asevolution: a relativistic N-body implementation of the (a)symmetron
Øyvind Christiansen, Farbod Hassani, Mona Jalilvand +1
We present asevolution, a cosmological N-body code developed based on gevolution, which consistently solves for the (a)symmetron scalar field and metric potentials within the weak-…
Model-Independent Test for Gravity using Intensity Mapping and Galaxy Clustering
Muntazir M. Abidi, Camille Bonvin, Mona Jalilvand +1
We propose a novel method to measure the statistic from clustering alone. The statistic provides an elegant way of testing the consistency of General Relativity by comp…
An Estimator for the lensing potential from galaxy number counts
Viraj Nistane, Mona Jalilvand, Julien Carron +2
We derive an estimator for the lensing potential from galaxy number counts which contains a linear and a quadratic term. We show that this estimator has a much larger signal-to-noi…
The Hydrogen Intensity and Real-time Analysis eXperiment: 256-Element Array Status and Overview
Devin Crichton, Moumita Aich, Adam Amara +97
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the S…
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…
