Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Claudio Ricci, Sophie M. Venselaar, Chin-Shin Chang, Mai Liao | Summary: The origin of compact millimeter (mm) continuum emission from radio-quiet AGNs (RQAGNs) is still not fully understood. Changing-state AGNs (CSAGNs) display rapid and strong variability, which can allow us to investigate the origin of […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Zexin Hu, Yong Gao, Lijing Shao, , | Summary: Neutron stars (NSs) are excellent laboratories for testing gravity theories as they are strongly self-gravitating bodies and have rich observational phenomena. However, strong-gravity effects in NS could be degenerate with their equation of state (EOS) which is largely […]
Kavli Affiliate: Jing Wang | First 5 Authors: Joel Jang, Seonghyeon Ye, Zongyu Lin, Jiannan Xiang, Johan Bjorck | Summary: We introduce DreamGen, a simple yet highly effective 4-stage pipeline for training robot policies that generalize across behaviors and environments through neural trajectories – synthetic robot data generated from video world models. DreamGen leverages state-of-the-art […]
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 […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Frank Wilczek, , , | Summary: We demonstrate that the statistical fluctuations in resonant radiation detectors operating in homodyne and heterodyne modes offers additional, complementary information to that obtained from their direct operation as click detectors. We use this to refine tests of the […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Frank Wilczek, , , | Summary: Gravitational radiation from known astrophysical sources is conventionally treated classically. This treatment corresponds, implicitly, to the hypothesis that a particular class of quantum-mechanical states — the so-called coherent states — adequately describe the gravitational radiation field. We propose […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Riku Ishikawa, Hitoshi Murayama, Shota Saito, , | Summary: We classify “truly confining” (t-confining) supersymmetric gauge theories, in which no center charges can be screened, and Wilson loops in the fundamental representation are therefore expected to exhibit an area law. In all cases, we identify the condensation […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer, Andrea Weibel, Yijia Li | Summary: JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, $z>10$, where few such sources were expected. Here we present the most distant example of this class yet — […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Kosuke Aizawa, Ryosuke Akizawa, Scott Cray, Shaul Hanany, Shotaro Kawano | Summary: We present designs and fabrication of sub-wavelength anti-reflection (AR) structures on alumina for infrared absorptive filters with passbands near 30, 125, and 250 GHz. These bands are widely used by ground-based instruments measuring the cosmic […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Yizhou Liu, Jeff Gore, Max Tegmark, | Summary: Beyond neural scaling laws, little is known about the laws underlying large language models (LLMs). We introduce Neural Thermodynamic Laws (NTL) — a new framework that offers fresh insights into LLM training dynamics. On the theoretical side, […]
