Two-dimensional Light Beam Shape Characterization using Interferometric Closure Amplitudes
Nithyanandan Thyagarajan, Bojan Nikolic, Chris Carilli +2
We introduce a novel technique using closure amplitudes, inspired by radio interferometry, to determine with high angular resolution the two-dimensional profile of a light beam usi…

A multi-wavelength test of the FR~I - BL Lac unifying model
E. Trussoni, A. Capetti, A. Celotti +2
We collect multi-wavelength measurements of the nuclear emission of 20 low luminosity FR I radio-galaxies to test the viability of the FR I - BL Lac unifying model. Although poorly…
