Fast radio bursts might come from nearby stars

Fast radio bursts might come from nearby stars

December 16, 2013

Although their characteristics suggested fast radio bursts came from distant galaxies, new research points to origins from flaring stars within the Milky Way. Read Full Astronomy.com article: http://www.astronomy.com/news/2013/12/fast-radio-bursts-might-come-from-nearby-stars

Shep Doeleman: Imaging Black Holes with The Event Horizon Telescope

November 19, 2013

Recent technical advances and observations have now demonstrated that the goal of making an image of a black hole is within reach. Using the technique of Very Long Baseline Interferometry (VLBI), in which widely separated radio dishes are linked together to form an Earth-sized array, our group has succeeded in confirming event horizon scale structures in two super massive black holes: Sagittarius A*, the 4 million solar mass black hole at the center of the Milky Way (Nature, 455, 78, '08), and M87, a 6 billion solar mass black hole in the giant elliptical galaxy Virgo A (Science, 338, 355 Read more about Shep Doeleman: Imaging Black Holes with The Event Horizon Telescope

The Evolving Physical Processes in Interacting Galaxies Traced by Their Spectral Energy Distributions

Mergers and interactions have profound effects on the evolution of galaxies and on the various physical processes associated with star formation and the fueling of active nuclei (AGN). There remains, however, an incomplete understanding of how interactions affect such processes or how important they are in controlling the appearance of today's universe.  Recent Harvard grad Lauranne Lanz for her thesis successfully completed a multi-band analyses (GALEX-Herschel) of set of 31 Read more about Howard Smith: The Evolving Physical Processes in Interacting Galaxies Traced by Their Spectral Energy Distributions

Galaxy Quest: Just How Many Earth-Like Planets Are Out There?

November 5, 2013

A team of planet hunters estimates that about 22 percent of the Sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable. That's the conclusion of a new analysis by Erik Petigura, a graduate student at the University of California, Berkeley of observations taken by NASA's Kepler Space Telescope, which was launched in 2009 to hunt for potentially habitable Earth-like planets around other stars.
