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

Posted by klaurent MIT

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

Posted by klaurent Peking

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

Posted by klaurent MIT

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

Posted by klaurent Tokyo

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, […]

Single-shot 3D photoacoustic computed tomography with a densely packed array for transcranial functional imaging

Posted by klaurent Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Rui Cao, Yilin Luo, Jinhua Xu, Xiaofei Luo, Ku Geng | Summary: Photoacoustic computed tomography (PACT) is emerging as a new technique for functional brain imaging, primarily due to its capabilities in label-free hemodynamic imaging. Despite its potential, the transcranial application of PACT has encountered hurdles, […]
