The new ALMA Band 1 receiver is an ALMA development project lead by East Asia as a collaboration of ASIAA, NAOJ, NRAO, and the Universidad de Chile that will provide access to the 35-51 GHz frequency window at high angular resolution and sensitivity from the southern hemisphere. Several key science cases have been proposed to be studied with the Band 1 Science Case aimed at greatly increasing the volume of the observable Universe and the range of observable frequencies and energies with ALMA. The two main scientific goals of the ALMA Band 1 project are the study of the evolution of grains in protoplanetary disks, from mm to cm sizes, and the detection of molecular line emission from high-redshift galaxies, tracing molecular emission from redshifts z~1-10. Additionally, there is a broad range of science goals covered by ALMA Band 1: high-resolution and high-sensitivity observations of Sunyaev-Zel'dovich effect (SZE) in galaxy clusters; observations of very small grains and spinning dust; study of the fine structure of chemical differentiation in cloud cores, tracing the very cold phase of the ISM and probing the smallest length scales of chemical variation; complex carbon-chain molecules, including the aminoacids and sugars from which life on Earth may have originally evolved; the opportunity to measure the initial mass-to-flux ratio of molecular cores through the detection of the Zeeman effect in spectral lines (CCS), ...
The ALMA Band 1 Development Project was approved by the ALMA Board in April 2016. At this moment, the first three prototype receivers are being finished and the production phase of the ALMA Band 1 receivers will start in early 2017. The delivery of the last Band 1 receiver to ALMA is planned for December 2019. The ALMA Band 1 Science workshop will provide the first opportunity to show the exciting new science ALMA Band 1 can deliver and to start preparing for the first observing proposals in the ALMA lowest frequency band.
The ALMA Band 1 Science Workshop will take place at the ASIAA (Academia Sinica, Institute for Astronomy and Astrophysics) in Taipei (Taiwan) from January 16 to 18 2017. It will consist of a few invited talks on the main scientific goals of ALMA Band 1, plus contributed talks. We also plan to have poster sessions.
The two days after the workshop, 19-20 January, will be dedicated to the discussion and planning of the upcoming Band 1 Science Verification phase. These closed sessions are in principle addressed to the members of the current SV team, but if you are interested in joining and/or in contributing to the Science Verification of Band 1, please write to the Project Scientist of Band 1, Oscar Morata (omorataasiaa.sinica.edu.tw).
