Kavli Affiliate: Chiaki Hikage | First 5 Authors: Wentao Luo, John D. Silverman, Surhud More, Andy Goulding, Hironao Miyatake | Summary: We assess the dark matter halo masses of luminous AGNs over the redshift range 0.2 to 1.2 using galaxy-galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). We measure […]

Kavli Affiliate: Austin Joyce | First 5 Authors: Austin Joyce, Alberto Nicolis, Alessandro Podo, Luca Santoni, | Summary: We revisit certain subtleties of renormalization that arise when one derives a low-energy effective action by integrating out the heavy fields of a more complete theory. Usually these subtleties are circumvented by matching some physical observables, such […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Yiwen Huang, Hsin-Yu Chen, Carl-Johan Haster, Ling Sun, Salvatore Vitale | Summary: Gravitational-wave (GW) detections of electromagnetically bright compact binary coalescences can provide an independent measurement of the Hubble constant $H_0$. In order to obtain a measurement that could help arbitrating the existing tension on $H_0$, one […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Zihang Wang, Lijing Shao, , , | Summary: The cosmological constant is not necessarily small in the early universe. If a scalar field obtains a vacuum expectation value after a phase transition (PT), a possibly large cosmological constant could present before PT. The early cosmological constant (ECC) […]
Kavli Affiliate: Subo Dong | First 5 Authors: Andrew Gould, Youn Kil Jung, Kyu-Ha Hwang, Subo Dong, Michael D. Albrow | Summary: We complete the survey for finite-source/point-lens (FSPL) giant-source events in 2016-2019 KMTNet microlensing data. The 30 FSPL events show a clear gap in Einstein radius, $9,mu{rm as}<theta_{rm E} <26,mu{rm as}$, which is consistent […]
Kavli Affiliate: Tom Melia | First 5 Authors: Anne-Katherine Burns, David E. Kaplan, Tom Melia, Surjeet Rajendran, | Summary: The quantum description of time evolution in non-linear gravitational systems such as cosmological space-times is not well understood. We show, in the simplified setting of mini-superspace, that time evolution of this system can be obtained using […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Andrew K. Tan, Max Tegmark, Isaac L. Chuang, , | Summary: At the heart of both lossy compression and clustering is a trade-off between the fidelity and size of the learned representation. Our goal is to map out and study the Pareto frontier that quantifies this trade-off. […]
