Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Frank Wilczek, , , | Summary: We demonstrate that the statistical fluctuations in resonant radiation detectors operating in homodyne and heterodyne modes offers additional, complementary information to that obtained from their direct operation as click detectors. We use this to refine tests of the […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Frank Wilczek, , , | Summary: Gravitational radiation from known astrophysical sources is conventionally treated classically. This treatment corresponds, implicitly, to the hypothesis that a particular class of quantum-mechanical states — the so-called coherent states — adequately describe the gravitational radiation field. We propose […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer, Andrea Weibel, Yijia Li | Summary: JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, $z>10$, where few such sources were expected. Here we present the most distant example of this class yet — […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Yizhou Liu, Jeff Gore, Max Tegmark, | Summary: Beyond neural scaling laws, little is known about the laws underlying large language models (LLMs). We introduce Neural Thermodynamic Laws (NTL) — a new framework that offers fresh insights into LLM training dynamics. On the theoretical side, […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ali Ghorashi, Sachin Vaidya, Ziming Liu, Charlotte Loh, Thomas Christensen | Summary: Topological photonic crystals (PhCs) offer robust, disorder-resistant modes engendered by nontrivial band symmetries, but designing PhCs with prescribed topological band properties remains a challenge due to the complexity involved in mapping the continuous real-space design […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sydney Jenkins, Andrew Vanderburg, Ritika Sethi, Sarah Millholland, Joseph E. Rodriguez | Summary: Though missions such as Kepler, K2, and TESS have discovered $>$2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P$lesssim$3 days) orbits. This feature, called the Neptune desert or […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Viraj Karambelkar, Mansi Kasliwal, Kishalay De, Danielle Frostig, Robert Stein | Summary: We present WNTR23bzdiq/WTP19aalzlk, a slow eruption of an early-asymptotic giant branch (AGB) star in M31 identified by the Wide-field Infrared Transient Explorer (WINTER) near-infrared and the NEOWISE mid-infrared surveyors. This source brightened gradually over […]
Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Rachel B Fernandes, Shubham Kanodia, Megan Delamer, Andrew Hotnisky, Te Han | Summary: We present the confirmation of TOI-5573b, a Saturn-sized exoplanet on an 8.79-day orbit around an early M-dwarf (3790 K, 0.59 R$odot$, 0.61 M$odot$, 12.30 J mag). TOI-5573b has a mass of $112^{+18}_{-19}$ M$oplus$ […]
Kavli Affiliate: Lina Necib | First 5 Authors: Dylan Folsom, Carlos Blanco, Mariangela Lisanti, Lina Necib, Mark Vogelsberger | Summary: The sensitivity of direct detection experiments depends on the phase-space distribution of dark matter near the Sun, which can be modeled theoretically using cosmological hydrodynamical simulations of Milky Way-like galaxies. However, capturing the halo-to-halo variation […]
Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, Marc Audard, Hisamitsu Awaki, Ralf Ballhausen, Aya Bamba | Summary: We report a detailed spectroscopic study of the gas dynamics and hydrostatic mass bias of the galaxy cluster Abell 2029, utilizing high-resolution observations from XRISM Resolve. Abell 2029, known for its cool core and relaxed […]
