Kavli Affiliate: Katrin Heitmann | First 5 Authors: Nicholas Frontiere, J. D. Emberson, Michael Buehlmann, Joseph Adamo, Salman Habib | Summary: We introduce CRK-HACC, an extension of the Hardware/Hybrid Accelerated Cosmology Code (HACC), to resolve gas hydrodynamics in large-scale structure formation simulations of the universe. The new framework couples the HACC gravitational N-body solver with […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Li-Hsin Chen, Mattis Magg, Tilman Hartwig, Simon C. O. Glover, Alexander P. Ji | Summary: We study the stellar mass-to-halo mass relation at $z=0$ in 30 Milky Way-like systems down to the ultra-faint ($M_* < 10^5 M_odot$) regime using the semi-analytic model A-SLOTH. A new model […]
Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Sarah M. Harrison, Jeffrey A. Harvey, Natalie M. Paquette, , | Summary: We present a brief overview of Moonshine with an emphasis on connections to physics. Moonshine collectively refers to a set of phenomena connecting group theory, analytic number theory, and vertex operator algebras or conformal […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Samuel Passaglia, Wayne Hu, , , | Summary: Ultralight axions are theoretically interesting and phenomenologically rich dark sector candidates, but they are difficult to track across cosmological timescales because of their fast oscillations. We resolve this problem by developing a novel method to evolve them efficiently and […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka, Jure Zupan, Gonzalo Alonso-Alvarez | Summary: Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Michele Moresco, Lorenzo Amati, Luca Amendola, Simon Birrer, John P. Blakeslee | Summary: The detection of the accelerated expansion of the Universe has been one of the major breakthroughs in modern cosmology. Several cosmological probes (CMB, SNe Ia, BAO) have been studied in depth to better understand […]
Kavli Affiliate: Clarence L. Chang | First 5 Authors: Yi Li, Volodymyr G. Yefremenko, Marharyta Lisovenko, Cody Trevillian, Tomas Polakovic | Summary: We demonstrate microwave-mediated distant magnon-magnon coupling on a superconducting circuit platform, incorporating chip-mounted single-crystal Y$_3$Fe$_5$O$_{12}$ (YIG) spheres. Coherent level repulsion and dissipative level attraction between the magnon modes of the two YIG spheres […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: The past 50 years has seen cosmology go from a field known for the errors being in the exponents to precision science. The transformation, powered by ideas, technology, a paradigm shift and culture change, has revolutionized our understanding […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Mesut Çalışkan, Jose María Ezquiaga, Otto A. Hannuksela, Daniel E. Holz, | Summary: Strong gravitational lensing of gravitational waves (GWs) has been forecasted to become detectable in the upcoming observing runs. However, definitively distinguishing pairs of lensed sources from random associations is a challenging problem. We […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: $AdS_3$ string theory in the stringy regime $k=(R_{AdS}/ell_{str})^2 < 1$ provides a laboratory for the study of holography in which both sides of AdS/CFT duality are under fairly good control. Worldsheet string theory is solvable, and for closed […]
