Welcome to ALMA and the European ALMA Regional Centre!

ALMA (Atacama Large Millimeter/submillimeter Array) is the world's largest ground-based facility for observations in the millimeter/submillimeter regime located on the Chajnantor plateau, 5000 meters altitude in northern Chile. It enables transformational research into the physics of the cold Universe, probes the first stars and galaxies, and directly images the formation of planets. ALMA comprises a giant array of fifty 12-m antennas, which can be configured to achieve baselines up to 16 km. It is equipped with state-of-the-art receivers that cover all the atmospheric windows up to 1 THz. In addition, a compact array of 7-m and 12-m antennas greatly enhance ALMA's ability to image extended sources.

The European ALMA Regional Centre (ARC) provides the interface between the ALMA project and the European science community. It supports its users mainly in the areas of proposal preparation, observation preparation, data reduction, and data analysis.

Below you can read the latest Announcements from the European ARC Network.. More details and up-to-date information can be found in the News section and the ALMA Science Portal.

ALMA Cycle 7 Science Observations Status Update

Published: 16 Jul 2021

Cycle 7 PI science observations have been continuing, although with some significant interruption due to snowstorms at the end of May and in mid-June. Combined with pandemic conditions affecting maximum staffing levels at the site, this led to a delay in reaching the 12-m Array C43-7 configuration (completed on 12 July). Unfortunately, the delay has an impact on the configuration schedule for the remainder of Cycle 7.

Amplitude calibration issue affecting some ALMA data

Published: 15 Jul 2021

A visibility amplitude calibration error that affects fields containing strong line emission has been discovered in ALMA interferometer observations up to and including Cycle 7.

ALminer: ALMA archive mining and visualization toolkit

Published: 14 Jul 2021

ALminer (ALMA archive mining and visualization toolkit) is a novel Python-based code that enables users to efficiently query, analyse, and visualize the ALMA Science Archive. Users can programmatically query the archive for positions, target names, or any other keywords in the archive metadata (e.g. proposal title, abstract, scientific category) in a simple way. For more information about how to install and use ALminer, please visit the documentation or GitHub pages.

I-TRAIN: summer break and recordings from past events

Published: 13 Jul 2021

The training series I-TRAIN organised by the European ARC Network will be paused during the European summer months and then resumed in the autumn. In the meantime, videos and materials of the past sessions can be accessed from the ALMA Science Portal, including the last trainings on self-calibration and polarisation observations with ALMA.
