Photometric study of the star cluster NGC 2155 in the Large Magellanic Cloud: age estimation and variable stars
M. Otulakowska, A. Olech, W. Pych +3
We present results of new photometry for the globular star cluster NGC 2155 in the Large Magellanic Cloud (LMC). Our I- and V-band observations were obtained with the 6.5-meter Mag…
High-energy emission from NGC 5506, the brightest hard X-ray Narrow Line Seyfert 1 galaxy
S. Soldi, V. Beckmann, N. Gehrels +2
We present results on the hard X-ray emission of NGC 5506, the brightest narrow line Seyfert 1 galaxy above 20 keV. All the recent observations by INTEGRAL, Swift and Suzaku have b…
The flare model for X-ray variability of NGC 4258
T. Trzesniewski, B. Czerny, V. Karas +4
We study the variability mechanism of active galactic nuclei (AGN) within the framework of the flare model. To this end we examine the case of Seyfert/LINER galaxy NGC 4258, which…
Variable turbulent convection as the cause of the Blazhko effect - testing the Stothers model
R. Smolec, P. Moskalik, K. Kolenberg +3
The amplitude and phase modulation observed in a significant fraction of the RR Lyrae variables - the Blazhko effect - represents a long-standing enigma in stellar pulsation theory…
Search for Lorentz Invariance breaking with a likelihood fit of the PKS 2155-304 flare data taken on MJD 53944
HESS Collaboration, A. Abramowski, F. Acero +193
Several models of Quantum Gravity predict Lorentz Symmetry breaking at energy scales approaching the Planck scale (10^{19} GeV). With present photon data from the observations of d…
