Pulse profile variations in the accreting X-ray pulsar Vela X-1
V. Madurga-Favieres, A. Martin-Carrillo, C. M. Diez +7
Vela X-1 is a well-studied accreting X-ray pulsar, with a distinctive pulse profile that has been found to be very similar in different observations spread out over decades. On the…
Characterizing the star cluster populations in Stephan's Quintet using HST and JWST observations
P. Aromal, S. C. Gallagher, K. Fedotov +14
Stephan's Quintet (SQ) is a local compact galaxy group system that exhibits significant star formation activity. A history of tidal interactions between its four member galaxies an…
Modeling the High-Energy Ionizing Output from Simple Stellar and X-ray Binary Populations
Kristen Garofali, Antara R. Basu-Zych, Benjamin D. Johnson +9
We present a methodology for modeling the joint ionizing impact due to a "simple X-ray population" (SXP) and its corresponding simple stellar population (SSP), where "simple" refer…
NGC 4388: A Test Case for Relativistic Disk Reflection and Fe K Fluorescence Features
Tahir Yaqoob, P. Tzanavaris, S. LaMassa
We present a new analysis of the Suzaku X-ray spectrum of the Compton-thin Seyfert 2 galaxy NGC 4388. The spectrum above 2 keV can be described by a remarkably simple and rat…
The Complex X-ray Obscuration Environment in the Radio Loud Type 2 Quasar 3C 223
Stephanie M. LaMassa, Tahir Yaqoob, Panayiotis Tzanavaris +4
3C 223 is a radio loud, Type 2 quasar at with an intriguing XMM-Newton spectrum that implicated it as a rare, Compton-thick ( cm$^…
Are Compton-thin AGNs Globally Compton Thin?
P. Tzanavaris, T. Yaqoob, S. LaMassa +2
We select eight nearby AGNs which, based on previous work, appear to be Compton-thin in the line of sight. We model with MYTORUS their broadband X-ray spectra from 20 individual ob…
