Optical Counterparts of MeerKLASS L-band and UHF-band surveys

M. Klein, S. Mangla, J. Mohr +7

Context: Wide-area radio continuum surveys require reliable optical and infrared counterpart identification, but high optical source densities and extended or multi-component radio…

Fast Simultaneous Surveys with On-the-Fly Mapping

Suman Chatterjee, Sarvesh Mangla, Sourabh Paul +10

The SKAO is a next-generation radio telescope that will transform our understanding of the formation and evolution of radio galaxies, quasars, transients, and other cosmic sources.…

Interferometric HI Intensity Mapping of the Late Time Universe with SKA-Mid

Aishrila Mazumder, Zhaoting Chen, Junaid Townsend +6

We discuss the progress towards using the SKA-Mid for interferometric neutral hydrogen (HI) intensity mapping surveys. By mapping the distribution of cosmic HI distribution through…

Tracing Large-scale Structure with the MeerKLASS On-the-Fly Survey: Angular Clustering of Radio Sources at 816 MHz

Sourabh Paul, Suman Chatterjee, Keith Grainge +8

We present the first measurement of the angular two-point correlation function \(w(θ)\) of radio sources from the MeerKAT Large Area Synoptic Survey (MeerKLASS) UHF on-the-fly (OTF…

Measurements of the HI intensity mapping power spectrum at low redshifts with MIGHTEE data: comparison with detected HI galaxies

Junaid Townsend, Mario G. Santos, Suman Chatterjee +6

Line intensity mapping provides a statistical approach to tracing the large-scale distribution of matter in the Universe. We apply the HI intensity mapping technique to interferome…

Strong nebular HeII emission induced by He ionizing photons escaping through the clumpy winds of massive stars

Arpita Roy, Mark R. Krumholz, Stefania Salvadori +8

The origin of nebular HeII-emission in both local and high-redshift galaxies remains an unsolved problem. Various theories have been proposed to explain it, including HeII-ionizati…
