Formation of dense, electromagnetically accelerated plasma for laboratory astrophysics [PDF]

open access: diamondEPJ Web of Conferences, 2013
We proposed tapered pinch discharge as a measure to conduct laboratory astrophysics experiments. Basic behaviors of the plasma have been characterized using a prototype device. Results show that the plasma flux and velocity depend on initial gas density,

Nuclear astrophysics in the laboratory and in the universe [PDF]

open access: goldAIP Advances, 2014
Nuclear processes drive stellar evolution and so nuclear physics, stellar models and observations together allow us to describe the inner workings of stars and their life stories.

ISO and Laboratory Astrophysics [PDF]

open access: bronzeSymposium - International Astronomical Union, 1992
ISO, the Infrared Space Observatory is capable of measuring spectra across most of the mid-infrared, the region from 4000 to 500 cm−1 (2.5-20 μm). Of these 3500 cm−1, about 670 have been inaccessible to astronomers due to strong atmospheric absorptions and about 750 cm−1 require an airborne platform, making access limited. ISO will provide high quality

Underground nuclear astrophysics: Status and recent results from Felsenkeller laboratory [PDF]

open access: diamondEPJ Web of Conferences
For almost three decades it has been known that the study of astro-physically important nuclear reactions between stable nuclei requires the use of low-background, underground accelerator laboratories.

Measurement and Modeling of Electron Temperature in Laboratory Photoionized Plasmas Relevant to Astrophysics

open access: goldThe Astrophysical Journal
The electron temperature of photoionized plasmas characterizes the thermalization of photoelectrons, impacts the charge-state distribution, emissivity, and opacity through atomic recombination processes, and is needed to perform detailed comparisons with

Galactic Neighborhood and Laboratory Astrophysics [PDF]

open access: green, 2011
The galactic neighborhood, extending from the Milky Way to redshifts of about 0.1, is our unique local laboratory for detailed study of galaxies and their interplay with the environment. Such study provides a foundation of knowledge for interpreting observations of more distant galaxies and their environment.

Precision laboratory UV and IR wavelengths for cosmological and astrophysical applications [PDF]

open access: yes, 2007
The quality of astronomical spectra is now so high that the accuracy of the laboratory data is getting more and more important for the analysis and interpretation.

Einstein beams and the diffractive aspect of gravitationally-lensed light

open access: yesNew Journal of Physics, 2023
The study of light lensed by cosmic matter has yielded much information about astrophysical questions. Observations are explained using geometrical optics following a ray-based description of light.
