Monitoring the Northern Sky for Sources of TeV Gamma Rays

At the present time there are fewer then 10 confirmed sources of TeV gamma rays. While this lack of sources is partially due to the sensitivity of current instruments, it may also be due to the small field-of-view of current instruments coupled with the transient nature of astrophysical sources of TeV gamma rays. Milagro is a new type of extensive air shower array that uses water as the detecting medium and has the ability to continuously monitor the entire overhead sky for transient and steady sources of TeV gamma rays. Here the analysis of 2.4 years of data searching for steady TeV gamma-ray emission in the northern hemisphere is presented. Two sources have been detected: the Crab nebula and Mrk 421. A third region at a location of 79.44±1.0 ra and 26.26±0.7 declination is the third brightest region in the northern sky. After accounting for the trials associated with searching the entire northern hemisphere this region is not statistically significant. At the conference results from searches for transient emission on timescales of 1 week and greater will be presented.
