Galaxies in the early Universe (< 2 billion years after the Big Bang or <10% of the current age of the Universe) experience a rapid growth in stellar mass. This goes along with a rapid evolution of their inter-stellar medium properties and physical structure. The mechanisms and physics that lead to this short early growth phase are mostly unknown. We got 70h on the Atacama Large (Sub-) Millimeter Array (ALMA) to study the gas and dust properties of young galaxies during the early growth phase to address these questions.
Greetings from Manchester! Several COSMOS team members are here at the UK ARC node ALMA regional centre this week attending the 'Measuring Star Formation in the Radio, Millimetre and Submillimetre' workshop. We're asking questions like: What is the best way to measure star formation in galaxies? What are the biases involved in our measurements and how can we overcome them? What kind of observations and telescopes do we need in the future to achieve this? We're already well on the way with amazing telescopes like ALMA, JVLA and Herschel and we look forward to the future with JWST, SKA and beyond!
The annual COSMOS team meeting is over for another year! This was the 14th meeting and was held on the 4-7th July at the University of Kyoto in Japan. More than 70 team members from all over Europe, North America and Asia attended the meeting. We heard the latest updates on new data and data products available and new surveys underway, planned exciting future endeavours, and discussed our work on a wide range of science topics including galaxy evolution, the high redshift Universe, large scale structure, active galactic nuclei and the interplay between infrared and radio light. The local organisers did a fantastic job preparing for the week and the meeting was a great success enjoyed by all. We thank them again for all their efforts. We are already looking forward to next year's meeting in Copenhagen! Click below to read more.
COSMOS founder Nick Scoville has been awarded the 2017 Catherine Wolfe Bruce Gold Medal — an honor bestowed by the Astronomical Society of the Pacific (ASP) since 1898 for "a lifetime of outstanding research in astronomy." The COSMOS team would like to congratulate Nick on this well deserved award.
