Exploring the central sub-pc region of the γ-ray bright radio galaxy 3C 84 with the VLBA at 43 GHz in the period of 2002-2008
Kenta Suzuki, Hiroshi Nagai, Motoki Kino +13
Following the discovery of a new radio component right before the GeV γ-ray detection since 2008 August by Fermi Gamma-ray Space Telescope, we present a detailed study of the kinem…
The Structure of the M87 Jet: A Transition from Parabolic to Conical Streamlines
Keiichi Asada, Masanori Nakamura
The structure of the M87 jet, from milli-arcsec to arcsecond scales, is extensively investigated, utilizing the images taken with the EVN, MERLIN and VLBA. We discover that the jet…
Very Long Baseline Array Imaging of Parsec-scale Jet Structures in Radio-loud Narrow-line Seyfert 1 Galaxies
Akihiro Doi, Keiichi Asada, Hiroshi Nagai
We conducted very long baseline interferometry (VLBI) observations of five radio-loud narrow-line Seyfert 1 (NLS1) galaxies in milliarcsecond resolutions at 1.7 GHz (18 cm) using t…
