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…
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 (C…
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…
The Atacama Cosmology Telescope DR6 and DESI: Structure formation over cosmic time with a measurement of the cross-correlation of CMB Lensing and Luminous Red Galaxies
Joshua Kim, Noah Sailer, Mathew S. Madhavacheril +70
We present a high-significance cross-correlation of CMB lensing maps from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) with spectroscopically calibrated luminous red…
Cosmological constraints from the cross-correlation of DESI Luminous Red Galaxies with CMB lensing from Planck PR4 and ACT DR6
Noah Sailer, Joshua Kim, Simone Ferraro +63
We infer the growth of large scale structure over the redshift range from the cross-correlation of spectroscopically calibrated Luminous Red Galaxies (LR…
