Kavli Affiliate: Bruce Macintosh | First 5 Authors: Jason J. Wang, Peter Gao, Jeffrey Chilcote, Julien Lozi, Olivier Guyon | Summary: The atmospheres of gas giant planets are thought to be inhomogeneous due to weather and patchy clouds. We present two full nights of coronagraphic observations of the HR 8799 planets using the CHARIS integral […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Benjamin Kuznets-Speck, David T Limmer, , , | Summary: We develop a theory for inferring equilibrium transition rates from trajectories driven by a time dependent force using results from stochastic thermodynamics. Applying the Kawasaki relation to approximate the nonequilibrium distribution function in terms of the equilibrium […]
Kavli Affiliate: Sara Seager | First 5 Authors: Rachana Agrawal, Weston P. Buchanan, Archit Arora, Athul P. Girija, Maxim de Jong | Summary: Venus is known for its extreme surface temperature and its sulfuric acid clouds. But the cloud layers on Venus have similar temperature and pressure conditions to those on the surface of Earth […]
Kavli Affiliate: Sara Seager | First 5 Authors: Weston P. Buchanan, Maxim de Jong, Rachana Agrawal, Janusz J. Petkowski, Archit Arora | Summary: Mounting evidence of chemical disequilibria in the Venusian atmosphere has heightened interest in the search for life within the planet’s cloud decks. Balloon systems are currently considered to be the superior class […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Christopher E. Carr, David H. Grinspoon, Bethany L. Ehlmann | Summary: Finding evidence of extraterrestrial life would be one of the most profound scientific discoveries ever made, advancing humanity into a new epoch of cosmic awareness. The Venus Life Finder (VLF) missions […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ying-Hsuan Lin, Masaki Okada, Sahand Seifnashri, Yuji Tachikawa, | Summary: It is known that the asymptotic density of states of a 2d CFT in an irreducible representation $rho$ of a finite symmetry group $G$ is proportional to $(dimrho)^2$. We show how this statement can be generalized when […]
Kavli Affiliate: Eric Charles | First 5 Authors: Ke Fang, Matthew Kerr, Roger Blandford, Henrike Fleischhack, Eric Charles | Summary: The existence of a "knee" at energy ~1 PeV in the cosmic-ray spectrum suggests the presence of Galactic PeV proton accelerators called "PeVatrons". Supernova Remnant (SNR) G106.3+2.7 is a prime candidate for one of these. […]

Kavli Affiliate: Masahiro Takada | First 5 Authors: Carolina Cuesta-Lazaro, Takahiro Nishimichi, Yosuke Kobayashi, Cheng-Zong Ruan, Alexander Eggemeier | Summary: In this series of papers, we present a simulation-based model for the non-linear clustering of galaxies based on separate modelling of clustering in real space and velocity statistics. In the first paper, we present an […]
Kavli Affiliate: James Bock | First 5 Authors: Sam Condon, Marco Viero, James Bock, Howard Hui, Phil Korngut | Summary: Selected as the next NASA Medium Class Explorer mission, SPHEREx, the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer is planned for launch in early 2025. SPHEREx calibration data products […]
