Great! I just discovered that colleagues from NAOJ have partnered with Asahi Astro LIVE so that you can now watch on YouTube the ALMA camera feed looking at the ALMA Compact Array and surrounding antennas… on certain days you will be able to see our transporters, Otto and Lore!

And on windy weather, you can see the vibration on the camera…

Feliz de haber podido contribuir al día de la astronomía este viernes 20 de marzo en las jornadas de puertas abiertas de ESO y ALMA…

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!

Teams using our ALMA Observatory have been able to clearly show how magnetism has a pre-eminent role in young star accretion and growth!

The best part is that the lead scientist for that paper is our colleague Paulo Cortés, who apart from doing notable science is also responsible for the scientific acceptance of ALMA software releases!

We have updated our website to communicate the status and the future benefits of ALMA's Wideband Sensitivity Upgrade in our site for scientists:

When is heavy water (i.e., that formed with deuterium instead of simple hydrogen) formed in the universe? Very early into protoplanetary system formation, it seems!

«Our detection indisputably demonstrates that the water seen in this planet-forming disk must be older than the central star and formed at the earliest stages of star and planet formation,” shares Margot Leemker, lead author on this paper, and a postdoc with the Department of Physics, University of Milan, Italy. “This presents a major breakthrough in understanding the journey of water through planet formation, and how this water made its way to our Solar System, and possibly Earth, through similar processes.”»

A group led by Fujimoto-san et al have uncovered a primordial galaxy, just 930 million years after the Big Bang (z=6.072). The galaxy is composed of at least 15 dense, star-forming clumps embedded within a rotating disk like a "Cosmic Grape". These clumps, with sizes ranging from 10 to 60 parsecs, dominate 70% of the galaxy's UV light, and are reshaping our understanding of early galactic structure formation. More than 100 hours of joint ALMA and JWST observations were made, amplified by gravitational lensing, making this one of the most studies early galaxies.

This is my second migration on Mastodon, so I think an Introduction might be in order. I'm moving in to this account (that had lived independently, to test some of Mathstodon features) after astrodon.social is being sunset. Hope that Astrodon as a concept still lives!

I currently work in Systems Engineering for radio telescopes (in particular, the ALMA radio interferometer). I’ve also worked in software development and management for the SKAO observatory, and for the archive department at ESO. Of course, I'm also very interested in math (specially that having to do with system theory), so I'll try to get a bit stronger there.

Glad to see you all around!
