X-Ray Polarimetry as a Tool to Constrain Orbital Parameters in X-Ray Binaries

The Astrophysical Journal
X-ray binary systems consist of a companion star and a compact object in close orbit. Thanks to their copious X-ray emission, these objects have been studied in detail using X-ray spectroscopy and timing.

Discovery of Twin kHz QPOs in the Peculiar X-Ray Binary Circinus X-1 [PDF]

, 2006
We report the discovery with the RXTE PCA of twin kHz QPOs in the peculiar X-ray binary Circinus X-1. Eleven cases of simultaneous double QPOs occurred, with significances of up to 6.3 and 5.5 σ and centroid frequencies ranging between approximately 56 ...

X-ray detection of the substellar twin 2MASS J11011926-7732383 AB

, 2007
2MASS J11011926-7732383 AB (hereafter 2M1101AB), located in the Cha I star forming region, is a rare wide-separation brown dwarf binary. XMM-Newton and Chandra observations of 2M1101AB have allowed us to examine the influence of physical parameters (mass,

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection

Advanced Functional Materials, EarlyView.
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.

NICER, NuSTAR, and Insight-HXMT Views to the Newly Discovered Black Hole X-Ray Binary Swift J1727.8-1613

The Astrophysical Journal Letters
Swift J1727.8–1613 is a black hole X-ray binary newly discovered in 2023. We perform spectral analysis with simultaneous Insight-HXMT, NICER, and NuSTAR observations when the source was approaching the hard intermediate state.

Side‐Chains Engineered Self‐Assembly of Ortho‐Benzodipyrrole‐Based Acceptors: Comprehensive Exploration of Structure‐Interface‐Photovoltaics Correlations

Advanced Functional Materials, EarlyView.
The side‐chain configuration in the bay region of C‐shaped ortho‐benzodipyrrole‐based non‐fullerene acceptors plays a crucial role in their self‐assembly, single‐crystal structures, and optoelectronic properties. The closely correlated molecular structure and performance underscore the importance of minimizing A–A self‐aggregation and enhancing D–A ...

Chandra Observations of WR147 Reveal a Double X-ray Source

, 2009
We report the first results from deep X-ray observations of the Wolf-Rayet binary system WR147 with the Chandra HETG. Analysis of the zeroth order data reveals that WR147 is a double X-ray source.
