Kavli Affiliate: Hu Zhan | First 5 Authors: Hengjie Lin, Yan Gong, Xuelei Chen, Kwan Chuen Chan, Zuhui Fan | Summary: China Space Station Telescope (CSST) is a forthcoming powerful Stage IV space-based optical survey equipment. It is expected to explore a number of important cosmological problems in extremely high precision. In this work, we […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Denzal Martin, Alexander Fieguth, Nadav Priel, Gautam Venugopalan | Summary: Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the cooling of one librational degree of freedom for $sim 5~mu$m […]

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: William J. Fischer, Lynne A. Hillenbrand, Gregory J. Herczeg, Doug Johnstone, Ágnes Kóspál | Summary: Variable accretion in young stellar objects reveals itself photometrically and spectroscopically over a continuum of timescales and amplitudes. Most dramatic are the large outbursts (e.g., FU Ori, V1647 Ori, and EX […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Jiayu Li, Zhuo Li, Xiu Liu, Stanislav Maslovski, Sheng Shen | Summary: Metasurfaces, together with graphene plasmonics, have become prominent for the emissivity control in thermal engineering, both passively through changing the geometric parameters and packing density of the metasurfaces, and actively through graphene gating or doping. […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Liying Kang, Yusai Xue, , | Summary: For a simple graph $F$, let $mathrm{Ex}(n, F)$ and $mathrm{Ex_{sp}}(n,F)$ denote the set of graphs with the maximum number of edges and the set of graphs with the maximum spectral radius in an $n$-vertex graph without any copy […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Junyao Li, John D. Silverman, Takuma Izumi, Wanqiu He, Masayuki Akiyama | Summary: The correlation between the mass of supermassive black holes (SMBHs; $mathcal{M}_{rm BH}$) and their host galaxies ($mathcal{M}_star$) in the reionization epoch provides valuable constraints on how their growth are jointly assembled in the early […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Claudio Ricci, Sachindra Naik, Atsushi Tanimoto, Neeraj Kumari | Summary: We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May and August in 2015 (~ 130 ks in total). […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vicente Rodriguez-Gomez, Shy Genel, S. Michael Fall, Annalisa Pillepich, Marc Huertas-Company | Summary: We use the TNG100 simulation of the IllustrisTNG project to investigate the stellar specific angular momenta ($j_{ast}$) of $sim$12~000 central galaxies at $z=0$ in a full cosmological context, with stellar masses ($M_{ast}$) ranging from […]
