Just a huge thanks to our 1st semester students in #physics at the Universität Hamburg for their great motivation which makes it so enjoyable and a privilege to teach you introductory experimental physics!

It was a very nice defense with great and original results. Thanks Anton and all the best!

Searching for photon-ALPs mixing effects in AGN gamma-ray energy spectra. (arXiv:2208.00079v1 [astro-ph.HE]) relevance:89% arxiv.org/abs/2208.00079 #darkmatter Dieter Horns

This GRB is amazing and inspiring for anybody interested in gamma ray propagation. If the LHAASO famous 18 TeV photon is not background, there is an interesting story to tell. Have a look at our paper!

Dear doctoral researchers UHH - MIN-Fakultät! Our goal is to support you and to continuously improve the doctoral education at the MIN Faculty. To achieve this, we need your help! 💙 Please complete this short, anonymous survey on doctoral supervision and wellbeing: survey.lamapoll.de/Promovierende2…

Great summary NZZ about anomalous gamma-ray transparency for GRB221009A tinyurl.com/5ft4uzvc. But: the expected number of photons at 18 TeV varies between 0.00000001 and 5 (arxiv.org/abs/2210.07172) depending on how much dust there is in the universe!

Congratulations 🎊 that's a really nice new building!

Thanks for the support of UHH - MIN-Fakultät Universität Hamburg Quantum Universe DFG public | @[email protected] , we are setting up a new tabletop experiment using hollow core PC fiber to search for photon axion mixing.

After years of preparation and work of the team and Le Hoang, we've concluded the first stage of the BRASS experiment arxiv.org/abs/2306.05934 at UHH - MIN-Fakultät Universität Hamburg with support of the Quantum Universe and Max-Planck-Institut für Radioastronomie! Have a look at our hidden photon #DarkMatter sensitivity. More to come

We wanted to understand the interplay of fluorescence and Cherenkov light emission from extended air showers at ultra-large zenith angles. More on this arxiv.org/abs/2305.08710 (accepted for publication) by Ali Baktash from Universität Hamburg - try out the model at github.com/4liBaktash/EAS…

Great news! wissenschaftsrat.de/SharedDocs/Pre… announced the results of their evaluation of the funding requests for new research buildings. Our application Hamburg Fundamental Interactions Laboratory der Universität Hamburg (HAFUN) was ranked first for funding!

Dark Matter around intermediate mass black holes (IMBHS): a fantastic combination for indirect searches. We estimate the number of IMBHs in the Milky Way. You want to know how many there could be? Have a look at our recent paper at JCAP: iopscience.iop.org/article/10.108… open access!
