The radio galaxy M87 is the central dominant galaxy of the Virgo Cluster. Very high-energy (VHE, ≳0.1 TeV) emission from M87 has been detected by imaging air Cherenkov telescopes. Recently, marginal evidence for VHE long-term emission has also been observed by the High Altitude Water Cherenkov Observatory, a gamma-ray and cosmic-ray detector array located in Puebla, Mexico. The mechanism that produces VHE emission in M87 remains unclear. This emission originates in its prominent jet, which has… 



Modeling the non-flaring VHE emission from M87 as detected by the HAWC gamma ray observatory

M87 is a giant radio galaxy located in the Virgo Cluster, known to be a very high energy (VHE) gamma-ray source. As radio galaxies are considered the misaligned low-redshift counterparts of blazars,

Very High Energy Gamma-Ray Observations of Strong Flaring Activity in M87 in 2008 February

M87 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

Superluminal Radio Features in the M87 Jet and the Site of Flaring TeV Gamma-Ray Emission

Superluminal motion is a common feature of radio jets in powerful γ-ray-emitting active galactic nuclei. Conventionally, the variable emission is assumed to originate near the central supermassive

Monitoring of the radio galaxy M 87 during a low-emission state from 2012 to 2015 with MAGIC

M 87 is one of the closest (z = 0.004 36) extragalactic sources emitting at very high energies (VHE, E > 100 GeV). The aim of this work is to locate the region of the VHE gamma-ray emission and to

High-energy emission processes in M87

We study the contribution of thermal and non-thermal processes to the inverse Compton emission of the radio galaxy M87 by modelling its broad-band emission. Through this we aim to derive insight into

MAGIC observations of the giant radio galaxy M 87 in a low-emission state between 2005 and 2007

Context. We present the results of a long M 87 monitoring campaign in very high energy.-rays with the MAGIC-I Cherenkov telescope. Aims. We aim to model the persistent non-thermal jet emission by

Hard X-Ray Emission from the M87 AGN Detected with NuSTAR

M87 hosts a 3–6 billion solar mass black hole with a remarkable relativistic jet that has been regularly monitored in radio to TeV bands. However, hard X-ray emission ≳10 keV, which would be expected

Modelling TeV γ-ray emission from the kiloparsec-scale jets of Centaurus A and M87

The widespread detection of synchrotron X-ray emission from the jets of low-power, nearby radio galaxies implies the presence of electrons at and above TeV energies. In this paper we explore the

Complex gamma-ray behavior of the radio galaxy M 87

Context. In recent years, non-blazar active galactic nuclei (AGN) such as radio galaxies have emerged as a highly instructive source class providing unique insights into high energy acceleration and

A lepto-hadronic model for high-energy emission from FR I radiogalaxies

Context. The well known radiogalaxy Cen A has been recently detected as a source of very high energy (VHE) γ-rays by the HESS experiment just before Fermi/LAT detected it at high energies (HE). The
