A low value of in tension with the distance ladder from Megamasers using peculiar velocity reconstruction
Richard Watkins, Hume A. Feldman
Megamaser distances can be measured without using the traditional distance ladder. As such, they provide an independent probe of the local expansion rate, quantified by the Hubble…
Analyzing the Large-Scale Bulk Flow using CosmicFlows4: Increasing Tension with the Standard Cosmological Model
Richard Watkins, Trey Allen, Collin James Bradford +7
We present an estimate of the bulk flow in a volume of radii Mpc using the minimum variance (MV) method with data from the CosmicFlows-4 (CF4) catalog. The addition…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Improved Methods for Estimating Peculiar Velocity Correlation Functions Using Volume Weighting
Yuyu Wang, Sarah Peery, Hume A. Feldman +1
We present an improved method for calculating the parallel and perpendicular velocity correlation functions directly from peculiar velocity surveys using weighted maximum-likelihoo…
Peculiar Velocity Estimation from Kinetic SZ Effect using Deep Neural Networks
Yuyu Wang, Nesar Ramachandra, Edgar M. Salazar-Canizales +3
The Sunyaev-Zel'dolvich (SZ) effect is expected to be instrumental in measuring velocities of distant clusters in near future telescope surveys. We simplify the calculation of pecu…
Easily Interpretable Bulk Flows: Continuing Tension with the Standard Cosmological Model
Sarah Peery, Richard Watkins, Hume A. Feldman
We present an improved Minimal Variance (MV) method for using a radial peculiar velocity sample to estimate the average of the three-dimensional velocity field over a spherical vol…
