Experimental radio, microwaves and gravitation

Instrumental activity at radio wavelengths involves two, partially overlapping, scientific communities in Italy, with different scientific objectives. Radio astronomy uses, above all, coherent receivers connected to digital electronic systems for the analysis of the converted signal, on ground-based telescopes with ever larger collecting areas. To increase further the baselines of interferometric systems, possible space missions are being studied.

The study of the CMB (Cosmic Microwave Background), that is, the first light in the Universe, is today carried out using coherent (radio), incoherent (bolometers) and cryogenic quantum receivers, for ground-based telescopes, balloons (Boomerang), and space missions (Planck). Lastly, gravitational experiments using radio science are carried out with interplanetary probes, using, above all, precise radio tracking measurements.

Magnetic tornadoes in the Sun’s atmosphere A team of researchers led by Mariarita Murabito (INAF) that includes scientists of the Italian Space Agency (ASI) and the Warwick University has provided the first observational proof that solar tornadoes are produced by swirling magnetic fields

Ultraviolet light vs. COVID19: from the Sun to artificial lamps the germicidal power of ultraviolet rays against the pandemic

Ultraviolet light vs. COVID19: from the Sun to artificial lamps the germicidal power of ultraviolet rays against the pandemic Results of a study carried out by the Italian National Institute for Astrophysics (INAF) and the University of Milan, in collaboration with Istituto Nazionale Tumori and the Don Gnocchi Foundation of Milan, demonstrate the high germicidal power of short ultraviolet radiation (UV-C) on SARS-COV-2 coronavirus. This result has important public health implications on the strategies to be adopted to manage the pandemic and clearly explain how decontamination and sterilization protocols to prevent SARS-Cov-2 infection must be designed. Notably, taking off from these results a second study explains the role of Sun-derived UV-B/A in conditioning the epidemiology and the worldwide evolution of the COVID-19 pandemic
