Quasi-Periodic Oscillations in Gamma-Ray Bursts' Prompt Light Curves
Mariusz Tarnopolski
I report on the discovery of 34 new quasi-periodic oscillations (QPOs) in the prompt light curves of long gamma-ray bursts (GRBs) from the Swift/BAT catalog: with one or more const…
Comprehensive power spectral density analysis of the Fermi-LAT -ray light curves of selected blazars
Natalia Żywucka, Mariusz Tarnopolski, Volodymyr Marchenko +1
We present the results of the Fermi-Large Area Telescope (LAT) light curve (LC) modelling of selected blazars: six flat spectrum radio quasars (FSRQs) and five BL Lacertae (BL Lacs…
Graph-based clustering of gamma-ray bursts
Mariusz Tarnopolski
Aims. An attempt to classify gamma-ray bursts (GRBs) with a low level of supervision using the state-of-the-start approaches stemming from graph theory was undertaken. Methods. Gra…
How does the shape of gamma-ray bursts' pulses affect the duration distribution?
Mariusz Tarnopolski
Gamma-ray bursts (GRBs) come in two types, short and long. The distribution of logarithmic durations of long GRBs is asymmetric rather than Gaussian. Such an asymmetry, when modell…
A Comprehensive Power Spectral Density Analysis of Astronomical Time Series. II. The Swift/BAT Long Gamma-Ray Bursts
Mariusz Tarnopolski, Volodymyr Marchenko
We investigated the prompt light curves (LCs) of long gamma-ray bursts (GRBs) from the Swift/BAT catalog. We aimed to characterize their power spectral densities (PSDs), search for…
Searching for signatures of chaos in gamma-ray light curves of selected Fermi-LAT blazars
O. Ostapenko, M. Tarnopolski, N. Żywucka +1
Blazar variability appears to be stochastic in nature. However, a possibility of low-dimensional chaos was considered in the past, but with no unambiguous detection so far. If pres…
