TOKYO (TIP): Scientists using the ALMA telescope have discovered 15 previously unidentified, extremely dark galaxies buried deeply in cosmic dust. Researchers observed a field named “Subaru/XMMNewtown Deep Survey Field,” located in the direction of the constellation Cetus. As a result, they succeeded in finding 15 extremely dark galaxies that were unidentified until now.
“It is thanks to the high performance of The Atacama Large Millimeter/sub-millimeter Array (ALMA), which is proudly said to be the best in the world, that observations like this have been made possible,” said Bunyo Hatsukade Post-doctoral fellow, Kyoto University. The team successfully measured the number density of galaxies approximately 10 times darker than the millimeter wave research results up to now. The new results agree well with the prediction by the theories of galaxy formation.
