The Dense Plasma Torus Around the Nucleus of an Active Galaxy NGC 1052
S. Kameno, S. Sawada-Satoh, M. Inoue +2
A subparsec-scale dense plasma torus around an active galactic nucleus (AGN) is unveiled. We report on very-long-baseline interferometry (VLBI) observations at 2.3, 8.4, and 15.4 G…
Absolute He polarimetry for a double-chambered cell using transmission of thermal neutrons
A. Watanabe, K. Sekiguchi, T. Ino +5
We present an absolute He polarimetry method based on thermal neutron transmission for a double-chambered cell. This method utilizes the fact that a He nucleus has a large…
Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode
J. C. Algaba, M. Balokovic, S. Chandra +738
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…
On the Near-term Space VLBI Mission VSOP-2
H. Hirabayashi, Y. Murata, P. G. Edwards +6
A second generation near-term space VLBI mission, VSOP-2, is being planned for a launch in 2010 or soon after. The scientific objectives are very high angular resolution imaging of…
Third-order Self-action Effects in Photonic Microcavities
I. Razdolski, R. Kapra, T. Murzina +2
Third-order nonlinear optical effects in photonic microcavities are studied. Significant light defocusing in the thin nonlinear microcavity spacer was observed. The polarization se…
A high-frequency radio survey of low-luminosity active galactic nuclei
A. Doi, S. Kameno, K. Kohno +2
We investigate the high-frequency radio spectra of twenty low-luminosity active galactic nuclei (LLAGNs) with compact radio cores. Our millimetre survey with the Nobeyama Millimetr…
