Recent MAGIC results on Galactic binaries

E. Molina, A. López-Oramas, D. Hadasch +1

X-ray and gamma-ray binaries are systems consisting of a compact object and normally a non-degenerate companion star. Most of these sources have been shown to emit radiation in a b…

Origin and role of relativistic cosmic particles

A. Araudo, G. Morlino, B. Olmi +121

This white paper briefly summarizes the importance of the study of relativistic cosmic rays, both as a constituent of our Universe, and through their impact on stellar and galactic…

Observation of inverse Compton emission from a long -ray burst

V. A. Acciari, S. Ansoldi, L. A. Antonelli +301

Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…

Teraelectronvolt emission from the -ray burst GRB 190114C

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +177

Gamma-ray bursts (GRBs) of the long-duration class are the most luminous sources of electromagnetic radiation known in the Universe. They are generated by outflows of plasma ejecte…

Unravelling the complex behavior of Mrk 421 with simultaneous X-ray and VHE observations during an extreme flaring activity in April 2013

MAGIC collaboration, V. A. Acciari, S. Ansoldi +237

We report on a multi-band variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 2013 April 19. The study…

Overview of non-transient gamma-ray binaries and prospects for the Cherenkov Telescope Array

M. Chernyakova, D. Malyshev, A. Paizis +20

We simulate the spectral behaviour of the non-transient gamma-ray binaries using archival observations as a reference. With this we test the CTA capability to measure the sources'…

Multi-wavelength observation of MAXI J1820+070 with MAGIC, VERITAS and H.E.S.S

J. Hoang, E. Molina, M. López +12

MAXI J1820+070 is a new low-mass microquasar hosting a black hole recently discovered in X-rays by the MAXI instrument. It is the counterpart of ASASSN-18ey, discovered in optical…

Insights into the emission of the blazar 1ES 1011+496 through unprecedented broadband observations during 2011 and 2012

J. Aleksić, S. Ansoldi, L. A. Antonelli +161

1ES 1011+496 was discovered in very high energy (VHE, E >100 GeV) -rays with MAGIC in 2007. The absence of simultaneous data at lower energies led to a rather incomp…

The astrometric/morphological variability and the birth place of LS 5039

J. Moldon, M. Ribo, J. M. Paredes

LS 5039 is one of the few X-ray binaries detected at VHE, and potentially contains a young non-accreting pulsar. The outflow of accelerated particles emitting synchrotron emission…

Exploring the powering source of the TeV X-ray binary LS 5039

J. Moldon, M. Ribo, J. M. Paredes +2

LS 5039 is one of the four TeV emitting X-ray binaries detected up to now. The powering source of its multi-wavelength emission can be accretion in a microquasar scenario or wind i…
