The slow brightening of WNTR23bzdiq / WTP19aalzlk : Possible onset of common-envelope evolution in an asymptotic giant branch star?

Posted by dbos May 14, 2025MIT

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 […]

The Dual Primordial Black Hole Formation Scenario

Posted by dbos May 14, 2025May 28, 2025Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Xinpeng Wang, Misao Sasaki, Ying-li Zhang, , | Summary: We report a novel mechanism where two families of primordial black holes (PBHs) may form at nearly the same comoving scales but at two different epochs. It is realized in two-stage inflation where a non-inflationary stage is sandwiched […]

On the Learning with Augmented Class via Forests

Posted by dbos May 14, 2025May 28, 2025Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Fan Xu, Wuyang Chen, Wei Gao, , | Summary: Decision trees and forests have achieved successes in various real applications, most working with all testing classes known in training data. In this work, we focus on learning with augmented class via forests, where an augmented class may […]

High Chern Number Quantum Anomalous Hall States in Haldane-Graphene Multilayers

Posted by dbos May 14, 2025May 28, 2025UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Yuejiu Zhao, Long Zhang, Fu-Chun Zhang, , | Summary: Quantum anomalous Hall (QAH) systems with high Chern number ($|C|>1$) are rare. This Letter introduces a Haldane-graphene multilayer heterostructure hosting QAH states with arbitrary Chern number. In a rhombohedral-stacked graphene $N$-layer, the Dirac points at $K_{pm}$ become $N^text{th}$-order […]

Late-time suppression of structure growth as a solution for the $S_8$ tension

Posted by dbos May 14, 2025May 28, 2025Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Masahiro Takada, Toshiki Kurita, Sunao Sugiyama, | Summary: The $S_8$ value inferred from the Subaru Hyper Suprime-Cam (HSC) Year 3 cosmic shear data, under the assumption of the flat $Lambda$CDM model, is 2-3$sigma$ lower than that inferred from observations of the early-time universe, such as […]

Stacking-Selective Epitaxy of Rare-Earth Diantimonides

Posted by dbos May 13, 2025May 28, 2025Caltech

Kavli Affiliate: Joseph Falson | First 5 Authors: Reiley Dorrian, Jinwoong Kim, Adrian Llanos, Veronica Show, Mizuki Ohno | Summary: Deterministic control of the layering configuration of two-dimensional quantum materials plays a central role in studying their emergent electronic properties. Here we demonstrate in-situ control over competing stacking configurations in thin film crystals of the […]

Searching for GEMS: Confirmation of TOI-5573b, a Cool, Saturn-like Planet Orbiting An M-dwarf

Posted by dbos May 13, 2025May 28, 2025MIT

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$oplus$ […]

Bounding Neyman-Pearson Region with $f$-Divergences

Posted by dbos May 13, 2025May 28, 2025UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Andrew Mullhaupt, Cheng Peng, , , | Summary: The Neyman-Pearson region of a simple binary hypothesis testing is the set of points whose coordinates represent the false positive rate and false negative rate of some test. The lower boundary of this region is given by the Neyman-Pearson […]
