The scintillating tail of comet C/2020 F3 (Neowise)
Scintillation is a regular software for finding out the intervening ionized medium within the path of radio sources, however it’s normally related to multi-parsec pathlengths. This research brings the software house. The authors used LOFAR observations at 120-180 MHz to probe the ionized part of a comet. Over a four-hour interval, 3C 196, a serendipitously obscured radio galaxy, was handed by comet C/2020 F inside a couple of half diploma of the coma. The authors obtained high-cadence time sequence for dynamical spectra and scintillation energy spectra all through the transit. The scintillation indices are in keeping with robust boundary turbulence the place the tail meets the photo voltaic wind. Comet observations with LOFAR, and finally SKA, ought to yield basic knowledge for comparisons with fashions of plasma and hydrodynamic turbulence in strongly pushed environments.
