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 recounts of Cosmic Conundrums

Published: 15 Oct 2021

The European ARC network is launching the new virtual talk series "ALMA recounts of Cosmic Conundrums". In every talk of this series a major astronomical question is discussed. The invited speaker will describe the context of the question and then focuses on the ALMA contribution to the field, past and future. The aim of the series is to highlight the unparalleled contribution of ALMA to the broader astronomical landscape and to provide an outlook towards the future. 

The first talk of this series will take place December 1 at 14:00 CET. The talks will be broadcast through the Youtube channel of the European ALMA Regional Centre network.  More information on the first talk will be included in the November newsletter.

I-TRAIN #9: Stacking spectra in the image domain with LineStacker

Published: 07 Oct 2021

The European ARC Network invites users to an online training on using the software tool LineStacker. The session will be held on Friday October 15th, 2021, 11:00 CEST [Zoom link]. Line-Stacker (Jolly et al. 2020) is a new tool for stacking of spectral lines that can stack both 3D cubes or already extracted spectra.
