Flux Dependence of the 1\,keV Soft X-ray Feature in SAX J1808.4-3658 with \textit{NICER}
Katherine Bruce, Anne M. Lohfink, Jaiverdhan Chauhan +3
We present a systematic X-ray spectral analysis of the 2019 and 2022 outbursts of the accreting millisecond pulsar SAX J1808.4-3658 with extit{NICER} with a particular emphasis on…
Spectral Analysis of the 2019 and 2022 Outbursts of SAX J1808.4-3658
Katherine Bruce, Sachiko Tsuruta, Andrew C. Liebmann +1
The accreting millisecond pulsar SAX J1808.4-3658 went into outburst from July to November in 2019 and August to October in 2022, which were observed by \textit{NICER} and \textit{…
Combined Analysis of X-Ray Spectra of NGC 3227
J. Newman, S. Tsuruta, A. C. Liebmann +2
The 1.5 Seyfert galaxy NGC 3227 has been observed by several X-ray missions. We carried out a combined analysis of the data obtained by more recent major observations of the source…
Effects of Inner Alfvén Surface Location on Black Hole Energy Extraction in the Limit of a Force-Free Magnetosphere
Kevin Thoelecke, Masaaki Takahashi, Sachiko Tsuruta
An energy extracting black hole magnetosphere can be defined by the location of its inner Alfvén surface, which determines the rate of black hole energy extraction along a given ma…
