Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vasily Belokurov, Andrey Kravtsov, , , | Summary: We present a new scheme for the classification of the in-situ and accreted globular clusters (GCs). The scheme uses total energy $E$ and $z$-component of the orbital angular momentum and is calibrated using [Al/Fe] abundance ratio. We demonstrate that […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Angela V. Olinto, , , , | Summary: The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) was designed as a NASA Astrophysics probe-class mission to identify the sources of ultrahigh energy cosmic rays (UHECRs) and observe cosmic neutrinos from extremely energetic transient sources. POEMMA consists of two […]
Kavli Affiliate: Lindsey Bleem | First 5 Authors: Josemanuel Hernandez, Lindsey Bleem, Thomas Crawford, Nicholas Huang, Yuuki Omori | Summary: We explore the relationship between the thermal Sunyaev-Zel’dovich (tSZ) power spectrum amplitude and the halo mass and redshift of galaxy clusters in South Pole Telescope (SPT) data, in comparison with three $N$-body simulations combined with […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Tianlong Ma, Fengming Dong, Xian’an Jin, | Summary: For a k-tree T, a generalization of a tree, the local mean order of sub-k-trees of T is the average order of sub-k-trees of T containing a given k-clique. The problem whether the largest local mean order […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yuxiang Zhang, Zhuo Li, Jingze Lu, Hua Hua, Wenchao Wang | Summary: The current speech anti-spoofing countermeasures (CMs) show excellent performance on specific datasets. However, removing the silence of test speech through Voice Activity Detection (VAD) can severely degrade performance. In this paper, the impact of silence […]
Kavli Affiliate: Jia Liu | First 5 Authors: Lifeng Chen, Jia Liu, Yan Ke, Wenquan Sun, Weina Dong | Summary: A watermarking algorithm is proposed in this paper to address the copyright protection issue of implicit 3D models. The algorithm involves embedding watermarks into the images in the training set through an embedding network, and […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Yixiao Liu, Y. Sophia Dai, Stijn Wuyts, Jia-Sheng Huang, Linhua Jiang | Summary: We study 10 spectroscopically confirmed Ly$alpha$ emitters (LAEs) at $zapprox3.1$ in the UDS field, covered by JWST/NIRCam in the PRIMER program. All LAEs are detected in all NIRCam bands from F090W to F444W, corresponding […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Keisuke Inomata, Masahiro Kawasaki, Kyohei Mukaida, Tsutomu T. Yanagida, | Summary: The stochastic gravitational wave background (SGWB) recently detected by the PTA collaborations could be the gravitational waves (GWs) induced by curvature perturbations. However, primordial black holes (PBHs) might be overproduced if the SGWB is explained by […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, , , | Summary: Using an updated and significantly augmented sample of Cepheid and TRGB distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-point […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Jiří Svoboda, Michal Dovčiak, James F. Steiner, Fabio Muleri, Adam Ingram | Summary: X-ray polarization is a powerful tool to investigate the geometry of accreting material around black holes, allowing independent measurements of the black hole spin and orientation of the innermost parts of the accretion […]
