Present PositionLeader US INTEGRAL Guest Observer FacilityResearch Assistant Professor University of Maryland, Baltimore County INTEGRAL project Brief BioDr. Beckmann's PhD thesis was on luminosity function of blazars and Seyfert 2 galaxies. After starting to work for the INTEGRAL Science Data Centre in Geneva (Switzerland) as a specialist for the INTEGRAL/SPI software, he also became involved in other fields than AGN, such as X-ray binary systems and Gamma-ray bursts. Since October 2003 he is working for the University of Maryland Baltimore County (UMBC) at NASA GSFC. Since July 2004 he is also teaching at UMBC, for example Stellar Astrophysics (fall 2004) and Cosmology (fall 2006). Since July 2006 he is the head of the US INTEGRAL Guest Observer Facility at GSFC, and since August 2006 research assistant professor at UMBC.Educational BackgroundMaster Physics, University of Hamburg (1996): "X-ray spectral slope of AGN in the ROSAT All Sky Survey"Ph.D., Astrophysics, University of Hamburg - Hamburg Observatory (2001): "Evolutionary behaviour of AGN: Investigations on BL Lac objects and Seyfert II galaxies" Research InterestsHigh energy astrophysics, X-rays and Gamma-ray spectroscopyActive Galactic Nuclei, luminosity function, high-energy spectrum, radiation processes X-ray binaries, absorbed Galactic sources Gamma-ray bursts Current ProjectsINTEGRAL AGN studies:Beckmann, Gehrels, Shrader and Soldi have completed recently the first INTEGRAL AGN catalog, based on 1.5 years of INTEGRAL's hard X-ray data. A paper describing the first luminosity function of AGN in the 20-40 keV band has been accpeted for publication in ApJ and will be reported on the "Extragalactic Surveys" workshop in Cambridge (Massachusetts) in November 2006. X-ray binaries, absorbed Galactic sources: In a combined study of INTEGRAL, Swift and RXTE, Beckmann et al. have found a highly absorbed HMXB containing a neutron star. The object is one of only 7 of its kind know so far. The article about the source IGR J16283-4838 has been published in ApJ. INTEGRAL high level archive: Together with the INTEGRAL GOF team Beckmann creates a high level archive of INTEGRAL results, available through the HEASARC system. This includes results of observations such as maps, lightcurves, and spectra and the INTEGRAL Bright Source Catalog.
