Spectral features in gamma-rays expected from millisecond pulsars
T. Bulik, B. Rudak, J. Dyks
In the advent of next generation gamma-ray missions, we present general properties of spectral features of high-energy emission above $1\MeV$ expected for a class of millisecond, l…
Constraints on the Spatial Distribution and Luminosity function of GRBs
Tomasz Bulik
The distance scale to gamma ray bursts has been a subject of scientific debate for almost thirty years. Up to the discovery of afterglows only indirect methods could be used to con…
Distribution of black hole binaries around galaxies
Krzysztof Belczynski, Tomasz Bulik, Wojciech Zbijewski
Compact object mergers are one of the favorite models of GRBs. It has been noted that in opposition to the collapsars, compact object mergers do not necessarily take place in the h…
Modelling blazar radiation spectra Electron injection break and pair content of quasar jets
M. Blazejowski, M. Sikora, R. Moderski +1
We study the dependence of nonthermal radiation spectra in OVV quasars on location of the low energy break in the electron/positron injection function. We show that the high energy…
Keplerian frequencies and innermost stable circular orbits of rapidly rotating strange stars
N. Stergioulas, W. Kluzniak, T. Bulik
It has been suggested that the frequency in the co-rotating innermost stable circular orbit (ISCO) about a compact stellar remnant can be determined through X-ray observations of l…
A BeppoSAX study of the pulsating transient X0115+63: the first X-ray spectrum with four cyclotron harmonic features
A. Santangeo, A. Segreto, S. Giarrusso +9
The recurrent hard pulsating X-ray transient §was observed with \B on March 19, when the source was at a 2--10 keV flux level of 310~mCrab. We report on the high energy spect…
