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…
Can the Cosmological Dilation Explain the Skewness in the Gamma-Ray Burst Duration Distribution?
Mariusz Tarnopolski
In order to explain the origin of skewness in the gamma-ray burst (GRB) duration distribution, a statistical model, based on the cosmological time dilation and taking into account…
Optical variability modeling of newly identified blazar candidates behind Magellanic Clouds
Natalia Żywucka, Mariusz Tarnopolski, Markus Böttcher +2
We present an optical variability study of 44 newly identified blazar candidates behind the Magellanic Clouds, including 27 flat spectrum radio quasars (FSRQs) and 17 BL Lacertae o…
