Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Zhuo Li, Pengcheng Ding, Cristina Mattioli, Wujun Huang | Summary: On-surface synthesis (OSS) involving relatively high energy barriers remains challenging due to a typical dilemma: firm molecular anchor is required to prevent molecular desorption upon the reaction, whereas sufficient lateral mobility is crucial for subsequent […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Vivek Kumar Jha, Ravi Joshi, Hum Chand, Xue-Bing Wu, Luis C. Ho | Summary: We present the accretion disk size estimates for a sample of 19 active galactic nuclei (AGN) using the optical $g$, $r$, and $i$ band light curves obtained from the Zwicky Transient Facility […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Alessia Tortosa, Claudio Ricci, Francesco Tombesi, Luis C. Ho, Pu Du | Summary: The physical properties of the accretion flow and of the X-ray emitting plasma, in supermassive black holes accreting at extreme Eddington rates, are still very unclear. Here we present the analysis of simultaneous XMM-Newton […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Minghui Pang, Qiuming Zhu, Fei Bai, Zhuo Li, Hanpeng Li | Summary: Based on the three-dimensional propagation characteristic under built-up scenarios, a height-dependent line-of-sight (LoS) probability model for air-to-ground (A2G) millimeter wave (mmWave) communications is proposed in this paper. With comprehensive considerations of scenario factors, i.e., building […]

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Yu-Peng Zhang, Yan-Bo Zeng, Yong-Qiang Wang, Shao-Wen Wei, Pau Amaro Seoane | Summary: Future space-borne gravitational-wave detectors will observe the gravitational waves in the milli-Hz. Extreme-mass-ratio inspirals with central supermassive black holes are very important sources that could provide the information of the vicinity of black […]

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem, Manuel Arca-Sedda, Mirek Giersz | Summary: We present direct N-body simulations, carried out with Nbody6++GPU, of young and compact low metallicity star clusters with $1.1times 10^5$ stars, a velocity dispersion of $sim$ 10 $mathrm{km,s^{-1}}$, a half mass radius $R_h=0.6$ pc, […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Chang Liu, Lijing Shao, , , | Summary: The detections of gravitational waves (GWs) from binary neutron star (BNS) systems and neutron star–black hole (NSBH) systems provide new insights into dense matter properties in extreme conditions and associated high-energy astrophysical processes. However, currently information about NS equation […]

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Laura Flagg, Christopher Johns-Krull, Kevin France, Gregory Herczeg, Joan Najita | Summary: Using HST-COS FUV spectra, we have discovered warm molecular hydrogen in the TWA 7 system. TWA 7, a $sim$9 Myr old M2.5 star, has a cold debris disk and has previously shown no signs of […]

Kavli Affiliate: Hu Zhan | First 5 Authors: Kai Xiao, Haibo Yuan, J. Varela, Hu Zhan, Jifeng Liu | Summary: Understanding the origins of small-scale flats of CCDs and their wavelength-dependent variations plays an important role in high-precision photometric, astrometric, and shape measurements of astronomical objects. Based on the unique flat data of 47 narrow-band […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Fan Hu, Zhuo Li, Donglian Xu, , | Summary: Cosmic neutrinos are unique probes of the high energy universe. IceCube has discovered a diffuse astrophysical neutrino flux since 2013, but their origin remains elusive. The potential sources could include, for example, active galactic nuclei, gamma-ray bursts and […]
