Identification of the Optical Counterpart of the Fast X-Ray Transient EP240414a

The Astrophysical Journal Letters
Fast X-ray transients (FXTs) are extragalactic bursts of X-rays first identified in archival X-ray data and are now routinely discovered in real time by the Einstein Probe, which is continuously surveying the night sky in the soft (0.5–4 keV) X-ray ...

Search for neutrinos from transient sources with the ANTARES telescope and optical follow-up observations

, 2009
The ANTARES telescope has the opportunity to detect transient neutrino sources, such as gamma-ray bursts, core-collapse supernovae, flares of active nuclei...

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Could a Kilonova Kill: A Threat Assessment

The Astrophysical Journal
Binary neutron star mergers produce high-energy emissions from several physically different sources, including a gamma-ray burst (GRB) and its afterglow, a kilonova (KN), and, at late times, a remnant many parsecs in size.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Synchrotron Break Frequencies of Mildly to Highly Relativistic Outflows Observed Off-axis

The Astrophysical Journal
We consider the synchrotron spectrum produced by mildly to highly relativistic collisionless shocks. Simple analytic formulae are derived for the break frequencies (peak frequency, self-absorption frequency, synchrotron, and inverse Compton cooling ...

Extragalactic and galactic sources: New evidence, new challenges, new opportunities

EPJ Web of Conferences, 2013
Recent data bring in sharper focus the issue of relative contributions of galactic and extragalactic sources of ultrahigh-energy cosmic rays. On the one hand, there is some new evidence, from gamma-ray observations of blazars, that cosmic rays are ...
