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.

Constraining Lorentz Invariance Violation Using the Crab Pulsar Emission Observed up to TeV Energies by MAGICSpontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non-trivial dispersion relations for the photon in vacuum. Consequently, gamma-rays of different energies, emitted simultaneously from astrophysical sources, could accumulate measurable differencesMAGIC Collaboration et al.

Observation of the black widow B1957+20 millisecond pulsar binary system with the MAGIC telescopesB1957+20 is a millisecond pulsar located in a black-widow-type compact binary system with a low-mass stellar companion. The interaction of the pulsar wind with the companion star wind and/or the interstellar plasma is expected to create plausible conditions for acceleration of electrons to TeV energies and subsequent production of very high-energyAhnen, M.

MAGIC observations of the microquasar V404 Cygni during the 2015 outburstThe microquasar V404 Cygni underwent a series of outbursts in 2015, June 15-31, during which its flux in hard X-rays (20-40 keV) reached about 40 times the Crab nebula flux. Because of the exceptional interest of the flaring activity from this source, observations at several wavelengths were conducted. The MAGIC telescopes, triggered by theAhnen, M. L. et al.

A Search for Spectral Hysteresis and Energy-dependent Time Lags from X-Ray and TeV Gamma-Ray Observations of Mrk 421Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at different wavelengths, especially in the X-ray and gamma-ray bands, where the broadband spectral energy distributions usually peak.

Observations of Sagittarius A* during the pericenter passage of the G2 object with MAGICContext. We present the results of a multi-year monitoring campaign of the Galactic center (GC) with the MAGIC telescopes. These observations were primarily motivated by reports that a putative gas cloud (G2) would be passing in close proximity to the super-massive black hole (SMBH), associated with Sagittarius A*, located at the center of ourZanin, R. et al.

MAGIC detection of very high energy γ-ray emission from the low-luminosity blazar 1ES 1741+196We present the first detection of the nearby (z = 0.084) low-luminosity BL Lac object 1ES 1741+196 in the very high energy (E > 100 GeV) band. This object lies in a triplet of interacting galaxies.

Very high-energy γ-ray observations of novae and dwarf novae with the MAGIC telescopesContext. In the last five years the Fermi Large Area Telescope (LAT) instrument detected GeV γ-ray emission from five novae. The GeV emission can be interpreted in terms of an inverse Compton process of electrons accelerated in a shock. In this case it is expected that protons in the same conditions can be accelerated to much higher energiesAhnen, M. L. et al.
