Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Fupeng Zhang, Xian Chen, Lijing Shao, Kohei Inayoshi, | Summary: We study the stellar binary black holes (BBHs) inspiralling/merging in galactic nuclei based on our numerical method GNC. We find that $3-40%$ of all new born BBHs will finally merge due to various dynamical effects. In a […]

Kavli Affiliate: Linhua Jiang | First 5 Authors: Jinyi Yang, Feige Wang, Xiaohui Fan, Aaron J. Barth, Joseph F. Hennawi | Summary: We report the results of near-infrared spectroscopic observations of 37 quasars in the redshift range $6.3< zle7.64$, including 32 quasars at $z>6.5$, forming the largest quasar near-infrared spectral sample at this redshift. The […]

Kavli Affiliate: Ran Wang | First 5 Authors: Yunjing Wu, Zheng Cai, Marcel Neeleman, Kristian Finlator, Shiwu Zhang | Summary: The physical and chemical properties of the circumgalactic medium (CGM) at $zgtrsim6$ have been studied successfully through the absorption in the spectra of background Quasi-Stellar Objects (QSOs). One of the most crucial questions is to […]

Kavli Affiliate: Subo Dong | First 5 Authors: E. Callis, M. Fraser, A. Pastorello, Subo Dong, S. J. Brennan | Summary: We present spectroscopy and photometry of SN 2018zd, a Type IIP core-collapse supernova with signatures of interaction with circumstantial material in its earliest spectra. High ionization lines, the earmark of shock breakout, are not […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Yong Gao, Xiao-Yu Lai, Lijing Shao, Ren-Xin Xu, | Summary: The strong interactions at low energy scales determine the state of the supranuclear matter in the pulsar-like compact objects. It is proposed that the bulk strong matter could be composed of strangeons, which are quark clusters with […]

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Saumya Gupta, Jessy Jose, Surhud More, Swagat R. Das, Gregory J. Herczeg | Summary: Low mass star formation inside massive clusters is crucial to understand the effect of cluster environment on processes like circumstellar disk evolution, planet and brown dwarf formation. The young massive association of […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Taiki Kawamuro, Claudio Ricci, Takuma Izumi, Masatoshi Imanishi, Shunsuke Baba | Summary: To investigate the role of active galactic nucleus (AGN) X-ray irradiation on the interstellar medium (ISM), we systematically analyzed Chandra and ALMA CO($J$=2-1) data for 26 ultra-hard X-ray ($>$ 10 keV) selected AGNs at redshifts […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Yi-Fan Wang, Stephanie M. Brown, Lijing Shao, Wen Zhao, | Summary: The routine detection of gravitational-wave events from compact binary coalescences has allowed precise tests of gravity in strong field, dynamical field, and high energy regime. In this work, we report the results of testing gravitational-wave birefringence […]

Kavli Affiliate: Jing Wang | First 5 Authors: Xiao-Yue Ren, Ya-Hui Zhai, Jing Wang, , | Summary: Quantum critical behaviors induced by a putative quantum phase transition are vigilantly investigated, which separates a $d$-wave superconducting state and $d$-wave superconducting+$X$ state below the superconducting dome of the $d-$wave superconductors with tuning the non-thermal doping variable. Within […]

Kavli Affiliate: Ke Wang | First 5 Authors: Efrat Shimron, Jonathan I. Tamir, Ke Wang, Michael Lustig, | Summary: While open databases are an important resource in the Deep Learning (DL) era, they are sometimes used "off-label": data published for one task are used for training algorithms for a different one. This work aims to […]
