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.

Rapid and multiband variability of the TeV bright active nucleus of the galaxy IC 310Context. The radio galaxy IC 310 has recently been identified as a γ-ray emitter based on observations at GeV energies with Fermi-LAT and at very high energies (VHE, E > 100 GeV) with the MAGIC telescopes. Originally classified as a head-tail radio galaxy, the nature of this object is subject of controversy since its nucleus shows blazar-likeAleksić, J. et al.

Optimized dark matter searches in deep observations of Segue 1 with MAGICWe present the results of stereoscopic observations of the satellite galaxy Segue 1 with the MAGIC Telescopes, carried out between 2011 and 2013. With almost 160 hours of good-quality data, this is the deepest observational campaign on any dwarf galaxy performed so far in the very high energy range of the electromagnetic spectrum.

MAGIC upper limits on the GRB 090102 afterglowIndications of a GeV component in the emission from gamma-ray bursts (GRBs) are known since the Energetic Gamma-Ray Experiment Telescope observations during the 1990s and they have been confirmed by the data of the Fermi satellite. These results have, however, shown that our understanding of GRB physics is still unsatisfactory. The new generationGarcía-López, R. J. et al.

Observations of the magnetars 4U 0142+61 and 1E 2259+586 with the MAGIC telescopesContext. Magnetars are an extreme, highly magnetized class of isolated neutron stars whose large X-ray luminosity is believed to be driven by their high magnetic field. Aims: We study for the first time the possible very high energy γ-ray emission above 100 GeV from magnetars, observing the sources 4U 0142+61 and 1E 2259+586. Methods: We observedBackes, M. et al.

Search for Very High Energy Gamma-ray Emission from Pulsar-Pulsar Wind Nebula Systems with the MAGIC TelescopeThe MAGIC collaboration has searched for high-energy gamma-ray emission of some of the most promising pulsar candidates above an energy threshold of 50 GeV, an energy not reachable up to now by other ground-based instruments. Neither pulsed nor steady gamma-ray emission has been observed at energies of 100 GeV from the classical radio pulsars PSRAnderhub, H. et al.

Very High Energy Gamma-Ray Observations of Strong Flaring Activity in M87 in 2008 FebruaryM87 is the only known nonblazar radio galaxy to emit very high energy (VHE) gamma rays. During a monitoring program of M87, a rapid flare in VHE gamma-rays was detected by the MAGIC telescope in early 2008. The flux was found to be variable above 350 GeV on a timescale as short as 1 day at a significance level of 5.6 σ. The highest measured fluxAlbert, J. et al.

Systematic Search for VHE Gamma-Ray Emission from X-Ray-bright High-Frequency BL Lac ObjectsAll but three (M87, BL Lac, and 3C 279) extragalactic sources detected so far at very high energy γ-rays belong to the class of high-frequency-peaked BL Lac objects. This suggested to us a systematic scan of candidate sources with the MAGIC telescope, based on the Donato et al. compilation of X-ray blazars. The observations took place from 2004Albert, J. et al.
