Broad-band X-ray spectra and timing of the accretion-powered millisecond pulsar Swift J1756.9$-$2508 during its 2018 and 2019 outbursts

no code implementations23 Feb 2021 Z. S. Li, L. Kuiper, M. Falanga, J. Poutanen, S. S. Tsygankov, D. K. Galloway, E. Bozzo, Y. Y. Pan, Y. Huang, S. N. Zhang, S. Zhang

We investigated the temporal, timing and spectral properties of these two outbursts using data from NICER, XMM-Newton, NuSTAR, INTEGRAL, Swift and Insight-HXMT.

A Bayesian Approach to Matching Thermonuclear X-ray Burst Observations with Models

1 code implementation1 Jul 2019 A. J. Goodwin, D. K. Galloway, A. Heger, A. Cumming, Z. Johnston

We infer a neutron star mass of $1. 5^{+0. 6}_{-0. 3}\,\mathrm{M}_{\odot}$ and radius of $11. 8^{+1. 3}_{-0. 9}\,\mathrm{km}$ for a surface gravity of $1. 9^{+0. 7}_{-0. 4}\times10^{14}\,\mathrm{cm}\,\mathrm{s}^{-2}$ for SAX J1808. 4--3658.
