    Descripción

    El Grupo de Astrofísica de Partículas del IAC participa activamente en tres grandes colaboraciones internacionales de astrofísica de muy altas energías: AMS (Alpha Magnetic Spectrometer), los telescopios de radiación Cherenkov MAGIC I y II, y el Cherenkov Telescope Array (CTA).

    AMS es un detector de partículas diseñado para operar en el espacio, a bordo de la Estación Espacial Internacional. Se instaló con éxito en mayo de 2011, y se espera que opere durante toda la vida útil de la misma. Su misión es realizar un estudio de alta precisión y estadística del espectro y la composición de los rayos cósmicos primarios en un amplio rango de energía, así como buscar antimateria primordial y materia oscura de forma indirecta.

    La colaboración MAGIC está formada por 20 institutos y departamentos universitarios de Alemania, Armenia, Bulgaria, España, EEUU, Finlandia, Italia, Polonia y Suiza. La colaboración cuenta con dos telescopios de 17 m de diámetro localizados en el Obsevatorio del Roque de los Muchachos, diseñados para medir la radiación Cherenkov asociada a cascadas atmosféricas producidas por rayos gamma de muy alta energía y localizados en el Observatorio del Roque de los Muchachos.

    Además de esto, y también en el marco de la observación de rayos gamma de muy alta energia, el IAC participa en la colaboración internacional CTA, cuyo objetivo es construir dos grandes complejos de observación en los hemisferios Norte y Sur. El Observatorio del Roque de los Muchachos, en La Palma, ha sido seleccionado para albergar el observatorio Norte. El primer telescopio de gran diámetro fue inaugurado en octubre de 2018 y actualmente estamos en la fase de construcción de otros tres.

      We report on our observing campaign of the compact binary merger GW190814, detected by the Advanced LIGO and Advanced Virgo detectors on 2019 August 14.

      We report the detection of pulsed gamma-ray emission from the Geminga pulsar (PSR J0633+1746) between 15 GeV and 75 GeV. This is the first time a middle-aged pulsar has been detected up to these energies. Observations were carried out with the MAGIC telescopes between 2017 and 2019 using the low-energy threshold Sum-Trigger-II system. After quality

    • MAGIC observations of the diffuse γ-ray emission in the vicinity of the Galactic center
      Aims: In the presence of a sufficient amount of target material, γ-rays can be used as a tracer in the search for sources of Galactic cosmic rays (CRs). Here we present deep observations of the Galactic center (GC) region with the MAGIC telescopes and use them to infer the underlying CR distribution and to study the alleged PeV proton accelerator

    • Testing two-component models on very high-energy gamma-ray-emitting BL Lac objects
      Context. It has become evident that one-zone synchrotron self-Compton models are not always adequate for very high-energy (VHE) gamma-ray-emitting blazars. While two-component models perform better, they are difficult to constrain due to the large number of free parameters. Aims: In this work, we make a first attempt at taking into account the

      We investigate the physical nature and origin of the gamma-ray emission from the extended source HESS J1841-055 observed at TeV and GeV energies. We observed HESS J1841-055 at TeV energies for a total effective time of 43 h with the MAGIC telescopes, in 2012 and 2013.

      Extreme high-frequency BL Lacs (EHBL) feature their synchrotron peak of the broad-band spectral energy distribution (SED) at ν s ≥ 10 17 Hz. The BL Lac object 1ES 2344+514 was included in the EHBL family because of its impressive shift of the synchrotron peak in 1996.

The situation becomes more favourable in the case of the extreme blazars (EHBLs), for which the bulk of the emission of the relativistic jets is emitted at

      Extreme high-frequency-peaked BL Lac objects (EHBLs) are blazars that exhibit extremely energetic synchrotron emission. They also feature nonthermal gamma-ray emission whose peak lies in the very high-energy (VHE, E > 100 GeV) range, and in some sources exceeds 1 TeV: this is the case for hard-TeV EHBLs such as 1ES 0229+200.
