“IceCube” Observatory provides evidence of neutrinos in the Milky Way for the first time

The “IceCube” Consortium – an international team of researchers – has for the first time provided evidence of the emission of high-energy neutrinos from the Milky Way. The working group headed by Prof. Alexander Kappes from the Institute of Nuclear Physics at Münster University is also involved in the experiment.

IceCube Masterclass in Münster!

Our working group hosts the IceCube Masterclass for another run. Here, pupils can grasp how the experiment detects neutrinos.
With presentations and do-it-yourself experiments, the students will be introduced to the topic. Raffaela Busse, who was a winterover last year, will give insights about the life and work at South Pole. Next, the participants have the opportunity to analyze real IceCube data. At the end, there will be a discussion of the results with other participants from different institutes in form of a video conference, like usually done in big collaborations.
Further information, also about other masterclasses of the Netzwerk Teilchenwelt at the Uni Münster, can be found at For questions contact Lew Classen.

Raffaela Busse back from South Pole!

For one year, our former Master student Raffaela Busse was in charge of the IceCube detector at the Amundsen-Scott South Pole station. Her versatile tasks comprised the maintenance of the complex infrastructure of the detector, the surveillance of the systems for smooth data taking and carrying out special measurements. But better let herself report about her noumerous interesting activities and experiences in her blog:
After vacations in New Zealand she now enriches again our working group while searching for Dark Matter with IceCube data in the framework of her PhD in the RTG 2149 - "Strong and Weak Interactions" . On several occasions, she gives talks about her time at the coldest place on Earth, for example at the Children's University as reported by the WWU.

IceCube LED Modell at exibition in Karlsruhe !

The LED model of IceCube on a scale of 1:1000, build in Münster, was exhibited in an event about particle and astroparticle physics organized by the KIT-Centrum Elementarteilchen- und Astroteilchenphysik (KCETA) in the town hall of Karlsruhe. The model consists of about 5000 separately steerable colored LEDs and alows the display of real IceCube events. Like previously in other routreach events like the Astroseminar of Münster, a huge interest in the model and its experiment was generated.

Premiere! Chasing the Ghost Particle

On Friday the 18th of January the Planetarium in the LWL-Museum für Naturkunde in Münster hosts the premiere of a new film:
„Die Jagd nach dem Geisterteilchen - vom Südpol bis an den Rand des Universums“.
The movie in 360° full-dome format shows information about the experiment and its background at the South Pole.

Source of cosmic neutrinos detected!

The neutrino telescope IceCube has detected a neutrino in coincidence with high-energy gamma radiation for the first time.
The source was determined to be a blazar, a black hole in the center of a far away galaxy emitting a huge amount of mass and radiation in a pointed direction.
Amongst others, the newspaper Westfälische Nachrichten from Münster reported on this discovery.
A detailed article can be found in the Science magazine.

Lew Classen wins the GNN dissertation award!

Our Postdoc Dr Lew Classen was awarded the Global Neutrino Networks (GNN) dissertation prize for his outstanding thesis. With his work on "The mDOM – a multi-PMT digital optical module for the IceCube-Gen2 neutrino telescope" he contributed significantly to the GNN.
Together with Gary Binder of the University of California he recieved the prize in Moscow in October.
Because of that he was mentioned in magazines like the CERN Courier in their November edition, page 36.
We congratulate both for this special accomplishment!
