Increasing single-photon production with cavity-QED

Kavli Affiliate: John E. Bowers | First 5 Authors: Chen Shang, Weng W. Chow, Galan Moody, John E. Bowers, | Summary: A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to […]

Quadrotor Morpho-Transition: Learning vs Model-Based Control Strategies

Kavli Affiliate: Morteza Gharib | First 5 Authors: Ioannis Mandralis, Richard M. Murray, Morteza Gharib, , | Summary: Quadrotor Morpho-Transition, or the act of transitioning from air to ground through mid-air transformation, involves complex aerodynamic interactions and a need to operate near actuator saturation, complicating controller design. In recent work, morpho-transition has been studied from […]

TDCOSMO 2025: Cosmological constraints from strong lensing time delays

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer, Michele Cappellari, Frédéric Courbin | Summary: We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar velocity dispersions measured from spectra obtained with the James Webb […]

Chicago-Carnegie Hubble Program (CCHP) A Multi-Wavelength Search for the Effects of Metallicity on the Cepheid Distance Scale. Part II: Theoretical Models and Synthetic Spectra

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Kayla Owens, , | Summary: This is the second of two papers exploring the effects of metallicity on the multi-wavelength properties of Cepheids in terms of their multi-wavelength period-luminosity (PL) relations, impacting their use as extragalactic distance indicators, underpinning one […]

CausalAbstain: Enhancing Multilingual LLMs with Causal Reasoning for Trustworthy Abstention

Kavli Affiliate: Wei Gao | First 5 Authors: Yuxi Sun, Aoqi Zuo, Wei Gao, Jing Ma, | Summary: Large Language Models (LLMs) often exhibit knowledge disparities across languages. Encouraging LLMs to textit{abstain} when faced with knowledge gaps is a promising strategy to reduce hallucinations in multilingual settings. Current abstention strategies for multilingual scenarios primarily rely […]

Millimeter-wave observations of Euclid Deep Field South using the South Pole Telescope: A data release of temperature maps and catalogs

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: M. Archipley, A. Hryciuk, L. E. Bleem, K. Kornoelje, M. Klein | Summary: Context. The South Pole Telescope third-generation camera (SPT-3G) has observed over 10,000 square degrees of sky at 95, 150, and 220 GHz (3.3, 2.0, 1.4 mm, respectively) overlapping the ongoing 14,000 square-degree Euclid Wide […]

Connecting JWST discovered N/O-enhanced galaxies to globular clusters: Evidence from chemical imprints

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Xihan Ji, Vasily Belokurov, Roberto Maiolino, Stephanie Monty, Yuki Isobe | Summary: Recent JWST observations have revealed a growing population of galaxies at $z>4$ with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to super-solar N/O at sub-solar O/H, clearly deviating from the well-established scaling relation […]

Ultra-diffuse galaxies in the EAGLE simulation

Haonan Zheng, Shihong Liao, Liang Gao, Fangzhou Jiang, | Summary: [[{“value”:”We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their properties closely match observations. The total masses of EAGLE UDGs range from ${sim}5times 10^{8}~M_{odot}$ to ${sim}2times 10^{11}~M_{odot}$, indicating that they are […]

Geometry of Kinematic Flow

Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Harry Goodhew, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We uncover a geometric organization of the differential equations for the wavefunction coefficients of conformally coupled scalars in power-law cosmologies. To do this, we introduce a basis of functions inspired by a decomposition of […]
