TL;DR: In this paper, the authors present a spectral analysis of four persistent atoll sources (GX 3+1, 4U 1702−429 and 4U 0614+091) observed for 20 ks each with NuSTAR to determine the extent of the inner accretion disk.

TL;DR: In this article, the authors present a recent NuSTAR observation of the Z source GX 349+2, which spans approximately 2 days, and covers all its spectral states, and extract five spectra and trace the change in spectral parameters throughout the Z-track.

TL;DR: In this article, the authors present a spectral analysis of four persistent atoll sources (GX 3+1, 4U 1702$-$429 and 4U 0614+091) observed for $20$ ks each with NuSTAR to determine the extent of the inner accretion disk.

TL;DR: In this paper, the authors used relativistic ray-tracing functions and applied them to archival RXTE data on 4U 1728-34 where upper kHz QPOs have been detected, determining the reflected flux fraction across all energies and produce a model for the lag-energy spectra from X-ray reverberation.
