ALMA Result Reveals Starving Galaxies

Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into ‘red and dead’ elliptical galaxies, catching a large group of galaxies right in the middle of this change. According to lead investigator Dr. Carol Lonsdale of the North American ALMA Science Center at the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, despite ALMA’s great sensitiviy to detecting starbursts, they saw nothing, or next to nothing, which is exactly what they hoped it would see. For these observations, ALMA was tuned to look for dust warmed by active star-forming regions.
