Kavli Affiliate: Bo Gu | First 5 Authors: Songhan Zhao, Songhan Zhao, , , | Summary: In this paper, we consider a semantic-aware reconfigurable intelligent surface (RIS)-assisted wireless network, where multiple semantic users (SUs) simultaneously transmit semantic information to an access point (AP) by using the non-orthogonal multiple access (NOMA) method. The SUs can reshape […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Alexander C. Ogren, Alexander C. Ogren, , , | Summary: Wave propagation on the surface of a material contains information about physical properties beneath its surface. We propose a method for inferring the thickness and stiffness of a structure from just a video of waves on its […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ayantika Sengupta, Ayantika Sengupta, , , | Summary: Compact, scalable, and multiplexed fluorescence lifetime sensors are of great interest for point-of-care diagnostics. However, current solutions either lack broad-range wavelength-tuning capabilities or involve complex optical setups that hinder miniaturization. On-chip entangled photon sources offer a promising alternative […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: , , , , | Summary: Massive galaxy clusters act as prominent strong-lenses. Due to a combination of observational biases, cluster evolution and lensing efficiency, most of the known cluster lenses lie typically at $z_lsim0.2-0.7$, with only a few prominent examples at higher redshifts. Here we […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Matilde Brazzini, Matilde Brazzini, , , | Summary: The majority of Little Red Dots (LRDs) hosting Active Galactic Nuclei (AGN) exhibits broad H$alpha$ emission, which recent studies propose originates from scattering off free electrons within an ionized and dense medium embedding the Broad Line Region (BLR), rather […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Carmen Embil Villagra, Carmen Embil Villagra, , , | Summary: We measure the amplitude of matter fluctuations over a wide range of redshifts by combining CMB lensing observations from ACT DR6 and $textitPlanck$ PR4 with the overdensity of quasars from Quaia, a $textitGaia$ and $textitunWISE$ quasar catalog. […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: William McClymont, William McClymont, , , | Summary: We present an analysis of metallicities and chemical abundances at $3<z<12$ in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity relations (MZR) are already in place at $zapprox12$ and evolve slowly ($sim$0.2 dex increase for […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Jiyao Zhang, Jiyao Zhang, , , | Summary: Modern large language models (LLMs) show promising progress in formalizing informal mathematics into machine-verifiable theorems. However, these methods still face bottlenecks due to the limited quantity and quality of multilingual parallel corpora. In this paper, we propose a novel […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Melissa Pesce-Rollins, , , | Summary: We report on the $gamma$-ray emission above 100~MeV from the GOES M3.3 flare SOL2012-06-03. The hard X-ray (HXR) and microwave emissions have typical time profiles with a fast rise to a well-defined peak followed by a slower decay. The […]
