Astronomy and Astrophysics (ASP)

Section Information

Astronomy and Astrophysics focuses on the study of celestial objects, cosmic phenomena, and the physical processes governing the universe. It encompasses observational and theoretical investigations of stars, planets, galaxies, black holes, cosmic radiation, and the large-scale structure of the cosmos.

Modern research in this field includes stellar and planetary science, cosmology, high-energy astrophysics, exoplanet detection, gravitational waves, interstellar medium studies, astrophysical plasma physics, and computational astrophysics. Advances in telescopes, detectors, satellites, spectroscopy, numerical simulations, and data analysis continue to transform understanding of the universe.

This section publishes observational studies, theoretical models, simulations, instrumentation research, surveys, reviews, and analyses of astrophysical systems and cosmic events across all wavelengths and physical scales.
