An independent hybrid imaging of Sgr A* from the data in EHT 2017 observations – publication

1 mei 2024

1st image of our Milky Way’s black hole may be inaccurate, scientists say.

What does the supermassive black hole lurking at the center of our galaxy look like? It’s a deceptively simple question. Although our local cosmic abyss, named Sgr A* (short for Sagittarius A*), resides just 26,000 light-years from Earth, it has proven to be a very difficult object to image. This is thanks in part to material whipping around it at near light-speeds. However, after years of trying, scientists with the Event Horizon Telescope (EHT) project succeeded in 2022.The black hole’s silhouette emerged from the shadows, appearing like a fuzzy orange doughnut. Yet now, an independent analysis of the EHT data suggests part of the image’s doughnut-like appearance may be an artifact due to the way it was put together. This discovery owes itself to  a trio of scientists at the National Astronomical Observatory of Japan (NAOJ).
