Simulating Atmospheric Characteristics and Daytime Astronomical Seeing Using Weather Research and Forecasting Model

Applied Sciences, 2023
The present study is aimed at the development of a novel empirical base for application to ground-based astronomical telescopes. A Weather Research and Forecasting (WRF) model is used for description of atmospheric flow structure with a high spatial ...

Bridging astronomical, astrometric and geodetic scheduling for VGOS

Journal of Geodesy, 2023
Very Long Baseline Interferometry (VLBI) experiments are organized within the geodetic, astrometric and astronomical communities for different applications, requiring different observation strategies adopted in scheduling.

Using EAGLE simulations to study the effect of observational constraints on the determination of H I asymmetries in galaxies [PDF]

, 2022
We investigate the effect of observational constraints such as signal-to-noise (S/N) ratio, resolution, and column density level on the H I morphological asymmetry (Amod) and the effect of noise on the H I global profile (Aflux) asymmetry indices.

The Rarity of Very Red Trans-Neptunian Objects in the Scattered Disk [PDF]

, 2021
We investigate the origins of the photometrically very red (VR) and less red (LR) trans-Neptunian objects (TNOs). We first reanalyze the data set of Marsset et al.

Supermassive black holes in cosmological simulations I: MBH − M⋆ relation and black hole mass function [PDF]

Monthly notices of the Royal Astronomical Society, 2020
The past decade has seen significant progress in understanding galaxy formation and evolution using large-scale cosmological simulations. While these simulations produce galaxies in overall good agreement with observations, they employ different sub ...

Modes of Pangean lake level cyclicity driven by astronomical climate pacing modulated by continental position and pCO2

Proceedings of the National Academy of Sciences of the United States of America, 2022
Siginificance The glacial cycles of the last 3 My demonstrate the fundamental control of astronomical variations on Earth’s climate system. Sedimentary records of orbital climate cycles from much further in Earth’s past provide insights into its behavior
