Improving constraints on primordial non-Gaussianity from Quaia with a new cosmological observable: angular redshift fluctuations
José Ramón Bermejo-Climent, Carlos Hernández-Monteagudo, Alba Crespo-Pérez +4
Angular redshift fluctuations (ARF) are a new cosmological observable, recently proposed in the literature. It measures the 2D angular deviations of the average redshift of a given…
Validation of the Hybrid Bias Expansion model for the galaxy bispectrum
Marcos Pellejero Ibáñez, Raul E. Angulo, Laila Linke +8
The Hybrid Bias Expansion model (also known as Hybrid Effective Field Theory, HEFT) provides a promising way to extend the range of validity of perturbative large-scale structure m…
Constraints on primordial non-Gaussianity from Quaia
Giulio Fabbian, David Alonso, Kate Storey-Fisher +1
We analyse the large-scale angular clustering of quasars in the \gaia-\unwise quasar catalog, \quaia, and their cross-correlation with maps of the lensing convergence of the Cosmic…
Fast and accurate Gaia-unWISE quasar mock catalogs from LPT and Eulerian bias
Francesco Sinigaglia, Francisco-Shu Kitaura, Mahlet Shiferaw +3
We present full-sky quasar spectrophotometric mock catalogs with smooth redshift evolution from to , tailored to analyze the Gaia-unWISE Quasar Catalog (Quaia)…
Joint analysis of small-scale galaxy clustering and galaxy--galaxy lensing from BOSS galaxies
Wenhao Gao, Zhenjie Liu, Zhongxu Zhai +8
We present a joint analysis of galaxy clustering and galaxy--galaxy lensing measurements from BOSS galaxies using a simulation-based emulation method combined with a halo occupatio…
Quasar clustering and duty cycle measurements at with the Gaia-unWISE Catalog
Mariona Giner Mascarell, Anna-Christina Eilers, Kate Storey-Fisher
We measure the two-point correlation function of a uniformly selected, all-sky sample of 1.3 million quasars with magnitudes from the Gaia--unWISE Quasar Catalog…
