Experimental gravitation and "Radio Science"

Italy has a strong tradition in the use of interplanetary probes for experiments in the field of gravitation. Taken together, these experiments allow the determination of the gravitational field of the planets and minor bodies of the solar system, their structure and rotational motion, as well as to carry out tests of theories of gravitation: information essential for the study of the origin of the solar system itself.

From the instrumental and know-how point of view, in such "Radio Science" experiments, use is made of high sensitivity accelerometers (the ISA - Italian Spring Accelerometer - is one of the payloads of the Bepi Colombo mission), tracking systems and programmes for accurate orbital determination.

A “cosmic microscope” reveals the origin of galactic winds produced by supermassive black holes

A “cosmic microscope” reveals the origin of galactic winds produced by supermassive black holes By studying a sample of distant galaxies, whose light reaches us from a cosmic epoch when the Universe was just three billion years old, a team of researchers led by Giustina Vietri (INAF) has followed the winds blowing in “active” galaxies down to only a few light-years from the supermassive black holes that sit in the galactic cores
