Stability of rotation axis of galactic disks in HESTIA suite
Naira R. Arakelyan, Sergey V. Pilipenko, Stefan Gottlöber +3
We have found that in approximately 1/4 of Milky Way or M31 analogues in the HESTIA suite of simulations there is a significant, , change in the axis of rotation orienta…
Enabling Cosmic Web Analysis at Gigaparsec Scales: A Multi Block Approach for DisPerSE
Ankit Singh, Frazer Pearce, Meghan Gray +1
Cosmic filaments are the longest structures in the Universe and the dominant element of the cosmic web, channelling matter onto clusters and shaping the environments in which galax…
Machine Learning the Dark Matter Halo Mass of the Milky Way
Elaheh Hayati, Peter Behroozi, Ekta Patel +3
Although numerous dynamical techniques have been developed to estimate the total dark matter halo mass of the Milky Way, it remains poorly constrained, with typical systematic unce…
The life and times of dark matter haloes: what will I be when I grow up?
Julian Onions, Frazer Pearce, Alexander Knebe +6
Are the most massive objects in the Universe today the direct descendants of the most massive objects at higher redshift? We address this question by tracing the evolutionary histo…
Line Intensity Mapping Prediction from the Cosmic Dawn (CoDa) III Simulation for H from Galaxies and the Intergalactic Medium during the Epoch of Reionization
Eugene Hyeonmin Lee, Joohyun Lee, Paul R. Shapiro +13
The evolution of large-scale structure, galaxies and the intergalactic medium (IGM) during the Epoch of Reionization (EoR) can be probed by upcoming Line Intensity Mapping (LIM) ex…
Variable gravitational potential of Milky Way analogues in HESTIA suite
Naira R. Arakelyan, Sergey V. Pilipenko, Stefan Gottlöber +3
Investigations of trajectories of various objects orbiting the Milky Way (MW) halo with modern precision, achievable in observations by Gaia, requires sophisticated, non-stationary…
Astraeus X: Indications of a top-heavy initial mass function in highly star-forming galaxies from JWST observations at z>10
Anne Hutter, Elie R Cueto, Pratika Dayal +3
The James Webb Space Telescope (JWST) has uncovered an abundance of galaxies bright in the ultraviolet (UV) that has challenged traditional theoretical models at high redshi…
Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation
Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13
Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…
The impact of an evolving stellar initial mass function on early galaxies and reionisation
Elie Rasmussen Cueto, Anne Hutter, Pratika Dayal +5
Observations with JWST have revealed an unexpected high abundance of bright z>10 galaxy candidates. We explore whether a stellar initial mass function (IMF) that becomes increasing…
Astraeus III: The environment and physical properties of reionization sources
Anne Hutter, Pratika Dayal, Laurent Legrand +2
In this work, we use the {\sc astraeus} (seminumerical rAdiative tranSfer coupling of galaxy formaTion and Reionization in N-body dArk mattEr simUlationS) framework which couples g…
