The effect of transport apertures on relay‐imaged, sharp‐edged laser profiles in photoinjectors and the impact on electron beam properties

Journal of Synchrotron Radiation, Volume 31, Issue 4, Page 723-732, July 2024.
Wavefront propagation studies show that apertures in the laser injection path into photoinjector electron guns result in spatial ripples in relay‐imaged cut‐Gaussian profiles. The effect on electron beam properties depends on the extent to which space charge washes out the corresponding ripples in the emitted electron bunch, but could significantly ...

Relationship Between Advanced Footwear Technology Longitudinal Bending Stiffness and Energy Cost of Running

Scandinavian Journal of Medicine &Science in Sports, Volume 34, Issue 6, June 2024.
ABSTRACT Introduction/Purpose Shoe longitudinal bending stiffness (LBS) is often considered to influence running economy (RE) and thus, running performance. However, previous results are mixed and LBS levels have not been studied in advanced footwear technology (AFT).

Hard X-Ray Spectrum of the Vela Pulsar and Its Wind Nebula Constrained by NuSTAR

The Astrophysical Journal
We present the analysis of 200 ks NuSTAR observation of the Vela pulsar and the pulsar wind nebula (PWN). The phase-resolved spectra corresponding to two main peaks in the folded pulse profile differ significantly. The spectrum of Peak 1 is significantly

On the overall properties of young neutron stars: an application to the Crab pulsar

Frontiers in Astronomy and Space Sciences
In this brief report, we present a model that complements the well-established canonical model for the spin evolution of rotation-powered pulsars, which is typically used to estimate ages, spin-down luminosity, and surface magnetic fields of middle-aged ...

Dynamic Covalent Synthesis Applied to Optoelectronic and Energy Materials: Design, Applications and Limitations

European Journal of Organic Chemistry, Volume 27, Issue 20, May 27, 2024.
Dynamic Covalent Chemistry can bring together simple components to create complex self‐assembled materials. This strategy is so far under‐investigated in the field of optoelectronic and energy materials. However, it has the potential to rapidly produce self‐assembled organic semiconductors or stimuli responsive devices.

Exploring Waveform Variations among Neutron Star Ray-tracing Codes for Complex Emission Geometries

The Astrophysical Journal
Pulse profile modeling (PPM), the technique used to infer mass, radius, and geometric parameters for rotation-powered millisecond pulsars using data from the Neutron Star Interior Composition Explorer (NICER), relies on relativistic ray-tracing of ...

Electrodynamics and Radiation from Rotating Neutron Star Magnetospheres

Universe, 2020
Neutron stars are compact objects rotating at high speed, up to a substantial fraction of the speed of light (up to 20% for millisecond pulsars) and possessing ultra-strong electromagnetic fields (close to and sometimes above the quantum critical field ...

Gathering Evidence to Leverage Musculoskeletal Magnetic Stimulation Towards Clinical Applicability

Small Science, Volume 4, Issue 5, May 2024.
Inductive coupling (IC)‐induced magnetic stimulation is here reviewed as a safe and promising non‐invasive therapy to manage musculoskeletal disorders, such as osteoporosis, osteoarthritis, and implant osseointegration. Gathered data, based on the trends, operating parameters and outcomes of 117 IC pre‐clinical and clinical studies, will aid on ...

Detection of Diffuse Radio Emission inside the Supernova Remnant G338.3-0.0 Associated with the γ-Ray Source HESS J1640-465

The Astrophysical Journal
We report the discovery of diffuse radio emission within SNR G338.3−0.0 using new MeerKAT observations at 816 MHz and 1.4 GHz. The radio emission spatially overlaps with the X-ray pulsar wind nebula (PWN) powered by PSR J1640−4631 and the GeV/TeV γ -ray ...

Dense matter with eXTP

, 2018
In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores host an extreme density regime which cannot be replicated in a terrestrial laboratory.
