Groningen, yesterday. 🟥 #OrganizeTheRUG

We have first light on our Large Aperture Telescope! www.simonsfoundation.org/2025/03/17/s... After installing our mirrors over the last few weeks, we have started looking at the sky. We are still tuning the telescope, but we can already make maps of objects in the sky, like Mars. ☄️🔭🧪

Join us tomorrow, March 18th, for the strike of @unigroningen.bsky.social and Hanze University of Applied Sciences against the annually increasing budget cuts on higher education! Check the full program here: organizetherug.wordpress.com/strikes/ 🟥 #OrganizeTheRUG 🧪

Strikes! / Stakingen!

We gaan staken! / We’re going on strike! (English version below) Om ons te verzetten tegen de voorgenomen bezuinigingen op het hoger onderwijs hebben vakbonden AOb en FNV officieel een stakingstraj…

Budget cuts are not "just" a US issue. The Dutch government has planned budget cuts for over half a billion euros from higher education. This will lead to a disastrous deterioration of the quality of education and research. And that's why we are striking! 🟥 🧪

A small experiment for making #herakoi more accessible. And now you can take your blip-blop sonification machine everywhere! 🐡

Another round of AtLAST Forum is happening today @ 14UTC. If you don't know what to do during your lunch break and are curious about last month's Forum, go check the Forum playlist on the @atlastdesign.bsky.social YouTube channel: tinyurl.com/atlast-forum 📡 ☄️ 🔭 🧪

The next AtLAST forum is planned for this coming Thursday March 6th at 14 UTC. Talks: 1) telescope design, 2) the science shaping the design, followed by an open discussion. For details and zoom link check www.atlast.uio.no/news-and-eve...

Kudos to Gabriella Di Gennaro for this. Finding radio haloes in distant galaxy clusters is a tricky, but not impossible business. And indeed, these are galaxy clusters observed when the Universe was only around half of its age! #extragalactic 🧪🔭

Hunting for radio halos at high-z, by DiGennaro+ Diffuse emission is searched in a sample of 56 MaDCoWS galaxy clusters at 0.78 < z < 1.53. Possible halo-like diffuse emission is reported at 144 MHz in 5 of them arxiv.org/abs/2502.19273

The skies above Paranal are at risk from a proposed industrial megaproject.  This would be located in the vicinity of ESO's Observatory. If constructed, it would irreparably impact astronomical observations. Read more: https://www.eso.org/public/news/eso2501/ 🔭  📷 ESO/P. Horálek

World's darkest and clearest skies at risk from industrial megaproject

On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.

Do not miss the first AtLAST Forum tomorrow 6 Feb at 8 UTC. This is a platform for the community to exchange ideas and opinions about AtLAST and anything related to it. There will be two talks followed by a plenary discussion session, see: www.atlast.uio.no/news-and-eve... 🔭🧪

Maybe it's just time to start rethinking the way we publish papers? Journals like @ojastro.bsky.social and Open Research Europe are free and open access – and the latter uses an open (imo, very interesting) approach to peer review. 🔭🧪

Emily Hunt@emily.space · 2y ago

Astronomy & Astrophysics have almost halved their page cap from 20 pages to 12 pages - you have to pay 150€ per extra page. The reasoning is that they're getting too many submissions. But surely this just encourages authors to submit *more* short papers? 🔭 www.aanda.org/2025-press-r...

One day late, but yet another work by Joshiwa van Marrewijk 🚀 Characterizing the statistical properties of noise in interferometric images is a tricky game. And, indeed, many past high-z lines might actually be just false detections of spurious noise features arxiv.org/abs/2501.03150 📡🔭🧪

An amazing piece of work led by (my brother in science) Joshiwa van Marrewijk and Thomas Morris. Are you building a single-dish telescope (not not talking about you, @atlastdesign.bsky.social) and want to test for mapping and filtering strategies, atmospheric mitigation, etc? Just ask maria. 📡🔭🧪

The Open Journal of Astrophysics@ojastro.bsky.social · 2y ago

New Publication at the Open Journal of Astrophysics: "maria: A novel simulator for forecasting (sub-)mm observations" by J. van Marrewijk (ESO, Garching, Germany) and 10 others based in Germany, USA, Norway, France and Italy. astro.theoj.org/article/1275...

La risposta è fare un bonifico a Open Arms.

Tiny, but significant milestone for #herakoi! Earlier this year, the SAIt invited me and @micginolfi.bsky.social to present our "motion-sensing sonification experiment" at the VITEII workshop. And today, we got a short proceeding out on #arxiv: arxiv.org/abs/2412.09152 🌌🔭🐡🧪

Hi, @atlastdesign.bsky.social! How blue is the sky in the submm?

This is the official account of the #AtLAST study funded by @ec.europa.eu. AtLAST is a next-generation sub-millimeter 50m single dish #astronomical 🔭 facility, with #Science 🧪, #Technology, #Sustainability and #Community engagement at its core. More on atlast.uio.no

Four key #AtLAST 🔭 🧪 contributors got their PhDs in 2024. Congratulations to Isabel Montoya Arroyave, Isabelle Viole, Alice Schimek, and Joshiwa van Marrewijk for their achievements! www.atlast.uio.no/news-and-eve...

Join us today at the EAS2024 SS27 “Towards mapping the submillimeter universe with AtLAST”: exciting talks about submm observations of the MilkyWay, our Sun, interstellar magnetic fields, the Magellanic Clouds, the CGM, the SZ effect and distant galaxies! #EAS2024Padova 🧪 🔭

The AtLAST design paper is out today. This is the result of almost 4 years of work by @tonymroczkowski.bsky.social , the team of engineers at OHB DC, Richard Hills, Pato Gallardo and the rest of the AtLAST team helping along the way arxiv.org/abs/2402.18645 🔭 🧪

Being cool, the Spiderweb way 🕸️ Marika Lepore led a re-analysis of the central region of the Spiderweb protocluster at z=2.16, combining Chandra X-ray and ALMA SZ data. And we find evidence for a strongly cooling core. More on arXiv: arxiv.org/abs/2312.06392 🔭🧪

The #AtLAST project was in the spotlight in the concluding remarks of the #ALMA 10th anniversary conference. A telescope such as AtLAST 📡 would (among other things) provide new targets for ALMA follow ups for a long time, keeping ALMA relevant well beyond the 2030s 🔭🧪

Are you excited about the potential for ALMA in the 2030s? Are you worried about how we'll get there? Then this workshop is for you!

Sensitivities for everyone! 📡 [feel free to drop me a message if you encounter any problems with the calculator] 🧪🔭

We have released a sensitivity calculator for the future Atacama Large Submillimeter Telescope #AtLAST. For those who want to try out what they can achieve with a very big dish on the Chajnantor plateau, more info here: www.atlast.uio.no/news-and-eve... 🧪 🔭

Ehi, I got a new office! 🔭

and here I am, just a random astroguy in complete awe 🔭 www.esa.int/Science_Expl...

The AtLAST team met this week at ESO Garching for the annual consortium meeting to discuss the progress and next steps of the design study of the largest submillimeter single dish telescope and first net positive astronomical facility ever planned 🔭🧪
