Another fun slide at the #ag2025goerlitz awards ceremonies by Frank Grupp of LMU who is honored - https://www.physik.lmu.de/de/aktuelles/newsuebersicht/news/frank-grupp-erhaelt-preis-fuer-instrumentenentwicklung-2025.html - by the @GermanAstroSoc for a major contribution to the #Euclid space observatory. Here he shows a star #spectrograph he built as a school project in the 1980s.
I started to work on a mini pocket spectrograph, the 3D model will be available for download, I just need to tune a few things.
I am also working on a little web based stuff to make sense of the things seen, strictly locally in the browser, on the client side.
It's a fun random side project, though I already bought about 8 different light bulbs just to see their spectrum...
Let‘s get this party started. After a wonderful welcome by @astrokiwi , we continue with Debra Fischer.
This is maybe a bit of a reminder that our field is very young and has come a far way in a short period of time!
A shout-out to the #HAPRS #spectrograph setting a new standard back in the days 
And well, then #Kepler happened, so the Doppler community had to give the stage to #transits! 
Hi folks! We're a novel type of EUV integral field #spectrograph launching on a #SoundingRocket from Poker Flat Research Range in March 2024!
We're part of a flare observation campaign with the Foxi 4 rocket
and the Hi-C sounding rocket.
We do #SolarPhysics and #Heliophysics #Research, as well as #AerospaceEngineering
Better sharing this late than never 
I'm happy to announce that I've been awarded a one-year #ESO studentship to work with Elyar Sedaghati and @JuliaVSeidel on #ESPRESSO 
See you in August, #Chile! 
#ELODIE is a #spectrograph that was able to measure the radial velocity of #stars via the #Doppler effect with a precision down to about 10m/s.
It is actually the successor of the #CORAVEL spectrograph with which Michel Mayor & Antoine Duquennoy studied the population of binary stars in the #solar neighborhood. #CORAVEL had a precision down to about 300m/s which is not enough to discover (most) exoplanets.
#ELODIE is thus a super coravel.
