High speed imaging of Z-pinch gas discharge in extreme ultraviolet and model-based three-dimensional reconstruction of emitting volume.

Review of Scientific Instruments, 2022
We constructed a time-resolved imaging setup with 5 ns time step and 2 ns exposure to record plasma dynamics inside the electrode system of a gas discharge extreme ultraviolet source.

Wide-field ultraviolet imager for astronomical transient studies

Experimental astronomy (Print), 2018
Though the ultraviolet (UV) domain plays a vital role in the studies of astronomical transient events, the UV time-domain sky remains largely unexplored. We have designed a wide-field UV imager that can be flown on a range of available platforms, such as

Optical-Ultraviolet Tidal Disruption Events

Space Science Reviews, 2020
The existence of optical-ultraviolet Tidal Disruption Events (TDEs) could be considered surprising because their electromagnetic output was originally predicted to be dominated by X-ray emission from an accretion disk.

Double-Foci Beamline for Attosecond Transient Reflection Spectroscopy

2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021
Although attosecond transient absorption spectroscopy (ATAS) is a powerful experimental technique, it suffers from important limitations. The high absorption coefficient of solid state samples in the extreme-ultraviolet (XUV) spectral range and the ...

A new framework for soft x-ray transient gratings

Journal of Physics B: Atomic, Molecular and Optical Physics
The capability to use extreme ultraviolet (EUV) light for generating transient gratings (TGs) has enabled the study of thermoelastic and magnetic dynamics at the nanoscale, in thin solid samples and surfaces, without the need of specially modifying them.

Wide-field ultraviolet integral-field spectroscopy with the UMIS testbed experiment

Astronomical Applications
The Ultraviolet Micromirror Imaging Spectrograph (UMIS) is a next-generation instrument designed to build on the successes of traditional long-slit UV spectrographs, such as those used in JUNO-UVS, MAVEN IUVS, and Cassini UVIS, by expanding their one ...

ASKAP J144834−685644: a newly discovered long period radio transient detected from radio to X-rays

Monthly notices of the Royal Astronomical Society
Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarised radio bursts with periods varying from a few minutes to a few hours.

Ultraviolet Luminous Objects in GALEX data: search and possible explanation of their nature

Astronomical and Astrophysical Transactions, Vol. 32, No. 1, 2020
Multi-wavelength characterization of astrophysical objects by means of cross-matching of modern large sky surveys is a powerful tool intensively used for classification, parameterization and studies of various classes of sources.
