Astronomy High-energy neutrino signatures of newborn pulsars in the local universe THE UNIVERSITY OF CHICAGO Angela V. Olinto FangKeCharged particles can be accelerated to higher than PeV energies in the electro-magnetic wind of a fast-spinning newborn pulsar to produce high-energy neutrinos, ...
which are faint and require highly sensitive, precisely calibrated detection methods. Detecting these waves for the first time would not only provide groundbreaking insights into the structure and behavior of neutron stars—among the densest objects in the universe short ofblack holes...
Pulsars— The Universe’s lighthouses; they are extremely dense collapsed cores of massive supergiant stars (called neutron stars) that beam out radio waves, like a lighthouse. As apulsarrotates, we can see a pulse in radio telescopes every time the beam points towards the Eart...
Precise measurement of cosmic rays, especially at the very high energy range, is important for scientists to look for traces of dark matter annihilation or decay, as well as to understand the most energetic astrophysical phenomena in the universe, such as pulsars, active galaxy nuclei and superno...
Which of the following has the Hubble Space Telescope done? a. It has discovered four of Pluto's five moons. b. It has taken never-before-seen images of Pluto. c. It has taken photos of pulsating stars. d. It has helped us find the ages of pulsars. A. ab B. ac C. bc D....
"But we didn't really know what to do with it." Such fleeting radio bursts usually came from pulsars — furiously rotating neutron stars whose radiation sweeps by Earth with the regularity of a lighthouse beam. But Lorimer, an astrophysicist at West Virginia University in Morgantown, saw ...
How do we perceive the link between the Universe in which we all live and Consciousness that we all share? What exactly binds the two together?
Secondly, as the final evolutionary stage for most stars, white dwarfs are plentiful in the universe. Thirdly, their compact nature results in a structure that is highly responsive to the precise value of G. Lastly, the well-understood evolution of white dwarfs can be precisely characterized as...

Other research groupshave found 10 long radio pulse-emitting systems over the past couple of years, and they are trying to determine what creates them because the pulses, all of which originate in the Milky Way, “are unlike anything we knew before,” de Ruiter said. ...
