Mapping the Galactic disk with the LAMOST and $Gaia$ Red clump sample: V: On the origin of the “young” [$α$/Fe]-enhanced stars

Kavli Affiliate: Huawei Zhang | First 5 Authors: Weixiang Sun, Yang Huang, Haifeng Wang, Chun Wang, Meng Zhang | Summary: Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and $Gaia$ surveys, we have identified a large sample of "young" [$alpha$/Fe]-enhanced stars with stellar ages younger than 6.0 Gyr and […]

Intermediate Mass Black Hole Formation in compact Young Massive Star Clusters

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem, Mirek Giersz, J. P. Ostriker | Summary: Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with Nbody6++GPU of 10 […]

Merging of Unequal Mass Binary Black Holes in Non-Axisymmetric Galactic Nuclei

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Peter Berczik, Manuel Arca Sedda, Margaryta Sobolenko, Marina Ishchenko, Olexander Sobodar | Summary: In this work we study the stellar-dynamical hardening of unequal mass supermassive black hole (SMBH) binaries in the central regions of galactic nuclei. We present a comprehensive set of direct N-body simulations of the […]

Merging stellar and intermediate-mass black holes in dense clusters: implications for LIGO, LISA and the next generation of gravitational wave detectors

Kavli Affiliate: Xian Chen | First 5 Authors: Manuel Arca-Sedda, Pau Amaro-Seoane, Xian Chen, , | Summary: We study the formation of intermediate-mass ratio inspirals (IMRIs) triggered by the interactions between two stellar black holes (BHs) and an intermediate-mass BH (IMBH) inhabiting the centre of a dense star cluster. We exploit $N$-body models varying the […]

Planetary Systems in a Star Cluster II: intermediate-mass black holes and planetary systems

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Flammini Dotti, M. B. N. Kouwenhoven, Qi Shu, Wei Hao, Rainer Spurzem | Summary: Most stars form in dense stellar environments. It is speculated that some dense star clusters may host intermediate-mass black holes (IMBHs), which may have formed from runaway collisions between high-mass stars, or […]

On the survival of resonant and non-resonant planetary systems in star clusters

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Katja Stock, Maxwell X. Cai, Rainer Spurzem, M. B. N. Kouwenhoven, Simon Portegies Zwart | Summary: Despite the discovery of thousands of exoplanets in recent years, the number of known exoplanets in star clusters remains tiny. This may be a consequence of close stellar encounters perturbing the […]

Explainable Recommendation via Interpretable Feature Mapping and Evaluation of Explainability

Kavli Affiliate: Li Xin Li | First 5 Authors: Deng Pan, Xiangrui Li, Xin Li, Dongxiao Zhu, | Summary: Latent factor collaborative filtering (CF) has been a widely used technique for recommender system by learning the semantic representations of users and items. Recently, explainable recommendation has attracted much attention from research community. However, trade-off exists […]

Revealing the formation mechanism of the shell galaxy NGC474 with MUSE

Kavli Affiliate: Eric Peng | First 5 Authors: Jeremy Fensch, Pierre-Alain Duc, Sungsoon Lim, Éric Emsellem, Michal Bílek | Summary: Stellar shells around galaxies could provide precious insights into their assembly history. However, their formation mechanism remains poorly empirically constrained, in particular the type of galaxy collisions at their origin. We present MUSE@VLT data of […]

Robust and Accurate Authorship Attribution via Program Normalization

Kavli Affiliate: Ke Wang | First 5 Authors: Yizhen Wang, Mohannad Alhanahnah, Ke Wang, Mihai Christodorescu, Somesh Jha | Summary: Source code attribution approaches have achieved remarkable accuracy thanks to the rapid advances in deep learning. However, recent studies shed light on their vulnerability to adversarial attacks. In particular, they can be easily deceived by […]

Correlating surface energy with adsorption energy by means of intrinsic characteristics of substrates

Kavli Affiliate: Li Xin Li | First 5 Authors: Bo Li, Xin Li, Wang Gao, Qing Jiang, | Summary: Surface energy is fundamental in controlling surface properties and surface-driven processes like heterogeneous catalysis, as adsorption energy is. It is thus crucial to establish an effective scheme to determine surface energy and its relation with adsorption […]
