Discovery of TeV -ray emission from the neighbourhood of the supernova remnant G24.7+0.6 by MAGIC

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +151

SNR G24.7+0.6 is a 9.5 kyrs radio and -ray supernova remnant evolving in a dense medium. In the GeV regime, SNR G24.7+0.6 (3FHL\,J1834.1--0706e/FGES\,J1834.1--0706) shows a hard…

Constraining very-high-energy and optical emission from FRB 121102 with the MAGIC telescopes

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +155

Fast radio bursts (FRBs) are bright flashes observed typically at GHz frequencies with millisecond duration, whose origin is likely extragalactic. Their nature remains mysterious,…

The broad-band properties of the intermediate synchrotron peaked BL Lac S2 0109+22 from radio to VHE gamma rays

MAGIC Collaboration, S. Ansoldi, L. A. Antonelli +163

The MAGIC telescopes observed S2 0109+22 in 2015 July during its flaring activity in high energy gamma rays observed by Fermi-LAT. We analyse the MAGIC data to characterise the ver…

Testing the magnetar scenario for superluminous supernovae with circular polarimetry

Aleksandar Cikota, Giorgos Leloudas, Mattia Bulla +15

Superluminous supernovae (SLSNe) are at least 5 times more luminous than common supernovae (SNe). Especially hydrogen-poor SLSN-I are difficult to explain with conventional p…

The detection of the blazar S4 0954+65 at very-high-energy with the MAGIC telescopes during an exceptionally high optical state

MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +169

The very-high-energy (VHE, GeV) -ray MAGIC observations of the blazar S4 0954+65, were triggered by an exceptionally high flux state of emission in the optical. Th…
