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.

Light in Astronomy 2017

Nov 14, 2017

Light in Astronomy 2017 Light in Astronomy, organized by INAF in collaboration with the Italian Astronomical Society-SAIt, will be a week (13-19 November) dedicated to satisfying curiosity about the Universe thanks to the opening in Italy of INAF premises, including the astronomical observatories.

Marsis radar reveals that on Mars all that echoes is not ice

Marsis radar reveals that on Mars all that echoes is not ice The low dielectric constant of the Meridiani Planum deposits is consistent with a thick layer of ice-free, porous, basaltic sand. This study is fundamental to identify techniques that may help find the planet’s areas with accessible water ice.

A 3D step towards sorting out the Gamma-Ray Bursts zoo
