A 2.1-year periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in almost 7 year of data from the Fermi Large Area Tele…
Broadband characterisation of the very intense TeV flares of the blazar 1ES 1959+650 in 2016
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +164
1ES 1959+650 is a bright TeV high-frequency-peaked BL Lac object exhibiting interesting features like "orphan" TeV flares and a broad emission in the high-energy regime, that are d…
Time-Dependent Modeling of the Sub-Hour Spectral Evolution During the 2013 Outburst of Mrk 421
MAGIC Collaboration, K. Abe, S. Abe +192
In April 2013, the TeV blazar Markarian~421 underwent one of its most powerful emission outbursts to date. An extensive multi-instrument campaign featuring MAGIC, VERITAS, and \tex…
Triple Vector Boson Production at the LHC
D. Green
The interaction among vector bosons is crucial to understanding electroweak symmetry breaking. At the LHC one technique is to use "tag" jets to identify vector boson fusion process…
Proton acceleration in thermonuclear nova explosions revealed by gamma rays
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +208
Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf (WD). Accumulation of hydrogen in a layer eventually causes…
