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…
The LOFAR Two-metre Sky Survey: VII. Third Data Release

Renzo's rule revisited: A statistical study of galaxies' baryon - dark matter coupling
Enoch Ko, Tariq Yasin, Harry Desmond +2
We present a systematic statistical analysis of an informal astrophysical phenomenon known as Renzo's rule (or Sancisi's law), which states that "for any feature in a galaxy's lumi…
MIGHTEE: exploring the relationship between spectral index, redshift and radio luminosity
Siddhant Pinjarkar, Martin J. Hardcastle, Dharam V. Lal +9
It has been known for many years that there is an apparent trend for the spectral index (α) of radio sources to steepen with redshift z, which has led to attempts to select high-re…
