Sleeping or Dead? Probing the Quenching Mechanism of JWST Dormant Galaxies at z > 3 with ALMA
Mengyuan Xiao, Songnan Qi, Pascal A. Oesch +16
JWST has revealed a population of "dormant'' galaxies at z>3 with strong Balmer breaks and weak emission lines, whose star formation appears to have declined only recently. Whether…
Barren but not Empty: The Impact of Void Environments on Galaxy and Halo Populations
Anita M. Schiller, Benjamin A. Seidel, Rhea-Silvia Remus +2
The combination of gravitational collapse and an accelerating expansion of the Universe drive an increasing fraction of volume toward becoming low-density voids across cosmic time.…
Non-spherical Cows: Introducing the Asphericity Parameter as a Measure of Accretion Geometry
Benjamin A. Seidel, Rhea-Silvia Remus, Lucas C. Kimmig +2
The outer regions of galactic halos represent the bridge connecting internal processes within the galaxy to the larger surrounding cosmic web. The gas in this bridge region is shap…
Built to Rest: The Evolving Star-Forming Main Sequence Requires Episodic Quiescence or Late Assembly
Lucas C. Kimmig, Jesse van de Sande, Rhea-Silvia Remus +3
The star-forming main sequence of galaxies has now been observed out to redshifts of and beyond. However, it remains unclear how long typical galaxies remain on or near it…
How Mergers and Flybys Shape Azimuthal Age Patterns in Spiral Galaxies
Qian-Hui Chen, Alex M. Garcia, Zefeng Li +7
Spiral structures are one of the most common features in galaxies, yet their origins and evolution remain debated. Stellar age distributions offer crucial insights into galaxy evol…
The influence of external environment at cosmic noon on the subsequent evolution of galaxy stellar mass
Tianmu Gao, J. Trevor Mendel, Lucas C. Kimmig +4
Connecting high-redshift galaxies to their low-redshift descendants is one of the most important and challenging tasks of galaxy evolution studies. In this work, we investigate whe…
Investigating the imprints of tidal features on simulated galaxy outskirts in LSST-like mock observations
Aman Khalid, Sarah Brough, Garreth Martin +5
Tidal features provide signatures of recent galaxy mergers, offering insights into the role of mergers in galaxy evolution. The Vera C. Rubin Observatory's upcoming Legacy Survey o…
Analysis of Galaxies at the Extremes: Failed Galaxy Progenitors in the MAGNETICUM Simulations
Jonah S. Gannon, Lucas C. Kimmig, Duncan A. Forbes +5
There is increasing observational evidence for a failed galaxy formation pathway for some ultradiffuse galaxies (UDGs) at low redshift however they currently lack simulated counter…
Living the stream: Properties and progenitors of tidal shells and streams around galaxies from Magneticum
Johannes Stoiber, Lucas M. Valenzuela, Rhea-Silvia Remus +4
Stellar shells and streams are remnants of satellite galaxies visible around galaxies. Advances in low-surface-brightness observations and increasing resolution of cosmological sim…
Tidal features around simulated groups and cluster galaxies: Enhancement and suppression of merger events through environment in LSST-like mock observations
Aman Khalid, Sarah Brough, Garreth Martin +5
Generally, merger likelihood increases in denser environments; however, the large relative velocities at the centres of dense clusters are expected to reduce the likelihood of merg…
Witnessing downsizing in the making: quiescent and breathing galaxies at the dawn of the Universe
Emiliano Merlin, Flaminia Fortuni, Antonello Calabrò +18
[Shortened for arXiv] We conduct a systematic search for quiescent galaxies at in six extragalactic deep fields observed with NIRCam, with t…
A massive and evolved slow-rotating galaxy in the early Universe
Ben Forrest, Adam Muzzin, Danilo Marchesini +15
In the contemporary Universe, most galaxies are supported by ordered rotation, yet a significant subset of the most massive and quiescent systems are dominated by random stellar mo…
The Impact of Cluster Mergers on Galaxy Properties
Oğuzhan Çakır, Matt S. Owers, Lucas C. Kimmig +4
The impact of galaxy cluster mergers on the properties of the resident galaxies remains poorly understood. In this paper, we investigate the effects of merging environments on star…
On the unique evolutionary mechanisms of massive quiescent galaxies in the epoch of reionisation
Harry George Chittenden, Karl Glazebrook, Themiya Nanayakkara +4
We investigate the evolutionary histories of a population of high mass, high redshift, quiescent galaxies in the cosmohydrodynamical simulation Thesan, studying the characteristic…
Intra-Cluster Light as a Dynamical Clock for Galaxy Clusters: Insights from the MAGNETICUM, IllustrisTNG, Hydrangea and Horizon-AGN Simulations
Lucas C. Kimmig, Sarah Brough, Klaus Dolag +19
As the most massive nodes of the cosmic web, galaxy clusters represent the best probes of structure formation. Over time, they grow by accreting and disrupting satellite galaxies,…
Die Hard: The On-Off-Cycle of Galaxies on the Star Formation Main Sequence
Silvio Fortuné, Rhea-Silvia Remus, Lucas C. Kimmig +2
Our picture of galaxy evolution currently assumes that galaxies spend their life on the star formation main sequence (SFMS) until they are eventually quenched. However, recent obse…
The MAGPI Survey: the subtle role of environment and not-so-subtle impact of generations of stars on galaxy dynamics
Caroline Foster, Sabine Bellstedt, Francesco DEugenio +23
The stellar age and mass of galaxies have been suggested as the primary determinants for the dynamical state of galaxies, with environment seemingly playing no or only a very minor…
From Particles to Pixels: How many particles do I really need to construct stellar kinematic mock observational measurements?
K. E. Harborne, C. del P. Lagos, S. M. Croom +5
This work considers the impact of resolution in the construction of mock observations of simulated galaxies. In particular, when building mock integral field spectroscopic observat…
