Annually, several billions of particle interactions are detected in the ATLAS experiment at the LHC at CERN. These events are processed, analyzed, and even larger simulated data samples are generated for them. To track the location of each event record and also to be able to search for and retrieve specific events during in-depth investigations, the ATLAS EventIndex catalogue has been compiled. The EventIndex project results have been recently published in a high-ranking scientific journal Computing and Software for Big Science.

The article of the Baikal-GVD collaboration has been published in the authoritative science journal Physical Review D. The first results of the search for astrophysical neutrinos based on the data accumulated by Baikal-GVD, the Baikal Deep Underwater Neutrino Telescope, were announced. The astrophysical neutrino flux earlier detected by the Antarctic Neutrino Telescope IceCube was confirmed. The Baikal Neutrino Telescope is one of the Russian projects at the mega science level. The Baikal-GVD Telescope was ceremonially launched in March 2021 with the participation of the Minister of Higher Education and Science of the Russian Federation Valery Falkov.

A new species of extremophilic bacteria has been isolated by JINR scientists, along with their colleagues from INR of RAS, from subsurface water in an unused tunnel of the Baksan Neutrino Observatory of INR of RAS. The species is able to withstand high concentrations of heavy metals and to grow using C1 compounds as a carbon source. In the long term, this bacterial species can be used to purify soils and waste water from heavy metals and also to recover biomass using an inexpensive carbon source methanol.

In the fall, DLNP JINR scientists returned to the Gran Sasso National Laboratory (Italy) to continue the installation of enriched Ge-76 detectors in the LEGEND experiment. The preparatory work necessary for a full-scale launch of the experiment was carried out. This was followed by reassembly of the liquid argon instrumentation and all currently available detectors made from Ge-76. All operations were performed with the direct participation of our specialists.

Scientists from the Joint Institute for Nuclear Research (JINR, Dubna), along with specialists from the Limnological Institute of the Siberian Branch of the Russian Academy of Sciences (LI SB RAS, Irkutsk) and from the University of Bucharest (Romania), have examined elemental composition of Baikal sponges collected in areas with different anthropogenic load. It turned out that sponges can be successfully used as bioindicators of toxic element pollution in Lake Baikal. The results were published in the journal Marine Pollution Bulletin.

The Daya Bay Reactor Neutrino Experiment has produced the most precise measurement yet of θ₁₃, a key parameter for understanding how neutrinos change their “flavor”.

“It has long been known that there are ultrahigh-energy neutrinos coming to us from space. However, it is the first time we have succeeded in linking them to galactic nuclei, blazars”, Valery Rubakov, the chief researcher of the Institute for Nuclear Research of the Russian Academy of Sciences (INR of RAS), academician of RAS, talked about the main results of the project “Neutrino and particle astrophysics”.

The Neutrino Telescope at Lake Baikal has detected a signal from a radio blazar flare On 8 December 2021, scientists from the IceCube Neutrino Observatory at the South Pole announced the observation of a track, a candidate for the astrophysical neutrino with an estimated energy of about 172 TeV. One of the brightest radio blazars in the sky, PKS 0735+17, is located in the region where the neutrino was presumably born (considering the direction of the incoming particle). The event stands out since this is the most powerful radio blazar flare in the gamma and visible ranges in the entire history of observations of this blazer. Also, its X-ray brightness increased, and the radio burst started. The coincidence between neutrino detection time and such a powerful blazar flare is the second one in the entire history of IceCube observations.

On 19 October 2021, at 15:46, a milestone event for the ATLAS collaboration happened after an almost three-year upgrade break ― the first collision events between proton beams and collimators were recorded during the planned testing of the detector and the accelerator in preparation for the 2022 restart.
