Comparing phylogenetic trees of stars with spectral graph distances
Theosamuele Signor, Matias Neto, Paula Jofré +9
Phylogenetic trees offer a hierarchical representation of chemical similarities among stars, from which their evolutionary histories can, in principle, be reconstructed. Simulation…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Cosmology with Tully-Fisher HI Galaxy Surveys
Joël Mayor, Anthony Carr, Khaled Said +7
The SKA Observatory will enable measurements of the Tully-Fisher relation for statistical samples of HI selected galaxies out to unprecedented depths and redshifts thanks to its un…
HI Simulations for Cosmology with the SKA Observatory
Tommaso Ronconi, Gabriella De Lucia, Marta Spinelli +15
We present a comparative overview of state-of-the-art methods for modelling the distribution of neutral hydrogen (HI) in the post-reionization Universe, developed in preparation fo…
Disentangling chemical evolution histories with phylogenetic trees
Rebeca Canales, Paula Jofré, Claudia Aguilera-Gómez +6
Chemical abundances encode the fossil record of galaxy evolution in a complex and diverse way that requires innovative approaches to reconstruct galactic histories. We investigate…
First Light and Reionization Epoch Simulations (FLARES) XXII: UV-dust spatial offsets at the Epoch of Reionisation
Paurush Punyasheel, Aswin P. Vijayan, William J. Roper +8
Recent observations have revealed intriguing offsets between the UV and FIR emission in high redshift galaxies. In this study, we use the First Light And Reionisation Epoch Simulat…
Reconstructing chemical enrichment pathways in disc galaxies: A phylogenetic approach
Brian Tapia-Contreras, Patricia B. Tissera, Emanuel Sillero +11
Phylogenetic methods, traditionally used in biology to trace the evolutionary relationships among species, are emerging as a powerful framework to reconstruct evolutionary processe…
Simulations of the 21cm emission line for upcoming large-scale HI galaxy surveys
Joël Mayor, Marta Spinelli, Gabriella De Lucia +5
Upcoming galaxy surveys with the SKA Observatory will detect neutral hydrogen (HI) across unprecedented volumes, and their scientific return will crucially depend on predictive mod…
EDGE-INFERNO: How chemical enrichment assumptions impact the individual stars of a simulated ultra-faint dwarf galaxy
Eric P. Andersson, Martin P. Rey, Robert M. Yates +6
The chemical abundances of stars in galaxies are a fossil record of the star formation and stellar evolution processes that regulate galaxy formation, including the stellar initial…
The emergence of globular clusters and globular-cluster-like dwarfs
Ethan D. Taylor, Justin I. Read, Matthew D. A. Orkney +7
Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery. Here we present a suite of cosmological simulations i…
The Connection between Dusty Star-Forming Galaxies and the First Massive Quenched Galaxies
Pablo Araya-Araya, Rachel K. Cochrane, Laerte Sodré +6
High-redshift (z > 2) massive quiescent (MQ) galaxies provide an opportunity to probe the key physical processes driving the fuelling and quenching of star formation in the early U…
Simultaneously Modelling Dusty Star Forming Galaxies and Massive Quiescents: A Calibration Framework for Galaxy Formation Models
Pablo Araya-Araya, Rachel K. Cochrane, Christopher C. Hayward +4
Galaxy formation models, particularly semi-analytic models (SAMs), rely on differential equations with free parameters to describe the physical mechanisms governing galaxy formatio…
Massive Star Clusters in the Semi-Analytical Galaxy Formation Model L-Galaxies 2020
Nils Hoyer, Silvia Bonoli, Nate Bastian +7
It is established that there exists a direct link between the formation history of star cluster populations and their host galaxies. However, our lack of understanding of the assem…
EDGE: The emergence of dwarf galaxy scaling relations from cosmological radiation-hydrodynamics simulations
Martin P. Rey, Ethan Taylor, Emily I. Gray +14
We present a new suite of EDGE (`Engineering Dwarfs at Galaxy formation's Edge') cosmological zoom simulations. The suite includes 15 radiation-hydrodynamical dwarf galaxies coveri…
EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies
Emily I. Gray, Justin I. Read, Ethan Taylor +8
Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to 4…
The Observed Relation between Stellar Mass, Dust Extinction and Star Formation Rate in Local Galaxies
H. Jabran Zahid, Robert M. Yates, Lisa J. Kewley +1
In this study we investigate the relation between stellar mass, dust extinction and star formation rate (SFR) using ~150,000 star-forming galaxies from the SDSS DR7. We show that t…
