Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Dan Kondo, Hitoshi Murayama, Cameron Sylber, , | Summary: Arguably, the simplest chiral gauge theories are $mathrm{SO}(10)$ with $N_f$ fermion fields in the spinor representation {bf 16}. We study their dynamics using their supersymmetric limits perturbed by an infinitesimal anomaly-mediated supersymmetry breaking as a guide. We predict […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Hikaru Fukuchi, Kohei Ichikawa, Masayuki Akiyama, Claudio Ricci, Sunmyon Chon | Summary: H1821+643 is the most X-ray luminous non-beamed AGN of $L_mathrm{14-150 keV}= 5.2times 10^{45}$ erg s$^{-1}$ in the Swift/BAT ultra-hard X-ray survey and it is also a hyper-luminous infrared (IR) galaxy $L_mathrm{IR} = 10^{13.2} L_odot$ residing […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Hongbo Cai, Yilun Guan, Toshiya Namikawa, Arthur Kosowsky, | Summary: The power spectrum of cosmic microwave background lensing is a powerful tool for constraining fundamental physics such as the sum of neutrino masses and the dark energy equation of state. Current lensing measurements primarily come from distortions […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Mark G. Klehfoth, Robert M. Wald, , , | Summary: For Euclidean quantum field theories, Holland and Hollands have shown operator product expansion (OPE) coefficients satisfy "flow equations": For interaction parameter $lambda$, the partial derivative of any OPE coefficient with respect to $lambda$ is given by […]
Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Brenna Flaugher, Vivian Miranda, David J. Schlegel, Adam J. Anderson, Felipe Andrade-Oliveira | Summary: The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to understanding the causes of early- and […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Alex Drlica-Wagner, Chanda Prescod-Weinstein, Hai-Bo Yu, Andrea Albert, Arka Banerjee | Summary: Cosmological and astrophysical observations currently provide the the only robust, positive evidence for dark matter. Cosmic probes of dark matter, which seek to determine the fundamental properties of dark matter through observations of the […]
