It got worse. When I told ChatGPT that it was mistaken, it told me that it got confused by the journal name, which should be ApJ, not AJ. And then it produced the 'correct' paper (see below) WHICH DOES NOT EXIST AT ALL!!

Tomorrow I will be at a 'talk show' on the great outdoors organized by TU Delft, talking about stories from observing nights at high altitude.

Winner of two prizes at the Leiden Allegro ARC node competition, both the one for most requested hours (of all proposals combined) and for the smallest proposal 😁 #almacycle12

The usual curve of proposal submissions on ALMA deadline day. It looks like we may end up a bit lower than last Cycle, unless we get a final sprint. I'm going to bet on 1560. What's your guess?

Looks like we are somewhat below the trend of last year. How many people are still submitting in the final 10 hours? #almacycle12

Are we tired yet of PDS70? It's obviously the topic of many talks at the GAP (Giant Accreting Planets) conference. Nice cartoon by Luna Rampinelli!

This morning I Googled 'scattered light disk surface' to find an example image. One of the results was a SPHERE image gallery (left), but it immediately changed into a cute kitten (right) due to the 'Make America Kittens Again' filter that changes pictures of Trump to kittens. SPHERE is too orange 😂

Even more fascinating is the comparison with last year. JWST and Euclid are still popular as ever, but Gaia and INT dropped completely off the radar, as well as several others...

Fun homework exercise for my students: write an essay about your favorite telescope and why it's your favorite. Some clear popular winners, but also some surprises!

Next week I'm getting out of my comfort zone: talking about galaxies at Astronomy on Tap in Leiden!

Happy with the active discussions today at my first lecture! Let's see if it leads to more active engagement this semester. 💪

Ayumu Kuwahara shows yet another way to explain dust gaps in disks: apparently even low-mass Earth-like planets can create them due to the induced gas flow 🤯

Don't we all love a Zoom-Droste-effect-selfie? 😆

Even though the signal appears so simple (rapid radio flux variability), there are still so many possible options to explain fast radio bursts. The universe is a crazy astrophysical mystery. There's now an Astroflash group in Netherlands/Canada tackling this issue #NOVA25

So much physics involved if you want to simulate compact objects (supernovae, neutron stars, etc.) to compare with observational data. 🤯 All four fundamental forces are relevant! #NOVA25

Carbon chain molecules including PAHs have super cool shapes! JWST was clearly meant to study PAHs considering its mirror shape 🤣 @donnainfiorino.bsky.social #NOVA25
