VLBI Imagings of Kilo-parsec Knot in 3C 380
Shoko Koyama, Motoki Kino, Hiroshi Nagai +3
We investigate observational properties of a kilo-parsec scale knot in radio-loud quasar 3C 380 by using two epoch archival data obtained by Very Long Baseline Interferometry (VLBI…
VLBI Observations of the Jet in M87 During the Very-High-Energy Gamma-ray Flare in April 2010
Kazuhiro Hada, Motoki Kino, Hiroshi Nagai +6
We report on the detailed radio status of the M87 jet during the Very-High-Energy (VHE) gamma-ray flaring event in April 2010, obtained from high-resolution, multi-frequency, phase…
Radio and gamma-ray follow-up of the exceptionally high activity state of PKS 1510-089 in 2011
M. Orienti, S. Koyama, F. D'Ammando +24
We investigate the radio and gamma-ray variability of the flat spectrum radio quasar PKS 1510-089 in the time range between 2010 November and 2012 January. In this period the sourc…
GENJI Programme: Gamma-ray Emitting Notable AGN Monitoring by Japanese VLBI
Hiroshi Nagai, Motoki Kino, Kotaro Niinuma +11
We introduce the GENJI program (Gamma-ray Emitting Notable AGN Monitoring by Japanese VLBI), which is a monitoring program of gamma-ray bright AGNs with the VERA array (VLBI Explor…
Possible Detection of Apparent Superluminal inward motion in Markarian 421 after the Giant X-ray flare in February, 2010
K. Niinuma, M. Kino, H. Nagai +7
We report on the VLBI follow-up observations using the Japanese VLBI Network (JVN) array at 22 GHz for the largest X-ray flare of TeV blazar Mrk 421 that occurred in mid-February,…
