Study on the test of transient ultraviolet spectrum for remote extended area sources with spectrometer

Proceedings of SPIE, 2010
Spectral radiation intensity measurement at ultraviolet wavelengths is important for the material composition analysis of transient extended area light sources. Here we developed transient ultraviolet multi-spectral spectrometer which is utilized to measure relative spectral radiation intensity distributions of remote transient as well as steady ...

Ultraviolet observations of the transient X-ray sources A0535 + 26 and A0620-00

Publications of the Astronomical Society of the Pacific, 1983
Observations of A0535+26 (HDE 245770) by the ANS in September 1975 and March 1976 when it was at the X-ray low state are discussed. Also observed were 58 early-type stars lying within 10 deg of HDE 245770; these stars are used to derive a localized extinction curve. On the basis of the depth of the 2200 A interstellar absorption feature observed in the

Ultraviolet, optical, and radio observations of the transient X-ray source GRO J0422+32

AIP Conference Proceedings, 1993
We have monitored the early evolution of the transient X‐ray source GRO J0422+32 from approximately 2 weeks post‐discovery and into its early decline phase at ultraviolet, optical and radio wavelengths. Optical and ultraviolet spectra, obtained with the Perkins 1.8‐m telescope and with IUE respectively, exhibit numerous, but relatively weak, high ...

Pulsed radiography and tomography of transient and low-density objects using laser plasma sources of extreme ultraviolet (EUV)

EUV and X-ray Optics: Synergy between Laboratory and Space VI, 2019
We present a brief review of radiography technique (shadowgraphy) and its extension to tomography. We used both techniques to characterize i.e. multi-jet gas puff target for different gases with a variable number of jets for various applications.

Matrix Isolation Infrared Observation of H_xSi(N₂)_y (x = 0, 1, 2 and y = 1, 2) Transient Species Using a 121-nm Vacuum Ultraviolet Photolysis Source

The Journal of Physical Chemistry A, 2008
Vacuum ultraviolet photolysis (121.6 nm) of silane in a nitrogen matrix at 12 K leads to the observation of several transient species, which have been characterized using Fourier transform infrared spectroscopy. Four transient species containing silicon and nitrogen have been observed (SiN2, Si(N2)2, HSiN2, and H2SiN2), and one transient species ...
