AutoCal: A software application for calibrating photometric data

open access: yesSouth African Journal of Science, 2016
We present a software application for the calibration of stellar magnitudes in the absence of standard stars. It uses an existing algorithm to match stars in the target’s field of view to catalogue entries and computes the average offset between the two ...

Direct Reactions with Exotic Nuclei, Nuclear Structure and Astrophysics [PDF]

open access: yes, 2006
Intermediate energy Coulomb excitation and dissociation is a useful tool for nuclear structure and astrophysics studies. Low-lying strength in nuclei far from stability was discovered by this method.

Toward Calibration of the Global Network of Gravitational Wave Detectors with Sub-Percent Absolute and Relative Accuracy

open access: yesGalaxies, 2022
The detection of gravitational-wave signals by the LIGO and Virgo observatories during the past few years has ushered us into the era of gravitational-wave astronomy, shifting our focus from detection to source parameter estimation.

Testing Noncommutativity-Like Model as a Galactic Density Profile

open access: yesGalaxies, 2021
Noncommutative-like model (NC-like) is an interesting alternative inspired by string theory to understand and describe the velocity rotation curves of galaxies without the inclusion of dark matter particles.

Visualization in astrophysics [PDF]

open access: yes, 1989
This paper reports on progress we have made in modelling cosmic X·ray sources on supercomputers. The results we present are meant to serve as an example for the fact that sophisticated visualization techniques play a crucial role in scientific computing.

Towards the first plasma-electron screening experiment

open access: yesFrontiers in Physics, 2023
The enhancement of fusion reaction rates in a thermonuclear plasma by electron screening of the Coulomb barrier is an important plasma-nuclear effect that is present in stellar models but has not been experimentally observed.
