The first one is the Hubble Ultra Deep Field. The original Hubble Deep Field has the characteristic WFPC2 shape and two relatively bright white elliptical galaxies in the center and north center. 😁

Continuum-subtracted MgII pseudo-narrowband image example (gray color scale) and HST F814W images (blue color scale, probing the stellar light) of the final sample of galaxies that exhibit a P-Cygni profile in MgII, as well as a significant detection of extended MgII emission.
All thanks to the 3D outflow model that Ismael developed, which lets us identify the outflow properties based on the absorption / emission properties of MgII doublet in 3D. An example:
Using SED fitting we find:
(a) Galaxies with MgII outflows tend to have higher (specific) star formation rates and younger stellar populations—consistent with SF-driven winds.
(b) We also identify a trend between M* and central optical depth and an anti-correlation with opening angle.
I totally forgot to post about this new paper that my colleague Ismael Pessa recently got accepted. Remember when we were totally happy when we detected MgII in emission around galaxies in one object or via stacking? Well, now we make statistics on 47 individual galaxies!

Wie weit erstreckt sich die Andromeda-Galaxie über den Nachthimmel, wenn man ihren ausgedehnten Halo aus Gas sehen könnte? Diese Frage und mehr beantwortet Dr. Ramona Augustin in ihrem Vortrag innerhalb der Reihe Virtuelle #BabelsbergerSternennächte ✨ Jetzt online:

This is devastating for Carl’s family, and for his IPAC friends and colleagues. We are all shocked and saddened. His contributions to exoplanets and infrared science and the astronomy community will not be forgotten. 💔
The more obscure ones, not so sure about this, because I saw a lot late 90s in the theater, but most remain obscure.
Memento (2000)
Lola rennt (1998)
Jackie Brown (1997)
The Craft (1996)
The Basketball Diaries (1995)
E.T. (1983) - forever thankful at my mom that she took me at 4.5 years old
Jurassic Park (1993) - that scene where they are with their mouth open, that was the theater.
Titanic (1997) - happy to be part of the crowd.
The Matrix (1999) - went in without knowing what it was about.
Um, so the 2026 Oscars DO have a sense of humor.

George Efstathiou giving the AIP colloquium.
I am back in the same room as yesterday. This time listening to cosmology eminence George Efstathiou at the @aippotsdam.bsky.social colloquium speculating whether Dark Energy evolves (probably not).
David Hogg has written a white paper on doing astrophysics in the age of LLMs. It looks to be thought-provoking. My initial reaction is that either LLMs will destroy the field or they will force a reckoning with and re-imagining of the current system that often prioritizes output over quality. 🧪
As a scientist, I am quite offended by this nonsense.
Lecture hall of the AIP before tge ceremony
Attending the Wempe prize ceremony. This year it's going to Dr. Sebastian Kamann, who did his PhD with us and has been largely involved in the MUSE collaboration. His work has been instrumental in crowded field integral field spectroscopy. 🤩🌟💫
In the centre an opaque cloud of grey gas hides a star. Two strong beams of light from the star emerge from large holes in both sides of the cloud. The central cloud is surrounded by concentric, wispy shells of gas, illuminated by the star’s light. The shells reflect extra light where they’re hit by the twin beams. A crowd of smaller stars with cross-shaped spikes over them surround the nebula on a black background. Credit:ESA/Hubble & NASA, B. Balick (University of Washington
Hubble has captured a new view of the Egg Nebula 🥚 the first, youngest, and closest pre-planetary nebula ever discovered!

It’s not heroic to work when sick or race or play when injured. It’s damaging and dangerous and those that encourage or force it are doing their people an awful disservice (and ultimately harming their own and everyone’s interests too).
This image produced shows a MUSE NFM image of the AGN in NGC 985 with exquisite spatial detail. The green infalling cloud is ionized by the AGN, while the faint red dots are star forming regions. Proud of my student Lucas Ramos Vieira that found it

hehe, I skipped "panel" when reading:
"getting the solar system fixed turns out to be significantly more complicated than I had anticipated" :)
Now do Lise Meitner! How many times was she nominated? The answer will surprise you...
I just heard somebody say in a talk: "this is from a fairly old paper" - it was 2018!
oh, that looks like a great target!
No, as always, we astronomers have weird conventions in that FeII* is different from FeII in that it denotes fluorescent or stellar-like emission. Only in astronomy!
It's not recent. It denotes radio sources that are compact. Cas A* (the brightest of the bunch) is a Supernova remnant, Cyg A* and Cen A* are SMBH, but with compact, bright radio sources. As is, the obviously more famous Sag A*.
Oh, no! Not Catherine O'Hara... 😭.
