Constraining the Mass of a Hypothetical Secondary Black Hole in M87 with the NANOGrav 15-Year Data Set
Motoki Kino, Masahiro Nagashima, Hyunwook Ro +3
Galaxy mergers, each hosting a supermassive black hole (SMBH), are thought to form SMBH binaries. Motivated by recent observations from the East Asian VLBI Network (EAVN) showing p…
Mapping the distribution of the magnetic field strength along the NGC 315 jet
Motoki Kino, Hyunwook Ro, Masaaki Takahashi +4
We study magnetic field strengths along the jet in NGC~315. First, we estimated the angular velocity of rotation in the jet magnetosphere by comparing the measured velocity profile…
Precessing jet nozzle connecting to a spinning black hole in M87
Yuzhu Cui, Kazuhiro Hada, Tomohisa Kawashima +76
The nearby radio galaxy M87 offers a unique opportunity to explore the connections between the central supermassive black hole and relativistic jets. Previous studies of the inner…
The Past and Future of East Asia to Italy: Nearly Global VLBI
Gabriele Giovannini, Yuzhu Cui, Kazuhiro Hada +29
We present here the East Asia to Italy Nearly Global VLBI (EATING VLBI) project. How this project started and the evolution of the international collaboration between Korean, Japan…
Transverse Oscillations of the M87 Jet Revealed by KaVA Observations
Hyunwook Ro, Kunwoo Yi, Yuzhu Cui +6
Recent VLBI monitoring has found transverse motions of the M87 jet. However, due to the limited cadence of previous observations, details of the transverse motion have not been ful…
Super-Resolved Image of M87 Observed with East Asian VLBI Network
Fumie Tazaki, Yuzhu Cui, Kazuhiro Hada +11
Obtaining high-resolution images at centimeter-or-longer wavelengths is vital for understanding the physics of jets. We reconstructed images from the M87 22 GHz data observed with…
