The TESS Mission Target Selection Procedure

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

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 […]

Do cooling and heating functions actually exist?

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 the gas as a function of its temperature and other physical properties. In a most general case they depend on the detailed distributions […]
