Low‐grade systemic inflammation biomarkers in sedentary young healthy adults are not significantly affected by a 24‐week concurrent training intervention

Annals of the New York Academy of Sciences, Volume 1547, Issue 1, Page 154-169, May 2025.
A 24‐week supervised concurrent training intervention in sedentary young healthy adults showed minimal effects on low‐grade systemic inflammation biomarkers. Vigorous exercise reduced interleukin‐7 but increased C‐reactive protein compared to moderate exercise and control groups.

NuSTAR and XMM-Newton Observations of PSR J1930+1852 and Its Pulsar Wind Nebula

The Astrophysical Journal
Synchrotron X-ray emission from a pulsar wind nebula (PWN) is a sensitive probe of its magnetic field and high-energy particle population. Here we analyze contemporaneous NuSTAR and XMM - Newton observations of the PWN G54.1+0.3, powered by pulsar PSR ...

Detection of X-ray Emission from the Very Old Pulsar J0108-1431

, 2008
PSR J0108-1431 is a nearby, 170 Myr old, very faint radio pulsar near the "pulsar death line" in the P-Pdot diagram. We observed the pulsar field with the Chandra X-ray Observatory and detected a point source (53 counts in a 30 ks exposure, energy flux ...

Modeling X-Ray and Gamma-Ray Emission from Redback Pulsar Binaries

The Astrophysical Journal
We investigated the multiband emission from the pulsar binaries XSS J12270−4859, PSR J2039−5617, and PSR J2339−0533, which exhibit orbital modulation in the X-ray and gamma-ray bands.

INTEGRAL observations of TeV plerions

, 2006
Amongst the sources seen in very high gamma-rays several are associated with Pulsar Wind Nebulae (``TeV plerions''). The study of hard X-ray/soft gamma-ray emission is providing an important insight into the energetic particle population present in these

Constraints on Diffuse X-Ray Emission from the TeV Halo Candidate HESS J1813-126

The Astrophysical Journal
Extended regions of very high-energy γ -ray emission associated with middle-aged pulsars have been found by γ -ray observatories. These regions, called TeV halos or pulsar halos, are thought to be created when energetic electrons from a pulsar or pulsar ...

A Broadband Study of the Emission from the Composite Supernova Remnant MSH 11-62

, 2012
MSH 11-62 (G291.1-0.9) is a composite supernova remnant for which radio and X-ray observations have identified the remnant shell as well as its central pulsar wind nebula.

Magnetic Field Geometry of the Gamma-Ray Binary PSR B1259–63 Revealed via X-Ray Polarization

The Astrophysical Journal Letters
Some X-ray binaries containing an energetic pulsar in orbit around a normal star accelerate particles to high energies in the shock cone formed where the pulsar and stellar winds collide.

X-ray investigation of the diffuse emission around plausible gamma-ray emitting pulsar wind nebulae in Kookaburra region

, 2012
We report on the results from {\it Suzaku} X-ray observations of the radio complex region called Kookaburra, which includes two adjacent TeV $\gamma$-ray sources HESS J1418-609 and HESS J1420-607.

Relativistic Doppler-boosted emission in gamma-ray binaries

, 2010
Gamma-ray binaries could be compact pulsar wind nebulae formed when a young pulsar orbits a massive star. The pulsar wind is contained by the stellar wind of the O or Be companion, creating a relativistic comet-like structure accompanying the pulsar ...
