ALMA uncovers insights into “Golden Age” of galaxy formation

22 September 2016 Astronomy Now

International teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to explore the distant corner of the universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF). These new ALMA observations are significantly deeper and sharper than previous surveys at millimetre wavelengths.


A new record: Keck Observatory measures most distant galaxy

6 August 2015 Astronomy Now

EGSY8p7 is the most distant confirmed galaxy whose spectrum obtained with the W. M. Keck Observatory places it at a redshift of 8.68, at a time when the universe was less than 600 million years old. Hydrogen emission from EGSY8p7 may indicate it is the first known example of an early generation of young galaxies emitting unusually strong radiation.


Ancient quasar with massive black hole found at cosmic dawn

25 February 2015 Astronomy Now

An international team of astronomers has found a huge and ancient black hole which was powering the brightest object in the early universe. The black hole’s mass is 12 billion times that of the Sun, and was at the centre of a quasar that pumped out a million billion times the energy of our star.
