Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Naoya Kitajima, Kai Murai, Shunsuke Neda | Summary: We study the clustering of primordial black holes (PBHs) and axion miniclusters produced in the model proposed to explain the LIGO/Virgo events or the seeds of the supermassive black holes (SMBHs) in arXiv:2006.13137. It is […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Jingze Lu, Zhenduo Zhao, Wenchao Wang, Pengyuan Zhang | Summary: Utilizing the large-scale unlabeled data from the target domain via pseudo-label clustering algorithms is an important approach for addressing domain adaptation problems in speaker verification tasks. In this paper, we propose a novel progressive subgraph […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhenduo Zhao, Zhuo Li, Wenchao Wang, Pengyuan Zhang | Summary: This report describes our submission to track1 and track3 for VoxCeleb Speaker Recognition Challenge 2022(VoxSRC2022). Our best system achieves minDCF 0.1397 and EER 2.414 in track1, minDCF 0.388 and EER 7.030 in track3. | Search Query: [#feed_custom_title] […]
Kavli Affiliate: Ran Wang | First 5 Authors: Xiaolong Yang, Su Yao, Luigi C. Gallo, Jun Yang, Luis C. Ho | Summary: Accretion of black holes at near-Eddington or super-Eddington rates is the most powerful episode that drives black hole growth, and it may work in several types of objects. However, the physics of accretion […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Roberto Maiolino, Jan Scholtz, Joris Witstok, Stefano Carniani, Francesco D’Eugenio | Summary: Black holes with masses in excess of several billion solar masses have been found at redshifts 6-7.5, when the universe was less than 1 Gyr old. The existence of such supermassive black holes already in […]
Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Daniele Rogantini, Stefano Bianchi, Matteo Guainazzi | Summary: Ultra-fast outflows (UFOs) have been revealed in a large number of active galactic nuclei (AGN) and are regarded as promising candidates for AGN feedback on the host galaxy. The nature and launching mechanism of UFOs […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S. Bennett, Debora Sijacki, Tiago Costa, Nicolas Laporte, Callum Witten | Summary: High-redshift quasars ($zgtrsim6$), powered by black holes (BHs) with large inferred masses, imply rapid BH growth in the early Universe. The most extreme examples have inferred masses of $sim ! 10^9,$M$_odot$ at $z = […]
Kavli Affiliate: Jiansheng Chen | First 5 Authors: Jingyuan Zhu, Huimin Ma, Jiansheng Chen, Jian Yuan | Summary: Realistic and diverse 3D shape generation is helpful for a wide variety of applications such as virtual reality, gaming, and animation. Modern generative models, such as GANs and diffusion models, learn from large-scale datasets and generate new […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Rainer Spurzem, Albrecht Kamlah | Summary: Dense star clusters are spectacular self-gravitating stellar systems in our Galaxy and across the Universe – in many respects. They populate disks and spheroids of galaxies as well as almost every galactic center. In massive elliptical galaxies nuclear clusters harbor supermassive […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Yihuan Di, Yuan Li, Feng Yuan, Fangzheng Shi, Mirielle Caradonna | Summary: We perform high-resolution hydrodynamical simulations using the framework of {it MACER} to investigate supermassive black hole (SMBH) feeding and feedback in a massive compact galaxy, which has a small effective radius but a large stellar […]
