Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
Cool Gas in the Circumgalactic Medium of Massive Post Starburst Galaxies
Zoe Harvey, Sahyadri Krishna, Vivienne Wild +2
Observing the interplay between galaxies and their gaseous surroundings is crucial for understanding how galaxies form and evolve, including the roles of long-lived cool gas reserv…
Optimised neural network predictions of galaxy formation histories using semi-stochastic corrections
Jayashree Behera, Rita Tojeiro, Harry George Chittenden
We present a novel methodology to improve predictions of galaxy formation histories by incorporating semi-stochastic corrections to account for short-timescale variability. Our pap…
Evaluating the galaxy formation histories predicted by a neural network in pure dark matter simulations
Harry George Chittenden, Jayashree Behera, Rita Tojeiro
We investigate a series of galaxy properties computed using the merger trees and environmental histories from dark matter only cosmological simulations, using a semi-recurrent neur…
Large Scale Structure and the Cosmic Web
Rita Tojeiro, Katarina Kraljic
The formation and evolution of galaxies cannot be separated from large scale structure growth. Dark matter halos (and, therefore, galaxies) form and grow within the cosmic web - th…
