Angular spectrum of quantum fluctuations in causal structure

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Nathaniel Selub, , | Summary: Scaling arguments are used to constrain the angular spectrum of distortions on boundaries of macroscopic causal diamonds, produced by Planck-scale vacuum fluctuations of causally-coherent quantum gravity. The small-angle spectrum of displacement is derived from a form of scale […]

Improved bounds on the bosonic dark matter with pulsars in the Milky Way

Kavli Affiliate: Lijing Shao | First 5 Authors: Dicong Liang, Lijing Shao, , , | Summary: Neutron stars (NSs) can be used to constrain dark matter (DM) since a NS can transform into a black hole (BH) if it captures sufficient DM particles and exceeds the Chandrasekhar limit. We extend earlier work and for the […]

Active galactic nuclei feedback in an elliptical galaxy (III): the impacts and fate of cosmological inflow

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bocheng Zhu, Feng Yuan, Suoqing Ji, Yingjie Peng, Luis C. Ho | Summary: The cosmological inflow of a galaxy is speculated to be able to enter the galaxy and enhance the star formation rate (SFR) and black hole accretion rate (BHAR). In this paper, by performing high-resolution […]

Angular correlations on causally-coherent inflationary horizons

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen, | Summary: We develop a model for correlations of cosmic microwave background anisotropy on the largest angular scales, based on standard causal geometrical relationships in slow-roll inflation. Unlike standard models based on quantized field modes, it describes perturbations […]

Prompt Detection of Fast Optical Bursts with the Vera C. Rubin Observatory

Kavli Affiliate: Steven M. Kahn | First 5 Authors: Guillem Megias Homar, Joshua E. Meyers, Steven M. Kahn, , | Summary: The transient optical sky has remained largely unexplored on very short timescales. While there have been some experiments searching for optical transients from minutes to years, none have had the capability to distinguish millisecond […]

First measurement of the nuclear-recoil ionization yield in silicon at 100 eV

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: M. F. Albakry, I. Alkhatib, D. Alonso, D. W. P. Amaral, P. An | Summary: We measured the nuclear–recoil ionization yield in silicon with a cryogenic phonon-sensitive gram-scale detector. Neutrons from a mono-energetic beam scatter off of the silicon nuclei at angles corresponding to energy depositions […]
