Peta-electron volt gamma-ray emission from the Crab Nebula

Kavli Affiliate: Li Xin Li | First 5 Authors: The LHAASO Collaboration, Zhen Cao, F. Aharonian, Q. An, Axikegu | Summary: The Crab pulsar and the surrounding nebula powered by the pulsar’s rotational energy through the formation and termination of a relativistic electron-positron wind is a bright source of gamma-rays carrying crucial information about this […]

Video Text Tracking With a Spatio-Temporal Complementary Model

Kavli Affiliate: Jing Wang | First 5 Authors: Yuzhe Gao, Xing Li, Jiajian Zhang, Yu Zhou, Dian Jin | Summary: Text tracking is to track multiple texts in a video,and construct a trajectory for each text. Existing methodstackle this task by utilizing the tracking-by-detection frame-work, i.e., detecting the text instances in each frame andassociating the […]

KMT-2021-BLG-0912Lb: A microlensing super Earth around a K-type star

Kavli Affiliate: Subo Dong | First 5 Authors: Cheongho Han, Ian A. Bond, Jennifer C. Yee, Weicheng Zang, Michael D. Albrow | Summary: The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpose of identifying the origin of […]

OGLE-2019-BLG-0468Lb,c: two microlensing giant planets around a G-type star

Kavli Affiliate: Subo Dong | First 5 Authors: Cheongho Han, Andrzej Udalski, Chung-Uk Lee, Doeon Kim, Wei Zhu | Summary: With the aim of interpreting anomalous lensing events with no suggested models, we conducted a project of reinvestigating microlensing data in and before the 2019 season. In this work, we report a multi-planet system OGLE-2019-BLG-0468L […]

The Paschen Jump as a Diagnostic of the Diffuse Nebular Continuum Emission in Active Galactic Nuclei

Kavli Affiliate: Luis C. Ho | First 5 Authors: Hengxiao Guo, Aaron J. Barth, Kirk T. Korista, Michael R. Goad, Edward M. Cackett | Summary: Photoionization modeling of active galactic nuclei (AGN) predicts that diffuse continuum (DC) emission from the broad-line region makes a substantial contribution to the total continuum emission from ultraviolet through near-infrared […]

Moderate and $L^p$ maximal inequalities for diffusion processes and conformal martingales

Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Yong Chen, Mumien Cheng, Chen Jia, | Summary: The $L^p$ maximal inequalities for martingales are one of the classical results in the theory of stochastic processes. Here we establish the sharp moderate maximal inequalities for one-dimensional diffusion processes, which include the $L^p$ maximal inequalities as […]

Discovery of a protocluster core associated with an enormous Ly$α$ Nebula at $z = 2.3$

Kavli Affiliate: Ran Wang | First 5 Authors: Qiong Li, Ran Wang, Helmut Dannerbauer, Zheng Cai, Bjorn Emonts | Summary: The MAMMOTH-1 nebula at $z=2.317$ is an enormous Ly$alpha$ nebula (ELAN) extending to a $sim$440 kpc scale at the center of the extreme galaxy overdensity BOSS 1441. In this paper, we present observations of the […]

X-ray Simulations of Polar Gas in Accreting Supermassive Black Holes

Kavli Affiliate: Claudio Ricci | First 5 Authors: Jeffrey McKaig, Claudio Ricci, Stéphane Paltani, Shobita Satyapal, | Summary: Recent observations have shown that a large portion of the mid–infrared (MIR) spectrum of active galactic nuclei (AGN) stems from the polar regions. In this paper, we investigate the effects of this polar gas on the X-ray […]
