On Detecting Nearby Nano-Hertz Gravitational Wave Sources via Pulsar Timing Arrays

Kavli Affiliate: Qingjuan Yu | First 5 Authors: Xiao Guo, Youjun Lu, Qingjuan Yu, , | Summary: Massive binary black holes (MBBHs) in nearby galactic centers, if any, may be nano-Hertz gravitational wave (GW) sources for pulsar timing arrays (PTAs) to detect. Normally the objective GWs for PTA experiments are approximated as plane waves because […]

Measurement of the branching fractions and $CP$ asymmetries of $B^+ rightarrow π^+ π^0$ and $B^+ rightarrow K^+ π^0$ decays in 2019-2021 Belle II data

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We determine the branching fractions ${mathcal{B}}$ and $CP$ asymmetries ${mathcal{A}_{{it CP}}}$ of the decays $B^+ rightarrow pi^+ pi^0$ and $B^+ rightarrow K^+ pi^0$. The results are based on a data set containing 198 million […]

Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality

Kavli Affiliate: Misao Sasaki | First 5 Authors: Marcos M. Flores, Alexander Kusenko, Misao Sasaki, , | Summary: The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in […]

The MegaMapper: A Stage-5 Spectroscopic Instrument Concept for the Study of Inflation and Dark Energy

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: David J. Schlegel, Juna A. Kollmeier, Greg Aldering, Stephen Bailey, Charles Baltay | Summary: In this white paper, we present the MegaMapper concept. The MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts at $2<z<5$. In order to achieve […]
