Single-photon decays in systems with at least one heavy quark

Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: Hadrons containing at least one heavy quark (charm or bottom) frequently have small enough natural widths that decay modes involving a single photon have detectable branching fractions. Photons of typical energy greater than 100 MeV have been […]

The Io, Europa and Ganymede auroral footprints at Jupiter in the ultraviolet: positions and equatorial lead angles

Kavli Affiliate: George Clark | First 5 Authors: Vincent Hue, Randy Gladstone, Corentin K. Louis, Thomas K. Greathouse, Bertrand Bonfond | Summary: Jupiter’s satellite auroral footprints are a consequence of the interaction between the Jovian magnetic field with co-rotating iogenic plasma and the Galilean moons. The disturbances created near the moons propagate as Alfv’en waves […]

Causal State Estimation and the Heisenberg Uncertainty Principle

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Junxin Chen, Benjamin B. Lane, Su Direkci, Dhruva Ganapathy, Xinghui Yin | Summary: The observables of a noisy quantum system can be estimated by appropriately filtering the records of their continuous measurement. Such filtering is relevant for state estimation and measurement-based quantum feedback control. It is therefore […]

Constrain the Dark Matter Distribution of Ultra-diffuse Galaxies with Globular-Cluster Mass Segregation: A Case Study with NGC5846-UDG1

Jinning Liang, Fangzhou Jiang, Shany Danieli, Andrew Benson, Phil Hopkins | Summary: [[{“value”:”The properties of globular clusters (GCs) contain valuable information of their host galaxies and dark-matter halos. In the remarkable example of ultra-diffuse galaxy, NGC5846-UDG1, the GC population exhibits strong radial mass segregation, indicative of dynamical-friction-driven orbital decay, which opens the possibility of using […]

Constraints on the Local Cosmic Void from the Pantheon Supernovae Data

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Kun-Peng Chen, Morgan Le Delliou, , | Summary: In principle, the local cosmic void can be simply modeled by the spherically symmetric Lemaitre-Tolman-Bondi (LTB) metric. In practice, the real local cosmic void is probably not spherically symmetric. In this paper, to reconstruct a more realistic […]

Time-Interleaved C-band Co-Propagation of Quantum and Classical Channels

Kavli Affiliate: Jing Wang | First 5 Authors: , , , , | Summary: A successful commercial deployment of quantum key distribution (QKD) technologies requires integrating QKD links into existing fibers and sharing the same fiber networks with classical data traffic. To mitigate the spontaneous Raman scattering (SpRS) noise from classical data channels, several quantum/classical […]

The high polarisation of the X-rays from the Black Hole X-ray Binary 4U 1630-47 challenges standard thin accretion disc scenario

Kavli Affiliate: Roger Romani | First 5 Authors: Ajay Ratheesh, Michal Dovčiak, Henric Krawczynski, Jakub Podgorný, Lorenzo Marra | Summary: Large, energy-dependent X-ray polarisation is observed in 4U 1630-47, a black hole in an X-ray binary, in the high-soft emission state. In this state, X-ray emission is believed to be dominated by a thermal, geometrically […]
