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

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

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 […]

Farpoint: A High-Resolution Cosmology Simulation at the Gigaparsec Scale

Kavli Affiliate: Salman Habib | First 5 Authors: Nicholas Frontiere, Katrin Heitmann, Esteban Rangel, Patricia Larsen, Adrian Pope | Summary: In this paper we introduce the Farpoint simulation, the latest member of the Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation family. The domain covers a volume of (1000$h^{-1}$Mpc)$^3$ and evolves close to two trillion particles, […]

$Λ$CDM: Much more than we expected, but now less than what we want

Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: The $rmLambda$CDM cosmological model is remarkable: with just 6 parameters it describes the evolution of the Universe from a very early time when all structures were quantum fluctuations on subatomic scales to the present, and it is consistent […]

Calibration of the MaGIXS experiment II: Flight Instrument Calibration

Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: P. S. Athiray, Amy R. Winebarger, Patrick Champey, Ken Kobayashi, Sabrina Savage | Summary: The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) is a sounding rocket experiment that observes the soft X-ray spectrum of the Sun from 6.0 – 24 Angstrom (0.5 – 2.0 keV), successfully launched […]

Can Cooling and Heating Functions be Modeled with Homogeneous Radiation Fields?

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: David Robinson, Camille Avestruz, Nickolay Y. Gnedin, , | Summary: Cooling and heating functions describe how radiative processes impact the thermal state of a gas as a function of its temperature and other physical properties. In a most general case the functions depend on the detailed […]

Geoneutrinos and geoscience: an intriguing joint-venture

Kavli Affiliate: Kunio Inoue | First 5 Authors: Gianpaolo Bellini, Kunio Inoue, Fabio Mantovani, Andrea Serafini, Virginia Strati | Summary: The review is conceived to help the reader to interpret present geoneutrino results in the framework of Earth’s energetics and composition. Starting from the comprehension of antineutrino production, propagation, and detection, the status of the […]
