I've been thinking for a long time whether I should publish this for you. Now it is hard for me to describe this post in words. I will just leave it here to share with you the pain of my country. The war that Russia started.
Dear all,
it is our great pleasure to release the 1st announcement of our StellarOrigins2025 conference! #stellarorigins2025

Absetzung der Astrologie-Show nun bestätigt, berichtet der Standard. Sehr erfreulich, dass im ORF diesbezüglich ein Umdenken stattgefunden hat 👏 derstandard.at/story/3000000… @univienna
Offener Brief zur @ORF-Sendung "Blick in die Sterne"
Die Professor*innen des Instituts für Astrophysik wenden sich in einem offenen Brief an ORF Programm-Direktorin Stefanie Groiss-Horowitz. @stefaniegroiss

EMERGE V is out. We created a toy model (incl. predictions) to explain why Hub-Filament Systems evolve differently than filaments in isolation: a change from filamentary to spherical geometry triggers global collapse.

Another day, another EMERGE paper. This time Andrea Socci shows that fibers are formed as part of the gas fragmentation process in all type of low- and high-mass SF regions. They are everywhere! #univienna

Today is EMERGE paper day! Using ALMA observations, Andrea Socci demonstrates how fibers adapt their width to their environment. The debate is over: filaments do NOT have a constant width! 😎arxiv.org/abs/2403.08091

Over the past years, a team of ~100 astronomers from around the world worked to hone the science cases for #AtLAST. The result is a compendium of eight white papers and an overview report. Read more about them and find all the relevant links here: atlast.uio.no/news-and-event…

This has been waiting for a long time, but is finally out. This is actually a “just” a pre image to find spectroscopic targets to measure the ice content of the cloud, but I knew it would be visually spectacular. The aligned protostars were a total surprise! #jwst @NASAJPL
The stars, they aligned 🎶
See how those bright red, clumpy streaks are all slanted in the same direction to the same degree? They show aligned protostellar outflows, or jets of gas from newborn stars. Webb captures this phenomenon for the first time: go.nasa.gov/4b9t6o9

ALT A portion of the young star-forming region Serpens Nebula. It’s filled with wispy orange and red layers of gas and dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. There are wispy blue filaments of glass in the bottom right corner of the image. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.

“Mi generación salvó al mundo”
Y tiene toda la razón.
Every #DDay I come back to Harry Billinge ❤️
If you’re tempted to moan about something meaningless or complain today… watch Harry and think about what he, and many others, went through for the freedoms we all too often take for granted.
There aren’t many of those heroes left but they have so much to teach us.
We’ll be playing music to commemorate the anniversary throughout the day on @ClassicFM

¡Feliz San Isidro!
Quejarse de Madrid y de los madrileños se ha vuelto un meme en redes sociales. Y muchas veces con razón.
Hoy quería compensar hablando por un día de lo que me gusta (hace falta más positividad aquí).
Un hilo personal de cariño a Madrid 👇
First paper of my PhD, Francesca Bonanomi! 📡📡📡 If you are doing ISM observations with #ALMA, you better chech this out. We hope it scares you! 😱 arxiv.org/abs/2405.09290
If you want to know about fibers and how low- and high-mass stats form in them check our first EMERGE paper: arxiv.org/abs/2403.08091
More coming soon! 😋

Das Forschungsinteresse der Astrophysikerin Sylvia Ploeckinger besteht darin, Simulationen zu erstellen, um Theorien zur Kosmologie zu testen.
Über eine Elise-Richter-Förderung des @FWF_at kann sie bedeutende Beiträge zur Erforschung des Universums leisten. 🔭@tu_wien @univienna
