A low-cost X-ray-transparent experimental cell for synchrotron-based X-ray microtomography studies under geological reservoir conditions [PDF]
, 2014 A new modular X-ray-transparent experimental cell enables tomographic investigations of fluid rock interaction under natural reservoir conditions (confining pressure up to 20 MPa, pore fluid pressure up to 15 MPa, temperature ranging from 296 to 473 K ...

The Counterjet Dominates the Production of PeV Photons from Cyg X-3
The Astrophysical Journal LettersWe study the physical mechanisms underlying the production of orbitally modulated PeV photons from Cyg X-3, recently discovered by the LHAASO collaboration. Our key findings are as follows.

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Hard X-Ray Sources in Fermi UFOs
The Astrophysical JournalIdentification and/or association of unidentified γ -ray sources with lower-energy counterparts represents a key challenge in modern astronomy, due to the relatively large positional uncertainty provided by γ -ray detectors.

Nature Communications, 2020 The authors here report a binder-free electrode based on tin nanoarrays deposited on copper substrate. It is found that the locally formed electrochemically inactive tin-copper alloys work as a glue that bridges tin and copper to survive harsh cycling ...

DISCRETE X-RAY SOURCES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2020 Current studies of extragalactic X-ray sources using data from orbital observatory XMM- Newton are at the front line of X-ray astronomy. Resolution capacity of the observatory instruments enable to detect separate X-ray sources in the close galaxies.

Synchrotron Cutoff in Ultraluminous X-Ray Sources
The Astrophysical Journal, 2023 The origin of spectral curvature at energies E ≃ 10 keV in ultraluminous X-ray sources (ULXs) is not well understood. In this paper, we propose a novel mechanism based on synchrotron radiation to explain this cutoff.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens
FEBS Open Bio, EarlyView.Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Two Models for the Orbital Modulation of Gamma Rays in Cyg X-3
The Astrophysical JournalWe model the currently available γ -ray data on Cyg X-3 from the Fermi Large Area Telescope. Thanks to Cyg X-3’s very strong γ -ray activity during 2018–2021, the data quality has significantly improved.
