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.

The web based analyzer for the spectrometer is coming together, although I still have to figure out a few things. This screencapture shows a few of the features, but nothing serious, just sliding the sliders and buttoning the buttons, then cycling through a few colors on the lamp in front of the phone.

It's still WIP but you can try it here: https://gheja.github.io/spectro-web/src/

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...

Spent a few hours at the Seattle Pinball Museum today. A great time as always. I made another field recording, and noticed again this constant pair of lines on the spectrogram at around 15.5k and just under 16k. I wonder what causes it? https://soundcloud.com/matthew-m-conroy/seattle-pinball-museum-iii #fieldRecording #pinball #sound #spectrogram #spectrograph

[#Life in the Universe ... and much more] A new-generation #spectrograph called #ANDES will soon be installed on the #ESO's #ELT (Extremely Large Telescope).

Objectives: to analyze the atmosphere of Earth-like #exoplanets in search of signs of life, to analyze the chemical composition of distant objects in the young #Universe, to measure the acceleration of the #expansion of the Universe, and more.

A revolutionary instrument, to be discovered here: https://www.irap.omp.eu/en/2024/06/eso-signs-a-construction-agreement-for-the-andes-instrument-on-the-elt/

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! 🤩

#ExSSV

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! 🇨🇱❤️

This his how a high resolution #spectrograph, designed for #exoplanets studies, looks from the outside. A big chamber, with isolation layers, tubes and warning signs #AstronomerLife #astronomy #NIRPS
