Stress-Testing Small-Scale Cosmological Inference With Empirical Galaxy--Halo Connection Models

Hanyue Wang, Kate Storey-Fisher, Philip Mansfield +4

Small-scale galaxy clustering contains substantial cosmological information, but extracting it reliably requires robust modeling of the galaxy--halo connection. In this work, we co…

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…

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…

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…

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…

Measurement of the power spectrum turnover scale from the cross-correlation between CMB lensing and Quaia

David Alonso, Oleksandr Hetmantsev, Giulio Fabbian +2

We use the projected clustering of quasars in the Gaia-unWISE quasar catalog, Quaia, and its cross-correlation with CMB lensing data from Planck, to measure the large-scale turnove…

Growth history and quasar bias evolution at z < 3 from Quaia

G. Piccirilli, G. Fabbian, D. Alonso +4

We make use of the Gaia-Unwise quasar catalogue, Quaia, to constrain the growth history out to high redshifts from the clustering of quasars and their cross-correlation with maps o…

Constraining cosmology with the Gaia-unWISE Quasar Catalog and CMB lensing: structure growth

David Alonso, Giulio Fabbian, Kate Storey-Fisher +4

We study the angular clustering of Quaia, a Gaia- and unWISE-based catalog of over a million quasars with an exceptionally well-defined selection function. With it, we derive cosmo…

Can we constrain structure growth from galaxy proper motions?

Iain Duncan, David Alonso, Anže Slosar +1

Galaxy peculiar velocities can be used to trace the growth of structure on cosmological scales. In the radial direction, peculiar velocities cause redshift space distortions, an es…

Aemulus : Precise Predictions for Matter and Biased Tracer Power Spectra in the Presence of Neutrinos

Joseph DeRose, Nickolas Kokron, Arka Banerjee +6

We present the Aemulus simulations: a suite of 150 -body simulations with a mass resolution of $3.51\times 10^{10} \frac{Ω_{cb}}{0.3} ~ h^{-1} M_{\o…

The Aemulus Project VI: Emulation of beyond-standard galaxy clustering statistics to improve cosmological constraints

Kate Storey-Fisher, Jeremy Tinker, Zhongxu Zhai +3

There is untapped cosmological information in galaxy redshift surveys in the non-linear regime. In this work, we use the AEMULUS suite of cosmological -body simulations to const…

The Aemulus Project V: Cosmological constraint from small-scale clustering of BOSS galaxies

Zhongxu Zhai, Jeremy L. Tinker, Arka Banerjee +6

We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics. We focus on the monopole and quadrupole of the redshift-space correla…

Two-point statistics without bins: A continuous-function generalization of the correlation function estimator for large-scale structure

Kate Storey-Fisher, David W. Hogg

The two-point correlation function (2pcf) is the key statistic in structure formation; it measures the clustering of galaxies or other density field tracers. Estimators of the 2pcf…
