Kavli Affiliate: Linhua Jiang | First 5 Authors: Shu Wang, Linhua Jiang, Yue Shen, Luis C. Ho, Marianne Vestergaard | Summary: Broad line regions (BLRs) in high-redshift quasars provide crucial information of chemical enrichment in the early universe. Here we present a study of BLR metallicities in 33 quasars at redshift $5.7<z<6.4$. Using the near-IR […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: Joanna M. Piotrowska, Asa F. L. Bluck, Roberto Maiolino, Yingjie Peng, | Summary: In this paper we investigate how massive central galaxies cease their star formation by comparing theoretical predictions from cosmological simulations: EAGLE, Illustris and IllustrisTNG with observations of the local Universe from the Sloan Digital […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth, Markus Schöller, Silva Järvinen | Summary: We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star exhibited variations consistent with stars known to […]
Kavli Affiliate: Seth Digel | Summary:The sky at MeV energies is currently poorly explored. Here we present an innovative mission concept that builds on and improves past and currently proposed missions at such energies. We outline the motivations for combining a coded mask and a Compton telescope and we define the scientific goals of such […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Elena Orlando, Eugenio Bottacini, Alexander Moiseev, Arash Bodaghee, Werner Collmar | Summary: The sky at MeV energies is currently poorly explored. Here we present an innovative mission concept and we outline the scientific motivation for combining a coded mask and a Compton telescope. The Galactic Explorer with […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, , , , | Summary: Capturing long-range dependency and modeling long temporal contexts is proven to benefit speaker verification tasks. In this paper, we propose the combination of the Hierarchical-Split block(HS-block) and the Depthwise Separable Self-Attention(DSSA) module to capture richer multi-range context speaker features from […]
Kavli Affiliate: Jing Wang | First 5 Authors: Kai Liu, Keke Bai, Jing Wang, Juntao Song, Ying Liu | Summary: Antimonene is a novel two-dimensional topological semiconductor material with strain driven tunable electronic structure for future electronic and spintronic devices, but the growth of clean antimonene is not fully understood. In this work, the growth […]
