Donning pointe shoes and a poufy pink tutu, Xiaohan Wu gracefully leaps across the marled dance floor. She stoops, collects an intricate hand fan and proceeds to twirl, delicately waving the fan back and forth as she spins.
Call it a gut reaction. The revolutionary discovery of space-time ripples may have come from two black holes colliding while inside the belly of an enormous star, whose subsequent collapse launched powerful jets of gamma rays.
Einstein's general theory of relativity predicts the emission of gravitational waves by massive celestial bodies moving though space-time. For the past century gravitational waves have eluded a direct detection, but now the LIGO Virgo Collaboration has announced the first direct detection of gravitational waves, emitted by a merging pair of black holes. Catastrophic mergers of binary systems can also produce brilliant and explosive fireworks of light, so a team of astronomers, including at Harvard, sought evidence of such an visible afterglow. Although none was spotted, this work...
Meet Moiya McTier, recipient of the 2016 Chambliss Student Achievement Award. This award is granted every year by the American Astronomical Society (AAS) to recognize exemplary research by undergraduate and graduate students. Moiya is currently a senior at Harvard University. She won this award for her work on determining exoplanet habitability using orbital eccentricity. She conducted this research last summer, when she was a member of the Harvard Banneker Institute. This work ties directly to...
