Kavli Affiliate: Salman Habib | First 5 Authors: Andrew Ferguson, Andrew Ferguson, , , | Summary: This community paper developed out of the NSF Workshop on the Future of Artificial Intelligence (AI) and the Mathematical and Physics Sciences (MPS), which was held in March 2025 with the goal of understanding how the MPS domains (Astronomy, […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Yoshiki Matsuoka, Yoshiki Matsuoka, , , | Summary: We present spectroscopic identification of 43 quasars and 11 candidate obscured quasars in the epoch of reionization (EoR) at $5.71 le z le 7.02$, along with 29 galaxies at similar redshifts. This is the 24th publication from the […]
Kavli Affiliate: Gregory Prigozhin | First 5 Authors: Abigail Y. Pan, Abigail Y. Pan, , , | Summary: The Advanced X-ray Imaging Satellite (AXIS) is one of two candidate mission concepts selected for Phase-A study for the new NASA Astrophysics Probe Explorer (APEX) mission class, with a planned launch in 2032. The X-ray camera for […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Ildar Khabibullin, Ildar Khabibullin, , , | Summary: Extended X-ray emission observed in the direction of several molecular clouds in the Central Molecular Zone (CMZ) of our Galaxy exhibits spectral and temporal properties consistent with the `X-ray echo’ scenario. It postulates that the observed signal is a […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: A. R. Khalife, A. R. Khalife, , , | Summary: We present the most up-to-date constraints on axion early dark energy (AEDE) from cosmic microwave background (CMB) and baryon acoustic oscillation (BAO) measurements. In particular, we assess the impact of data from ground-based CMB experiments, the South […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Xian Chen, Xian Chen, , , | Summary: Theoretical models predict that intermediate-mass black holes (IMBHs) exist in globular clusters (GCs), but observational evidence remains elusive. Millisecond pulsars (MSPs), which are abundant in GCs and have served as precise probes for gravitational waves (GWs), offer a unique […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Yi-Bao Zhang, Ping-Fan Yang, Heng-Dong Xi, | Summary: Investigations into the effects of polymers on small-scale statistics and flow patterns were conducted in a turbulent von Karman swirling (VKS) flow. We employed the tomographic particle image velocimetry (Tomo-PIV) technique to obtain full information on three-dimensional […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Matthew Chen, Joshua Engels, Max Tegmark, , | Summary: Sparse autoencoders (SAEs) decompose language model representations into a sparse set of linear latent vectors. Recent works have improved SAEs using language model gradients, but these techniques require many expensive backward passes during training and still cause a […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Jingxin Liu, Xiang Gao, Yisha Li, Xin Li, Haiyang Lu | Summary: In the context of a short video & live stream mixed recommendation scenario, the live stream recommendation system (RS) decides whether to allocate at most one live stream into the video feed for each […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We present measurements of the branching fractions of eight $overline B{}^0to D^{(*)+} K^- K^{(*)0}_{(S)}$, $B^{-}to D^{(*)0} K^- K^{(*)0}_{(S)}$ decay channels. The results are based on data from SuperKEKB electron-positron collisions at the $Upsilon(4S)$ resonance […]
