For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the use of standard candles, celestial events of the same luminosity ...

There's always a touch of melancholy when a chapter that has absorbed years of work comes to an end. In the case of the Atacama Cosmology Telescope ...
