According to a new study, an independent review of the Event Horizon Telescope (EHT) visual data of the elliptical galaxy M87 has produced images with different features. This research is part of a modern scientific process in which observational data and analytical methods are open to the public and reviewed and discussed in various research communities to produce reliable results.

The Elliptical M87 Space Station Radio Data Obtained by Event Horizon Telescope in April 2017 and how the data was analyzed have become accessible worldwide. Researchers not involved in EHT have been re-evaluating this data and methods independently, thus confirming the results presented by EHT. Various groups have published their detailed analysis results in research papers.

A team of researchers comprising Makoto Miyoshi (NAOJ Assistant Professor), Yoshiaki Kato (RIKEN Contract Researcher at the time of the study), and Junichiro Makino (Professor at Kobe University) reviewed M87 data with standard tools and investigated the nature. Be data. Instead of the ring structure seen by EHT, the resulting images show the “spine” in the galactic center, above the plane of the stars from the core, and the “knots” apparently form part of the plane.

Many large black holes produce star jets; this one from the center of the M87 has been known for over 100 years and has been read repeatedly. A team of researchers believes this is the basis for this jet analysis. The team demonstrates that the 40-micro-arcsecond (1 / 25,000th of an arcsecond) ring structure in the EHT image results from insufficient data to resolve 40 micro-arcsecond structures compared to the data. With systems of other sizes, due to the small number of telescopes involved in the EHT experiment then.

Published in the Astrophysical Journal, this study demonstrates the importance of a rational, standard process followed by modern science by teams of independent researchers reviewing observational data and analytical methods. Data analysis, route testing, and systematic tracking monitoring are expected to provide more reliable information on the M87 facility and the explosive flight structure from the galactic center.
