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…
Local primordial non-Gaussianity from 'zero-bias' 21cm radiation during reionization
Nickolas Kokron
We revisit the potential of 21cm radiation fluctuations, during the epoch of reionization, in constraining the amplitude of local primordial non-Gaussianity (PNG) $f_{\rm NL}^{\rm…
Cross-correlation of Luminous Red Galaxies with ML-selected AGN in HSC-SSP II: AGN classification and clustering with DESI spectroscopy
Rodrigo Córdova Rosado, Andy D. Goulding, Jenny E. Greene +5
An unresolved question in studies of active galactic nuclei (AGN) is whether their different classes probe different evolutionary stages of black hole--host galaxy interaction. We…
Neural Network Acceleration of Large-scale Structure Theory Calculations
Joseph DeRose, Shi-Fan Chen, Martin White +1
We make use of neural networks to accelerate the calculation of power spectra required for the analysis of galaxy clustering and weak gravitational lensing data. For modern perturb…
