Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Yuxiao Li, Max Tegmark, , | Summary: Motivated by interpretability and reliability, we investigate how neural networks represent knowledge during graph learning, We find hints of universality, where equivalent representations are learned across a range of model sizes (from $10^2$ to $10^9$ parameters) and […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Kaitlyn Shin, Calvin Leung, Sunil Simha, Bridget C. Andersen, Emmanuel Fonseca | Summary: Fast radio bursts (FRBs) are unique probes of extragalactic ionized baryonic structure as each signal, through its burst properties, holds information about the ionized matter it encounters along its sightline. FRB 20200723B is […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ellen M. Price, Juliette Becker, Zoë L. de Beurs, Leslie A. Rogers, Andrew Vanderburg | Summary: HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically. We present a […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hans Moritz Günther, Dheeraj Pasham, Alexander Binks, Stefan Czesla, Teruaki Enoto | Summary: Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set limits on the magnetic field strength and thus constrain the […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William Lake, Michael Y. Grudić, Smadar Naoz, Naoki Yoshida, Claire E. Williams | Summary: To date, JWST has detected the earliest known star clusters in our Universe (Adamo et al. 2024, Messa et al. 2024, Vanzella et al. 2024, Mowla et al. 2024). They appear to be […]
Kavli Affiliate: Erin Kara | First 5 Authors: Hagai Netzer, Michael R. Goad, Aaron J. Barth, Edward M. Cackett, Keith Horne | Summary: The local (z=0.0315) AGN Mrk 817, was monitored over more than 500 days with space-borne and ground-based instruments as part of a large international campaign AGN STORM 2. Here, we present a […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rohan P. Naidu, Jorryt Matthee, Ivan Kramarenko, Andrea Weibel, Gabriel Brammer | Summary: Dwarf galaxies hold the key to crucial frontiers of astrophysics, however, their faintness renders spectroscopy challenging. Here we present the JWST Cycle 2 survey, All the Little Things (ALT, PID 3516), which is […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits, Brian P. Powell, Robert Gagliano | Summary: We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, Pout, of only 24.5 days. This "eclipses" the previous record set by lambda Tauri at 33.02 […]
