Gamma Ray Bursts in TV

The TV science series “Astronarium” is broadcasted in the local TV Channel. The episodes are also available on youtube. The episode 14, about the gamma ray bursts, with experts from Center for Theoretical Physics (profs. Agnieszka Janiuk and Lech Mankiewicz) can be seen under this link.

Article about Chaos accepted to A&A

Our article entitled “Chaotic and stochastic processes in the accretion flows of the black hole X-ray binaries revealed by recurrence analysis”, by Petra Sukova, Mikolaj Grzedzielski and Agnieszka Janiuk, has been accepted to Astronomy and Astrophysics. The work describes a novel method for the quantitative analysis of the astrophysical data, to search for the signatures of deterministic chaos process and underlying non-linear hydrodynamics. The latter is connected with the instabilities and limit-cycle type of variability of the black hole accretion disks. Figure below shows an example of the X-ray lightcurve, which we analyzed (RXTE observation of the microquasar’s GX 339-4). Accepted, updated version of the article’s preprint is available under this link.
