Upgraded waveform model of eccentric binary black hole based on effective-one-body-numerical-relativity for spin-aligned binary black holes

Kavli Affiliate: Lijing Shao | First 5 Authors: Xiaolin Liu, Zhoujian Cao, Lijing Shao, , | Summary: Effective one body numerical relativity waveform models for spin aligned binary black holes (SEOBNR) are based on the effective one body theoretical framework and numerical relativity simulation results. SEOBNR models have evolved through version 1 to version 4. […]

An observational upper limit on the rate of gamma-ray bursts with neutron star-black hole merger progenitors

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Eric Burns, Philippe Landry, Salvatore Vitale, | Summary: Compact-object binary mergers consisting of one neutron star and one black hole (NSBHs) have long been considered promising progenitors for gamma-ray bursts, whose central engine remains poorly understood. Using gravitational-wave constraints on the population-level NSBH mass and […]

Optical Identification of the Shortest-Period Spider Pulsar System M71E

Kavli Affiliate: Subo Dong | First 5 Authors: Zhuokai Liu, Subo Dong, , , | Summary: M71E is a spider pulsar (i.e., a millisecond pulsar with a tight binary companion) with the shortest known orbital period of P=53.3 min discovered by Pan et al. (2023). Their favored evolutionary model suggests that it bridges between two […]

A Transiting Super-Earth in the Radius Valley and An Outer Planet Candidate Around HD 307842

Kavli Affiliate: Avi Shporer | First 5 Authors: Xinyan Hua, Sharon Xuesong Wang, Johanna K. Teske, Tianjun Gan, Avi Shporer | Summary: We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial velocity (RV) measurements constrain the […]

Hill-top inflation from Dai-Freed anomaly in the standard model — A solution to the iso-curvature problem of the axion dark matter

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Tsutomu T. Yanagida, , , | Summary: The discrete symmetry $Z_4$ in the standard model (SM) with three right-handed neutrinos is free from the Dai-Freed anomaly. Motivated by this $Z_4$ symmetry, we constructed a topological inflation model consistent with all known constraints and observations. However, […]
