Full-sky bispectrum in redshift space for 21cm intensity maps
Ruth Durrer, Mona Jalilvand, Rahul Kothari +2
We compute the tree-level bispectrum of 21cm intensity mapping after reionisation. We work in the directly observable angular and redshift space, focusing on equal-redshift correla…
Non-linear contributions to angular power spectra
Mona Jalilvand, Basundhara Ghosh, Elisabetta Majerotto +3
Future galaxy clustering surveys will probe small scales where non-linearities become important. Since the number of modes accessible on intermediate to small scales is very high,…
A new estimator for gravitational lensing using galaxy and intensity mapping surveys
Mona Jalilvand, Elisabetta Majerotto, Camille Bonvin +4
We introduce the Galaxy Intensity Mapping cross-COrrelation estimator (GIMCO), which is a new tomographic estimator for the gravitational lensing potential, based on a combination…
Intensity mapping of the 21cm emission: lensing
Mona Jalilvand, Elisabetta Majerotto, Ruth Durrer +1
In this paper, we study lensing of 21cm intensity mapping (IM). Like in the cosmic microwave background (CMB), there is no first order lensing in intensity mapping. The first effec…
