Query: G133.50+9.01: A likely cloud-cloud collision complex triggering the
  formation of filaments, cores and a stellar cluster   We present compelling observational evidence of G133.50+9.01 being a bona
fide cloud-cloud collision candidate with signatures of induced filament, core,
and cluster formation. The CO molecular line observations reveal that the
G133.50+9.01 complex is made of two colliding molecular clouds with systemic
velocities, -16.9 km s-1 and -14.1 km s-1. The intersection of the clouds is
characterised by broad bridging features characteristic of collision. The
morphology of the shocked layer at the interaction front resembles an arc like
structure with enhanced excitation temperature and H2 column density. A complex
network of filaments is detected in the SCUBA 850 {\mu}m image with 14 embedded
dense cores, all well correlated spatially with the shocked layer. A stellar
cluster revealed through an over-density of identified Class I and II young
stellar objects is found located along the arc in the intersection region
corroborating with a likely collision induced origin.
