    • Planck 2018 results VIII. Gravitational lensing 

      Ballardini, M.; Aghanim, N.; Akram, Y. (EDP Sciences, 2020)
      We present measurements of the cosmic microwave background (CMB) lensing potential using the final Planck 2018 temperature and polarization data. Using polarization maps filtered to account for the noise anisotropy, we ...

    • Prospects for cosmic magnification measurements using H I intensity mapping 

      Witzemann, Amadeus; Pourtsidou, Alkistis; Santos, Mario G. (Oxford University Press, 2020)
      We investigate the prospects of measuring the cosmic magnification effect by cross-correlating neutral hydrogen intensity mapping (H I IM) maps with background optical galaxies. We forecast the signal-to-noise ratio for ...
