cds-question@unistra.frastronomical-object-identificationradio-sourcessurveysWe present the results of an extragalactic point source search using the five-year Wilkinson Microwave Anisotropy Probe (WMAP) 41, 61, and 94GHz (Q, V, and W bands) temperature maps. This work is an extension of our designing and applying a cosmic microwave background (CMB)-free technique to extract point sources in the WMAP maps. Specifically, we have formed an internal linear combination map of the three-band maps, with the weights chosen to remove the CMB anisotropy signal as well as to favor the selection of flat-spectrum sources. We have also constructed a filter to recover the true point source flux distribution on the sky. A total of 381 sources are found in our study at the >5{sigma} level outside the WMAP point source detection mask, among which 89 are "new" (i.e., not present in the WMAP catalogs). Source fluxes have been calculated and corrected for the Eddington bias. We have solidly identified 367 (96.3%) of our sources, the 1{sigma} positional uncertainty of which is 2'. The 14 unidentified sources could be either extended radio structure or obscured by Galactic emission. We have also applied the same detection approach to simulated maps, which yielded 364+/-21 detections on average. The recovered source distribution N(>S) agrees well with the simulation input, which proves the reliability of this method.2009ApJ...694..222Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/694/222CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/40 : GB6 catalog of radio sources (Gregory+ 1996)VIII/38 : The Parkes-MIT-NRAO 4.85GHz (PMN) Surveys (Griffith+ 1993-1996)VIII/5 : Bright Extragalactic Radio Sources (1Jy) (Kuehr+, 1981)J/ApJS/180/283 : WMAP source catalog (Wright+, 2009)J/A+A/508/107 : WMAP3 catalogue (Giommi+, 2009)J/MNRAS/392/733 : The NEWPS catalog from WMAP 5-yr survey (Massardi+, 2009)J/MNRAS/384/775 : Bright Source Sample of AT20G Survey (Massardi+, 2008)J/AZh/85/483 : Sources from the WMAP catalog (Vol'vach+, 2008)J/ApJ/681/747 : Extragalactic point-source WMAP catalog (Chen+, 2008)J/ApJS/171/61 : All-Sky Survey of Flat-Spectrum Radio Sources (Healey+, 2007)J/ApJS/148/97 : The WMAP First Year Source Catalog (WMAP1) (Bennett+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/694/222https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/694/222http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/694/222https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/694/222https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/694/222http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/694/222GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/694/222/table1 (Identified point sources from five-year Q-, V-, and W-band ILC (internal linear combination) map)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/694/222/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/694/222/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/694/222/table1?GETtext/xml+votable180.050000true1.5542-6.40.005555555555555556Cone search capability for table J/ApJ/694/222/table2 (Unidentified point sources from five-year Q-, V-, and W-band ILC (internal linear combination) map)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/694/222/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/694/222/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/694/222/table2?GETtext/xml+votable180.050000true59.654222.60.0055555555555555566/18 110 180 438 464 532 556 579 700 911 967 1154 1497 1701 2143 2220 2245 2414 2564 2721 2836 2867 3537 3918 4285 4572 4695 4770 4820 5139 5154 5448 5458 5597 5693 5767 5806 5817 5848 6164 6252 6496 6641 6853 6948 6984 6996 7346 7389 7394 7426 7570 7606 7653 7709 7851 7896 7911 7969 8031 8057 8299 8485 8717 8773 8858 9403 9442 9460 9545 9588 9612 9633 9636 9670 9688 9722 9723 9899 9976 9998 10166 10249 10422 10426 10432 10548 10986 11067 11430 11631 11639 11640 11715 11880 12047 12167 12241 12301 12352 12444 12580 12599 12604 12619 12752 13177 13273 13320 13352 13410 13496 13582 13659 13693 13722 13789 13792 13855 13871 14150 14520 14537 14843 14854 14858 14916 15023 15067 15146 15174 15207 15286 15525 15916 15936 15973 16027 16049 16057 16059 16093 16113 16170 16281 16298 16301 16655 16676 16962 17019 17048 17184 17351 17414 17541 17978 18005 18035 18365 18378 18504 18624 18661 18669 18718 19088 19101 19190 19398 19567 19622 19890 20099 20213 20290 20476 20607 20610 20657 20725 20784 20787 20797 20881 20888 21121 21215 21266 21768 21873 21924 21935 21960 21968 22100 22305 22363 22375 22396 22632 22658 22659 22828 22917 22950 23099 23121 23127 23215 23304 23306 23323 23364 23383 23436 23469 23882 24608 24775 24796 24845 25016 25196 25255 25256 25302 25630 25647 25677 25864 26036 26131 26292 26303 26374 26543 27060 27310 27322 27417 27423 27714 27765 28167 28454 28479 31190 31334 31389 31399 31430 31451 31509 31559 31664 31986 32131 32247 32311 32660 32764 32841 32918 32961 33549 33560 33684 33825 33827 33862 33881 34013 34038 34104 34123 34210 34264 34428 34463 34494 34517 34571 34572 34675 34870 34871 35078 35294 35440 35501 35562 35801 36100 36139 36155 36178 36295 36333 36554 36785 36863 36941 37040 37385 37474 38128 38189 38277 38663 38761 38916 39639 39659 39848 40060 40360 40474 40527 40533 40777 41041 41051 41059 41072 41241 41310 41325 41335 42060 43366 43531 43549 43806 43822 43936 44170 44247 44805 44899 44908 45011 45111 45164 45409 45446 45614 45774 45823 46055 46101 46174 46204 46214 46251 46310 46337 46384 46404 46764 46964 47016 47106 47107 47154 47185 47268 47375 47534 47540 48023 48123 48344 48496 48595 48610 48798 48846 489652.716688523826284e-23 6.228505396089529e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/694/222?format=asciiRadiodefaultJ/ApJ/694/222/table1Identified point sources from five-year Q-, V-, and W-band ILC (internal linear combination) maprecnoRecord number assigned by the VizieR team.
