Cross-correlating the patchy screening and kinetic Sunyaev-Zel’dovich effects as a new probe of reionization

Posted by dbos January 13, 2025January 30, 2025Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: Darby Kramer, Alexander van Engelen, Christopher Cain, Niall MacCrann, Hy Trac | Summary: The kinetic Sunyaev-Zel’dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era. The kSZ effect is a relatively strong signal, but is difficult to disentangle […]

The Guitar’s Magnetic Field Revealed by Starlight Polarization

Posted by dbos January 13, 2025January 30, 2025Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed along the line-of-sight to the pulsar. The polarizing effect of […]

The I-Love universal relation for polytropic stars under Newtonian gravity

Posted by dbos January 13, 2025January 30, 2025Peking

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Rui Xu, Alejandro Torres-Orjuela, Lars Andersson, Pau Amaro Seoane, | Summary: The moment of inertia and tidal deformability of idealized stars with polytropic equations of state (EOSs) are numerically calculated under both Newtonian gravity and general relativity (GR). The results explicitly confirm that the relation between […]

The diverse physical origins of stars in the dynamically hot bulge: CALIFA vs. IllustrisTNG

Posted by January 13, 2025Peking

Le Zhang, Ling Zhu, Annalisa Pillepich, Min Du, Fangzhou Jiang | Summary: [[{“value”:”We compare the internal stellar structures of central galaxies in the TNG50 and TNG100 simulations and field galaxies in the CALIFA survey. The luminosity fractions of the dynamically cold, warm, and hot components in both TNG50 and TNG100 galaxies exhibit general consistency with […]

Turing-Completeness and Undecidability in Coupled Nonlinear Optical Resonators

Posted by January 12, 2025Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Gordon Li, Alireza Marandi, , , | Summary: Networks of coupled nonlinear optical resonators have emerged as an important class of systems in ultrafast optical science, enabling richer and more complex nonlinear dynamics compared to their single-resonator or travelling-wave counterparts. In recent years, these coupled nonlinear optical […]

Long-lived Habitable Zones around White Dwarfs undergoing Neon-22 Distillation

Posted by dbos January 11, 2025MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Andrew Vanderburg, Antoine Bédard, Juliette C. Becker, Simon Blouin, | Summary: White dwarf stars have attracted considerable attention in the past 15 years as hosts for potentially habitable planets, but their low luminosity and continuous cooling are major challenges for habitability. Recently, astronomers have found that about […]

LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network

Posted by dbos January 10, 2025MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Javier Viaña, Kyu-Ha Hwang, Zoë de Beurs, Jennifer C. Yee, Andrew Vanderburg | Summary: Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time-consuming. This reliance on manual inspection often leads to inefficiencies and constrains the ability to scale […]
