Overview
Overview of the CYGNUS X complex (Beuther et al. 2022):
grey 70mum, contours 250mum, red triangles mm clumps from Motte
et al. (2007). The blue squares outline the individual 4'x4'
NOEMA mosaics.
CASCADE is part of the Max Planck IRAM Observatory Program (MIOP)
that addresses several scientific topics from protostallar disks to
star formation and cosmology (MIOP).
CASCADE images large parts of the Cygnus X star-forming region at
high spatial resolution in the 3.6mm line and continuum emission
with NOEMA and the 30m telescope. The main scientific questions to
be investigated are:
- How does the gas flow from large cloud to small core scales?
- Do we find kinematic signatures of cloud collapse?
- How do the star-forming cores affect their environment? What are
the dominating processes of feedback from the forming and
newly-formed stars?
- What are the chemical gas properties and how do the change with
evolutionary stage?
Project Status
First moment map in HCO+(1-0) for the DR20 region (Beuther et al. 2022).
Over the entire Cygnus X molecular cloud, we are focusing on 40
mosaics of 4'x4' (78 fields each). For several sub-regions, a few
mosaics are concatenated to one larger mosaic (e.g., for DR20 above,
3 mosaics are stitched together).
As of summer 2022, more than 50% of the NOEMA data are taken.
Furthermore, all complementary 30m single-dish observations have
been conducted. Data reduction and analysis is ongoing.
Team
The CASCADE MIOP is a collaboration initiated by the Max Planck
Society and IRAM, but it is extended to a much broader international
community. The current team members are:
K. Menten, F. Wyrowski, H. Beuther, J.M. Winters, L. Bouscasse, S
Suri, W.-J. Kim, C. Gieser, M. Sawczuck, I.B. Christensen, I.M.
Skretas, F. Motte, N. Schneider, T. Csengeri, S. Bontemps, N.
Cunningham, G. Ortiz, A. Hernandez, D. Semenov, T. Hoang, K.T. Wong
Data & Publications
Data reduction and analysis are ongoing. While the first studies
will focus either on individual regions with the combined NOEMA+30m
data, or on larger sample approaches with the 30m-only data, in
follow-up steps, the data-sets of the whole region will be employed
to derive a more unified picture of the physics, chemistry and
kinematics in the framework of high-mass star formation.
