A rising tide: Intrinsic alignments since the turn of the millennium
Nora Elisa Chisari
The alignments of galaxies across the large-scale structure of the Universe are known to be a source of contamination for gravitational lensing, but they can also probe cosmology a…
Intrinsic alignment of disks and ellipticals across hydrodynamical simulations
M. L. van Heukelum, N. E. Chisari
The correlations between the positions and shapes of galaxies, i.e. intrinsic alignments, have been measured in many observational studies and hydrodynamical simulations. The posit…
Intrinsic alignments of galaxies in multiple projections
Marloes van Heukelum, Dennis Neumann, Marta Garcia Escobar +2
Intrinsic alignments of galaxies are measured and modelled to gain cosmological information, to further understand the interactions between galaxies and to mitigate their effects o…
Rapid cosmological inference with the two-loop matter power spectrum
Thomas Bakx, Henrique Rubira, Nora Elisa Chisari +1
We compute the two-loop effective field theory (EFT) power spectrum of dark matter density fluctuations in CDM using the recently proposed COBRA method (Bakx. et al, 2025). With…
The Bispectrum of Intrinsic Alignments: II. Precision Comparison Against Dark Matter Simulations
Thomas Bakx, Toshiki Kurita, Alexander Eggemeier +2
We measure three-dimensional bispectra of halo intrinsic alignments (IA) and dark matter overdensities in real space from N-body simulations for halos of mass $10^{12}-10^{12.5} M_…
Imaging systematics induced by galaxy sub-sample fluctuation: new systematics at second order
Hui Kong, Nora Elisa Chisari, Boris Leistedt +4
Imaging systematics refers to the inhomogeneous distribution of a galaxy sample caused by varying observing conditions and astrophysical foregrounds. Current mitigation methods cor…
