Profound optical flares from the relativistic jets of active galactic nuclei
Gopal Bhatta, Staszek Zola, M. Drozdz +11
Intense outbursts in blazars are among the most extreme phenomena seen in extragalactic objects. Studying these events can offer important information about the energetic physical…
Catching profound optical flares in blazars
Gopal Bhatta, Staszek Zola, M. Drozdz +11
Flaring episodes in blazars represent one of the most violent processes observed in extra-galactic objects. Studies of such events shed light on the energetics of the physical proc…
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.…
Discovery of Standstills in the SU UMa-Type Dwarf Nova NY Serpentis
Taichi Kato, Elena P. Pavlenko, Nikolaj V. Pit +40
We found that the SU UMa-type dwarf nova NY Ser in the period gap [orbital period 0.097558(6) d] showed standstills twice in 2018. This is the first clear demonstration of a stands…
Long-period SU UMa dwarf nova V1006 Cygni outburst activity and variability at different brightness states in 2015-2017
E. P. Pavlenko, S. Yu. Shugarov, A. O. Simon +11
CCD photometric observations of the dwarf nova V1006 Cyg were carried out in 2015-2017 with 11 telescopes located at 7 observatories. They covered the 2015 superoutburst with rebri…
Spectroscopic Evidence for Appearance of a New Decretion Disk Around IGR J06074+2205
A. O. Simon, A. V. Bondar, N. V. Metlova
We report about new episode of decretion disk formation in the IGR J06074+2205 system. Obtained spectral data gives us opportunity to measure peak separation in double-peaked Hα li…
