• Supermassive black holes found in 2 tiny galaxies

  17-04-2017 06:00
  
  (University of Utah) U astronomers and colleagues have found two ultra-compact dwarf galaxies with supermassive black holes, the second and third such galaxies found to harbor the objects. Together, the three examples suggest that black holes lurk at the center of most ultra-compact dwarfs, potentially doubling the number of supermassive black holes known in the universe. The tiny galaxies were likely leftovers of larger galaxies stripped of their outer layers after colliding into other, larger

• Columbia engineers invent method to control light propagation in waveguides

  17-04-2017 06:00
  
  (Columbia University School of Engineering and Applied Science) Columbia Engineering Professor Nanfang Yu has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. He built photonic integrated devices that had record-small footprints and were also able to maintain optimal performance over an unprecedented broad wavelength range. His method could lead to faster, more powerful, and more efficient optical chips, which in tur
