Phase-resolved Spectroscopy of Low-frequency Quasiperiodic Oscillations from the Newly Discovered Black Hole X-Ray Binary Swift J1727.8-1613

The Astrophysical Journal
Low-frequency quasiperiodic oscillations (LFQPOs) are commonly observed in X-ray light curves of black hole X-ray binaries (BHXRBs); however, their origin remains a topic of debate.

Discovery of a New Flaring Class in GRS 1915+105 Using AstroSat

The Astrophysical Journal
The highly variable black hole X-ray binary GRS 1915+105 has shown many flaring classes when the source oscillates between the high soft state (HS) and the hard intermediate state with a transition time of less than 10 s. The X-ray flux is anticorrelated

XMM-Newton Perspective of the Unique Magnetic Binary-ϵ Lupi

The Astrophysical Journal
The ϵ Lupi A (HD 136504) system stands out among magnetic massive binaries as the only short-period binary system in which both components have detectable magnetic fields.

Discovery of a Pair of Galaxies with Both Hosting X-Ray Binary Candidates at z = 2.544

The Astrophysical Journal Letters
Among high-redshift galaxies, aside from active galactic nuclei (AGNs), X-ray binaries (XRBs) can be significant sources of X-ray emission. XRBs play a crucial role in galaxy evolution, reflecting the stellar populations of galaxies and regulating star ...

Expansion and Spectral Softening of the Dust-scattering Rings of GRB 221009A

The Astrophysical Journal
An expanding X-ray halo or rings appear when short pulses of X-ray radiation from a background source are scattered by clouds of dust in the Milky Way. We study the X-ray rings of the brightest gamma-ray burst (GRB) 221009A, detected by the Swift X-Ray ...
