Spitzer Observations of the Predicted Eddington Flare from Blazar OJ 287
Seppo Laine, Lankeswar Dey, Mauri Valtonen +25
Binary black hole (BH) central engine description for the unique blazar OJ 287 predicted that the next secondary BH impact-induced bremsstrahlung flare should peak on 2019 July 31.…
Characterization of a dual-beam, dual-camera optical imaging polarimeter
Manisha Shrestha, Iain A. Steele, Andrez S. Piascik +3
Polarization plays an important role in various time-domain astrophysics to understand the magnetic fields, geometry, and environments of spatially unresolved variable sources. In…
Monitoring of the radio galaxy M87 during a low emission state from 2012 to 2015 with MAGIC
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +188
M87 is one of the closest (z=0.00436) 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 emi…
Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017
F. D'Ammando, C. M. Raiteri, M. Villata +94
We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…
The beamed jet and quasar core of the distant blazar 4C 71.07
C. M. Raiteri, M. Villata, M. I. Carnerero +5
The object 4C 71.07 is a high-redshift blazar whose spectral energy distribution shows a prominent big blue bump and a strong Compton dominance. We present the results of a two-yea…
Accretion Disk Parameters determined from the great 2015 flare of OJ 287
Mauri J. Valtonen, Staszek Zola, Pauli Pihajoki +17
In the binary black hole model of OJ 287 the secondary black hole orbits a much more massive primary, and impacts on the primary accretion disk at predictable times. We update the…
