3I/ATLAS: ALMA Detects Most Enriched Concentration Of Methanol And Hydrogen Cyanide Observed In Any Comet Ever

2/2 🧵
Fortunately, the Joint ALMA Observatory (and the ALMA Partnership) is not a monoculture, so not all computers run Windows, but macOS and Linux as well. Still learning if some Windows computers for some control systems might be at risk in our observatories, and maybe other observatories…

Resilient versus brittle systems:
7.4 Mw earthquake just in the vicinity of the ALMA Observatory: after a small initial scare, things keep working as normal (we might need to look at our hydrogen maser, though).
Single software update from a vendor that we don't contract: affects our email and messaging provider (Microsoft 365), degrades the operation of the entire observatory.

Today is my second year anniversary since I joined the Joint ALMA Observatory as JAO Development System Engineer! Can't believe how quickly time flies… and we've done an extraordinary amount of work in these 2 years!
The cyberattack sadly also affected our newsletter archive, so I cannot point to the nice entry that they published just one month after I joined.

Protecting ALMA’s skies Whitepaper: a study of the risks posed by radio frequency interference (RFI) to ALMA today and in the near future, from both ground-based and space-based sources of radio emissions. The paper identifies the vulnerable points eof the observatory, and discusses and evaluates potential mitigation measures.

ALMA, as part of the Event Horizon Telescope, is unveiling a new image of our Milky Way's supermassive black hole, Sagittarius A*, in which strong magnetic fields can be seen…
The most exciting part is that this hints to a jet that would be hidden from our vantage point in our galaxy… but imagine that! We might be like M87, just at a smaller scale!

Some time has elapsed since I first (and last) used the ALMA Helpdesk… #ALMA #AlmaHelpdesk #AlmaObservatory

Our colleagues even recorded a video of the process, and the reasons for this, including VLBI!

Brains have the alpha waves, computers have their clocks... and radio telescopes have hydrogen masers (essentially, radio-wavelength lasers) to keep both accurate timing and frequency, which are essential for radio inteferometers such as ALMA to work.
This masers live at 5000 m high at the Chajnator plateau, so the work itself is challenging!

Happy new year, and happy new ALMA 2024 Calendar!
For January, we have a very nice image: what the Chajantor plateau looked like last year when it was full of snow! And this is just the first month image in our ALMA 2023 Calendar, which you can download from our web in two languages:

This goes well beyond what was expected from ALMA: for the first time, astronomers have been able to observe a disc around a young star in the Large Magellanic Cloud, a neighboring galaxy. It’s the first time such a disc has ever been found outside our galaxy, and is identical to those forming planets in our Milky Way.

El Episodio 3 se llama ¿Quiénes usan ALMA para investigar?, y en él John Carpenter (Observatory Scientist) explica cómo ALMA recibe propuestas de observación de investigadores de todo el mundo, y los mecanismos existentes para seleccionar aquellas propuestas que van a escudriñar el cosmos en cada uno de nuestros ciclos de observación.

¡Hay más episodios disponibles en el podcast El Pequeño Universo de ALMA!
El Episodio 2 se titula ¿Qué hace que este observatorio sea tan especial?, y en él Giorgio Siringo nos explica cómo ALMA ha hecho posible ver una porción del espectro electromagnético que hasta recientemente estaba oculto, y por qué científicos de todo el mundo quieren venir a investigar en el Desierto de Atacama.

Episode 3 is called Who Uses ALMA for Research? and in it our Observatory Scientist John Carpenter explains how every year ALMA receives proposals from researchers from all over the world. Those proposals request much more time than it is available in a year, so we have mechanisms to select the ones that are going to gaze at the Cosmos for each cycle.

More episodes available for ALMA’s little universe podcast!
Episode 2 is What's So Special About This Telescope? and in it Giorgio Siringo explains how ALMA has made it possible to see a portion of the electromagnetic spectrum that was hidden to us until recently and why scientists from all over the world want to come to the Atacama Desert to do their research.

This is an excellent example of the ALMA capabilities, and what the ALMA partnership can achieve when we work together. This is the highest spatial resolution datacube ever produced by ALMA, at 5 milli arcseconds, using Band 10 at around 950 GHz, and the most extended configuration of around 16 km baselines.
A lot of technical ground was broken in order to achieve this result, so in the future it will be easier!

Thanks to the Event Horizon Telescope (EHT), of which ALMA is a major contributor, the EHT collaboration has been able to describe for the first time how light from the edge of M87's supermassive black hole spirals as it scapes the extraordinary gravitational field by looking at the polarization of its radio emission.

As I announced on Wednesday, the first short episode of ALMA Little Universe is out now! Point your podcast application to https://feeds.transistor.fm/alma-little-universe, or browse episodes at https://alma-little-universe.transistor.fm
This first episode is called What is ALMA?, and tries to answer that question in just 3 minutes and a half.
Please, give it a chance!

ALMA has a brand new podcast! Called ALMA Little Universe, it will debut its first episode on November 10th.
You can subscribe to its feed here: https://feeds.transistor.fm/alma-little-universe
And if you prefer a more application centric approach, use this link instead: https://alma-little-universe.transistor.fm/
There is a small (40s) trailer for you to test your podcast access now ahead of the first episode.

ALMA captured, for the first time, the accretion flow _towards_ a supermassive black hole. Identifying this flow had long been a challenge, due to the small scale of these regions and the complex gas motion near galactic centers. They saw where the foreground molecular gas absorbed the bright light coming from the Active Galaxy Nucleus, and evidence of its movement.

Another great ALMA image: a group of researchers led by ProfessorXX studied the triple system IRAS 04239+2436 on the radio signals of sulfur monoxide (SO) and studied the arms generated in that kind of interaction, and compared them with simulations, and the agreement was fantastic.
