Identification of three new ultraluminous X-ray sources in NGC 4631 and NGC 1097: Evidence for stellar-mass black holes
Sinan Allak, Aysun Akyuz, Yasemin Aladag +2
Recent observations of galaxies continue to reveal new ultraluminous X-ray sources (ULXs), increasing their known population and improving the statistics needed to understand their…
Unveiling the nature of donor stars of ULXs in NGC 1559
S. Allak, A. Akyuz
X-ray data provide insights into accretion processes and the compact objects of ultraluminous X-ray sources (ULXs), while optical and infrared (IR) observations help identify the d…
Spectroscopic Observations of Selected Planetary Nebulae from the HASH Database
Utkan Temiz, Nazım Aksaker, Aysun Akyuz
We conducted research on the classification and physical properties of 10 objects from the HASH (Hong Kong/Australian Astronomical Observatory/Strasbourg Observatory H-alpha Planet…
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…
Possible optical counterparts of ULXs in NGC 1672
S. Allak, A. Akyuz, E. Sonbas +1
In this study, we use archival data from HST, Chandra, XMM-Newton, and Swift-XRT, to probe the nature of 9 (X1-X9) candidate ULXs in NGC 1672. Our study focuses on using the precis…
Optical Counterparts of ULXs in NGC 1672
S. Allak, A. Akyuz, E. Sonbas +1
In this work, we deploy archival data from {\it HST}, {\it Chandra}, {\it XMM-Newton}, and {\it Swift-XRT}, to probe the nature of 9 candidate ULXs in NGC 1672. Specifically, our s…
