VLBI observations at 147 GHz

01/01/2003View on timeline

Abstract

At 147 GHz (2 mm wavelength), we detected three prominent AGN (NRAO 150, 3C 279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only ∼ 18 micro-arcseconds. This is a new world record in radio interferometry and astronomical imaging and opens fascinating future possibilities to directly image and study the innermost regions in Quasars and other Active Galactic Nuclei.
