We present a study of the [O iii ] λ 5007 line profile in a subsample of eight active galactic nuclei (AGNs) and six non-AGNs in the optically selected green valley at z < 0.5 using long-slit spectroscopic observations obtained with the 11 m Souther

The cosmic evolution of galaxies' neutral atomic gas content is a major science driver for the Square Kilometre Array (SKA), as well as for its South African (MeerKAT) and Australian (ASKAP) precursors. Among the HI large survey programs (LSPs) plann

Magnetic fields are present throughout the Universe and many astrophysical processes are influenced by their presence. One of the largely unknown aspects of cosmic magnetism is that of the cosmic web and how magnetic fields behave in large scale stru
