The POLARBEAR-2 and Simons Array Focal Plane Fabrication Status
B. Westbrook, P. A. R. Ade, M. Aguilar +90
We present on the status of POLARBEAR-2 A (PB2-A) focal plane fabrication. The PB2-A is the first of three telescopes in the Simon Array (SA), which is an array of three cosmic mic…
The Atacama Cosmology Telescope: limits on dark matter-baryon interactions from DR4 power spectra
Zack Li, Rui An, Vera Gluscevic +20
Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling b…
CMB lensing with shear-only reconstruction on the full sky
Frank J. Qu, Anthony Challinor, Blake D. Sherwin
Reconstruction of gravitational lensing effects in the CMB from current and upcoming surveys is still dominated by temperature anisotropies. Extragalactic foregrounds in temperatur…
Probing early structure and model-independent neutrino mass with high-redshift CMB lensing mass maps
Frank J. Qu, Blake D. Sherwin, Omar Darwish +2
CMB lensing maps probe the mass distribution in projection out to high redshifts, but significant sensitivity to low-redshift structure remains. In this paper we discuss a method t…
Restoring cosmological concordance with early dark energy and massive neutrinos?
Alexander Reeves, Laura Herold, Sunny Vagnozzi +2
The early dark energy (EDE) solution to the Hubble tension comes at the cost of an increased clustering amplitude that has been argued to worsen the fit to galaxy clustering data.…
Determining the Hubble Constant without the Sound Horizon: A Constraint on from Galaxy Surveys, CMB Lensing and Supernovae
Oliver H. E. Philcox, Gerrit S. Farren, Blake D. Sherwin +2
Many theoretical resolutions to the so-called "Hubble tension" rely on modifying the sound horizon at recombination, , and thus the acoustic scale used as a standard ruler in…
