ALMA Phase Correction Workshop

/in , /by

Allegro, Leiden, May 30 – June 3, 2016

A workshop focused on how to improve the ALMA phase corrections is jointly organized by the ALMA observatory and Allegro. It will be held at Leiden Observatory from May 30 – Jun 3. Participation is by invitation only. Find more details below:


 

DESCRIPTION

ALMA imaging observations – particularly on long baselines – are often limited more by phase fluctuations than atmospheric transmission or PWV. To enable more long-baseline or high-frequency observations, or improve existing data, we need to look at ways to improve the phase correction.

The aims of this workshop are:

  1. Review the methods that could improve ALMA phase correction and image fidelity. Including (but not limited to) baseline accuracy, WVR corrections, pressure and other environmental fluctuations, cycle times, online/offline WVR correction.
  2. Summarise the results from the related test observations during the 2014 and 2015 long-baseline campaigns, and identify and quantify the methods that do produce noticeable improvements.
  3. Make recommendations for changes in ALMA software, hardware and/or observing methods which will improve phase correction

ALMA Proposal Preparation Day 2016

/in , /by


Announcement from the Italian Node
11-12 April 2015 – Osservatorio di Radioastronomia Bologna, Italy

In preparation to the ALMA Cycle 4 proposal submission deadline of April 21st, the Italian node of the European ARC is organizing an “ALMA proposal preparation day” to support the ALMA users to prepare their proposals.

11-12th of April
This meeting will be held at the INAF-Osservatorio di Radioastronomia, Bologna, on the 11-12th of April.

During this meeting we will present short tutorials on the ALMA Observing Tool and on proposal preparation. Most of the time will be dedicated to the interaction of the participants with the ARC staff to get support in preparing their own proposals for ALMA Cycle 4.

Participants are invited to bring their own laptop to better participate in the interactive sessions and to directly work on proposal preparation. On request, few computers could be made available by the LOC.

Please notice that this activity is in addition to the usual “face-to-face” support that everybody can request at any time to the Italian ARC node via e-mail to help-desk@alma.inaf.it, or through the ALMA help-desk (register and access via the link “Helpdesk” on the ALMA Science Portal .

German ALMA Community Days 2016

/in , /by

Announcement from the German Node

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.

The next Call for Proposals for observing time with ALMA (Cycle 4) will be issued in March 2016. The deadline for proposals is expected to be on 21 April 2016, with observations starting in October 2016 (for more details, please see the pre-announcement in this newsletter). 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. The first day will feature an introduction to the basic radio astronomical concepts and terminology for non-radio astronomers. The second day will be devoted to practical information on ALMA-related tools and procedures including a hands-on tutorial on the ALMA proposal tool. Participants are encouraged to stay for a third day (8 April) to start preparing their own ALMA proposals with technical support from ARC node staff. While this event is open to all ALMA users and prospective ALMA users, preference will be given to astronomers from the local community (Germany,
Austria, Switzerland).

More information will be posted by late January on the homepage of the German ARC node at https://www.astro.uni-bonn.de/ARC/

Radio Interferometry: Methods and Science

/in , /by

Announcement from the German Node

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 course also comprises hands-on tutorials, where participants learn how to reduce interferometric data with the widely used astronomical software packages AIPS and CASA.

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, given by experts of the respective fields. The latest developments of selected world-leading radio/mm/submm interferometers will be presented as well.

Master students enrolled at the universities of Bonn and Cologne can take this course for credit. Other students and senior astronomers interested in the topic are very welcome to attend as well. We will offer remote access to the lectures and tutorials on a best efforts basis. Remote connections are in general possible to any European astronomical institutes, however, preference will be given to institutes from the local community (Germany, Austria, Switzerland). If you would like to follow the course from a remote location, please contact us before 1 April.

More information will be posted by late January on the homepage of the German ARC node at https://www.astro.uni-bonn.de/ARC/

ALMA Cycle workshop and NL Submillimeter Day 20-21 June 2012

/in , /by

Joint ALMA Cycle 1 workshop and NL Submillimeter Day
Tuesday, 24 April 2012 15:58

We are happy to announce a two-day workshop on ALMA Cycle 1 scientific capabilities held jointly with a NL Submillimeter Day. The meeting will take place on Wednesday June 20 and Thursday June 21 at Leiden Observatory.

On the first day we will introduce the scientific capabilities for ALMA Cycle 1, which will run from January 1 2013 until November 2013, with a proposal deadline in mid July 2012. In the afternoon we will discuss (other) submillimeter developments in the Netherlands, and discuss future prospects.

On the second day, we will demonstrate the ALMA proposal preparation software, with an emphasis on the new capabilities compared to Cycle 0. This will be followed by a hands-on training using this software. The use of software to simulate ALMA observations of scientific targets will also be demonstrated.
