ProGeny II: the impact of libraries and model configurations on inferred galaxy properties in SED fitting
Sabine Bellstedt, Aaron S. G. Robotham
We use a volume-complete sample of ~8,000 galaxies from the GAMA survey to characterise the impact of stellar population libraries (SPLs) and model configurations on the resulting…
ProGeny I: a new simple stellar population spectra generator and impact of isochrones / stellar atmospheres / initial mass functions
A. S. G. Robotham, S. Bellstedt
In this work we introduce ProGeny, a new stellar population library (SPL) software package written in R. This release encapsulates the core software (github.com/asgr/ProGeny) to ge…
The MAGPI Survey: the evolution and drivers of gas turbulence in intermediate-redshift galaxies
Yifan Mai, Scott M. Croom, Emily Wisnioski +21
We measure the ionised gas velocity dispersions of star-forming galaxies in the MAGPI survey () and compare them with galaxies in the SAMI () and KROSS ($z\sim…
The MAGPI Survey: Evidence Against the Bulge-Halo Conspiracy
C. Derkenne, R. M. McDermid, G. Santucci +14
Studies of the internal mass structure of galaxies have observed a `conspiracy' between the dark matter and stellar components, with total (stars dark) density profiles showing…
Unveiling the (in)consistencies among the galaxy stellar mass function, star formation histories, satellite abundances and intracluster light from a semi-empirical perspective
Hao Fu, Francesco Shankar, Mohammadreza Ayromlou +16
In a hierarchical, dark matter-dominated Universe, stellar mass functions (SMFs), galaxy merger rates, star formation histories (SFHs), satellite abundances, and intracluster light…
The MAGPI Survey: Massive slow rotator population in place by
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…
Wide Area VISTA Extra-galactic Survey (WAVES): Unsupervised star-galaxy separation on the WAVES-Wide photometric input catalogue using UMAP and
Todd L. Cook, Behnood Bandi, Sam Philipsborn +13
Star-galaxy separation is a crucial step in creating target catalogues for extragalactic spectroscopic surveys. A classifier biased towards inclusivity risks including spurious sta…
The MAGPI Survey: Using kinematic asymmetries in stars and gas to dissect drivers of galaxy dynamical evolution
R. S. Bagge, C. Foster, F. D'Eugenio +18
We present a study of kinematic asymmetries from the integral field spectroscopic surveys MAGPI and SAMI. By comparing the asymmetries in the ionsied gas and stars, we aim to disen…
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) and 1.4 GHz radio continuum luminosity (L) has proven useful for understanding star formatio…
The MAGPI Survey: Evolution of radial trends in star formation activity across cosmic time
Marcie Mun, Emily Wisnioski, Andrew J. Battisti +19
Using adaptive optics with the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT), the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI…
The Mass Density of MgII Absorbers from the Australian Dark Energy Survey
Asif Abbas, Christopher W. Churchill, Glenn G. Kacprzak +3
We present an all-southern sky survey for MgII doublet absorbers in 951 z < 4 AGN/quasar spectra from the Australian Dark Energy Survey (OzDES). The spectral resolution ranges from…
The LOFAR-eFEDS survey: The incidence of radio and X-ray AGN and the disk-jet connection
Z. Igo, A. Merloni, D. Hoang +15
Radio jets are present in a diverse sample of AGN. However, the mechanisms of jet powering are not fully understood, and it is yet unclear to what extent they obey mass-invariant s…
EMU/GAMA: A Technique for Detecting Active Galactic Nuclei in Low Mass Systems
Jahang Prathap, Andrew M. Hopkins, Aaron S. G. Robotham +17
We propose a new method for identifying active galactic nuclei (AGN) in low mass () galaxies. This method relies on spectral energy distribution (SED) fi…
