Science Highlight: Even Better Together

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 […]

Moving to the New Building

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 […]

Netherlands ALMA+JWST Joint Science Day

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 […]

ALMA Cycle 10 Statistics

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 […]

Lorentz Workshop: Tuning to the high frequency ALMA Universe

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 […]

New Allegro computing hardware

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. […]

Science Highlight: All quiet at z=4.5

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 […]
