Control variates from Eulerian and Lagrangian perturbation theory: Application to the bispectrum
Nickolas Kokron, Shi-Fan Chen
Control variates have seen recent interest as a powerful technique to reduce the variance of summary statistics measured from costly cosmological -body simulations. Of particula…
The Squeezed Bispectrum from CHIME HI Emission and Planck CMB Lensing: Current Sensitivity and Forecasts
CHIME Collaboration, Arnab Chakraborty, Matt Dobbs +18
Line intensity mapping using atomic hydrogen (HI) has the potential to efficiently map large volumes of the universe if the signal can be successfully separated from overwhelmingly…
Direct correlation of line intensity mapping and CMB lensing from evolution along the lightcone
Delon Shen, Nickolas Kokron, Emmanuel Schaan
Line intensity mapping (LIM) promises to probe previously inaccessible corners of the faint and high-redshift universe. However, confusion with bright foregrounds is a major challe…
Cross-correlation of Luminous Red Galaxies with ML-selected AGN in HSC-SSP III: HOD Parameters for Type I and Type II Quasars
Rodrigo Córdova Rosado, Andy D. Goulding, Jenny E. Greene +4
Understanding the dark matter (DM) halo environment in which galaxies that host active galactic nuclei (AGN) reside is a window into the nature of supermassive black hole (SMBH) ac…
How do uncertainties in galaxy formation physics impact field-level galaxy bias?
Mahlet Shiferaw, Nickolas Kokron, Risa H. Wechsler
Our ability to extract cosmological information from galaxy surveys is limited by uncertainties in the galaxy-dark matter halo relationship for a given galaxy population, which are…
On the contributions of extragalactic CO emission lines to ground-based CMB observations
Nickolas Kokron, José Luis Bernal, Jo Dunkley
We investigate the potential of CO rotational lines at redshifts being an appreciable source of extragalactic foreground anisotropies in the cosmic microwave background…
