German ALMA Regional Center (ARC) Node

The Atacama Large Millimeter/Submillimeter Array (ALMA) is a revolutionary interferometer for mm and submm astronomy in the Atacama desert in Northern Chile. It is operated by a global collaboration between Europe (ESO), North America (NRAO) and East Asia (NAOJ), in cooperation with Chile. The interface between ALMA and the user communities is provided by three ALMA Regional Centres (ARCs) in Europe, North America and East Asia.

The European ARC (EU ARC) is organized as a coordinated network with a central node at ESO Headquarters in Garching bei München and regional nodes located in Bologna(I), Bonn/Cologne(D), Grenoble(F), Leiden(NL), Manchester(GB), Ondrejov(CZ), and Onsala(S). The concept and the implementation of the EU ARC network has been described in a recent article in the ESO Messenger (Hatziminaoglou et al. 2015, Msngr. 162, 24).

The German ARC node is a collaboration of the universities of Bonn and Cologne. Its headquarters are located at the Argelander-Institut für Astronomie in Bonn. The German ARC node provides services to ALMA operations, the local astronomical community and the general public:

Cycle 4 Call for Proposals

The ALMA Director, on behalf of the Joint ALMA Observatory and the partner organisations in East Asia, Europe, and North America, has issued the ALMA Cycle 4 Call for Proposals.

The proposal submission deadline is 15:00 UT on Thursday, 21 April 2016.

Besides new capabilities and the option for large programs, Cycle 4 brings about significant changes in the so-called phase II process. In order to update the community on these changes and to optimally prepare proposers for the enhanced demands on PIs during the phase II process, we offer Community Days in Bonn on April 6-8 (see below).

German ALMA Community Days 2016

The next Call for Proposals for observing time with ALMA (Cycle 4) will be issued in March 2016 with a deadline of 21 April 2016. To prepare the local astronomical community for Cycle 4, the German ARC node organizes the German ALMA Community Days 2016 at the Argelander-Institut für Astronomie in Bonn on 6-8 April 2016. For details, please go to the Community Days homepage.

Registration is now open! Workshop places will be assigned on a "first come, first served basis". Please register here by 4 April 2016.

Training: Radio Interferometry - Methods and Science

The course "Radio Interferometry: Methods and Science", held in English at the university of Bonn in April-July 2016, offers a hands-on overview of major aspects of radio/mm/submm interferometry for master students, PhD students and senior astronomers. The lectures start with a general introduction to radio interferometry and data reduction, followed by an overview of various fields of research and the special observing modes that they require. The latest developments of selected world-leading radio/mm/submm interferometers will be presented as well. The course also comprises a hands-on tutorial, where participants learn how to reduce interferometric data with the widely used astronomical software package CASA.

We will offer remote access to the lectures and tutorials on a best efforts basis. If you would like to follow the course from a remote location, please contact us before 1 April.

Conference announcement: Half A Decade of ALMA: Cosmic Dawns Transformed

Tuesday, September 20, 2016 - Friday, September 23, 2016
Indian Wells, California, USA

The sensitivity and spectral grasp of the Atacama Large Millimeter/submillimeter Array (ALMA) have revolutionized the study of youngest structures in the Universe, from galaxy formation through the formation of stars and planets. ALMA has produced over 300 refereed papers at its four-year mark, reporting impressive and scientifically compelling results as the most sensitive and highest resolution mm/submm interferometer in the world.
This international four-day conference will highlight ALMA results at the threshold of the array's fifth year of science operations and bring together researchers from around the world to motivate collaborations for ALMA Cycle 5. Science topics will include all fields of astronomy, from cosmology and galaxies in the distant Universe, nearby galaxies and the Galactic Center, interstellar medium and star formation in our Galaxy, astrochemistry, circumstellar disks, exoplanets, solar system, stellar evolution, and the Sun. The conference will feature invited and contributed talks as well as poster sessions. Early career researchers and students are particularly encouraged to attend.
For more information, visit the conference website.

Job opportunity at the German ARC node

The German node of the European ALMA Regional Centre (ARC) invites applications for a postdoc position based at Bonn university. The position offers the opportunity for research in one of the major centres of radio astronomy in Germany as well as an in-depth involvement in the development and operations of ALMA.

The appointee is expected to support the technical and user support of ALMA, as well as conduct his/her self-defined research (50/50). Depending on his/her expertise, he/she shall work on single-dish integration efforts, including wavelet-based deconvolution tasks, or the development of polarization tools and calibration resources. more ...

ALMA joining 1mm Very Long Baseline Interferometry (VLBI)

NRAO is pleased to announce that the call for 1mm Very Long Baseline Interferometry (VLBI) proposals to use phased ALMA at Band 6 in Cycle 4, in collaboration with the Event Horizon Telescope Consortium (EHTC), will be released to coincide with the ALMA Cycle 4 Call for Proposals in March 2016. The EHTC is expected to comprise the Submillimeter Array, the James Clerk Maxwell Telescope, the Submillimeter Telescope, the Atacama Pathfinder Experiment, the South Pole Telescope, the Large Millimeter Telescope Alfonso Serrano, the IRAM 30m telescope, and an antenna from the Northern Extended Millimeter Array. Additional information will be made available in the ALMA Proposer's Guide at the ALMA Cycle 4 Call for Proposals in March 2016.

ALMA Cycle 4 Information for Large Programs

As indicated in the pre-announcement, the Joint ALMA Observatory (JAO) will accept proposals for Large Programs for the first time in Cycle 4. If you consider sumbitting a proposal for a Large Program, please read carefully these guidelines.

ALMA joining the Global mm-VLBI Array (GMVA)

The phased ALMA may participate in some GMVA observations during ALMA Cycle 4 (Oct 1 2016 - Sept 30 2017). The number of ALMA dishes in the phased array is likely to be 30-40. ALMA will not be in a configuration suitable for VLBI during GMVA Session II 2016, but Session I in 2017, which is likely to be in March or April, should provide an opportunity for GMVA + ALMA observing. If you consider sumbitting a proposal for GMVA observations including phased ALMA, please read carefully the instructions and restrictions.

New Science Verification data available

A new installment of Science Verification data is available, demonstrating the Band 4 capabilities: IRAS16293-2422 spectral line observations in Band 4 (CH3CN, CH3OH) with the 12-m Array. more ...

Start of European ARC Announcements

As a complement to local and European-wide newsletters, announcements relevant to the ALMA user community in Europe are now posted at the new European ARC Announcements. EU ARC Announcements are published right after they have been received and provide the community with up-to-date ALMA Science and ALMA Programme news, information related to data reduction and tools (e.g. CASA), and others.
