1 Jul 2002 | | Subject: | astro-ph | | Affiliation: | MPIfR) A. Greve, M. Grewing (IRAM), S. Doeleman, R. Phillips, A.E.E. Rogers, M. Titus (Haystack), H. Fagg, P. Strittmatter, T.L. Wilson, L. Ziurys (Steward Obs.), R. Freund (NRAO), P. K"on"onen, J. Peltonen, S. Urpo (Metsahovi Radio Obs.), F. | | Abstract: | At 147 GHz (2mm wavelength), we detected three prominent AGN (NRAO150, 3C279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only 18 micro-arcseconds on the baseline between two antennas in Arizona (10m HHT and 12m KittPeak) and the IRAM 30m antenna on Pico Veleta in Spain. 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. | | Source: | arXiv, astro-ph/0207022 | | Services: | Forum | Review | PDF | Favorites | |
