Ester Aliu, for the VERITAS Collaboration
The Cygnus region is a nearby very active star forming region, containing
several OB associations, considered as tracers of young pulsars. Above 12 TeV,
the Milagro Collaboration has reported the discovery of a very large source,
MGRO J2019+37, lying towards the Cyg OB1 association, at the edge of the Cygnus
region. The young and energetic pulsar PSR J2021+3651 has been proposed to
power this emission. We present here the result of deep VERITAS observations of
this region at energies above 650 GeV. These observations unveil extended and
complex TeV emission compatible with MGRO J2019+37, likely made of multiple
sources, and a clearly separated point source emission from the direction of
CTB 87, a pulsar wind nebula candidate. We will also report on the detection of
TeV emission from the young Galactic SNR CTA 1, likely powered by the first
pulsar discovered through its gamma-ray radiation.
