Cycle 7 Call for Proposals

The ALMA Director, on behalf of the Joint ALMA Observatory (JAO) and the partner organisations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 7 Call for Proposals (CfP) for scientific observations to be scheduled from October 2019 to September 2020. It is anticipated that 4300 hours of the 12-m Array time and 3750 hours of the Atacama Compact Array (ACA) time, also known as the Morita Array, will be available for successful proposals from Principal Investigators (PIs) in Cycle 7.

The Cycle 7 proposal submission deadline is

For more information please visit the ALMA Science Portal.

Proposal Preparation Day – March 28th, 2019

Prior to the deadline for the ALMA Cycle 7 proposal submission (April 17th), Allegro will host a Proposal Preparation Day. Bring in your proposals and we will assist you with the technical aspects and help you in exploring their feasibility, while you work on it during that day. Allegro staff will be there to provide tips & tricks and answer all your questions.

Date: Thursday, March 28th, 2019 (9:30-17:00h)
Address: Niels Bohrweg 2, 2333 CA Leiden, the Netherlands — Huygens building — Room HL-111

You can register for the Proposal Preparation Day at the following link.

In addition to this proposal preparation day, remember you can always ask support from Allegro to help you with your proposals or ALMA related questions at any time.

    DIRECTIONS

    -Directions to Leiden Observatory

    Note that this is not the old Observatory in the center of Leiden.

    There are regular buses from the Leiden Centraal station, buses 43 (direction Den Haag) or bus 57 (direction Nieuw Vennep). These take around 7 minutes. Please see the link below for more specific details if you will be coming by bus.

    Instructions on how to get to Leiden Observatory, including transportation from Schiphol Airport, can be found here:
    http://www.lorentzcenter.nl/howto.php
    And a site map can be found here:

    lorentzcenter

    Note these specify the route to the Lorentz Center, which is in the forward leaning building in the photo. Leiden Observatory and Allegro offices are located on the 4th and 5th floor of that same building. The event will be held in the joining taller building – The Huygens building.

    -Directions inside the building:

    The event will be held on the 1st floor of the Huygens Building (HL), room HL 111.

     

The black hole at the heart of our Galaxy

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Galaxy comes from a smaller region than previously thought. This may indicate that a radio jet from Sgr A* is pointed almost toward us. Please find more information on the Press Release.

Announcement of 3mm VLBI in Cycle 7

It is expected that phased ALMA will participate in some GMVA observations during ALMA Cycle 7 (Oct 2019 – Sept 2020).
There are likely to be ~43 ALMA antennas available to the ALMA observation, but the phased sum used for VLBI may be constructed only from those that lie within a circle of radius 0.5 km. GMVA session dates for 2020 are not yet fixed but Session I in 2020, which is traditionally in the period March-May, would provide an opportunity for GMVA + ALMA observing.

ALMA Cycle 7 Pre-annoucement

The Joint ALMA Observatory (JAO) will start the next cycle of observations (Cycle 7) in October 2019. A Call for Proposals (CfP) with detailed information on Cycle 7 will be issued in March 2019, with a deadline for proposal submission in April 2019. This pre-announcement highlights aspects of the Cycle 7 proposal Call that are needed to plan proposals.

Issues affecting CASA mosaic imaging

The ALMA Observatory circulated a report of issues affecting mosaic images produced with CASA in ALMA Cycles 1-5.

Over the course of the last several months an issue in CASA mosaic imaging was recognized. The Observatory elected to understand and characterize the issue before informing the user community of potential impacts on the resulting images. The CASA team has now identified a couple of issues using both the 7-m and 12-m arrays over the course of the past few cycles and CASA releases. The full extent of the data affected is still being investigated.

You can read further details on the identified issues in this link to the Science Portal.

ALMA Cycle 6 Proposal Review: Detailed Report

A detailed report on the outcome of the ALMA Cycle 6 Proposal Review Process is now available. The report details the proposal review process, proposal statistics, and regional distributions, as well as the proposal distribution across science categories and receiver bands.

The report can be downloaded as a pdf document.

New ACA observatory filler programs for Cycle 5

The ALMA Observatory announces four filler programs that have been approved on the Atacama Compact Array (ACA), also known as the Morita Array. The programs were designed to fill a gap in the ACA observing schedule in the remainder of Cycle 5 between LST of 22 and 1.5 h. The programs were selected based on input from scientists at the Joint ALMA Observatory (JAO) and the ALMA Regional Centers (ARCs). The proposed programs were reviewed by the ALMA Integrated Science Team (IST) with final approval by the ALMA Director.

The approved programs are:

2017.A.00043.T: Time evolution of CO & H2O in the Martian atmosphere during a large-scale dust storm.
This project will monitor the evolution of CO and H2O in the Martian atmosphere during the recent dust storm.

2017.A.00053.S: ALMA ACA Band-8 observatory project: Mapping fine structure lines of neutral atomic carbon in local bright galaxies
This project will map the spatial distribution of the 492 GHz neutral carbon line in four nearby galaxies. The galaxies and map sizes are listed in the Table.
Galaxy Map size
NGC 7862 125″× 20″
NGC 55 90″× 30″
NGC 660 105″× 30″
ESO 353-G020 55″× 10″

2017.A.00054.S: ACA Observatory Project: SMC Band 6 CO and continuum mapping
This project will map a large area (~ 0.34ox 1o) toward the North bar in the Small Magellanic Cloud (SMC) in 12CO(2-1), H(30) alpha, and the continuum.

2017.A.00056.S:The nature of Planck compact sources at 353 microns
This project will conduct a survey of Planck sources at high galactic latitude in the Band 6 continuum to determine the nature of these sources. These observations could also potentially identify new calibrators for ALMA high frequency observations.

The data from the proposals will be quality assessed by the JAO and released through the ALMA Archive with no proprietary period. Any remaining PI science programs and activities to commission new capabilities on the array will have priority, and therefore the above programs may not be completed in full.

ALMA development roadmap for the next decade

The ALMA Board approved the ALMA Development Roadmap for the next decade. The current development priorities as based on scientific merit and technical feasibility, are:

  • to broaden the receiver IF bandwidth by at least a factor two, and
  • to upgrade the associated electronics and correlator.

These developments will advance a wide range of scientific studies by significantly reducing the time required for blind redshift surveys, spectral scans, and deep continuum surveys. In order of scientific priority, receiver upgrades are recommended for intermediate (200-425 GHz), low (< 200 GHz), and high (> 425 GHz) frequencies. The Board acknowledges that there are other potential development areas for the future for which the science cases and technical feasibility need to be further demonstrated.

A document summarizing the development priorities for the Observatory out to 2030 is presented here:
