This is a very cool result, and an extremely interesting application of current ALMA Observatory capabilities, in particular its long baselines to get higher spatial resolution (i.e., how small are our pixels in the X and Y dimension). But to achieve it, the team had to make very detailed adjustments to the correlation and observation setups so that all those molecules could be observed during several observation runs, within the constraints of our current system.

With the Wideband Sensitivity Upgrade (WSU), many of those molecules will be able to be observed in many less observing setups, thanks to our wider bandwidth, but also with more detail in the spectral dimension (for each individual "pixel") thanks to our new correlators. So the number of spectral setups will be reduced, and the total observing time will be also reduced, allowing for more interesting science to happen!

That's the promise of the WSU, and we're working hard to fulfill it!

We have passed the Wideband Sensitivity Upgrade System Preliminary Design Review (PDR), and the Critical Design and Manufacturing Review (CDMR) for the Observing Support Facility (OSF) Correlator Room (OCRO)… learn more here! https://alma.loadingediciones.cl/dev/es/alma-moves-forward-with-its-scientific-upgrade-progress-on-the-wsu-project/

Youtube video from @esoastronomy on the Wideeband Sensitivity Upgrade… It is 6 months old, but from the point of view of what we will be attempting is quite apropos.

This yearly shutdown for ALMA is special: during this shutdown, the first equipment required for the Wideband Sensitivity Upgrade will be connected: the electrical interfaces for the OSF Correlator Room, which will be the home for the new Advanced Technology ALMA Correlator (ATAC), the new Total Power GPU Spectrometer (TPGS), parts of the Data Transmission Subsystem, and even from the computing side of things!

Ayer tuve el gusto de dar la charla inaugural en el evento Applied ReseaRch dAY (ARRAY) 2024 del Departamento de Informática de la Universidad de Santiago de Chile (USACH).

Las transparencias en español las podéis ver en SpeakerDeck, que sigue siendo el servicio de subida de charlas que menos se entromete en tu contenido. Pero aquí las he subido para que estén disponibles en caso de que les pase algo a esos servicios…

Además, la charla se retransmitió en YouTube, y podéis ver el inicio de mi charla en torno al minuto 12:50, o podéis empezar en el minuto 9:05 para ver la presentación que me hace Miguel Cárcamo.

En cualquier caso, y para estar más embebido aún en el Fediverso, he extraído mi charla y la he subido a la instancia de PeerTube de Trom.tf:

Slides in English of my talk on the Wideband Sensitivity Upgrade this morning at ARRAY 2024.

The title is the only part in Spanish in the slides… in English it would be “Computational Requirements of Large Scale Radio Astronomy: the ALMA Wideband Sensitivity Upgrade.”
