Mission Architecture to Characterize Habitability of Venus Cloud Layers via an Aerial Platform

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 […]

Aerial Platform Design Options for a Life-Finding Mission at Venus

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 […]

Asymptotic density of states in 2d CFTs with non-invertible symmetries

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 […]

Evidence for PeV Proton Acceleration from Fermi-LAT Observations of SNR G106.3+2.7

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. […]

Galaxy clustering from the bottom up: A Streaming Model emulator I

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 […]

Orbitofrontal cortex populations are differentially recruited to support actions

Kavli Affiliate: Christina Gremel | Authors: Christian Cazares, Drew C. Schreiner, Mariela Lopez Valencia and Christina M. Gremel | Summary: Summary The ability to use information from one’s prior actions is necessary for decision-making. While Orbitofrontal cortex (OFC) has been hypothesized as key for inferences made using cue and value-related information, whether OFC populations contribute […]
