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…

The quest for planets around subdwarfs and white dwarfs from Kepler space telescope fields: Part I. Techniques and tests of the methods

J. Krzesinski, A. Blokesz, M. Siwak +1

In this study, we independently test the presence of an exoplanet around the binary KIC 9472174, which is composed of a red dwarf and a pulsating type B subdwarf. We also present t…

Signatures of the disk-jet coupling in the Broad-line Radio Quasar 4C+74.26

G. Bhatta, L. Stawarz, A. Markowitz +16

Here we explore the disk-jet connection in the broad-line radio quasar 4C+74.26, utilizing the results of the multiwavelength monitoring of the source. The target is unique in that…
