Southern Africa is becoming a beacon for astronomy throughout the electromagnetic spectrum: In all wavebands accessible from ground, the largest astronomical facilities are either operational or in the process of being set up in the region, see e.g. [1].

Prof. Petri Vaisanen (South African Astronomical Observatory)29/06/2018, 14:00Oral Presentation
The South African Astronomical Observatory (SAAO) turns 200 years in 2020. It is the premier optical astronomy research facility on the African continent. The Southern African Large Telescope (SALT) is a 10m class telescope, the largest one in the Southern Hemisphere, and the flagship facility at the Sutherland observing site that SAAO operates. I will summarise the current status of SALT...

General relativistic astrophysics and elementary particle and nuclear physics are strongly connected and their results are interdependent. Although the physical systems are quite different, the 4D-simulation of a merger of a binary system of two neutron stars and the properties of the hot and dense matter created in high energy heavy ion collisions, strongly depend on the equation of state of...

Reionization was a very critical process in the Universe in the transition from an opaque to a transparent Universe. However, we do not fully understand how this event happened. Using the kinetic Sunyaev-Zel'dovich Effect (kSZ), we can look critically into the reionization epoch of the Universe. This work predicts how well we can constrain cosmological parameters using forecasted data from the...

The Africa Millimetre Telescope (AMT) will be built on Mount Gamsberg in Namibia, to form part of a world-wide interferometric network of millimetre-wave telescopes to resolve the event horizon of the Galaxy's supermassive blackhole. At a distance of 8kpc and a mass of about 4 million solar masses, the event horizon should subtend an angle of about 10 micro arc seconds from Earth. This is too...

The closest known active galaxy is Centaurus A (Cen A) at a distance of 3.8 Mpc. Due to its proximity, Cen A has been observed over a wide range of energy bands. These extensive observations enabled various astrophysical phenomena associated with active galaxies to be studied in great detail. Cen A has recently been observed by H.E.S.S. and Fermi-LAT in gamma-rays. In describing the spectral...

In this talk, we present preliminary measurements of type Ia supernova spectral features such as equivalent widths and flux ratios and how such measurements are applied to the derivation of dust reddening in galaxies in which type Ia supernovae are discovered and the way they can be used to standardise type Ia supernova light curves in a more accurate manner than the traditional photometric...

I will present a brief overview of optical astronomy in South Africa in the context of the multi-wavelength astronomy strategy of South Africa. I will focus on the role of optical astronomy in support of radio and gamma-ray observations, and highlight the new and unique MeerLICHT optical telescope which will provide a real-time view at optical wavelengths of the MeerKAT radio sky. By...

ANTARES, the largest deep-underwater Cherenkov neutrino telescope operating in the Northern hemisphere, has been taking data since 2007 with the primary objective of searching for high-energy astrophysical neutrinos in the TeV-PeV range. Thanks to its excellent angular resolution, ANTARES has searched for neutrino sources and set important constraints on the origin of the neutrino cosmic flux,...
