In parallel with the multi-messenger revolution, major advances in time-domain astronomy across multiple science disciplines relevant to astrophysics are becoming more urgent to address. Aside from electromagnetic observations of gravitational wave e

In May 2010, an intermediate luminosity optical transient was discovered in the nearby galaxy NGC 300 by a South African amateur astronomer. In the decade since its discovery, multi-wavelength observations of the misnamed “SN 2010da” have continu

Supermassive black holes (SMBH, 10^5-10^10 M_odot) have regularly been found at the center of massive galaxies. However, we still know little about their formation mechanism. Extremely luminous active galactic nuclei (AGN), revealing the presence of

DSc (Space Physics), North-West University, Potchefstroom Campus Space weather (SWx) studies and the development of SWx prediction models have gained significant momentum in the last few years. Large SWx events have the potential to incapacitate tech

Over the past two decades, detailed studies in the nearby Universe have shown that accreting supermassive black holes (SMBHs; or active galactic nuclei; AGN) can have a significant effect on their host galaxies, suppressing star formation and regulat

We present the results of the multi- wavelength study of the two-ribbon solar flare on July 19, 2000 in the active region NOAA 9087. The evo- lution and morphological properties of the flare pro- ductive active region have been analyzed. The active r

During my Ph.D., I carried out a multi-wavelength study of narrow-line Seyfert 1 galaxies (NLS1s), with the aim of better understanding this peculiar class of AGN. I present a new accurately selected catalog of NLS1s in the southern hemisphere from t

We present the results of the analysis of morphology and evolution of the circular solar flare using H-alpha images. H-alpha filtergrams were obtained with the Meudon spectroheliograph. The active region NOAA 9087 had a complex multipolar magnetic fi
