Simultaneous X-Ray and Optical Polarization Observations of the Blazar Mrk 421
We present near-simultaneous X-ray and optical polarization measurements in the high synchrotron peaked (HSP) blazar Mrk 421. The X-ray polarimetric observations were carried out using Imaging X-ray Polarimetry Explorer (IXPE) on 2023 December 6.

2FHL J1745.1–3035: A Newly Discovered, Powerful Pulsar Wind Nebula Candidate
We present a multi-epoch, multi-observatory X-ray analysis for 2FHL J1745.1–3035, a newly discovered very high-energy Galactic source detected by the Fermi Large Area Telescope (LAT) located in close proximity to the Galactic Center ( l = 358.°5319; b = −

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Abstract Background Linear accelerators used for cancer treatments, in general, have one flattening filter (FF) for each x‐ray energy. In a newly developed 6 MV low energy linac model, beam optimization at higher dose rates is achieved by two FFs. Purpose To achieve optimization in higher dose rates for smaller fields with FF, one small flattening ...

An electrochemical α‐C─H functionalization of nitramines enables the synthesis of molecules containing bifunctional energetic heterocycles with promising properties. A telescoped, HNO3‐free sequence involving nitration and azolation steps offers a safer, modular, and scalable platform for the synthesis of energetic compounds.

X-Ray Polarization Study of the Neutron Star Low-mass X-Ray Binary GX 349+2
We report the first X-ray polarimetric results of the neutron star (NS) low-mass X-ray binary Z-source GX 349+2 using the Imaging X-ray Polarimetry Explorer (IXPE). We discovered that the X-ray source was polarized at a polarization degree of PD = 1.1% ±

Phase-dependent X-ray observations of the beta Lyrae system: No eclipse in the soft band
We report on observations of the eclipsing and interacting binary beta Lyrae from the Suzaku X-ray telescope. This system involves an early B star embedded in an optically and geometrically thick disk that is siphoning atmospheric gases from a less ...
