An International Journal of Astronomy, Astrophysics and Space Science
Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered.
The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing.
Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
Commonly used title abbreviations: Astrophys Space Sci, Ap&SS
We are pleased to present the Topical Collection “Unexplained Spectral Phenomena in the ISM”, with Guest Editor Prof. Sun Kwok. It is focused on the investigation of spectral phenomena, that even though are pervasively observed in a range of astrophysical environments, remained unidentified after decades of observations. The understanding of diffuse interstellar bands (DIBs) and other spectral features remain some of the key challenges to explain the signature of organic materials in the interstellar medium.
The Editors-in-Chief welcome original contributions to Astrophysics and Space Science covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology.
