Observation of large scale precursor correlations between cosmic rays and earthquakes
P. Homola, V. Marchenko, A. Napolitano +40
The search for correlations between secondary cosmic ray detection rates and seismic effects has long been a subject of investigation motivated by the hope of identifying a new pre…
Peculiar Radio Structures in the Central Regions of Galaxy Cluster Abell 585
M. Jamrozy, Å Stawarz, V. Marchenko +4
In this paper we analyze the peculiar radio structure observed across the central region of the galaxy cluster Abell 585 (z=0.12). In the low-resolution radio maps, this structure…
NGC 6240 Supermassive Black Hole Binary dynamical evolution based on Chandra data
M. Sobolenko, O. Kompaniiets, P. Berczik +4
The main idea of our research is to estimate the physical coalescence time of the double supermassive black hole (SMBH) system in the centre of NGC 6240 based on the X-ray observat…
Chandra Imaging of the Western Hotspot in the Radio Galaxy Pictor A: Image Deconvolution and Variability Analysis
R. Thimmappa, Å. Stawarz, V. Marchenko +3
Here we present an analysis of the X-ray morphology and flux variability of the particularly bright and extended Western hotspot in the nearest powerful (FR II-type) radio galaxy,…
X-ray Emission of the -ray Loud Young Radio Galaxy NGC 3894
K. Balasubramaniam, L . Stawarz, C. C. Cheung +6
The radio source 1146+596 is hosted by an elliptical/S0 galaxy NGC\,3894, with a low-luminosity active nucleus. The radio structure is compact, suggesting a very young age of the j…
Mid-Infrared Diagnostics of the Circumnuclear Environments of the Youngest Radio Galaxies
E. Kosmaczewski, L. Stawarz, A. Siemiginowska +6
We present a systematic analysis of the mid-infrared (MIR) properties of the youngest radio galaxies, based on low-resolution data provided by the {\it WISE} and {\it IRAS} satelli…
Three-dimensional velocity fields in the silicon- and sulfur-reach ejecta in the remnant of Tycho supernova
O. Petruk, M. Patrii, T. Kuzyo +3
The three-dimensional velocity structure of the shock-heated Si-reach and S-reach ejecta were reconstructed in Tycho supernova remnant from Doppler-shifted lines. The vector compon…
Complex Structure of the Eastern Lobe of the Pictor A Radio Galaxy: Spectral Analysis and X-ray/Radio Correlations
R. Thimmappa, Å. Stawarz, U. Pajdosz-Åmierciak +2
Here we present detailed analysis of the distinct X-ray emission features present within the Eastern radio lobe of the Pictor A galaxy, around the jet termination region, utilising…
Chandra View of the LINER-type Nucleus in the Radio-Loud Galaxy CGCG 292-057: Ionized Iron Line and Jet-ISM Interactions
K. Balasubramaniam, L. Stawarz, V. Marchenko +5
We present an analysis of the new, deep (94\,ksec) {\it Chandra} ACIS-S observation of radio-loud active galaxy CGCG\,292057, characterized by a LINER-type nucleus and a complex…
GeV light curves of young supernova remnants
O. Petruk, V. Beshley, V. Marchenko +1
Observational data from the Fermi Gamma-ray Space Telescope are analyzed with a goal in mind to look for variations in gamma-ray flux from young shell-like supernova remnants. Unif…
Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours
A. Goyal, L. Stawarz, S. Zola +109
We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-ray…
