The cosmic web in the Laduma field
… at the Distant Universe with the MeerKAT Array (LADUMA) survey at higher redshifts. LADUMA's ancillary data catalogue provides a limited sample of spectroscopic redshift measurements across LADUMA's target volume. I use the DisPerSE software package to identify large-scale structures. I use the …

The automated detection and multiwavelength properties of LADUMA HI galaxies
… At the Distant Universe with the MeerKAT Array (LADUMA) survey. LADUMA is a deep and narrow HI emission survey underway with the MeerKAT telescope. We perform automated source finding over the low redshift Early Science LADUMA data cube using the SoFiA-2 algorithm. The source finding mask created …

HI Lightcones for LADUMA using Gadget-3 : performance profiling and application of an HPC code
… what it will observe when it conducts the LADUMA ultra-deep HI survey. This lightcone will assist in the planning process of the survey. The deliverables for this project are summarised as follows: * Provide an up-to-date performance evaluation and optimisation report for the cosmological …

The discovery and characterization of astrophysical transients with MeerKAT
… our commensal search for radio transients in the LADUMA field using SARAO Science Data Processor (SDP) UHF-band images, covering∼1 year of observations. Employing the Transient Pipeline (TraP), I identified source candidates within the LADUMA field, and applied additional filtering methods to …

Using HI stacking to study galaxy properties in the nearby universe (Looking for needles in the HI-stack)
… operating and enable deeper, large surveys (e.g. LADUMA) of neutral gas in galaxies. Hi Stacking is an observational technique that will be highly exploited to learn about the Hi content of galaxies that are not directly detected. Stacking involves combining the Hi spectra of all the galaxies in a …

Optimisation of galaxy identification methods on large interferometric surveys
… SKA pathfinders planned large HI surveys such as LADUMA; Fornax HI survey; DINGO; WALLABY; etc. necessitate fully automated three-dimensional (3D) source finding and parametrization tools. A fraction of the percentage difference in the performance of these automated tools corresponds to a …
