The Cyg OB2 Radio Survey (COBRaS) is designed to exploit e-MERLIN's enhanced capabilities to conduct uniquely probing, targeted deep-field mapping of the tremendously rich Cyg OB2 association in our Galaxy. The project aims to deliver the most detailed radio census for the most massive OB association in the northern hemisphere, offering direct comparison to not only massive clusters in general, but also young globular clusters and super star clusters.
Time Allocation: 294 hours (e-MERLIN including Lovell Telescope).
The Cyg OB2 Radio Survey (COBRaS) is designed to
exploit e-MERLIN's enhanced capabilities
to conduct uniquely probing, targeted deep-field
mapping of the tremendously rich Cyg OB2 association
in our Galaxy. The project aims to deliver the most
detailed radio census for the most massive OB
association in the northern hemisphere, offering
direct comparison to not only massive clusters in
general, but also young globular clusters and super
star clusters. With the COBRaS Legacy project we
will assemble a uniform dataset of lasting value
that is critical for advancing our understanding of
current astrophysical problems in the inter-related
core themes of:
1) Mass loss and evolution of massive stars
2) The formation, dynamics and content of massive OB
associations
3) The frequency of massive binaries and the
incidence of non-thermal radiation
Based on a total awarded allocation of 252 hrs and
42 hrs for C- and L-band observations, respectively,
the substantial COBRaS dataset will be powerfully
combined with other multi-waveband surveys of the
Cygnus X region, both current (IPHAS, Spitzer, and
Chandra) and in future programmes (Herschel and JWST).
This project will therefore not only yield
substantial results for the key science areas
identified above, but it will also provide new
perspectives for numerous additional archival
studies in stellar and extragalactic astrophysics.
The COBRaS project will thus yield a very valuable
Legacy dataset for the wider community.
