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 […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg, Andrew W. Boyle, Ana Isabel Lopez Murillo | Summary: Young (<500 Myr) multi-planet transiting systems are valuable environments for understanding planet evolution by offering an opportunity to make direct comparisons between planets from the same formation conditions. TOI-2076 is […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mariona Badenas-Agusti, Siyi Xu, Andrew Vanderburg, Kishalay De, Patrick Dufour | Summary: We present the first application of the Machine Learning (ML) pipeline $texttt{cecilia}$ to determine the physical parameters and photospheric composition of five metal-polluted He-atmosphere white dwarfs without well-characterised elemental abundances. To achieve this, we perform […]
Kavli Affiliate: Lina Necib | First 5 Authors: Micah Oeur, Sarah R. Loebman, Adrian M. Price-Whelan, Arpit Arora, Lina Necib | Summary: Orbital Torus Imaging (OTI) is a dynamical inference method for determining the Milky Way’s gravitational potential using stellar survey data. OTI uses gradients in stellar astrophysical quantities, such as element abundances, as functions […]
