The Galactic Center seen with MeerKAT

During its inauguration, the MeerKAT released, to date, the most detailed image of the centre of the Galaxy at L-band (1.28 GHz). Since then, the data have been exploited for various scientific research. One such exploitation was to produce a high resolution mosaic of the Galactic centre. From this mosaic came a catalogue of newly discovered unresolved point sources. Over 1500 sources were identified, of which 20 are steep spectrum point sources (with spectral index < -1.8). The work was motivated by the search for radio pulsar candidates in the continuum domain which, when visible, will be observed as point sources, with an expected steep spectra. The expectation comes from the observed average spectral behaviour of the known radio pulsars. Additionally, radio pulsars are known to have highly linear polarised emission, with some exhibiting circular polarisation. As a follow up study, the newly commissioned S-Band receivers will be used to survey Galactic Centre region at 2.4 GHz and 3.1 GHz, with the intent for polarimetric studies of the Radio Arc bubble, Sgr A and B regions, as well as the newly catalogued point sources. At S-Band, the continuum data will be recorded, while simultaneously placing tied-array beams onto the catalogued point sources to search for any periodicity in the time-domain. I will present the work that went into producing the Galactic centre image and the catalogue, as well as present the preliminary results from the S-Band commissioning data.
