In the realm of energy journalism, it’s crucial to stay informed about scientific advancements that could potentially impact the industry. A recent study, led by researchers from the University of Portsmouth and the Lawrence Berkeley National Laboratory, among other institutions, has produced a set of mock catalogs for the Dark Energy Spectroscopic Instrument Peculiar Velocity Survey (DESI-PV) Data Release 1 (DR1). These mock catalogs are designed to replicate the characteristics of the Bright Galaxy Survey and the DESI PV samples, focusing on low redshift (z<0.1) and peculiar velocities derived from Fundamental plane and Tully-Fisher distances. The researchers, including J. Bautista, A. J. Amsellem, V. Aronica, and others from various institutions, have meticulously matched the properties of the mock catalogs to real data. They have also mimicked the measurement of distance indicators and peculiar velocities, ensuring that the statistical properties align with real-world observations. Additionally, the mock samples include type-Ia supernovae to complement the other distance indicators. The primary goal of this research is to measure the growth rate of structure, denoted as fσ8, using the DESI PV DR1. The mock catalogs allow for precise tests of clustering models and uncertainty estimation, providing an unprecedented level of accuracy. The consensus value for the DESI DR1 PV growth rate measurement is fσ8 = 0.450 ± 0.055. This set of mock catalogs represents the largest and most realistic for cosmological measurements with peculiar velocities to date. For the energy sector, understanding the growth rate of cosmic structures can have implications for large-scale energy projects, such as the placement of offshore wind farms or the routing of intercontinental power lines. Accurate models of cosmic structure can help in assessing the long-term stability and feasibility of such projects. Furthermore, the methods developed for this research can be applied to improve the accuracy of energy demand forecasting models, which rely on understanding and predicting large-scale human and economic activities.
