Systematic effects on lensing reconstruction from a patchwork of CMB polarization maps

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Ryo Nagata, Toshiya Namikawa, , , | Summary: We investigate the tolerance for systematic errors in lensing analysis applied to a patchwork map of Cosmic Microwave Background polarization. We focus on the properties of the individual polarization maps that comprise the patchwork and discuss the associated calibration […]

Constraining Ultralight ALP Dark Matter in Light of Cosmic Birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Dongdong Zhang, Elisa G. M. Ferreira, Ippei Obata, Toshiya Namikawa, | Summary: Cosmic birefringence, the observed rotation of the polarization plane of the cosmic microwave background (CMB), serves as a compelling probe for parity-violating physics beyond the Standard Model. This study explores the potential of ultralight axion-like […]

From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zeyu Gao, Yingjie Peng, Kai Wang, Luis C. Ho, Alvio Renzini | Summary: The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional methods, including both parametric and non-parametric approaches, often fail to […]

Field-level Emulation of Cosmic Structure Formation with Cosmology and Redshift Dependence

Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Francisco Villaescusa-Navarro, Shirley Ho, David N. Spergel | Summary: We present a field-level emulator for large-scale structure, capturing the cosmology dependence and the time evolution of cosmic structure formation. The emulator maps linear displacement fields to their corresponding nonlinear displacements from N-body […]

Evolving Dark Energy or Supernovae Systematics?

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: Recent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with DESI measurements of baryon acoustic […]
