Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: John F. R. Duncan, Jeffrey A. Harvey, Brandon C. Rayhaun, , | Summary: The Thompson sporadic group admits special relationships to modular forms of two kinds. On the one hand, last century’s generalized moonshine for the monster equipped the Thompson group with a module for which […]
Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: John F. R. Duncan, Jeffrey A. Harvey, Brandon C. Rayhaun, , | Summary: Motivated by the appearance of penumbral moonshine, and by evidence that penumbral moonshine enjoys an extensive relationship to generalized monstrous moonshine via infinite products, we establish a general construction in this work which […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Jose María Ezquiaga, Daniel E. Holz, , , | Summary: We explore the use of the mass spectrum of neutron stars and black holes in gravitational-wave compact binary sources as a cosmological probe. These standard siren sources provide direct measurements of luminosity distance. In addition, features […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Peter Abbamonte, Daniel Baxter, Yonatan Kahn, Gordan Krnjaic, Noah Kurinsky | Summary: In light of recent results from low-threshold dark matter detectors, we revisit the possibility of a common dark matter origin for multiple excesses across numerous direct detection experiments, with a focus on the excess rates […]
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 […]
