Kavli Affiliate: Paul L. Schechter | First 5 Authors: Chirag Falor, Paul L. Schechter, , , | Summary: The quadruple image configurations of gravitational lenses with vanishing ellipticity are examined. Even though such lenses asymptotically approach circularity, the configurations are stable if the position of the source relative to the vanishing diamond caustic is held […]
Kavli Affiliate: John Richardson | First 5 Authors: Nicholas Waytowich, James Hare, Vinicius G. Goecks, Mark Mittrick, John Richardson | Summary: Traditionally, learning from human demonstrations via direct behavior cloning can lead to high-performance policies given that the algorithm has access to large amounts of high-quality data covering the most likely scenarios to be encountered […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant Kumar Bhowmick, Laura Blecha, Yueying Ni, Tiziana Di Matteo, Paul Torrey | Summary: We explore implications of a range of black hole (BH) seeding prescriptions on the formation of the brightest $zgtrsim6$ quasars in cosmological hydrodynamic simulations. The underlying galaxy formation model is the same as […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Joseph E. Rodriguez, Samuel N. Quinn, Andrew Vanderburg, George Zhou, Jason D. Eastman | Summary: We present the discovery and characterization of six short-period, transiting giant planets from NASA’s Transiting Exoplanet Survey Satellite (TESS) — TOI-1811 (TIC 376524552), TOI-2025 (TIC 394050135), TOI-2145 (TIC 88992642), TOI-2152 (TIC 395393265), […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, James E. Lawler, Elizabeth A. Den Hartog, Vinicius M. Placco, Rebecca Surman | Summary: We present a nearly complete rapid neutron-capture process (r-process) chemical inventory of the metal-poor ([Fe/H] = -1.46 +/- 0.10) r-process-enhanced ([Eu/Fe] = +1.32 +/- 0.08) halo star HD 222925. This […]

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Colin Littlefield, D. W. Hoard, Peter Garnavich, Paula Szkody, Paul A. Mason | Summary: There have been relatively few published long-duration, uninterrupted light curves of magnetic cataclysmic variable stars in which the accreting white dwarf’s rotational frequency is slightly desynchronized from the binary orbital frequency (asynchronous […]
Kavli Affiliate: Andrew Vanderburg, Sara Seager | First 5 Authors: Benjamin J. Hord, Knicole D. Colón, Travis A. Berger, Veselin Kostov, Michele L. Silverstein | Summary: Hot Jupiters are generally observed to lack close planetary companions, a trend that has been interpreted as evidence for high-eccentricity migration. We present the discovery and validation of WASP-132 […]
