Provable properties of asymptotic safety in $f(R)$ approximation

Kavli Affiliate: R. Morris | First 5 Authors: Alex Mitchell, Tim R. Morris, Dalius Stulga, , | Summary: We study an $f(R)$ approximation to asymptotic safety, using a family of non-adaptive cutoffs, kept general to test for universality. Matching solutions on the four-dimensional sphere and hyperboloid, we prove properties of any such global fixed point […]

The population of merging compact binaries inferred using gravitational waves through GWTC-3

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott | Summary: We report on the population properties of 76 compact binary mergers detected with gravitational waves below a false alarm rate of 1 per year through GWTC-3. The catalog contains three […]

Supernova-driven turbulent metal mixing in high redshift galactic disks: metallicity fluctuations in the interstellar medium and its imprints on metal poor stars in the Milky Way

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Anne Noer Kolborg, Davide Martizzi, Enrico Ramirez-Ruiz, Hugo Pfister, Charli Sakari | Summary: The extent to which turbulence mixes gas in the face of recurrent infusions of fresh metals by supernovae (SNe) could help provide important constraints on the local star formation conditions. This includes predictions […]

VLA Radio Study of a Sample of Nearby X-ray and Optically Bright Early-Type Galaxies

Kavli Affiliate: Steven W. Allen | First 5 Authors: Romana Grossová, Norbert Werner, Francesco Massaro, Kiran Lakhchaura, Tomáš Plšek | Summary: Many massive early-type galaxies host central radio sources and hot X-ray atmospheres indicating the presence of radio-mechanical active galactic nucleus (AGN) feedback. The duty cycle and detailed physics of the radio-mode AGN feedback is […]

The Simons Observatory: Galactic Science Goals and Forecasts

Kavli Affiliate: Susan E. Clark | First 5 Authors: Brandon S. Hensley, Susan E. Clark, Valentina Fanfani, Nicoletta Krachmalnicoff, Giulio Fabbian | Summary: Observing in six frequency bands from 27 to 280 GHz over a large sky area, the Simons Observatory (SO) is poised to address many questions in Galactic astrophysics in addition to its […]

Testing solar surface flux transport models in the first days after active region emergence

Kavli Affiliate: Robert Cameron | First 5 Authors: Nils Gottschling, Hannah Schunker, Aaron C. Birch, Robert Cameron, Laurent Gizon | Summary: Active regions (ARs) play an important role in the magnetic dynamics of the Sun. Solar surface flux transport models (SFTMs) are used to describe the evolution of the radial magnetic field at the solar […]

A Simulation-Based Method for Correcting Mode Coupling in CMB Angular Power Spectra

Kavli Affiliate: C. L. Kuo | First 5 Authors: J. S. -Y. Leung, J. Hartley, J. M. Nagy, C. B. Netterfield, J. A. Shariff | Summary: Modern CMB analysis pipelines regularly employ complex time-domain filters, beam models, masking, and other techniques during the production of sky maps and their corresponding angular power spectra. However, these […]

On the single classical field description of interacting scalar fields

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: We test the degree to which interacting Bosonic systems can be approximated by a classical field as total occupation number is increased. This is done with our publicly available code repository, href{https://github.com/andillio/QIBS}{QIBS}, a massively parallel solver for […]
