A Dark Matter Trigger for Early Dark Energy Coincidence
Meng-Xiang Lin, Evan McDonough, J. Colin Hill +1
Early dark energy (EDE), whose cosmological role is localized in time around the epoch of matter-radiation equality in order to resolve the Hubble tension, introduces a new coincid…
Squeezing out of the matter bispectrum with consistency relations
Samuel Goldstein, Angelo Esposito, Oliver H. E. Philcox +4
We show how consistency relations can be used to robustly extract the amplitude of local primordial non-Gaussianity () from the squeezed limit of the matter bispectrum,…
The SZ flux-mass (-) relation at low halo masses: improvements with symbolic regression and strong constraints on baryonic feedback
Digvijay Wadekar, Leander Thiele, J. Colin Hill +8
Feedback from active galactic nuclei (AGN) and supernovae can affect measurements of integrated SZ flux of halos () from CMB surveys, and cause its relation with the…
The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements
Christina D. Kreisch, Minsu Park, Erminia Calabrese +21
We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works,…
Intra-Cavity Frequency-Doubled VECSEL System for Narrow Linewidth Rydberg EIT Spectroscopy
Joshua C. Hill, William K. Holland, Paul D. Kunz +4
Vertical external-cavity surface-emitting lasers (VECSELs) augmented by intra-cavity nonlinear optical frequency conversion have emerged as an attractive light source of ultraviole…
Snowmass2021 Cosmic Frontier: Cosmic Microwave Background Measurements White Paper
Clarence L. Chang, Kevin M. Huffenberger, Bradford A. Benson +128
This is a solicited whitepaper for the Snowmass 2021 community planning exercise. The paper focuses on measurements and science with the Cosmic Microwave Background (CMB). The CMB…
Constraining the galaxy-halo connection of infrared-selected unWISE galaxies with galaxy clustering and galaxy-CMB lensing power spectra
Aleksandra Kusiak, Boris Bolliet, Alex Krolewski +1
We present the first detailed analysis of the connection between galaxies and their dark matter halos for the unWISE galaxy catalog -- a full-sky, infrared-selected sample built fr…
Snowmass2021: Opportunities from Cross-survey Analyses of Static Probes
Eric J. Baxter, Chihway Chang, Andrew Hearin +37
Cosmological data in the next decade will be characterized by high-precision, multi-wavelength measurements of thousands of square degrees of the same patches of sky. By performing…
What does cosmology tell us about the mass of thermal-relic dark matter?
Rui An, Vera Gluscevic, Erminia Calabrese +1
The presence of light thermally coupled dark matter affects early expansion history and production of light elements during the Big Bang Nucleosynthesis. Specifically, dark matter…
Inverse-Compton Scattering of the Cosmic Infrared Background
Alina Sabyr, J. Colin Hill, Boris Bolliet
The thermal Sunyaev-Zel'dovich (tSZ) effect is the distortion generated in the cosmic microwave background (CMB) spectrum by the inverse-Compton scattering of CMB photons off free,…
Constraints on Pre-Recombination Early Dark Energy from SPT-3G Public Data
Adrien La Posta, Thibaut Louis, Xavier Garrido +1
Early dark energy (EDE) is a proposed solution to the Hubble tension in which a new cosmological field accelerates cosmic expansion prior to recombination and reduces the physical…
Percent-level constraints on baryonic feedback with spectral distortion measurements
Leander Thiele, Digvijay Wadekar, J. Colin Hill +7
High-significance measurements of the monopole thermal Sunyaev-Zel'dovich CMB spectral distortions have the potential to tightly constrain poorly understood baryonic feedback proce…
Augmenting astrophysical scaling relations with machine learning: application to reducing the Sunyaev-Zeldovich flux-mass scatter
Digvijay Wadekar, Leander Thiele, Francisco Villaescusa-Navarro +7
Complex astrophysical systems often exhibit low-scatter relations between observable properties (e.g., luminosity, velocity dispersion, oscillation period). These scaling relations…
