TESS Revisits WASP-12: Updated Orbital Decay Rate and Constraints on Atmospheric Variability

Kavli Affiliate: Avi Shporer | First 5 Authors: Ian Wong, Avi Shporer, Shreyas Vissapragada, Michael Greklek-McKeon, Heather A. Knutson | Summary: After observing WASP-12 in the second year of the primary mission, the Transiting Exoplanet Survey Satellite (TESS) revisited the system in late 2021 during its extended mission. In this paper, we incorporate the new […]

Photochemical Runaway in Exoplanet Atmospheres: Implications for Biosignatures

Kavli Affiliate: Sara Seager | First 5 Authors: Sukrit Ranjan, Sara Seager, Zhuchang Zhan, Daniel D. B. Koll, William Bains | Summary: About 2.5 billion years ago, microbes learned to harness plentiful Solar energy to reduce CO$_2$ with H$_2$O, extracting energy and producing O$_2$ as waste. O$_2$ production from this metabolic process was so vigorous […]

Comparing weak lensing peak counts in baryonic correction models to hydrodynamical simulations

Kavli Affiliate: Jia Liu | First 5 Authors: Max E. Lee, Tianhuan Lu, Zoltán Haiman, Jia Liu, Ken Osato | Summary: Next-generation weak lensing (WL) surveys, such as by the Vera Rubin Observatory’s LSST, the $textit{Roman}$ Space Telescope, and the $textit{Euclid}$ space mission, will supply vast amounts of data probing small, highly nonlinear scales. Extracting […]

Low-Pass Filtering SGD for Recovering Flat Optima in the Deep Learning Optimization Landscape

Kavli Affiliate: Jing Wang | First 5 Authors: Devansh Bisla, Jing Wang, Anna Choromanska, , | Summary: In this paper, we study the sharpness of a deep learning (DL) loss landscape around local minima in order to reveal systematic mechanisms underlying the generalization abilities of DL models. Our analysis is performed across varying network and […]

High-power laser experiment forming a supercritical collisionless shock in a magnetized uniform plasma at rest

Kavli Affiliate: T. Higuchi | First 5 Authors: Ryo Yamazaki, S. Matsukiyo, T. Morita, S. J. Tanaka, T. Umeda | Summary: We present a new experimental method to generate quasi-perpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well-magnetized, and it has uniform mass density. The plasma is […]
