APC – AstroCeNT annual meeting 2022
In early December 2022, an AstroCeNT delegation (group leaders, postdocs, PhD students and administration) traveled to Paris to attend the annual meeting with the Laboratoire Astroparticule & Cosmologie, a scientific partner of the AstroCeNT.
For the past two years, meetings of the two institutions have been held remotely due to Сovid-19 restrictions. This year we managed to get together in large numbers and meet in person.
During the meeting, 15 reports on the progress of the working groups and ongoing projects were presented.
Travel of our scientists to Paris was supported by DarkWave and COPIN grants.
Minister Rzymkowski visits AstroCeNT
On the 1st of June 2022 AstroCeNT was visited by Dr Tomasz Rzymkowski, Vice Minister of Education and Science. The purpose of the visit of our distinguished guests was twofold: to learn more about the field of particle astrophysics, including the research done at AstroCeNT, and to meet with an initiative group to build in Poland an underground laboratory.
The Vice Minister showed much interest in the initiative and encouraged the group to produce a report with more information about possible sites and about the role that the Polish underground laboratory could play in Polish science and economy, both locally and an international level.
Seismic Sensors group activity
The seismic sensors group (led by Prof. Tomasz Bulik) activities revolve mainly around the gravitational waves theme of the Astrocent project. A detection of gravitational waves in 2015 was a great achievement and led to the opening of gravitational wave astronomy. The advancement of this new branch of particle astrophysics hinges on development and improvement of detectors. The quality of the data is related to monitoring and compensating for a variety of sources of noise. The seismic noise, apart from shaking the test masses in the interferometers, is also a source of the Newtonian – or gravity gradient – noise. This type of noise is due to fluctuations of the local gravity by seismic or sound waves in the medium surrounding the detector.
Ultrapure SiPMs and Associated Readout Electronics group activity
One key physics goal is to use dedicated systems of SiPMs to look for the elusive dark matter in the Universe. In order to achieve extreme sensitivity of detectors, its components themselves must not generate any background that could potentially obscure the signal from dark matter. Another important physics goal is the search for so-called Majorana neutrinos. A similar detection technology enables us to look for this potential feature of neutrinos, which could shed lights on the reasons for why our Universe is mostly made up of matter and not antimatter.
Particle Astrophysics Group activity
The Particle Astrophysics research group deals primarily with a wide range of physics questions, both theory and experiment. In line with the general agenda of Astrocent, the main areas of research are:
– dark matter;
– gravitational waves.
To date, four postdoc researchers are working in this group under the guidance of Professor Leszek Roszkowski.
