Description
We observed the first known very high energy (VHE) γ-ray-emitting
unidentified source, TeV J2032+4130, for 94 hr with the MAGIC telescope.
The source was detected with a significance of 5.6 σ. The flux,
position, and angular extension are compatible with the previous ones
measured by the HEGRA telescope system 5 years ago. The integral flux
amounts to (4.5 +/- 0.3stat +/- 0.35sys) ×
10-13 photons cm-2 s-1 above 1 TeV. The
source energy spectrum, obtained with the lowest energy threshold to
date, is compatible with a single power law with a hard photon index of
Γ = -2.0 +/- 0.3stat +/- 0.2sys.
