The main result is that only a minuscule part of the more than 720 sources detected by INTEGRAL and the population of 205 Fermi LAT sources are detected in both spectral regimes. This is in spite of the mCrab INTEGRAL sensitivity for both galactic and extragalactic sources and the breakthrough, in terms of sensitivity, achieved by Fermi at MeV-GeV energies. The majority of the 14 Fermi LAT sources clearly detected in the fourth INTEGRAL/IBIS catalog are optically identified active galactic nuclei (10) complemented by two isolated pulsars (Crab and Vela) and two high-mass X-ray binaries (LS I +61 303 and LS 5039). Two more possible associations have been found: one is 0FGL J1045.6-5937, possibly the counterpart at high energy of the massive colliding wind binary system Eta Carinae, discovered to be a soft gamma ray emitter by recent INTEGRAL observations and 0FGL J1746.0-2900 coincident with IGR J17459-2902, but still not identified with any known object at lower energy. For the remaining 189 Fermi LAT sources no INTEGRAL counterpart was found and we report the 2{sigma} upper limit in the energy band 20-40keV.2009ApJ...706L...7Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/706/L7CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/715/429 : First Fermi-LAT AGN catalog (1LAC) (Abdo+, 2010)J/ApJS/188/405 : Fermi-LAT first source catalog (1FGL) (Abdo+, 2010)J/ApJS/186/1 : The 4th IBIS/ISGRI soft gamma-ray survey catalog (Bird+, 2010)J/A+A/523/A61 : INTEGRAL all-sky survey of hard X-ray sources (Krivonos+,J/ApJS/183/46 : Fermi/LAT bright gamma-ray source list (0FGL) (Abdo+, 2009)J/A+A/505/417 : Second INTEGRAL AGN catalogue (Beckmann+, 2009)J/ApJ/700/597 : FERMI LAT detected blazars (Abdo+, 2009)J/A+A/484/783 : Spectroscopy of 7 INTEGRAL X-ray sources (Chaty+, 2008)J/A+A/467/585 : Sources detected by ISGRI (Bodaghee+, 2007)J/ApJ/607/L33 : First IBIS Catalog: 20-100keV (Bird+, 2004)J/A+A/411/L59 : INTEGRAL reference catalog (Ebisawa+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/706/L7https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/706/L7http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/706/L7https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/706/L7https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/706/L7http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/706/L7GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/706/L7/table1 (Spatial correlation between Fermi LAT and IBIS sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/706/L7/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/706/L7/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/706/L7/table1?GETtext/xml+votable180.050000true187.27789642.05240640.005555555555555556Cone search capability for table J/ApJ/706/L7/table2 (2{sigma} upper limit (20-40keV) for the 189 Fermi LAT sources with no IBIS counterpart)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/706/L7/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/706/L7/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/706/L7/table2?GETtext/xml+votable180.050000true1.642573.18516670.0055555555555555566/579 911 1199 1701 2122 2295 2331 2414 2836 3023 3308 3431 3819 4695 4770 5162 5423 5817 5918 6018 6088 6368 6507 6777 6963 7045 7346 7426 7446 7896 8299 8466 8915 9075 9460 9612 9632 10422 11081 11153 11212 11649 12604 12619 13106 13465 13485 13664 13750 13927 14413 14424 14454 14608 14619 14690 14692 14751 14854 15310 15376 15644 15969 16027 16298 16720 16796 17186 17341 17364 17579 17857 17927 18153 18315 18624 19370 19398 19622 19831 20099 20552 21121 21564 22154 22255 22271 23121 23646 23897 23952 23995 24084 24185 24608 24845 25065 25302 25677 25818 26131 26292 27060 27243 27310 27433 28342 28479 28492 28517 28673 28814 28824 28830 28893 28913 28919 29016 29072 29101 29119 29162 29261 29471 29505 29532 30193 30218 30244 30258 30263 30319 30417 30446 30593 30616 30694 31116 31663 31894 32311 33094 33321 33774 33825 33964 34123 34209 34428 34461 34572 35079 35281 35706 35786 36058 36151 36554 36941 37215 37341-37343 37529 37829 37923-37924 38016 38020 38081 39235 40479 41598 41685 41743 41758 41857 41937 42171 42173 42206 42215 42384 42444 42515 42530 42980-42981 43085 43122 43262 43822 44069 44247 44908 45011 46055 46237 46251 46740 47014 47375 48123 48193 49071https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/706/L7?format=asciiGamma-rayRadiodefaultJ/ApJ/706/L7/table1Spatial correlation between Fermi LAT and IBIS sourcesrecnoRecord number assigned by the VizieR team.
