    • 2018-12-03  Four more detections by the LIGO-VIRGO colaboration

      The National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational-wave detector have published new results from the first two Observing runs. Four new black hole mergers are newly announced, The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions.

      An international team of scientists has found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments in the universe to Earth.

      The observations, made by the IceCube Neutrino Observatory at the Amundsen–Scott South Pole Station and confirmed by telescopes around the globe and in Earth’s orbit, help resolve a more than a century-old riddle about what sends subatomic particles such as neutrinos and cosmic rays speeding through the universe.

      The course was given by Dr. Mauricio Bellini National University of Mar de Plata, Argentina, member of the ANyOG Network, the University Center of Exact Sciences and Engineering, of the University of Guadalajara. The assistants could learn about Chaotic Inflation, Stochastic Inflation and fresh Inflation. A great course where the subjects were exposed and treated in addition to the doubts that arose in addition to the pleasant interaction between Dr. Bellini and the audience.


    • 2017-11-15  Observation of a binary black hole coalescence of 19 solar masses

      On November 15, 2017, LIGO Scientific Collaboration announced the observation of another coalescence of binary black holes. The gravitational waves were observed by the LIGO twin detectors on June 8, 2017. This is the lightest black hole binary observed so far, with component masses 12 and 7 times the mass of the sun, at a distance of about one billion light years from Earth. The fusion left a final black hole 18 times the mass of the sun, which means that energy equivalent to about 1 solar mass was emitted as gravitational waves during the collision.
      This event, detected by the two LIGO detectors compatible with NSF at 02:01:16 UTC on June 8, 2017 (or at 10:01:16 P.M. June 7) at US Eastern Daylight time), It was actually the second binary fusion of black holes observed during LIGO's second observation since it was updated in a program called Advanced LIGO. But his announcement was delayed due to the time required to understand two other discoveries: an observation of three LIGO-Virgo detectors of gravitational waves from another binary black hole fusion (GW170814) on August 14, and the first detection of a binary neutron fusion. stellar (GW170817) in light and gravitational waves on August 17.

      It was held at the University Center of Exact Sciences and Engineering of the University of Guadalajara and the second meeting of the ANyOG Network, where national and international researchers from the Network and invited from LSC LIGO and National Center for Supercomputing Applications participated, where they presented impressive research work to promote students and close collaboration among assistant researchers. At the same time, he took the course of data analysis techniques for gravitational wave detection taught by Dr. Malik Rahkmanov and Dr. Mauricio Antelis.


    • 2017-10-16  The first observation of gravitational waves of neutron stars!

      Por primera vez, los científicos han detectado la forma directa y For the first time, scientists have detected the direct and simultaneous form of gravitational waves - ripples in spacetime - and light from a spectacular collision of two neutron stars. This is the first time that a cosmic event has been observed in both gravitational waves and light. The discovery has been made using the Observatory of Gravitational Waves by Interferometry (LIGO, for its acronym in English) located in the US, the Virgo detector located in Europe, and about 70 terrestrial and space observatories. Neutron stars are the smallest and densest known stars and are formed when the most massive stars explode in the form of supernovas. As the orbits of these stars approached, they emitted gravitational waves that could be detected for about 100 seconds; When colliding, a flash of light was emitted in the form of gamma rays that was observed on Earth about two seconds later than the detection of the gravitational waves themselves

    • 2017-10-06  4th gravitational wave detection!
      The Virgo Collaboration and the LIGO Scientific Collaboration present the first observation of gravitational waves made by three detectors. This is the fourth detection of a binary black hole system and the first significant signal of gravitational wave recorded by the Virgo detector, and highlights the scientific potential of a network of three gravitational wave detectors. The observation of the three detectors took place on August 14, 2017 at 10:30:43 UTC.
      The two gravitational wave detectors by laser interferometry (LIGO), located in Livingston, Louisiana and Hanford, Washington, USA and the Virgo detector, located at the European Gravitational Observatory (EGO) in Cascina, near Pisa, Italy, detected a transient gravitational wave signal produced by the coalescence of two black holes of 31 and 25 solar masses.

    • 2017-06-01  LIGO detects gravitational waves for the third time

      The Observatory of Gravitational Waves by Laser Interferometry (LIGO for its acronym in English) has carried out the third detection of gravitational waves, consolidating the opening of a new astronomical window to the Universe. How in the two previous cases, the waves were generated by the merger of two black holes, which resulted in a third larger. The resulting black hole, located approximately 3 billion light years, has a mass of about 49 times the mass of the Sun. These characteristics place it at an intermediate point between the two previous detections, of 62 and 21 solar masses respectively.
