A gravitational wave detectable candidate Type Ia supernova progenitor

Kavli Affiliate: Gabor Furesz | First 5 Authors: Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty, Vik S. Dhillon, Paul Draghis | Summary: Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evidence supports the “double-degenerate” scenario, where two white dwarfs […]

Signatures of black hole seeding in the local Universe: Predictions from the BRAHMA cosmological simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K Bhowmick, Laura Blecha, Paul Torrey, Rachel S Somerville, Luke Zoltan Kelley | Summary: The first "seeds" of supermassive black holes (BHs) continue to be an outstanding puzzle, and it is currently unclear whether the imprints of early seed formation survive today. Here we examine the […]

Rapid Rotation of Polarization Orientations in PSR B1919+21’s Single Pulses: Implications On Pulsar’s Magnetospheric Dynamics

Kavli Affiliate: Kejia Lee | First 5 Authors: Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks, Kejia Lee, Jiguang Lu | Summary: We analyse and model rapid rotations of polarization orientations in PSR B1919+21’s single pulses, based on FAST observation data. In more than one third of B1919+21’s single pulses, polarization angle (PA) is found to rotate […]

A Short-lived Rejuvenation during the Decades-long Changing-look Transition in the Nucleus of Mrk 1018

Kavli Affiliate: Luis C. Ho | First 5 Authors: Kai-Xing Lu, Yan-Rong Li, Qingwen Wu, Luis C. Ho, Zhi-Xiang Zhang | Summary: Changing-look active galactic nuclei (CL-AGNs), characterized by emerging or disappearing of broad lines accompanied with extreme continuum flux variability, have drawn much attention for their potential of revealing physical processes underlying AGN evolution. […]

A Trade-Off Between Path Entanglement and Quantum Sensitivity

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Benjamin Lou, Hudson A. Loughlin, Nergis Mavalvala, , | Summary: Entanglement often increases quantum measurement schemes’ sensitivity. However, we find that in precision measurements with zero-mean Gaussian states, such as squeezed states, entanglement between different paths degrades measurement sensitivity. We prove an inverse relationship between entanglement entropy […]

The Higgs-Amplitude mode in the optical conductivity in the presence of a supercurrent: Gauge invariant forumulation

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the amplitude-Higgs mode in superconductors has been a central challenge in condensed matter physics. Unlike the phase mode in the electromagnetic (EM) response, the amplitude mode is not needed to satisfy gauge invariance. Indeed, it couples to […]
