An independent hybrid imaging of Sgr A* from the data in EHT 2017 observations
Makoto Miyoshi, Yoshiaki Kato, Junichiro Makino
We propose that the ring structure found by the Event Horizon Telescope Collaboration (EHTC) as the black hole shadow of Sgr A*is an artifact by the bumpy PSF (Point Spread Functio…
Black hole ring images from PSF structures
Makoto Miyoshi, Yoshiaki Kato, Junichiro Makino
Two critical aspects of radio interferometric imaging analysis are data calibration and deconvolution of the point spread function (PSF) structure. Both of these are particularly i…
The jet and resolved features of the central supermassive black hole of M 87 observed with EHT in 2017 -- Comparison with the GMVA 86 GHz results
Makoto Miyoshi, Yoshiaki Kato, Junichiro Makino +1
M 87 is the best target for studying black hole accretion and jet formation. Reanalysis of the EHT public data at 230 GHz shows a core-knots structure at the center and jet feature…
