Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Ashley Villar, Yin Li, Yan-Fei Jiang, Shirley Ho | Summary: Among the most extreme objects in the Universe, active galactic nuclei (AGN) are luminous centers of galaxies where a black hole feeds on surrounding matter. The variability patterns of the light emitted by […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dmitry Galakhov, Wei Li, Masahito Yamazaki, , | Summary: We introduce a class of new algebras, the shifted quiver Yangians, as the BPS algebras for type IIA string theory on general toric Calabi-Yau three-folds. We construct representations of the shifted quiver Yangian from general subcrystals of the […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Thomas A. Callister, Carl-Johan Haster, Ken K. Y. Ng, Salvatore Vitale, Will M. Farr | Summary: Hierarchical analysis of the binary black hole (BBH) detections by the Advanced LIGO and Virgo detectors has offered an increasingly clear picture of their mass, spin, and redshift distributions. Fully understanding […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Bohan Wang, Qi Meng, Wei Chen, Max Tegmark | Summary: Energy conservation is a basic physics principle, the breakdown of which often implies new physics. This paper presents a method for data-driven "new physics" discovery. Specifically, given a trajectory governed by unknown forces, our Neural […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia, | Summary: We propose the use of the Earth as a transducer for ultralight dark-matter detection. In particular we point out a novel signal of kinetically mixed dark-photon dark matter: a monochromatic oscillating magnetic […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Sam Young, Eiichiro Komatsu, Klaus Dolag, , | Summary: The thermal Sunyaev-Zeldovich effect contains information about the thermal history of the universe, observable in maps of the Compton $y$ parameter; however, it does not contain information about the redshift of the sources. Recent papers have utilized a […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Margarita Sobolenko, Peter Berczik, Rainer Spurzem, , | Summary: One of the main possible way of creating the supermassive black hole (SMBH) is a so call hierarchical merging scenario. Central SMBHs at the final phase of interacting and coalescing host-galaxies are observed as SMBH binary (SMBHB) candidates […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Yutaka Tsuzuki, Shin Watanabe, Shimpei Oishi, Nobuyuki Nakamura, Naoki Numadate | Summary: The methods to measure the polarization of the x-rays from highly charged heavy ions with a significantly higher accuracy than the existing technology is needed to explore relativistic and quantum electrodynamics (QED) effects including the […]
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Franz Herzog, Tom Melia, Jasper Roosmale Nepveu, | Summary: We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series […]
