The era of the HST is nearing its end and with it our main eye on the UV. While we eventually need a new big UV telescope, the UltraViolet EXplorer (UVEX) could be an important UV eye for the next decade. NASA now selected it for further study: nasa.gov/press-release/…

HUBBLE tweets about our new paper on M33 X-7 😍. See the full paper in A&A doi.org/10.1051/0004-6…

Hosting the most massive stars known to date, 30 Dor is a rosetta stone for massive star evolution. #JWST has now taken first images with NIRcam and MIRI of this region in the LMC. ESA Webb Telescope news: esawebb.org/news/weic2212/ STScI NASA Webb Telescope news: webbtelescope.org/contents/news-…

Setup almost complete for our Atomic Data Workshop at Uni Heidelberg supported by the Milchstrasse and the DFG public | @[email protected]. Reception starts in half an hour.

Day 2 of the Atomic Data Workshop Uni Heidelberg is kicked off by Stefan Shippers from Uni Gießen telling us about laboratory measurements of atomic data ⚛️ Milchstrasse DFG public | @[email protected]

Some impressions from our #astroatom astrophysical talks yesterday, where we discuss our needs of atomic data with the colleagues measuring and calculating them. The workshop is supported by Milchstrasse and DFG public | @[email protected].

Our last speaker before lunch is Pedro Amaro from NOVA Uni Lisbon talking about highly charged Fe ions #AstroAtom

How can we get more and better atomic data for #astrophysics? This is what we discuss at our #astroatom Atomic Data Workshop here at Uni Heidelberg/@zah_hd. Here is our first group picture of the in-person participants:

After an intensive, but very productive week, our Milchstrasse #astroatom Atomic Data Workshop @zah_hd/Uni Heidelberg has come to a close. With new insights gained about each other's field, we are looking forward to new collaborations and future projects.

Interested in joining our hot star atmosphere group @zah_hd Uni Heidelberg? With you as a postdoc in our group, we would like to work towards a multi-dimensional treatment of hot star winds. Sounds great? Than take a look at the full job ad: wwwstaff.ari.uni-heidelberg.de/ansander/?cont…

Most astrophysicists don't wear a suit very often, but on some occasions we do. I'm honoured to receive the Klaus-Georg and Sigrid Hengstberger Award for Young Scientists 2022 at the annual celebration of the Uni Heidelberg

Wrapping up the day is Andreas Sander providing a summary of various types of stellar winds for gravitational-wave sources. #GWPAW22 #StellarWinds

It's paper day! 🎉 Happy to share our new paper published in A&A journal letters about the first detection of intermediate-mass stripped stars at low metallicity, a missing link towards forming Be X-ray binaries and double neutron star mergers. aanda.org/articles/aa/fu…

#ENT2023 Wieder ein gelungenes Jahrestreffen unserer "Emmys" bei bestem Wetter ☀️🌳, guter Laune und viel gegenseitiger Inspiration, dokumentiert von Svea Pietschmann. Danke dafür und an das #DFG-Orga-Team #Karriereförderung! #EmmyNoether #ECR

Superluminous supernovae, black hole mergers, and many more astrophysical puzzles are connected to massive stars at subsolar metallicities, which we investigate in the X-Shooting ULLYSES collaboration. Paper I has officially been published today: aanda.org/articles/aa/fu…

For massive stars, the ultraviolett spectral region contains unique diagnostics and the HUBBLE 🛰️telescope is our unique eye on it. This year's proposal results are just out and my #Hubble proposal got accepted.🥳
