Abstract

We report on observations of the sky region around the unidentified TeV γ-ray source (TeV J2032+4130) carried out with the Whipple Observatory 10m atmospheric Cerenkov telescope for a total of 65.5 hr between 2003 and 2005. The standard two-dimensional analysis developed by the Whipple collaboration for a stand-alone telescope reveals an excess in the field of view at a pretrial significance level of 6.1 σ. The measured position of this excess is α = 20h32m27s, δ = 41°39′17″ (J2000.0). The estimated integral flux for this γ-ray source is about 8% of the Crab Nebula flux. The data are consistent with a pointlike source. Here we present a detailed description of the standard two-dimensional analysis technique used for the analysis of data taken with the Whipple Observatory 10 m telescope and the results for the TeV J2032+4130 campaign. We include a short discussion of the physical mechanisms that may be responsible for the observed γ-ray emission, based on possible association with known astrophysical objects, in particular, Cygnus OB2.
