Astronomical Pipeline Provenance: A Use Case Evaluation
Michael A. C. Johnson, Marcus Paradies, Marta Dembska +4
In this decade astronomy is undergoing a paradigm shift to handle data from next generation observatories such as the Square Kilometre Array (SKA) or the Vera C. Rubin Observatory…
Gigahertz-peaked spectra pulsars and thermal absorption model
J. Kijak, R. Basu, W. Lewandowski +2
We present the results of our radio interferometric observations of pulsars at 325 MHz and 610 MHz using the Giant Metrewave Radio Telescope (GMRT). We used the imaging method to e…
Time variation in the low frequency spectrum of Vela-like pulsar B1800-21
Rahul Basu, Karolina Rożko, Wojciech Lewandowski +2
We report the flux measurement of the Vela like pulsar B1800-21 at the low radio frequency regime over multiple epochs spanning several years. The spectrum shows a turnover around…
Flux density measurements of GPS candidate pulsars at 610 MHz using interferometric imaging technique
M. Dembska, R. Basu, J. Kijak +1
We conducted radio interferometric observations of six pulsars at 610 MHz using the Giant Metrewave Radio Telescope (GMRT). All these objects were claimed or suspected to be the gi…
Pulse broadening analysis for several new pulsars and anomalous scattering
Wojciech Lewandowski, Marta Dembska, Jaroslaw Kijak +1
We show the results of our analysis of the pulse broadening phenomenon in 25 pulsars at several frequencies using the data gathered with GMRT and Effelsberg radiotelescopes. Twenty…
Binary Pulsar B1259-63 Spectrum Evolution and Classification of Pulsar Spectra
M. Dembska, J. Kijak, W. Lewandowski
Recently published results \citep{kijak2011b} indicated the evidence for a new aspect in radio pulsars spectra. We studied the radio spectrum of PSR B1259-63 in an unique binary wi…
Binary pulsar B1259-63 spectrum evolution: detailed study
Marta Dembska, Jarosław Kijak, Wojciech Lewandowski
We studied the radio spectrum of PSR B1259-63 in an unique binary with Be star LS 2883 and showed that the shape of the spectrum depends on the orbital phase. We proposed a qualita…
Modelling of the radio spectrum evolution in the binary pulsar B125963
M. Dembska, J. Kijak, O. Koralewska +3
In this paper we give the first attempt to model the evolution of the spectrum of PSR B125963 radio emission while the pulsar orbits the companion Be star. As suggested by Kijak…
Food-chain competition influences gene's size
Marta Dembska, M. R. Dudek, D. Stauffer
We have analysed an effect of the Bak-Sneppen predator-prey food-chain self-organization on nucleotide content of evolving species. In our model, genomes of the species under consi…
