ABSTRACT We present a catalog of high-energy gamma-ray sources detected by the Large Area Telescope (LAT), primary science instrument on Fermi Gamma-ray Space (Fermi) , during first 11 months phase mission, which began 2008 August 4. The First -LAT (1FGL) contains 1451 and characterized in 100 MeV to GeV range. Source detection was based average flux over month period, threshold likelihood Test Statistic is 25, corresponding significance just 4σ. 1FGL includes source location regions,...
We present the second catalog of high-energy gamma-ray sources detected by Large Area Telescope (LAT), primary science instrument on Fermi Gamma-ray Space (Fermi), derived from data taken during first 24 months phase mission, which began 2008 August 4. Source detection is based average flux over 24-month period. The Second Fermi-LAT (2FGL) includes source location regions, defined in terms elliptical fits to 95% confidence regions and spectral power-law, exponentially cutoff or log-normal...
The well known Crab Nebula is at the center of SN1054 supernova remnant. It consists a rotationally-powered pulsar interacting with surrounding nebula through relativistic particle wind. emissions originating from and have been considered to be essentially stable. Here we report detection strong gamma-ray (100 MeV-10 GeV) flares observed by AGILE satellite in September, 2010 October, 2007. In both cases, unpulsed flux increased factor 3 compared non-flaring flux. flare luminosity short...
We present a catalog of gamma-ray sources at energies above 10 GeV based on data from the Large Area Telescope (LAT) accumulated during first three years Fermi Gamma-ray Space mission. The Fermi-LAT >10GeV (1FHL) has 514 sources. For each source we location, spectrum, measure variability, and associations with cataloged other wavelengths. found that 449 (87%) could be associated known sources, which 393 (76% 1FHL sources) are active galactic nuclei. Of 27 pulsars, find 20 (12) to have...
eXTP is a science mission designed to study the state of matter under extreme conditions density, gravity and magnetism. Primary goals are determination equation at supra-nuclear measurement QED effects in highly magnetized star, accretion strong-field regime gravity. targets include isolated binary neutron stars, strong magnetic field systems like magnetars, stellar-mass supermassive black holes. The carries unique unprecedented suite state-of-the-art scientific instruments enabling for...
Abstract An overview is presented of the progress since 2021 in construction and scientific programme preparation Divertor Tokamak Test (DTT) facility. Licensing for building has been granted at end 2021. Cat. A radiologic source also 2022. The toroidal field magnet system progressing. prototype 170 GHz gyrotron produced it now under test on FALCON design vacuum vessel, poloidal coils civil infrastructures completed. shape first DTT divertor agreed with EUROfusion to different plasma exhaust...
We present the characteristics of 308 terrestrial gamma ray flashes (TGFs) detected by Minicalorimeter (MCAL) instrument on board AGILE satellite during period March 2009–July 2012 in ±2.5° latitude band and selected to have maximum photon energy up 30 MeV. The events are analyzed compared observational framework established two other currently active missions capable detecting TGFs from space, RHESSI Fermi. A detailed model MCAL dead time is presented, which fundamental properly interpret...
We present two catalogs of radio-loud candidate blazars whose WISE mid-infrared colors are selected to be consistent with the confirmed gamma-ray emitting blazars. The first catalog is improved and expanded release WIBRaLS presented by D'Abrusco et al. (2014): it includes sources detected in all four filters, spatially cross-matched radio source one three surveys based on their q22 spectral parameter. WIBRaLS2 9541 classified as BL Lacs, FSRQs or mixed candidates colors. second catalog,...
The efficient detection of low-energy X-rays at the keV level with best possible energy resolution requires application silicon drift detectors (SDDs) and advanced specific integrated circuits (ASICs). Their widespread use in material sciences, alongside dedicated basic science projects, has long been restricted to single, selected SDD elements working low temperatures. This is because limits incurring quite elaborated planar technology production process need reach very leakage current...
At the end of March 2015 onboard software configuration AGILE satellite was modified in order to disable veto signal anticoincidence shield for minicalorimeter instrument. The motivation such a change understanding that dead time induced by prevented detection large fraction Terrestrial Gamma-Ray Flashes (TGFs). highly successful resulting an increase one magnitude TGF rate. As expected, largest new events has short duration ($< 100 \mathrm {\mu s}$), and part them simultaneous association...
The Large Observatory For x-ray Timing (LOFT) was studied within ESA M3 Cosmic Vision framework and participated in the final down-selection for a launch slot 2022-2024. Thanks to unprecedented combination of effective area spectral resolution its main instrument, LOFT will study behaviour matter under extreme conditions, such as strong gravitational field innermost regions accretion flows close black holes neutron stars, supra-nuclear densities interior stars. science payload is based on...
