Event Horizon Telescope observations of the jet launching and collimation in Centaurus A

Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of extragalactic radio jets, down to 10-100 gravitational radii (r_g=GM/c^2) scales in nearby sources. Centaurus A is the closest radio-loud source to Earth. It bridges the gap in... Show more
