2 INTEGRAL: International Gamma-Ray Astrophysics Laboratory The payload The mission The project
3 IBIS (Imager on-board the Integral Satellite) high resolution images of celestial objects of all classes. 15keV 10MeV. ISGRI // PICsIT FOV ~ 8º x 8º JEM-X (Join European Monitor for X-rays) 3 35 kev Images FOV: 5º radius circle INTEGRAL spectra of Galactic Bulge sources. INTEGRAL payload SPI (Spectrometer on Integral) OMC (Optical Monitoring Camera)
4 Observation of various gamma-ray phenomena by combining fine spectroscopy with imaging and accurate positioning of celestial sources of gamma-ray emission. Science objectives: INTEGRAL Compact objects (White Dwarfs, Neutron Stars, Black Hole Candidates, High Energy Transients and Gamma-Ray Bursts) Extragalactic astronomy (Galaxies, Clusters, AGN, Seyferts, Blazars, Cosmic Diffuse Background) Stellar nucleosynthesis (Hydrostatic Nucleosynthesis (AGB, WR Stars), Explosive Nucleosynthesis (Supernovae, Novae)) Galactic plane and centre structure (Cloud Complex Regions, Mapping of continuum and line emission, ISM, CR distribution) Particle processes acceleration (Transrelativistic Pair Plasmas, Beams, Jets) Identification of high energy sources (Unidentified Gamma-Ray Objects as a Class)
5 The INTEGRAL Galactic Bulge monitoring program Observe the region frequently and regularly investigate the source variability and transient activity on time scales of days to weeks and months relatively soft and hard energies Get the data of IBIS/ISGRI and JEM-X fit to standard models: powerlaw & cutoffpowerlaw -Have we missed something? plot the parameters with time (revolutions) - Global properties of the sources - Are there spectral changes?
6 Why IBIS/ISGRI & JEM-X? Revolutions MJD , 2005/02/ /04/21 IBIS/ISGRI 20-60keV Mosaic All the sources Galactic center SPI: bad resolution OMC: too many stars (optical!!) (2.5º) (IBIS: Angular resolution: 12arcmin)
7 Obtaining the data IBIS/ISGRI 81 sources 10 hours JEM-X 12 more significant sources 1 hour
8 Data treatment Cleaning for IBIS/ISGRI Collecting the sources get images, spectra & light curves Binning for JEM-X Fitting with XSPEC: (PROGRAM) Fitting IBIS/ISGRI & JEM-X independently Fitting IBIS/ISGRI & JEM-X together Parameters in each revolution
9 The models: Powerlaw: par1 = Γ norm= N photon index of power law (dimensionless) photons kev 1 cm 2 s 1 at 1 kev Cutoffpl: power law, high energy exponential cutoff par1 = Γ power law photon index par2 = β e-folding energy of exponential rolloff (in kev) norm = N Photons kev -1 cm -2 s -1 at 1 kev

12 What the program does: Ignores the bad energies: compromise Fits the models (adding a constant when we have both detectors) Asks for the detection significance Plots the fitted spectra and saves them Saves the fittings Saves the parameters and errors for each source and model Do tables per source or per revolution
