Telescope targets enigmatic deep space mystery
... a model for the average electron density as a function of redshift, enables one to measure the time of flight of the photon, and hence the path length. In this sense, FRBs represent cosmic rulers. Mysteries surrounding FRBs The...

Japan’s Astro-H mission due to launch on February 12, 2016
...Calorimeter is an array of microcalorimeter detectors at the focus of a large X-ray telescope that converts the energy of an X-ray photon (captured by the detectors) into heat, which can then be read by a thermometer.The heat is directly proportional...
