A dense $mathbf{0.1 M_{rm odot}}$ star in a 51-minute orbital period eclipsing binary

Kavli Affiliate: Saul Rappaport | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Thomas R. Marsh, Saul Rappaport, Warren R. Brown | Summary: In over a thousand known cataclysmic variables (CVs), where a white dwarf is accreting from a hydrogen-rich star, only a dozen have orbital periods below 75 minutes. One way to achieve these […]

Omnigrok: Grokking Beyond Algorithmic Data

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Eric J. Michaud, Max Tegmark, , | Summary: Grokking, the unusual phenomenon for algorithmic datasets where generalization happens long after overfitting the training data, has remained elusive. We aim to understand grokking by analyzing the loss landscapes of neural networks, identifying the mismatch between training […]

Gas Morphology of Milky Way-like Galaxies in the TNG50 Simulation: Signals of Twisting and Stretching

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Thomas K. Waters, Colton Peterson, Razieh Emami, Xuejian Shen, Lars Hernquist | Summary: We present an in-depth analysis of gas morphologies for a sample of 25 Milky Way-like galaxies from the IllustrisTNG TNG50 simulation. We constrain the morphology of cold, warm, hot gas, and gas particles as […]

ALPHA: Searching For Dark Matter with Plasma Haloscopes

Kavli Affiliate: Frank Wilczek | First 5 Authors: Alexander J. Millar, Steven M. Anlage, Rustam Balafendiev, Pavel Belov, Karl van Bibber | Summary: We summarise the recent progress of the Axion Longitudinal Plasma HAloscope (ALPHA) Consortium, a new experimental collaboration to build a plasma haloscope to search for axions and dark photons. The plasma haloscope […]

Revealing AGNs Through TESS Variability

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh, Benjamin J. Shappee, Christopher S. Kochanek | Summary: We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision TESS light curves present a unique […]

An old warm Jupiter orbiting the metal-poor G-dwarf TOI-5542

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Nolan Grieves, François Bouchy, Solène Ulmer-Moll, Samuel Gill, David R. Anderson | Summary: We report the discovery of a 1.32$^{+0.10}_{-0.10}$ $mathrm{M_{rm Jup}}$ planet orbiting on a 75.12 day period around the G3V $10.8^{+2.1}_{-3.6}$ Gyr old star TOI-5542 (TIC 466206508; TYC 9086-1210-1). The planet was first detected […]

TESS spots a mini-neptune interior to a hot saturn in the TOI-2000 system

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang, David J. Armstrong, Rafael Brahm | Summary: Hot jupiters (P < 10 d, M > 60 $mathrm{M}_oplus$) are almost always found alone around their stars, but four out of hundreds known have inner companion planets. These rare companions […]
