TeV Signatures of Fermi and IACT Sources Observed by Milagro
Abstract
We perform targeted searches in Milagro data to detect TeV emissions from potential TeV-emitting candidates. Galactic candidates were GeV pulsars from the Fermi LAT second source catalog (2FGL) in the Milagro sky coverage (-7°< DEC < 80° ). Extragalactic candidates are selected from the 2FGL and from the Imaging Air Cerenkov Telescope (IACT) detections in the TeVCat catalog. Out of 52 pulsar targets, emission in the 1-100 TeV energy range is found coincident with 15 of them. We studied the TeV-GeV flux correlation of these observations. Among 709 extragalactic observations Markarian 421 was indentified with a high statistical significance and three other AGNs were identified as potential TeV emitting sources with a flux just below our sensitivity threshold. Our measurements and comparisons of results with existing models will be presented in this talk.
