Published in 2018 at "Scientific Reports"

DOI: 10.1038/s41598-018-24755-8

Abstract: Human deep space and planetary travel is limited by uncertainties regarding the health risks associated with exposure to galactic cosmic radiation (GCR), and in particular the high linear energy transfer (LET), heavy ion component. Here… read more here.

Published in 2018 at "Chinese Physics C"

DOI: 10.1088/1674-1137/42/7/075103

Abstract: More than fifty years after the discovery of the knee in the cosmic ray spectra, its physical origin remains a mystery. This is partly due to the ambiguity of the energy spectrum of individual composition.… read more here.

Published in 2023 at "Science advances"

DOI: 10.1126/sciadv.adg6936

Abstract: Kuiper Belt objects exhibit a wider color range than any other solar system population. The origin of this color diversity is unknown, but likely the result of the prolonged irradiation of organic materials by galactic… read more here.

Published in 2017 at "Geomagnetism and Aeronomy"

DOI: 10.1134/s0016793217050103

Abstract: This work represents a physical interpretation of cosmic ray modulation in the 22nd–24th solar cycles, including an interpretation of an unusual behavior of their intensity in the last minimum of the solar activity (2008–2010). In… read more here.
