Kavli Affiliate: Moritz Guenther | Summary:The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system and the full orbit is determined. The mass of the companion has been determined from an it IUE spectrum and comparison with the mass-temperature relation from Detached Eclipsing Binaries. Combined with the mass […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Ioannis Liodakis, Haocheng Zhang, Stella Boula, Riccardo Middei, Jorge Otero-Santos | Summary: The origin of the high-energy emission in astrophysical jets from black holes is a highly debated issue. This is particularly true for jets from supermassive black holes that are among the most powerful particle […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Zekai Li, Xinhao Zhong, Samir Khaki, Zhiyuan Liang, Yuhao Zhou | Summary: In recent years, dataset distillation has provided a reliable solution for data compression, where models trained on the resulting smaller synthetic datasets achieve performance comparable to those trained on the original datasets. To further improve […]
Kavli Affiliate: 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-field gravity effects in NS could be degenerate with their equation of state (EOS) which is largely unknown. Fortunately, there exist the so-called universal relations among the NS […]
Kavli Affiliate: Luis Ho | Summary:The early growth of high-redshift quasars and their host galaxies raises critical questions about their cosmic evolution. We exploit the angular resolution and sensitivity of NIRCam to investigate the host galaxies of 31 quasars at $4lesssim zlesssim7$ drawn from multiple JWST surveys. Using a new multi-band forward-modeling code (textscGalfitS) that […]
Kavli Affiliate: Gang Su | First 5 Authors: Xin-Wei Yi, Wei Li, Jing-Yang You, Bo Gu, Gang Su | Summary: Recent strain-stabilized superconductivity at ambient pressure in La$_3$Ni$_2$O$_{7}$ films opens new avenues for nickelates research, in parallel with its pressure-induced counterpart. Using density functional theory calculations, we elucidate the critical factors bridging strain- and pressure-driven […]

Kavli Affiliate: Irfan Siddiqi | Summary:The Josephson junction is the fundamental nonlinear building block of superconducting quantum technologies. Its macroscopic quantum tunneling physics underpins superconducting quantum computing, sensing, and communication, but scaling these platforms to utility-scale architectures places increasingly stringent demands on junction materials, interfaces, and fabrication. In quantum computing, these demands include high reproducibility, […]
Kavli Affiliate: Luis Ho | Summary:James Webb Space Telescope (JWST) has revealed a new class of high-redshift, very red, compact broad-line sources, termed as "little red dots" (LRDs). The physical mechanism driving these properties remains elusive. We construct spectral energy distributions (SEDs) with spectroscopic redshift for 28 LRDs and find they exhibit V-shaped SEDs with […]
