Einstein beams and the diffractive aspect of gravitationally-lensed light
New 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.

Extragalactic eclipsing binaries: astrophysical laboratories [PDF]
New Astronomy Reviews, 2004 Eclipsing binaries (EBs) have long been known for providing accurate stellar fundamental properties, such as masses and radii. These are obtained from the modeling of light and radial velocity curves and, with input data of good quality, uncertainties of a few percent in the components’ physical properties are now routinely achieved.

Laboratory for Underground Nuclear Astrophysics (LUNA)
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1994 A compact high-current 50 kV ion accelerator facility including a windowless gas target system, a beam calorimeter, and detector telescopes in close geometry has been built and tested. The data acquisition and analysis involved a multiparameter system and a Monte Carlo program.

Felsenkeller shallow-underground accelerator laboratory for nuclear astrophysics
EPJ Web of Conferences, 2015 Favored by the low background in underground laboratories, low-background accelerator-based experiments are an important tool to study nuclear reactions involving stable charged particles. This technique has been used for many years with great success at

Formation of dense, electromagnetically accelerated plasma for laboratory astrophysics
EPJ 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,
