Using observations of both JWST and ALMA, van Gelder et al. 2024 (2024, A&A 682, A78) unlock the secrets behind the emission of SO2 from the young protostars NGC 1333 IRAS 2A. This sulfurous compound signals evaporating ices but can also be released in accretion shocks where material enters the planet-forming disk. By combining the […]
Allegro, along with the rest of the Leiden Observatory offices, will be moving to the new Gorlaeus building at the end of March. The move will cause the Allegro staff and desktop computing resources to be offline for a few days. We will also use this time to transition our computing nodes to a new […]
On Monday, November 27, 2023, 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 that cover the following topics: how to […]
Allegro is pleased to announce the first ALMA+JWST Joint Science Day, which will take place on January 30th, 2024, at Kapteyn Astronomical Institute (Room 161 on the 1st floor) in Groningen. We would like to invite all members of our communities to present your latest scientific results obtained with ALMA and/or JWST. A particular emphasis […]
The ALMA cycle 10 proposal submission statistics again saw some new records. The number of overall submitted proposals for all arrays was 1679 – with 91 as ACA stand-alone projects and 44 large programs (compared to 40 large programs in Cycle 9). Even though the total number of submitted proposals is lower than for the […]
The ALMA partnership is organizing a conference to commemorate 10 years of ALMA Science Observations, taking place in Puerto Varas, Chile, on 4-8 December 2023. The aim of the conference is to look back on the observatory’s accomplishments, highlight the latest ALMA results from all scientific fields, as well as look forward to future technical […]
In the week of September 4-8, an ALMA-dedicated workshop will take place at the Lorentz Center in Leiden. The workshop aims at gathering the ALMA community to discuss and further develop the unique science that can be achieved at the highest frequencies offered (Bands 8, 9, and 10). ALMA is the only ground-based interferometer that […]
A joint Iran and Türkıye radio astronomy workshop is set to take place at Erciyes University in Kayseri in Türkıye in the next two weeks (Sep. 4-15). The workshop is part of the IAU Hands-On Workshops (I-HOW) initiative that aims to train young scientists in developing countries in accessing, analyzing and using the vast amounts […]
Allegro has purchased a new set of more powerful computing servers and a new disk server with a larger amount of storage space, in order to provide enhanced computing services for our user community. We will have five new computing servers available to our user community for the processing and analysis of their ALMA data. […]
Standard galaxy formation models expect that young galaxies should be highly turbulent and kinematically chaotic, as a result of violent gas accretion and frequent mergers. Observations appear to tell a very different story. In this paper, Roman-Oliveira (Kapteyn Institute), Fraternali and Rizzo (2023, MNRAS 521, 1045) show archival ALMA data of the [C II] 158 […]
