Lyα Intensity Mapping in HETDEX: Galaxy-Lyα Intensity Cross-Power Spectrum
Maja Lujan Niemeyer, Eiichiro Komatsu, José Luis Bernal +18
We present a measurement of the Lyman- (Ly) intensity mapping power spectrum from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We measure the cross-power spe…

Delensing CMB B-modes using galaxy surveys: the effect of galaxy bias and matter clustering non-linearities
Shengzhu Wang, Antón Baleato Lizancos, José Luis Bernal
The B-mode of polarization of the CMB is a uniquely powerful probe of gravitational waves produced in the very early Universe. But searches for primordial B-mode anisotropies must…

Removal of interloper contamination to line-intensity maps using correlations with ancillary tracers of the large-scale structure
José Luis Bernal, Antón Baleato Lizancos
Line-intensity mapping (LIM) offers an approach to obtain three-dimensional maps of the large-scale structure by collecting the aggregate emission from all emitters along the line…
