Tidally Tilted Pulsators

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Gerald Handler, Rahul Jayaraman, Donald W. Kurtz, Jim Fuller, Saul A. Rappaport | Summary: The tidally tilted pulsators are a new type of oscillating star in close binary systems that have their pulsation axis in the orbital plane because of the tidal distortion caused by their […]

Percent-level constraints on baryonic feedback with spectral distortion measurements

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Leander Thiele, Digvijay Wadekar, J. Colin Hill, Nicholas Battaglia, Jens Chluba | Summary: High-significance measurements of the monopole thermal Sunyaev-Zel’dovich CMB spectral distortions have the potential to tightly constrain poorly understood baryonic feedback processes. The sky-averaged Compton-y distortion and its relativistic correction are measures of the total […]

Evidence of large recoil velocity from a black hole merger signal

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Sylvia Biscoveanu, Tousif Islam, Feroz H. Shaik, Carl-Johan Haster | Summary: The final black hole left behind after a binary black hole merger can attain a recoil velocity, or a "kick", reaching values up to 5000 km/s. This phenomenon has important implications for gravitational wave […]

A Neural Network Solves and Generates Mathematics Problems by Program Synthesis: Calculus, Differential Equations, Linear Algebra, and More

Kavli Affiliate: Avi Shporer | First 5 Authors: Iddo Drori, Sunny Tran, Roman Wang, Newman Cheng, Kevin Liu | Summary: We demonstrate that a neural network pre-trained on text and fine-tuned on code solves Mathematics problems by program synthesis. We turn questions into programming tasks, automatically generate programs, and then execute them, perfectly solving university-level […]

A Neural Network Solves, Explains, and Generates University Math Problems by Program Synthesis and Few-Shot Learning at Human Level

Kavli Affiliate: Avi Shporer | First 5 Authors: Iddo Drori, Sarah Zhang, Reece Shuttleworth, Leonard Tang, Albert Lu | Summary: We demonstrate that a neural network pre-trained on text and fine-tuned on code solves mathematics course problems, explains solutions, and generates new questions at a human level. We automatically synthesize programs using few-shot learning and […]

TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs

Kavli Affiliate: Avi Shporer | First 5 Authors: Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson, Bryson L. Cale, Dax L. Feliz | Summary: We validate the presence of a two-planet system orbiting the 0.2–1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune (TOI 560 b, […]

Production of Ammonia Makes Venusian Clouds Habitable and Explains Observed Cloud-Level Chemical Anomalies

Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Paul B. Rimmer, Sara Seager, | Summary: The atmosphere of Venus remains mysterious, with many outstanding chemical connundra. These include: the unexpected presence of ~10 ppm O2 in the cloud layers; an unknown composition of large particles in the lower cloud layers; […]

On the formation of massive quiescent galaxies with diverse morphologies in the TNG50 simulation

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Minjung Park, Sandro Tacchella, Erica J. Nelson, Lars Hernquist, Rainer Weinberger | Summary: Observations have shown that the star-formation activity and the morphology of galaxies are closely related, but the underlying physical connection is not well understood. Using the TNG50 simulation, we explore the quenching and the […]

Could the Magnetic Star HD 135348 Possess a Rigidly Rotating Magnetosphere?

Kavli Affiliate: George R. Ricker | First 5 Authors: Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth, Markus Schöller, Silva Järvinen | Summary: We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star exhibited variations consistent with stars known to […]
