Synchronized Co-evolution between Supermassive Black Holes and Galaxies Over the Last Seven Billion Years as Revealed by the Hyper Suprime-Cam

Posted by klaurent Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Junyao Li, John D. Silverman, Xuheng Ding, Michael A. Strauss, Andy Goulding | Summary: We measure the evolution of the $M_{rm BH}-M_*$ relation using 584 uniformly-selected SDSS quasars at $0.2<z<0.8$. The black-hole masses ($M_{rm BH}$) are derived from the single-epoch virial mass estimator using the H$beta$ […]

The TESS Mission Target Selection Procedure

Posted by klaurent MIT

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Michael Fausnaugh, Ed Morgan, Roland Vanderspek, Joshua Pepper, Christopher J. Burke | Summary: We describe the target selection procedure by which stars are selected for 2-minute and 20-second observations by TESS. We first list the technical requirements of the TESS instrument and ground systems processing that […]

The extreme properties of the nearby hyper-Eddington accreting Active Galactic Nucleus in IRAS 04416+1215

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Alessia Tortosa, Claudio Ricci, Francesco Tombesi, Luis C. Ho, Pu Du | Summary: The physical properties of the accretion flow and of the X-ray emitting plasma, in supermassive black holes accreting at extreme Eddington rates, are still very unclear. Here we present the analysis of simultaneous XMM-Newton […]

Height-Dependent LoS Probability Model for A2G MmWave Communications under Built-up Scenarios

Posted by klaurent Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Minghui Pang, Qiuming Zhu, Fei Bai, Zhuo Li, Hanpeng Li | Summary: Based on the three-dimensional propagation characteristic under built-up scenarios, a height-dependent line-of-sight (LoS) probability model for air-to-ground (A2G) millimeter wave (mmWave) communications is proposed in this paper. With comprehensive considerations of scenario factors, i.e., building […]
