Classification of X-ray Binaries in NGC 6946 with the use of Multiwavelength Data

Senay Avdan, Hasan Avdan, Eda Sonbas +1

We identified X-ray binary (XRB) candidates in the galaxy NGC 6946 using archival {\it Chandra} data. A total of 98 XRB candidates were detected within the 0.38 keV energy range…

X-ray to Mid-IR Spectral Energy Distributions: A Catalog of X-ray Selected AGNs in the XMM-COSMOS Survey

Şeyda Şen, Eda Sonbas, Ece Kilerci +4

We present a component-resolved analysis of the IR--X-ray connection in a sample of 104 spectroscopically confirmed Type~1 AGN. By combining \xmm, \swift/UVOT, and new high--angula…

The Bright X-Ray Source in NGC 3413

E. Sonbas, K. S. Dhuga, E. Göğüş

The emission-line dwarf galaxy NGC 3413 is known to host a bright X-ray source near its optical center. The 0.3-10 keV luminosity of this source is estimated to be approximately 10…

Probing Curvature Effects in the Fermi GRB 110920

A. Shenoy, E. Sonbas, C. Dermer +7

Curvature effects in Gamma-ray bursts (GRBs) have long been a source of considerable interest. In a collimated relativistic GRB jet, photons that are off-axis relative to the obser…

Study of Envelope Velocity Evolution of Type Ib-c Core-Collapse Supernovae from Observations of XRF 080109 / SN 2008D and GRB 060218 / SN 2006aj with BTA

A. S. Moskvitin, E. Sonbas, V. V. Sokolov +2

Results of modeling the spectra of two supernovae SN 2008D and SN 2006aj related to the X-ray flash XRF 080109 and gamma-ray burst GRB / XRF 060218, respectively, are studied. The…
