Sample Variance Cancellation for Future Spectroscopic Surveys
James M. Sullivan, Martin White
High-redshift spectroscopic galaxy surveys will be the scientific engines of the next generation of large-scale structure cosmology. The clustering signal of high redshift, star-fo…
Angular BAO Forecasts for the IBIS Medium-Band Survey
Richard M. Feder, Martin White
Ongoing and near-future spectroscopic surveys, such as DESI, DESI-II and Spec-S5, rely on imaging-based selections to construct uniform, three-dimensional tracers of large-scale st…
Simulation budgeting for hybrid effective field theories
Alexa Bartlett, Joseph DeRose, Martin White
In this work, we forecast the number of, and requirements on, N-body simulations needed to train hybrid effective field theory (HEFT) emulators for a range of use cases, using a hy…
Dispuable: the high cost of a low optical depth
Noah Sailer, Gerrit S. Farren, Simone Ferraro +1
Recent baryonic acoustic oscillation (BAO) measurements from the Dark Energy Spectroscopic Instrument (DESI) are mildly discrepant () with the cosmic microwave background (CM…
Evolution of structure growth during dark energy domination: Insights from the cross-correlation of DESI galaxies with CMB lensing and galaxy magnification

We use the angular cross-correlation between a luminous red galaxy (LRG) sample from the Dark Energy Spectroscopic Instrument (DESI) Legacy Survey data release DR9 and the …
BLAST: Beyond Limber Angular power Spectra Toolkit. A fast and efficient algorithm for 3x2 pt analysis
Sofia Chiarenza, Marco Bonici, Will Percival +1
The advent of next-generation photometric and spectroscopic surveys is approaching, bringing more data with tighter error bars. As a result, theoretical models will become more com…
A comparison of Bayesian sampling algorithms for high-dimensional particle physics and cosmology applications
Joshua Albert, Csaba Balazs, Andrew Fowlie +4
For several decades now, Bayesian inference techniques have been applied to theories of particle physics, cosmology and astrophysics to obtain the probability density functions of…
Not all lensing is low: An analysis of DESIDES using the Lagrangian Effective Theory of LSS
S. Chen, J. DeRose, R. Zhou +39
In this work we use Lagrangian perturbation theory to analyze the harmonic space galaxy clustering signal of Bright Galaxy Survey (BGS) and Luminous Red Galaxies (LRGs) targeted by…
Cosmological constraints from the cross-correlation of DESI Luminous Red Galaxies with CMB lensing from Planck PR4 and ACT DR6
