cds-question@unistra.fractive-galactic-nucleibl-lacertae-objectsgamma-ray-astronomygalaxiesWe present the 1-100GeV spectral energy distribution (SED) for a population of 148 high-synchrotron-peaked (HSP) blazars recently detected with Fermi-LAT as part of the First Brazil-ICRANet Gamma-ray Blazar (1BIGB) catalogue. Most of the 1BIGB sources have their {gamma}-ray spectral properties presented here for the first time, representing a significant new extension of the {gamma}-ray blazar population. Since our sample was originally selected from an excess signal in the 0.3-500GeV band, the sources stand out as promising TeV blazar candidates, potentially in reach of the forthcoming very high energy (VHE) {gamma}-ray observatory, Cherenkov Telescope Array (CTA). The flux estimates presented here are derived considering PASS8 data, integrating over more than 9yr of Fermi-LAT observations. We also review the full broad-band fit between 0.3 and 500GeV presented in the original 1BIGB paper for all sources, updating the power-law parameters with currently available Fermi-LAT data set. The importance of these sources in the context of VHE population studies with both current instruments and the future CTA is evaluated. To do so, we select a subsample of 1BIGB sources and extrapolate their {gamma}-ray SEDs to the highest energies, properly accounting for absorption due to the extragalactic background light. We compare those extrapolations to the published CTA sensitivity curves and estimate their detectability by CTA. Two notable sources from our sample, namely 1BIGBJ224910.6-130002 and 1BIGBJ194356.2+211821, are discussed in greater detail. All {gamma}-ray SEDs are made publicly available via the Brazilian Science Data Center (BSDC) service, maintained at CBPF, in Rio de Janeiro.2018MNRAS.480.2165Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/480/2165CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/598/A134 : {gamma}-ray signature in WHSP blazars (1BIGB) (Arsioli+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/480/2165https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/480/2165http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/480/2165https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/480/2165https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/480/2165http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/480/2165GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/480/2165/tablea1 (Table showing the 148 1BIGB {gamma}-ray signatures)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/480/2165/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/480/2165/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/480/2165/tablea1?GETtext/xml+votable180.050000true2.45708-43.280560.0055555555555555566/29 49 115 137 717 975 1704 2249 3351 4040 4098 4190 4642 4672 4705 4974 5657 5939 6204 6362 7265 7613 7681 8008 8134 8258 8267 8374 9168 9383 9694 9860 9991 10154 10258 10756 10766 10852 11321 11572 11778 12433 12973 13534 13546 14962 16015 16740 17188 17519 17721 17820 18498 18513 18760 18992 19034 19405 19558 19786 19870 20438 20546 20670 20696 20888 20918 21454 22608 22611 23085 23208 23231 23516 24737 25187 25203 25209 25510 25849 26134 26176 26248 26569 26571 26787 26986 27021 27053 27631 27722 28432 29313 30894 31177 31318 31636 31679 32244 32344 32442 32990 33606 33609 34214 34250 34285 34420 34464 34617 34721 34759 35311 35356 35489 35630 35905 36366 36779 37523 38389 39012 40351 40809 41155 41187 41966 43421 43630 44289-44290 44379 44474 44477 44533 44820 45016 45214 45543 45812 46090 46918 46924 48090 48504 48629https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/480/2165?format=asciiGamma-raydefaultJ/MNRAS/480/2165/tablea1Table showing the 148 1BIGB {gamma}-ray signaturesSimbadNameSimbad column added by the CDSmeta.idcharnullableDEJ2000Declination (J2000)degpos.eq.dec;meta.mainz?
