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.

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 ...

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars

The Astrophysical Journal Letters
Studying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Theoretical design and analysis of the layered synthetic microstructure optic for the dual path X-ray telescope [PDF]

A ray tracing analysis was performed for several configurations for the inner channel of the dual path X-ray telescope, which is proposed to use the second mirror of the Stanford/MSFC Wolter-Schwarzchild telescope and a normal incident layered synthetic ...
