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{…
Ambipolar Heating of Magnetars
Sachiko Tsuruta, Madeline J. Kelly, Ken'ichi Nomoto +3
Magnetars, neutron stars thought to be with ultra-strong magnetic fields of G, are observed to be much hotter than ordinary pulsars with G, and additi…
MXB1659-298: The Fastest Spinning Millisecond Pulsar
Nicholas Kuechel, Marcus Teter, Andrew C. Liebmann +1
We do not present the discovery of strong nearly coherent oscillations (NCOs) at 890.44 Hz for the low mass X-ray binary MXB 1659-298. We find that what we are detecting is dead ti…
X-ray Properties of Hard X-ray Selected AGN
Andrew C. Liebmann, Andrew C. Fabian, Sachiko Tsuruta
Using the latest 70 month Swift-BAT catalog we examined hard X-ray selected Seyfert I galaxies which are relatively little known and little studied, and yet potentially promising t…
