Abstract We propose a method to detect possible non-stationarities of gamma-ray burst jets. Assuming that the dominant source variability in prompt gamma light curve is non-stationarity jet, we show there should be connection between measure and characteristic angle jet derived from break time afterglow. carried out Monte Carlo simulations long observations assuming three radial luminosity density profiles for jets randomizing all parameters, created samples curves by simulating undergoing...
Abstract Recoiling active galactic nuclei (AGNs) can be formed after the merging of two galaxies and their central supermassive black holes. A novel method recently revealed a handful recoiling AGN candidates. We report on arcsec-scale radio structure one them, 4C 18.47, prominent emitter. also present its infrared light curve, indicating significant long-term variability.
In Budai et al. (2020) we argued that angular non-stationarities of gamma-ray burst (GRB) jets can result in a statistical connection between the angle values deduced from jet break times and variabilities prompt light curves. The should be an anti-correlation if luminosity densities follow power-law or uniform profile, correlation they have Gaussian profile. this follow-up paper, search for by measuring Spearman's rank coefficient sample 19 long GRBs observed Swift satellite. Using 16 with...
