A Low-Magnetic-Field Soft Gamma Repeater 2010
YÖKSİS SJR Q1 JCR Q1 OpenAlex top 1% OpenAlex 99.7%
Soft gamma repeaters (SGRs) and anomalous x-ray pulsars form a rapidly increasing group of x-ray sources exhibiting sporadic emission of short bursts. They are believed to be magnetars, that is, neutron stars powered by extreme magnetic fields, B ~ 10(14) to 10(15) gauss. We report on a soft gamma repeater with low ma…

Runaway collisions in young star clusters - II. Numerical results 2006
YÖKSİS SJR Q1 JCR Q1 OpenAlex top 1% OpenAlex 99.1%
We present a new study of the collisional runaway scenario to form an intermediate-mass black hole (IMBH, MBH≳ 100 M⊙) at the centre of a young, compact stellar cluster. The first phase is the formation of a very dense central core of massive stars (M*≃ 30–120 M⊙) through mass segregation and gravothermal collapse. Pr…

The X-Ray Spectrum of the Vela Pulsar Resolved with the [ITAL]Chandra X-Ray Observatory[/ITAL] 2001
OpenAlex top 1% OpenAlex 99.4%
We report the results of the spectral analysis of two observations of the Vela pulsar with the Chandra X-Ray Observatory . The spectrum of the pulsar does not show statistically significant spectral lines in the observed 0.25-8.0 keV band. Similar to middle-aged pulsars with detected thermal emission, the spectrum con…
Charged rotating black holes on a 3-brane 2005
YÖKSİS JCR Q1 OpenAlex top 1% OpenAlex 99.0%
We study exact stationary and axisymmetric solutions describing charged rotating black holes localized on a 3-brane in the Randall-Sundrum braneworld. The charges of the black holes are considered to be of two types, the first being an induced tidal charge that appears as an imprint of nonlocal gravitational effects f…

Crustal Emission and the Quiescent Spectrum of the Neutron Star in KS 1731−260 2002
OpenAlex top 10% OpenAlex 96.8%
The type I X-ray-bursting low-mass X-ray binary KS 1731-260 was recently detected for the first time in quiescence by Wijnands et al. following a τ ob ≈ 13 yr outburst, which ended in 2001 February. We show that the emission area radius for a H atmosphere spectrum (possibly with a hard power-law component that dominat…
A NEW LOW MAGNETIC FIELD MAGNETAR THE 2011 OUTBURST OF SWIFT J1822 3 1606 2012
YÖKSİS SJR Q1 JCR Q1 OpenAlex top 1% OpenAlex 99.5%
We report on the long-term X-ray monitoring with Swift , RXTE , Suzaku , Chandra , and XMM-Newton of the outburst of the newly discovered magnetar Swift J1822.3−1606 (SGR 1822−1606), from the first observations soon after the detection of the short X-ray bursts which led to its discovery, through the first stages of i…
