (i.e. energy above 20 keV) of Seyfert galaxies is a powerful tool for extracting information on the intrinsic source emission properties as luminosity and spectral shape  of the sources and on the intervening medium. Observations and measurements are fundamental for the study and understanding of the emission mechanisms operating in this type of objects and for testing unified models.At lower energies we can obtain information on column densities ionization and abundances of the surrounding matter which probe the environment around the central engine.We require one observation of 300 ks of the brightest Seyfert 2 galaxy NGC 4945. This observation will provide a good detection of the high energy spectra of NGC 4945  as well as  Cen A and NGC 4507 present in its field of view allowing us precise spectral (primary power law reflection cutoff) and variability studies of these three bright Seyfert 2 galaxies.

description: The Galactic Bulge region is a rich host of variable high-energyX-ray and gamma-ray point sources. In AO-3 there is much less focus on this interesting region within the Core Program. Because of the high scientific return and to preserve the continuity with respect to past observations of this ever-changing region we suggest to cover this gap in the observing program. Our approach however has some new appealing facets. We propose to observe the region more frequently and regularly than before i.e. during the entire visibility periods we suggest to do a single hexagonal dither observation per INTEGRAL revolution. As a service to the scientific community we want to make the IBIS/ISGRI and JEM-X light curves both in two energy bands per science window (i.e. per individual exposure of the hexagonal) and per hexagonal observation publicly available through the web as soon as the observations have been performed. Any new source which emerges from our observation will be announced promptly so that rapid follow-up by the communityis possible. Our team consists of scientists with expertise on a large range of topics. We intend to do a more in-depth analysis (spectra timing etc.) of sources of particular interest on short and long time scales. These sources include bright and relatively faint X-ray transients X-ray bursters persistent neutron star and black-hole candidate binarieshigh-mass X-ray binaries etc.. [truncated!

description: We propose a 500 ks target of opportunity INTEGRAL observation of a blazar in outburst as detected by the FACT blazar-monitoring program at TeV energies supplemented by pre-outburst snapshots and follow-up monitoring with Swift. Bright TeV gamma-ray flares have been detected frequently from blazars such as Mrk 501 Mrk 421 and 1 ES 1959+650 but time-resolved information of the multiwavelength spectra covering the complete outburst are rare. Leptonic models for TeV flares predict simultaneous flux increases in the X-ray and in the gamma-ray band while lepto-hadronic models show a complex variability pattern in these energy bands depending on the dominant process responsible for the gamma-ray emission. Other types of TeV flares challenge current models: orphan flares which show variability in gamma-rays only and flares with time lags between both bands. Most existing data sets of flaring behaviors lack detailed pre- and post-flare light curves and spectra as well as continuous TeV monitoring. The here proposed observations 1) are triggered on bright gamma-ray flares 2) yield simultaneous data in the optical/UV X-ray GeV- and very-high gamma-ray bands and 3) contain pre- and post-flare source state information. This type of ToO observations are feasible with the FACT blazar-monitoring program. [truncated! Please see actual data for full text]

description: We propose a 200 ks INTEGRAL observation of the ultraluminous infrared galaxy (ULIG) Mrk 273.  Due to the penetrating power of gamma rays INTEGRAL observations can determine whether the luminous infrared emission in Mrk 273 originates from a buried AGN with important implications for theories of galaxy evolution and the relationship between quasars disturbed galaxies and normal galaxies.  the INTEGRAL results will also be important for determining the contribution of infrared luminous glaxies to the soft X-ray and gamma-ray background.

description: We propose a 600 ksec INTEGRAL observation of the gamma-ray blazar 3C 279 simultaneous with XMM-Newton and GLAST/LAT. The main goal is to measure its hard X-ray properties (spectrum variability) in correlation to simultaneous high-energy observations at X- and gamma-ray energies which are guaranteed by an approved XMM-Netwon proposal and by GLAST (assuming proper operation then). These high-energy data of unprecedented sensitivity and energy coverage will be supplemented by ground-based measurements adding finally up to multifrequency spectra of unprecedented accuracy and spectral extent i.e. up to hundreds of GeV. Such high-quality SEDs will provide severe constraints on their modelling and therefore have the potential to discriminate among emission models. Because the observed radiation of 3C 279 is almost purely of non-thermal origin we are studying jet physics including the physics of particle acceleration. [truncated!

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: ToO on the new pulsar SXP 175 discovered in SMCAs part of our regular monitoring of the Bar in the Small Magellanic Cloud (SMC) with RXTE we have just detected a new pulsar with a period of 175 s which we have designated as SXP 175. Because of the large field of view (FOV) of the PCA we are unable to locate this object to better than ~1 degree. We there need to take advantage of the unique INTEGRAL science capability to locate this object to a few arcmins and thereby trigger a Swift or XMM follow-up to locate this object. This technique has proved itself to be hugely successful during our INTEGRAL/SMC observing campaign of 2009 and led to the identification of several new sources - all of which have since been published. The key role that only INTEGRAL can play is to reduce the positional uncertainty down from the unmanageable ~1 degree to the few arcmins which permits identification. Once we have an X-ray position then we can immediately tap into the wealth of optical  and  IR data available for SMC systems and greatly enhance the science returns for this new object. We realise now that this INTEGRAL stepping-stone is crucial in maximising our science. Using WebPIMMS and the Integral Observation Time Estimator we predict a 22sigma detection from a 100ks INTEGRAL observation. [truncated! Please see actual data for full text]

description: We propose a 100ks TOO observation of the transient Black-Hole candidate GX 339-4 in its short-lived Very-High State with the aim to investigate the nature of its hard component. For this component in the Very High State of other Black-Hole Candidates there has been no high-energy cutoff measured pointing towards the presence of non-thermal plasma but the complete picture from spectra and timing is inconsistent. We will be able to establish the presence/absence of such a cutoff with high confidence to determine the shape of the broad-band spectrum and to detect a possible 511 keV line. The trigger will be provided either by RXTE or by Swift. A simultaneous RXTE and radio campaign will be arranged. [truncated! Please see actual data for full text]

description: The Large  and  Small Magellanic Clouds (LMC  and  SMC) represent an exceptional opportunity to study the evolution of X-ray binaries (XRB) under very di erent conditions to that in the Milky Way. The Clouds are close enough for the individual sources to be detected identi ed  and  studied whilst presenting diverse environments in terms of metallicity and tidal e ects. A recent Key Programme covering the SMC is producing a wealth of data on persistent and transient systems plus revealing strong evidence for the emergence of a previously-unknown XRB population in the western Bridge (the structure linking the LMC to the SMC). In this proposal we request a 2Ms Key Programme to investigate the LMC and the eastern end of the Bridge to a similar depth. Such a programme which will entail both the monitoring of transient sources and a search for a faint persistent population enables us to explore stellar and binary evolution in di erent chemical and tidal environments.

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://isa.gcsu.edu) 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: Monitoring of microquasars such as GRS 1915+105 and Cygnus X-1 during the previous INTEGRAL AOs has revealed a wealth of new observational information. The monitoring has revealed the dynamical behavior of these sources above 20 keV on all timescales as opposed to the snapshot observations available before. We propose to continue the monitoring of these canonical black holes with a dedicated Key Programme in INTEGRAL AO7 which will also include the soft X-rays through a strategy that allows the source to remain in the field of view of JEM-X. The proposed investigation will allow to study di erent emission models for the two extreme cases of microquasars with INTEGRAL and simultaneous optical IR and radio observations. This proposal is a continuation of our earlier accepted observations that started in AO1. [truncated! Please see actual data for full text]

description: INTEGRAL observations of SRGA J043520.9+552226In the spring of this year SRG/ART-XC detected a new hard X-ray transient SRGA J043520.9+552226 associated with a slowly varying optical transient AT2019wey. A week days ago SRG observed this source for the second time in the course of its all-sky survey and found it to be even brighter at a flux of ~5e-10 ergs/cm2/s.During the April-September this source was extensively monitored by different X-ray (Swift/NICER/NuSTAR/Chandra) observatories along with optical and radio observations. There are different clues that indicate that the SRGA J043520.9+552226 is an accreting XB in our Galaxy.Three NuSTAR observations made after our discovery shown that the source spectrum is hard with powerlaw slope of 1.8-2 and no obvious cut-off at high energies. Two of these observations happened in the late August the 30-60 keV flux was about 40 mCrab.We are planning to utilize a break from all-sky survey on Oct 5 caused by a correction of the SRG orbit in order to perform anobservation of this source. Currently we have scheduled this observation to happen on 2020-10-05 20:40:00 - 2020-10-06 00:00:00 UTC but we will try to expand it. We are asking INTEGRAL to join this observation pursuing two main tasks: first we would like to obtain a set of simultaneous observations with ART-XC JEM-X and IBIS in order to perform cross-calibration second we would like to use INTEGRAL data to measure the spectral shape at high energies (above 80 keV).
