MAGIC observations of variable very-high-energy gamma-ray emission from PKS1510-089 during May 2015 outburst
Julian Sitarek, Josefa Becerra González, Vandad Fallah Ramazani Elina Lindfors +11
PKS1510-089 is a flat spectrum radio quasar located at a redshift of 0.36. It is one of only a few such sources detected in very-high-energy (VHE, >100 GeV) gamma rays. Though PKS1…

Primary black hole spin in OJ287 as determined by the General Relativity centenary flare
M. J. Valtonen, S. Zola, S. Ciprini +87
OJ287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts which are predictable in a binary black hole model. The model predicted a majo…
