An Elaborate Search for Coherent Pulsations from Intermittent-AMXPs
Mustafa Turan Sağlam, Can Güngör, Tuğçe Kocabiyik
We present a detailed systematic pulse search for three Intermittent-Accreting Millisecond X-ray Pulsars (Intermittent-AMXPs), HETE J1900.1-2455, SAX J1748.9-2021 & Aql X-1, via Z$…
Investigation of the Connection Between X-ray Binaries and Compact Star Clusters in NGC 628
Senay Avdan, Aysun Akyuz, Seda Acar +3
We investigated for a possible connection between the types of X-ray binaries (XRBs) and the properties of compact star clusters in the nearby galaxy NGC 628. Using {\it Chandra} a…
Optical Counterparts of ULXs in Two Dwarf Galaxies: NGC 4861 and NGC 4449
M. Ozdogan Ela, A. Akyuz, N. Aksaker +7
We present the results of a search for optical candidates of Ultraluminous X-ray sources (ULXs) in two dwarf galaxies: NGC 4861 and NGC 4449 using Hubble Space Telescope {\it HST}…
The ULX Source X-3 in NGC 4258: A Search for Its X-ray and Optical Properties
A. Akyuz, S. Avdan, S. Allak +3
We present the results of a search for the nature of ultraluminous X-ray source (ULX) X-3 in the nearby galaxy NGC 4258. We use archival data from {\it XMM-Newton}, {\it Chandra},…
Optical Counterparts of ULXs and Their Host Environments in NGC 4490/4485
Senay Avdan, Aysun Akyuz, Alexander Vinokurov +6
We report the identification of the possible optical counterparts of five out of seven Ultraluminous X-ray Sources (ULXs) in NGC 4490/4485 galaxy pair. Using archival Hubble Space…
X-ray Insights into the Nature of Quasars with Redshifted Broad Absorption Lines
Ning-Xiao Zhang, W. N. Brandt, N. S. Ahmed +8
We present observations of seven broad absorption line (BAL) quasars at -2.516 with redshifted BAL troughs (RSBALs). Five of our seven targets were detected by $…
