Hints of spin-orbit resonances in the binary black hole population

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Sylvia Biscoveanu, Maximiliano Isi, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spin measurements from gravitational wave observations can reveal the binary’s evolutionary history. In particular, the spin orientations of the component black holes within the orbital plane, $phi_1$ and $phi_2$, can be […]

Measuring binary black hole orbital-plane spin orientations

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Maximiliano Isi, Sylvia Biscoveanu, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spins are among the key observables for gravitational wave astronomy. Among the spin parameters, their orientations within the orbital plane, $phi_1$, $phi_2$ and $Delta phi=phi_1-phi_2$, are critical for understanding the prevalence […]

The Simplest and Most Predictive Model of Muon $g-2$ and Thermal Dark Matter

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Dan Hooper, Gordan Krnjaic, , | Summary: The long-standing $4.2 , sigma$ muon $g-2$ anomaly may be the result of a new particle species which could also couple to dark matter and mediate its annihilations in the early universe. In models where both muons and […]

Extragalactic magnetism with SOFIA (Legacy Program) — II: A magnetically-driven flow in the starburst ring of NGC 1097

Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Rainer Beck, Susan E. Clark, Annie Hughes, Alejandro S. Borlaff | Summary: Galactic bars are frequent in disk galaxies and they may support the transfer of matter towards the central engine of active nuclei. The barred galaxy NGC 1097 has magnetic forces controlling the […]

Sub-second periodicity in a fast radio burst

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, Bridget C. Andersen, Kevin Bandura, Mohit Bhardwaj, P. J. Boyle | Summary: The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we report the detection […]

XMM-Newton Observes the Intrabinary Shock of PSR J1959+2048

Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Hongjun An, , | Summary: In a multi-orbit (100 ks) $mathrm{it XMM-Newton}$ exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shock (IBS) emission. The IBS light curve peak appears asymmetric, which […]

An Information-state based Approach to the Optimal Output Feedback Control of Nonlinear Systems

Kavli Affiliate: Ran Wang | First 5 Authors: , , , , | Summary: This paper develops a data-based approach to the closed-loop output feedback control of nonlinear dynamical systems with a partial nonlinear observation model. We propose an information state based approach to rigorously transform the partially observed problem into a fully observed problem […]

Long-Range Superconducting Proximity Effect in Nickel Nanowires

Kavli Affiliate: Ke Wang | First 5 Authors: Jue Jiang, Weiwei Zhao, Fei Wang, Renzhong Du, Ludi Miao | Summary: When a ferromagnet is placed in contact with a superconductor, owing to incompatible spin order, the Cooper pairs from the superconductor cannot survive more than one or two nanometers inside the ferromagnet. This is confirmed […]
