Kavli Affiliate: Melania Nynka | First 5 Authors: Kaya Mori, Charles Hailey, Gabriel Bridges, Shifra Mandel, Amani Garvin | Summary: Electrons accelerated on Earth by a rich variety of wave scattering or stochastic processes generate hard non-thermal X-ray bremsstrahlung up to >~ 1 MeV and power Earth’s various types of aurorae. Although Jupiter’s magnetic field […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Maura Lally, Andrew Vanderburg, , , | Summary: We reassess the claimed detection of variability in the atmosphere of the hot Jupiter HAT-P-7 b, reported by Armstrong et al. (2016). Although astronomers expect hot Jupiters to have changing atmospheres, variability is challenging to detect. We looked for […]
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: Eli Rykoff | First 5 Authors: Zhuowen Zhang, Hao-Yi Wu, Yuanyuan Zhang, Joshua Frieman, Chun-Hao To | Summary: Counts of galaxy clusters offer a high-precision probe of cosmology, but control of systematic errors will determine the accuracy of this measurement. Using Buzzard simulations, we quantify one such systematic, the triaxiality distribution of clusters […]

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Marc Basquens, Bogar Díaz, Eduardo J. S. Villaseñor, | Summary: We study the internally abelianized version of a range of gravitational theories, written in connection tetrad form, and study the possible interaction terms that can be added to them in a consistent […]
