<p><strong>Title:&nbsp;</strong>21cm cosmology using neutral hydrogen (HI)&nbsp;intensity&nbsp;mapping
</p>
<p><strong>Abstract:</strong>
</p>
<p>21cm cosmology is a new area of research with a great deal of potential.&nbsp;Intensity&nbsp;mapping is an innovative technique, which uses&nbsp;HI&nbsp;to&nbsp;map&nbsp;the large-scale structure of the Universe in three dimensions. In this talk I will first give a review of the possibilities for precision cosmology with 21cm fluctuations, with special emphasis on the&nbsp;intensity&nbsp;mapping&nbsp;technique.&nbsp;I will then present recent work on forecasts for clustering and lensing measurements using&nbsp;intensity&nbsp;mapping&nbsp;surveys with the Square Kilometre Array (SKA) and its pathfinders (MeerKAT), alone and in combination with optical galaxy surveys like Euclid. Suchmeasurements can be used to constrain&nbsp;HI, galaxy, and cosmological parameters across a wide range of redshift.&nbsp;I will also discuss the possibility to test General Relativity and the standard cosmological model using&nbsp;HI&nbsp;intensity mapping, optical galaxy and CMB lensing surveys.
