Kavli Affiliate: Sara Seager | First 5 Authors: Zifan Lin, Saverio Cambioni, Sara Seager, , | Summary: Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories – metal-rich formation hypothesis and naked core hypothesis – that explain how formation and evolution can alter the compositions and […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Amir Arbabi, Andrei Faraon, , , | Summary: It was recently claimed1 that reported focusing efficiency values of high numerical aperture metalenses are inconsistent with a theoretical bound, and their measurement results are incorrectly interpreted. We review the article and conclude that these claims are not well […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Riya Dinesh Deshpande, Faheem A. Khan, Qasim Zeeshan Ahmed, , | Summary: As the number of devices getting connected to the vehicular network grows exponentially, addressing the numerous challenges of effectively allocating spectrum in dynamic vehicular environment becomes increasingly difficult. Traditional methods may not suffice to tackle […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano, Eduardo J. S. Villaseñor, | Summary: The relation between the Husain-Kuchav{r} model and some extensions thereof that incorporate a dynamical time variable is explored. To this end, we rely on the geometric approach to the Hamiltonian dynamics of […]

Kavli Affiliate: Ke Wang | First 5 Authors: Xuefang Xu, Ke Wang, Qian Gou, Tapas Baug, Di Li | Summary: Dense clumps distributed along filaments are the immediate medium for star formation. Kinematic properties of the clumps, such as velocity gradient and angular momentum, combined with filament orientation, provide important clues to the formation mechanism […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: A. M. Cook, Dayi Li, Gwendolyn M. Eadie, David C. Stenning, Paul Scholz | Summary: This paper introduces an approach to analyze nonhomogeneous Poisson processes (NHPP) observed with noise, focusing on previously unstudied second-order characteristics of the noisy process. Utilizing a hierarchical Bayesian model with noisy […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Michal Zajaček, Petra Suková, Vladimír Karas, Dheeraj R. Pasham, Francesco Tombesi | Summary: The first detection of the quasiperiodic ultrafast outflow in the ASASSN-20qc system was reported by Pasham et al. (2024). The outflow is revealed in the soft X-ray spectra as an absorption feature, which […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Ronald A. Remillard, Margarita Hernanz, Jean in ‘t Zand, Paul S. Ray, Valter Bonvicini | Summary: The Wide Field Monitor (WFM) is one of the three instruments on the Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) mission, which was proposed in response to the NASA […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Adam Distler, Melinda Soares-Furtado, Andrew Vanderburg, Jack Schulte, Juliette Becker | Summary: We present the discovery and characterization of TOI-4364,b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit observations and ground-based follow-up photometry. The planet orbits a bright M dwarf […]
