    Constraining Lorentz Invariance Violation Using the Crab Pulsar Emission Observed up to TeV Energies by MAGIC
    Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non...

    Constraints on the Steady and Pulsed Very High Energy Gamma-Ray Emission from Observations of PSR B1951+32/CTB 80 with the MAGIC Telescope
    We report on very high energy γ-ray observations with the MAGIC Telescope of the pulsar PSR B1951+32 and its associated nebula, CTB 80. Our data constrain the...

    Descubren un sistema estelar binario de tipo “viuda negra” con el periodo orbital más corto registrado hasta ahora
    Mientras que la Tierra tarda 365 días en completar su órbita alrededor del Sol, la estrella que orbita el nuevo púlsar ZTF J1406+1222 lo hace en tan sólo 62...

    Detection of coherent millisecond pulsations at ~518 Hz in the LMXB Swift J1749.4-2807 (GRB060602B)
    On April 10th, it was discovered (ATel #2548) using INTEGRAL that the neutron-star X-ray binary Swift J1749.4-2807 (Wijnands et al. 2009, MNRAS, 393, 126) was...
