We are leading the production of MeerKLASS on-the-fly interferometric imaging data and catalogs for the 10,000 deg2 MeerKLASS UHF survey. My group has focused on the production of continuum imaging and catalogs in UHF (and also L-band over a smaller test field). We are pursuing scientific analyses of multi-wavelength source catalogs, where each radio source is associated with an optical/NIR...

133. Sarah Libanore - "A Tale of Many Lines: Mapping the Cosmos through Line Intensity Mapping"

Line intensity mapping (LIM) is emerging as a powerful observational technique to study the large-scale structure across an unprecedented range of cosmic history. By measuring the integrated emission from entire galaxy populations rather than resolving individual sources, LIM complements traditional galaxy surveys and provides a unique view of the Cosmic Web from the nearby Universe to Cosmic...

112. Oliver Basquette - "The cosmological role of Population II and III X-ray binaries"

29.09.26, 16:20

X-ray binaries (XRBs) are cosmologically significant sources of heating and pre-ionisation in the early Universe, dominating the high-redshift X-ray background throughout Cosmic Dawn and the Epoch of Reionisation (EoR). Population III XRBs are a largely homogeneous population that dominate heating in minihaloes, while Population II X-ray binaries are a highly heterogeneous population, with a...

111. Timo Kist - "Learning CMB-independent reionisation constraints from high-redshift quasars"

01.10.26, 11:40

Understanding the Epoch of Reionisation remains one of the pivotal tasks of modern cosmology, embodied by one of the six base parameters of the Lambda-CDM model: the reionisation optical depth, whose Planck legacy constraint has recently been challenged in order to resolve tensions of the DESI BAO measurements with the base Lambda-CDM model. Meanwhile, next-generation telescopes such as EUCLID...

The epoch of reionisation (EoR) is one of the major phase transitions in the universe’s history as the first UV sources – expected to be hosted by dark matter halos which are end points of structure formation – ionise the neutral hydrogen left after recombination. Theoretically, we expect bubbles of ionised hydrogen centred at UV emitting galaxies to grow and intersect, eventually reionising...

The Lyman-alpha forest is a powerful cosmological probe of matter density fluctuations in the weakly non-linear regime through the high redshift and underdense intergalactic medium (IGM). On small scales, the Lyman-alpha 1D flux power spectrum is uniquely sensitive to both the properties of dark matter and the complex gas dynamics driven by IGM photoheating during reionization, offering...
