The observations with ALMA, a research team revealed the
most unidentifiable millimeter wave signals are emitted from galaxies.
A research team led by Bunyo Hatsukade, a postdoc
researcher, and Kouji Ohta, a professor, both from the Graduate School of
Science, Kyoto University, revealed that approximately 80% of the
unidentifiable millimeter wave signals from the universe is actually emitted
from galaxies, based on the observations with ALMA (Atacama Large
Millimeter/submillimeter Array). ALMA’s high resolving power and sensitivity
enables us to pinpoint the locations of those galaxies rich in fine solid
particles (dust).
