Face-to- face workshop for “SAMPLING-TOP- SCOPE”, December 14-16, Beijing -1 st announcement

The Planck satellite has discovered more than ten thousand Galactic cold clumps, the so-called “Planck Galactic Cold Clumps” (PGCCs). The PGCC catalog, covering the whole sky, hence probes wildly different environments, and represents a real goldmine for investigations of the early phases of star formation. After the successful start of the pioneer survey with the PMO 14-m telescope, we are conducting a joint survey (“SAMPLING-TOP- SCOPE”) towards 1000-2000 PGCCs with the SMT 10-m, TRAO 14-m, and JCMT 15-m telescopes. “SAMPLING” (SMT “All-sky” Mapping of PLanck Interstellar Nebulae in the Galaxy) is an ESO public survey inJ=2-1 12CO/13CO emission using the SMT 10-m telescope. “TOP” (TRAO Observations of Planck cold clumps) aims at an unbiased J=1-0 12CO/13CO survey of 2000 Planck Galactic Cold Clumps with the Taeduk Radio Astronomy Observatory 14-meter telescope. “SCOPE” (SCUBA-2 Continuum Observations of Pre-protostellar Evolution) is a legacy survey using SCUBA-2 at the James Clerk Maxwell Telescope (JCMT) of the East Asia Observatory (EAO) to survey 1000 Planck galactic cold clumps at 850 micron. We are also actively developing follow-up observations towards the SCUBA-2 cores detected in “SCOPE” with other ground-based telescopes (e.g. KVN 21-m, NRO 45-m, Effelsberg 100-m, Arecibo 300-m, SMA, and ALMA). Through these observations, we will study how dense cores form and how star formation varies as a function of environment, the universality of filaments in the cold ISM and their roles in generating dense cores, the existence of a density threshold for dense core formation, how dust properties change in different environments, and how dust properties affect the chemical evolution of dense cores.

To promote collaborations among team members on using the survey data for science, we will hold a face-to-face workshop on Dec. 14-16 at Peking University, Beijing, China. To indicate your interest in attending the workshop, please sign your name on the following doodle page:

JCMT Legacy Release 1 (SCUBA-2 850µm)

The JCMT is pleased to announce that its JCMT Legacy Release 1 (SCUBA-2 850µm) data set is now publicly available. This project makes available to the community uniformly reduced observations of most public SCUBA-2 850µm observations taken before 2013-08-01, as well as coadds and emission catalogs.  Please see our web page on the JCMT-LR1 for more details.

JCMT-LR1 (September 2015: SCUBA-2 850µm)

  • Public 850µm SCUBA-2 observations taken between 2011-02-01 and 2013-08-01.
  • Gridded onto HEALPix tiles using the HPX projection.
  • All reduced using the same SMURF makemap dimmconfig ‘jsa_generic’ (included in the Starlink 2015A release)
  • Coadds of all the reduced non-pointing observations which passed Quality Assurance coadded onto a single tile.
  • Catalogues of detected (>5σ) regions of contiguous emission (extents) towards each tile.
  • Catalogues of local peaks within the extents of each tile.
  • Over 2000 hours of observing time included.
  • Search CADC with proposal ID=’JCMT-LR1′ to view the coadds and catalogues.

 

Call for Proposals 16A

The East Asian Observatory is happy to invite PI observing proposals for semester 16A at JCMT (for details see here).

Semester 16A runs from 01 February 2016 to 31 July 2016. We are launching this Call through a new proposal handling system: Hedwig. You can reach Hedwig and find complete details of this Call at:

https://proposals.eaobservatory.org/

At your first visit, you should go to ‘Log in’ and generate an account. We hope you will find Hedwig easy to use: there is a ‘Help’ facility at the upper right corner, and individual Help tags at many places on the proposal pages.

The 16A Call for Proposals closes on the 22nd of September, 2015.

In addition, it should be noted that we will embark on survey observing in the 16A semester – and as such, PI time is more limited than the current semester, however we still strongly encourage PI submissions as at least 800 hours of time will be available to EAO and partner region investigators. Some alterations have also been made to the PI eligibility for Canada – please see the Call for details.

New Horizons for the JCMT with the East Asian Observatory: Latest Science from the JCMT

2015 IAU Splinter Session

August 6th 6pm-8pm  

Room 312 Hawaii Convention Center


The East Asian Observatory has forged a new path for the JCMT following the successful transfer of operation to EAO in March 2015. Operations immediately resumed with an EAO Pilot Science semester initiated in late March, taking successful science with JCMT’s signature instruments, and recommencing commissioning of the additional instrument elements (Pol-2 and FTS-2) for SCUBA-2. In this special session, we will present the latest results from the JCMT Legacy Surveys, completed in early 2015. We will also show some of the recent results from Pilot Science, and discuss the plans EAO and its partners have for continuing to keep the JCMT at the cutting edge of sub-millimeter science.
