Galactic Morpholography: Linking present-day galaxy compactness to assembly history and relic formation in the COLIBRE simulations

Maximilian Zemsch, Claudia D. P. Lagos, Chiara Spiniello +11

Compactness is widely used to identify candidate relic galaxies, the largely untouched survivors of the first compact massive galaxies. Yet relicness is an evolutionary rather than…

Atomic hydrogen in $z = 0$ galaxies in the COLIBRE simulations

Kyle A. Oman, Ruby J. Wright, Andrea Gebek +12

We present an overview of the properties of atomic hydrogen (HI) in galaxies at redshift $z = 0$ in the COLIBRE cosmological galaxy formation simulations. COLIBRE directly simulates…

Quiescent Galaxies at $z > 2$ from CAPERS spectroscopy and their Number densities

Lu Shen, Weida Hu, Casey Papovich +28

Recent JWST observations have revealed an overabundance of quiescent galaxies at high redshift. Photometric methods, such as photometry-derived sSFRs, $U V J$ colors, and synthetic $…

OutThere Survey: Addressing $ξ_{ion}$ and $f_{esc}$ with a population of average galaxies at z $\sim$ 2

Ravi Jaiswar, Anshu Gupta, Elisabete da Cunha +24

Constraining the major contributors to the ionisation of the early universe is an ongoing endeavour of high-redshift galaxy research. We measure the ionising photon production effi…

The MAGPI survey: Stellar population radial trends and mass assembly in star-forming galaxies at z~0.3

Federica Mauro, Bodo Ziegler, Iris Breda +19

The evolution of galaxies from cosmic noon to the present day provides a key window to probe the balance between early, rapid bulge formation and prolonged disk growth. The epoch a…

Deep Extragalactic VIsible Legacy Survey (DEVILS): Morphologically-selected galaxy merger fractions and their direct comparison to close-pair samples

Melissa F. Fuentealba-Fuentes, Luke J. M. Davies, Aaron S. G. Robotham +4

Galaxy mergers are a central driver of galaxy evolution across cosmic time, and thus, quantifying their frequency is critical for constraining hierarchical models of galaxy formati…

The MAGPI Survey: forward modelled gas-phase metallicity gradients in galaxies at $z \sim 0.3$

Yifan Mai, Scott M. Croom, Emily Wisnioski +19

We measure the seeing-deconvolved gas-phase metallicity gradients of 70 star-forming galaxies at $z \sim 0.3$ from the MAGPI survey and investigate their relationship with galaxy pr…

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…

Connecting Environment, Star Formation History, and Morphology of Massive Quiescent Galaxies at $3 < z < 4$ with JWST

Lalitwadee Kawinwanichakij, Karl Glazebrook, Themiya Nanayakkara +9

We present the morphological properties of 17 spectroscopically confirmed massive quiescent galaxies ( $10.2 < lo g (M_{*} / M_{⊙}) < 11.2$ ) at $3.0 < z < 4.3$ , observed with JW…

Deep Extragalactic VIsible Legacy Survey (DEVILS): New robust merger rates at intermediate redshifts

Melissa F. Fuentealba-Fuentes, Luke J. M. Davies, Aaron S. G. Robotham +5

Mergers are fundamental to our understanding of the processes driving the evolution of the structure and morphology of galaxies, star formation, AGN activity, and the redistributio…

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…

The MAGPI Survey: the kinematic morphology-density relation (or lack thereof) and the Hubble sequence at $z \sim 0.3$

Caroline Foster, Mark W. Donoghoe, Andrew Battisti +26

This work presents visual morphological and dynamical classifications for 637 spatially resolved galaxies, most of which are at intermediate redshift ( $z \sim 0.3$ ), in the Middle-Ag…

The MAGPI Survey: radial trends in star formation across different cosmological simulations in comparison with observations at $z \sim$ 0.3

Marcie Mun, Emily Wisnioski, Katherine E. Harborne +20

We investigate the internal and external mechanisms that regulate and quench star formation (SF) in galaxies at $z \sim 0.3$ using MAGPI observations and the EAGLE, Magneticum, and…

The formation histories of massive and quiescent galaxies in the 3 < z < 4.5 Universe

Themiya Nanayakkara, Karl Glazebrook, Corentin Schreiber +16

We present the formation histories of 19 massive ( $> 3 X 1 0^{10} M_{⊙}$ ) quiescent (sSFR $< 0.15 G y r^{- 1}$ ) galaxy candidates at z~3.0-4.5 observed using JWST/NIRSpec. This completes th…

The MAGPI Survey: Massive slow rotator population in place by $z \sim 0.3$

Caro Derkenne, Richard M. McDermid, Francesco D'Eugenio +20

We use the `Middle Ages Galaxy Properties with Integral field spectroscopy' (MAGPI) survey to investigate whether galaxies have evolved in the distribution of their stellar angular…

Modelling the galaxy radio continuum from star formation and active galactic nuclei in the Shark semi-analytic model

Samuel P. Hansen, Claudia D. P. Lagos, Matteo Bonato +4

We present a model of radio continuum emission associated with star formation (SF) and active galactic nuclei (AGN) implemented in the Shark semi-analytic model of galaxy formation…

DEVILS/MIGHTEE/GAMA/DINGO: The Impact of SFR Timescales on the SFR-Radio Luminosity Correlation

Robin H. W. Cook, Luke J. M. Davies, Jonghwan Rhee +20

The tight relationship between infrared luminosity (L $_{TIR}$ ) and 1.4 GHz radio continuum luminosity (L $_{1.4GHz}$ ) has proven useful for understanding star formatio…
