Meeting of ALMA Young Astronomers 2023
March 10th marked the successful completion of the second Meeting of ALMA Young Astronomers, MAYA 2023. The goal of MAYA is to provide a platform where early career astronomers can present their recent ALMA work, and to facilitate new collaborations and projects through the interaction with other participants and staff working in the ARC nodes. […]
ALMA Data Reduction Training Day: Dec 9, 2022
Following the 6th Netherlands ALMA Science Day, on Thursday, December 8, 2022, we will host an ALMA Data Reduction Training Day in-person in HL 111. The training will begin at 9:30 AM and continue into the afternoon with coffee breaks and an hour lunch break. The Allegro team will be presenting a series of talks […]
6th Netherlands ALMA Science Day: Dec. 8, 2022
Allegro is organizing the 6th Netherlands ALMA Science Day on Thursday December 8, 2022, at Leiden Observatory.
ALMAxLeiden- “The Great Telescope Adventure” walking tour launched in Leiden
As part of the European City of Science Leiden 2022 project, Allegro has been developing a series of self-guided walking tours to introduce the public to ALMA and radio interferometry. The first tour entitled “The Great Telescope Adventure” has now launched. Participants take on the role of young researcher Robin, who is visiting ALMA only […]
Allegro releases CASSIS cookbook
Allegro has developed a simple cookbook that describes how to use CASSIS, a free interactive spectrum analyser. It is a powerful and user-friendly software to efficiently analyse spectral lines, for example to determine physical conditions like column densities and excitation temperatures of different molecules. The cookbook material can be downloaded from the Allegro website. It […]
Allegro launches Friends of Allegro 2023 program
Allegro is looking for applicants for its Friends of Allegro 2023 program, which aims to expand and facilitate connections across the ALMA community in the Netherlands. This program is open to Ph.D. students and Postdoctoral Researchers at Dutch research institutes and universities. Members of the Friends of Allegro program will be given opportunities to develop […]
Cycle 9 statistics
ALMA Cycle 9 received a total of 1769 proposals for a requested 27,912 hours for the 12-m array (4300 hours offered), 14,962 hours for the 7-m and 16,096 hours for the Total Power array. This number of proposals has been pretty stable in the past two years (after a record peak surpassing 1830 proposals only […]
Self-calibration and improving image fidelity for ALMA and other interferometers
The high quality of ALMA calibrated data sets allows researchers to tune the imaging parameters to their preferences, and to produce images ready for publication in few steps. Sometimes the exploratory analysis of calibrated datasets can also show the need for post-calibration processing. Identifying and/or diagnosing imaging problems from structured artifacts, or to identify errors […]
ALMA probes atoms and molecules, near and far
ALMA’s supreme capabilities to detect spectral lines across the Universe are beautifully illustrated in two recently published papers by astronomers in the Netherlands. Bouwens et al. (2022, ApJ 931, 160) give an overview of the design and results of the ALMA Large Program REBELS. Using an efficient selection scheme, REBELS detects no less than 18 […]
