The MAGPI Survey: forward modelled gas-phase metallicity gradients in galaxies at
Yifan Mai, Scott M. Croom, Emily Wisnioski +19
We measure the seeing-deconvolved gas-phase metallicity gradients of 70 star-forming galaxies at from the MAGPI survey and investigate their relationship with galaxy pr…
The GECKOS Survey: Resolved, multiphase observations of mass-loading and gas density in the galactic wind of NGC 4666
Barbara Mazzilli Ciraulo, D. B. Fisher, R. Elliott +24
We present a multiphase, resolved study of the galactic wind extending from the nearby starburst galaxy NGC 4666. For this we use VLT/MUSE observations from the GECKOS program and…
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…
A Census of Double-Peaked Lyman-alpha Emitters in MAGPI: Classification, Global Characteristics, and Spatially Resolved Properties
Tamal Mukherjee, Tayyaba Zafar, Themiya Nanayakkara +17
Double-peaked Ly profiles provide critical insights into gas kinematics and the distribution of neutral hydrogen (HI) from the interstellar to the intergalactic medium (ISM to I…
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…
Towards Precision Cosmology With Improved PNLF Distances Using VLT-MUSE. III. Impact of Stellar Populations in Early-Type Galaxy
Azlizan A. Soemitro, Lucas M. Valenzuela, Martin M. Roth +5
Distance measurements using the planetary nebula luminosity function (PNLF) rely on the bright-end power-law cut-off magnitude (), which is defined by a number of the [OIII]$\…
The GECKOS survey: Jeans anisotropic models of edge-on discs uncover the impact of dust and kinematic structures
T. H. Rutherford, A. Fraser-McKelvie, E. Emsellem +17
The central regions of disc galaxies host a rich variety of stellar structures: nuclear discs, bars, bulges, and boxy-peanut (BP) bulges. These components are often difficult to di…
The PICS Project: II. Circumnebular extinction variations and their effect on the planetary nebula luminosity function
Lucas M. Valenzuela, George H. Jacoby, Rhea-Silvia Remus +2
For decades, the theoretical understanding of planetary nebulae (PNe) has remained in tension with the observed universal bright-end cutoff of the PN luminosity function (PNLF). Th…
Encyclopedia Magneticum: Scaling Relations from Cosmic Dawn to Present Day
Klaus Dolag, Rhea-Silvia Remus, Lucas M. Valenzuela +10
Galaxy and halo scaling relations, connecting a broad range of parameters, are well established from observations. The origin of many of these relations and their scatter is still…
Go with the Flow: The Self-Similar and Non-Linear Behaviour of Large-Scale In- and Outflows and the Impact of Accretion Shocks from Galaxies to Galaxy Clusters
Benjamin A. Seidel, Rhea-Silvia Remus, Lucas M. Valenzuela +2
From the scale-free nature of gravity, the structure in the universe is expected to be self-similar on large scales. However, this self-similarity will eventually break down due to…
The MAGPI Survey: the kinematic morphology-density relation (or lack thereof) and the Hubble sequence at
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 (), in the Middle-Ag…
A new class of dark matter-free dwarf galaxies? I. Clues from FCC 224, NGC 1052-DF2 and NGC 1052-DF4
Maria Luisa Buzzo, Duncan A. Forbes, Aaron J. Romanowsky +8
The discovery of quiescent, dark matter (DM)-deficient ultra-diffuse galaxies (UDGs) with overluminous globular clusters (GCs) has challenged galaxy formation models within the Lam…
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…
The PICS Project. I. The impact of metallicity and helium abundance on the bright end of the planetary nebula luminosity function
Lucas M. Valenzuela, Marcelo M. Miller Bertolami, Rhea-Silvia Remus +1
Planetary nebulae (PNe) and their luminosity function (PNLF) in galaxies have been used as a cosmic distance indicator for decades, yet a fundamental understanding is still lacking…
