Zooming-in on the sources of fast radio transients
, 2022 Since the 1960s, Galactic neutron stars have been known to emit short duration radio transients. More recently, a population of higher luminosity short-duration radio transients originating from extragalactic distances were discovered. The nature of these fast radio bursts (FRBs) still remains a mystery, but it is clear that they reflect an extreme ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Evidence for Gravitational Lensing in FRB 20190320B: A Potential Lens Mass of ∼420 Solar Masses
The Astrophysical JournalDue to their millisecond-duration pulses and high flux, fast radio bursts (FRBs) are ideal probes for detecting low-mass gravitational lensing signals, as their distinctive characteristics make them highly sensitive to subtle time delays and lensing ...

Radio sources in next-generation CMB surveys [PDF]
, 2019 CMB surveys provide, for free, blindly selected samples of extragalactic radio sources at much higher frequencies than traditional radio surveys. Next-generation, ground-based CMB experiments with arcmin resolution at mm wavelengths will provide samples ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Prediction of Multiwavelength Afterglows Associated with FRB 20200120E and FRB 20201124A
The Astrophysical JournalFast radio bursts (FRBs) are mysterious radio transients with uncertain origins and environments. Recent studies suggest that some active FRBs may originate from compact objects in binary systems.

Localising fast radio bursts and other transients using interferometric arrays
, 2015 A new population of sources emitting fast and bright transient radio bursts has recently been identified. The observed large dispersion measure values of FRBs suggests an extragalactic origin and an accurate determination of their positions and distances

Advanced Engineering Materials, EarlyView.This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...
