Welcome to the IceCube and CTA group!
Our group is conducting experimental research activities in high-energy astroparticle physics. Our main research projects include the data analysis of high-energy neutrino events with the IceCube neutrino telescope, and the contribution to the the next generation ground-based VHE gamma-ray instrument named Cherenkov Telescope Array CTA. Specifically, we are involved in the construction and commissioning of the Large Size Telescope (LST), including simulations and first data analysis.
Concerning the first prototypes of Small Size Telescopes, our group created the SST-1M project for the realisation of a single-mirror small-size Cherenkov telescope. The camera of SST-1M was composed of SiPMs, directly designed by our group. The same technology used for the SST-1M project for the photo-detection plane has also been adopted for the "Large High-Altitude Air-Shower Observatory" LHAASO Cherenkov/Fluorescence Telescopes (WFCTA), to which we are collaborating.
Our group also works on other applications of photosensors, and particularly on SiPMs, e.g. in medical diagnostics. In our laboratory, we are equipped with instruments to test the photosensors and their light guides. We are also involved in research projects concerning the study of quantum effects such as the photon entanglement.
Please find here the links to our two main projects: IceCube and CTA.
The IceCube Neutrino Observatory is the world largest particle detector buried in the Antarctic ice located at the South Pole at the depth of 1.5-2.5 km. It is especially tailored to search for neutrinos of energy > 100 GeV from the most violent astrophysical sources: events like exploding stars, gamma ray bursts, and cataclysmic phenomena involving black holes and neutron stars.
Our group contributed significantly to one of the most recent breaktrought papers in IceCube: the 10 year data analysis where we found a significant excess from the source NGC1068 and the TXS 0506+056 evidence from blazar flare oh high energy neutrinos also in confidence with gamma-rays.
The Cherenkov Telescope Array (CTA) project will be the world largest observatory composed by Cherenkov telescopes. This new generation of ground-based very-high-energy gamma-ray instruments will improve notably our capabilities of studying the most extreme phenomena in the Universe.
Our group is part of the worldwide community working on this project, and is mainly involved in the construction and first data analysis of the first telescope of the CTA array, the first Large Size Telescope (LST).
