Trumpeting the Vuvuzela: The deepest HI observations with MeerKAT
Benne Willem Holwerda, S.-L. Blyth · 2010
The MeerKAT UltraDeep HI Survey aims to observe the 21 cm emission line of neutral hydrogen gas out to a redshift of z=1 and beyond.From both direct detections and stacked signal, we will address the H I mass function, the cosmic neutral gas density of the Universe (Ω HI ) and their evolution over cosmic times, as well as galaxy evolution via e.g., the Tully-Fisher relation, the relation between H I mass and Hubble Type or stellar mass, and the Schmidt-Kennicutt starformation law.We propose to observe two fields, the COSMOS and Chandra Deep Field South (CDF-S) for 1000 hours each, adding an additional 4000 hours to one of these fields in 2015 when the full instantaneous bandwidth of MeerKAT (0.58-2.5 GHz) will be realised.
