Kavli Affiliate: Roland Vanderspek | First 5 Authors: Ashley Chontos, Daniel Huber, Samuel K. Grunblatt, Nicholas Saunders, Joshua N. Winn | Summary: We present a dedicated transit and radial velocity survey of planets orbiting subgiant stars observed by the TESS Mission. Using $sim$$16$ nights on Keck/HIRES, we confirm and characterize $12$ new transiting planets — […]
Kavli Affiliate: David Shoemaker | First 5 Authors: Monica Colpi, Karsten Danzmann, Martin Hewitson, Kelly Holley-Bockelmann, Philippe Jetzer | Summary: The Laser Interferometer Space Antenna (LISA) is the first scientific endeavour to detect and study gravitational waves from space. LISA will survey the sky for Gravitational Waves in the 0.1 mHz to 1 Hz frequency […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Qingru Hu, Malena Rice, Xian-Yu Wang, Songhu Wang, Avi Shporer | Summary: TOI-677 b is part of an emerging class of “tidally-detached” gas giants ($a/R_star gtrsim 11$) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Anmol Desai, Emma V. Turtelboom, Caleb K. Harada, Courtney D. Dressing, David R. Rice | Summary: We present and confirm TOI-1751 b, a transiting sub-Neptune orbiting a slightly evolved, solar-type, metal-poor star ($T_{eff} = 5996 pm 110$ K, $log(g) = 4.2 pm 0.1$, V = 9.3 […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Anirudh Chiti, , | Summary: We report on the discovery of the first ultra metal-poor (UMP) star 2MASS~J20500194$-$6613298 (J2050$-$6613; mbox{[Fe/H] = $-4.05$}) selected from the Gaia BP/RP spectral catalog that belongs to the ancient Atari disk component. We obtained a high-resolution spectrum […]
Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Ziming Liu, Max Tegmark, , | Summary: We present GenEFT: an effective theory framework for shedding light on the statics and dynamics of neural network generalization, and illustrate it with graph learning examples. We first investigate the generalization phase transition as data size increases, […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Eric J. Michaud, Isaac Liao, Vedang Lad, Ziming Liu, Anish Mudide | Summary: We present MIPS, a novel method for program synthesis based on automated mechanistic interpretability of neural networks trained to perform the desired task, auto-distilling the learned algorithm into Python code. We test MIPS on […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Jinyeop Song, Ziming Liu, Max Tegmark, Jeff Gore, | Summary: Neural scaling laws characterize how model performance improves as the model size scales up. Inspired by empirical observations, we introduce a resource model of neural scaling. A task is usually composite hence can be decomposed into many […]
