Chandra observations of the old pulsar PSR B1451-68
, 2012 We present 35 ks Chandra ACIS observations of the 42 Myr old radio pulsar PSR B1451-68. A point source is detected 0.32" +/- 0.73" from the expected radio pulsar position. It has ~200 counts in the 0.3-8 keV energy range. We identify this point source as

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

Spectral analysis of ultraluminous X-ray pulsars with models of X-ray pulsars
Monthly Notices of the Royal Astronomical SocietyABSTRACT A fraction of the ultraluminous X-ray (ULX) sources are known to be accreting neutron stars as they show coherent X-ray pulsations with pulse periods ranging from ${\sim} 1{\!-\!}30$ s. While initially thought to host intermediate-mass black holes, ULXs have since been recognized as a diverse class of objects, including ULX ...

Elastic Properties of Returned Samples From Asteroid (162173) Ryugu
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract The successful sample return from asteroid (162173) Ryugu by Hayabusa2 has contributed to our understanding of the solar system evolution. Over the course of the initial sample analysis, various measurements were conducted, such as mineralogical observation, chemical analysis, and mechanical property measurement.

, 2012 Accreting X-ray pulsars are among the most luminous objects in the X-ray sky. In highly magnetized neutron stars (B~10^12 G), the flow of matter is dominated by the strong magnetic field. The general properties of accreting X-ray binaries are presented, focusing on the spectral characteristics of the systems.

The emerging population of pulsar wind nebulae in hard X-rays
, 2009 The hard X-ray synchrotron emission from pulsar wind nebulae (PWNe) probes energetic particles, closely related to the pulsar injection power at the present time. INTEGRAL has disclosed the yet poorly known population of hard X-ray pulsar/PWN systems. We
