Kavli Affiliate: Xian Chen | First 5 Authors: Yi Gong, Zhoujian Cao, Xian Chen, , | Summary: Binary black hole may form near a supermassive black hole. The background black hole (BH) will affect the gravitational wave (GW) generated by the binary black hole. It is well known that the Penrose process may provide extra […]
Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Tobias Dyckerhoff, Mikhail Kapranov, Vadim Schechtman, Yan Soibelman, | Summary: We develop the theory of semi-orthogonal decompositions and spherical functors in the framework of stable $infty$-categories. Building on this, we study the relative Waldhausen S-construction $S_bullet(F)$ of a spherical functor $F$ and equip it with a natural […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Zachary P. Vanderbosch, Saul Rappaport, Joseph A. Guidry, Bruce L. Gary, Simon Blouin | Summary: We present follow-up photometry and spectroscopy of ZTF J0328$-$1219 strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transient Facility photometry, along with follow-up high speed […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Carl L. Rodriguez, Newlin C. Weatherford, Scott C. Coughlin, Pau Amaro Seoane, Katelyn Breivik | Summary: We describe the public release of the Cluster Monte Carlo Code (CMC) a parallel, star-by-star $N$-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using H’enon’s method, […]
Kavli Affiliate: Eric Miller | First 5 Authors: Yukikatsu Terada, Matt Holland, Michael Loewenstein, Makoto Tashiro, Hiromitsu Takahashi | Summary: XRISM is an X-ray astronomical mission by the JAXA, NASA, ESA and other international participants, that is planned for launch in 2022 (Japanese fiscal year), to quickly restore high-resolution X-ray spectroscopy of astrophysical objects. To […]
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 […]
