Modelling of the non-thermal emission from inhomogeneous jets in active galactic nuclei
(2018)Some active galactic nuclei (AGNs) are strong sources of non-thermal radiation. It is expected that this radiation is produced in collimated outflows of plasma moving with relativistic speeds, the so-called jets. The ... -

Superaktywacja nierówności Svetlichnego w układach wielocząstkowych
(2017)Rozprawa doktorska obejmuje analizę aktywacji łamania nierówności Svetlichnego w układach trzycząstkowych zarówno dla stanów czystych jak i dla mieszanych stanów zaszumionych. W ostatnich latach nielokalne korelacje ... -
The X/gamma-ray correlation in NGC 4945 and the nature of its gamma-ray source
(IOP Publishing for the American Astronomical Society, 2017)We report hints for the correlation between the X-ray and gamma-ray emission in the nearby galaxy NGC 4945, which harbors both an active galactic nucleus and a nuclear starburst region. We have divided the Fermi/LAT ... -
X-ray/γ-ray Correlation in Seyfert 2 Galaxy NGC 4945
(AIP Conference Proceedings - American Institute of Physics, 2017-01-04)We report the correlation between the X-ray and γ-ray emission found in our analysis of the Fermi/LAT and Swift/BAT data from 8 years of observations of the nearby Seyfert 2 galaxy NGC 4945. Using the BAT light-curves we ... -
Generalized Niederer’s transformation for quantum Pais–Uhlenbeck oscillator
(Elsevier B.V., 2015)We extend, to the quantum domain, the results obtained in [Nucl. Phys. B 885 (2014) 150] and [Phys. Lett. B 738 (2014) 405] concerning Niederer’s transformation for the Pais–Uhlenbeck oscillator. Namely, the quantum ... -
Elastic scattering in geometrical model
(Elsevier B.V., 2016)The experimental data on proton–proton elastic and inelastic scattering emerging from the measurements at the Large Hadron Collider, calls for an efficient model to fit the data. We have examined the optical, geometrical ... -
Badanie wybranych właściwości i zastosowań zawiesin magnetoreologicznych
(2015)Praca składa się z pięciu rozdziałów. Pierwszy rozdział stanowi wprowadzenie, w którym przestawiono nazewnictwo, genezę i w zarysie najważniejsze właściwości oraz kierunki zastosowań dyspersyjnych materiałów ferromagnetycznych ... -
β decay of 6He into the α+d continuum
(American Physical Society, 2015)The rare β-decay channel of 6He into the α+d continuum was investigated at the REX-ISOLDE facility. Bunches of postaccelerated 6He ions were implanted into the optical time projection chamber (OTPC), where the decays with ... -
Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory
(Springer Berlin Heidelberg, 2014)Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E≥6×10^19 eV by ... -
Photoproduction of isolated photons, inclusively and with a jet, at HERA
(Elsevier B.V., 2014)The photoproduction of isolated photons, both inclusive and together with a jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 374 pb^{−1}. Differential cross sections are presented in ... -
Erratum: Measurement of D^{∗±} production in deep inelastic scattering at HERA
(Springer Berlin Heidelberg, 2014)In the analysis for our paper on D* production, the beauty contribution was erroneously subtracted twice in the extraction of the reduced cross sections. This affected tables 9 and 10 as well as figures 9 and 10 that ... -
Further studies of the photoproduction of isolated photons with a jet at HERA
(Springer Science+Business Media on behalf of the Scuola Internazionale Superiore di Studi Avanzati, 2014)In this extended analysis using the ZEUS detector at HERA, the photoproduction of isolated photons together with a jet is measured for different ranges of the fractional photon energy, x_γ^{meas}, contributing to the ... -
Weak n-Ary Relational Products in Allegories
(MDPI AG, 2014)Allegories are enriched categories generalizing a category of sets and binary relations. Accordingly, relational products in an allegory can be viewed as a generalization of Cartesian products. There are several definitions ... -
Measurement of beauty and charm production in deep inelastic scattering at HERA and measurement of the beauty-quark mass
