The universal variability of the stellar initial mass function probed by the TIMER survey
Ignacio Martín-Navarro, Adriana de Lorenzo-Cáceres, Dimitri A. Gadotti +7
The debate about the universality of the stellar initial mass function (IMF) revolves around two competing lines of evidence. While measurements in the Milky Way, an archetypal spi…

We present a study on the star formation histories (SFHs) of galaxies covering the range < M/M < , leveraging full spectral fitting algorithms…
Total mass slopes and enclosed mass constrained by globular cluster system dynamics
Tadeja Veršič, Sabine Thater, Glenn van de Ven +4
The goal of this work is to probe the total mass distribution of early-type galaxies with globular clusters (GCs) as kinematic tracers, by constraining the parameters of the profil…
The distribution of stellar orbits in Eagle galaxies -- the effect of mergers, gas accretion, and secular evolution
Giulia Santucci, Claudia Del P. Lagos, Katherine E. Harborne +9
The merger history of a galaxy is thought to be one of the major factors determining its internal dynamics, with galaxies having undergone different types or mergers (e.g. dry, min…
Quantifying the stellar ages of dynamically separated bulges and disks of CALIFA spiral galaxies
Yunpeng Jin, Ling Zhu, Stefano Zibetti +3
We employ a recently developed population-orbit superposition technique to simultaneously fit the stellar kinematic and age maps of 82 CALIFA spiral galaxies and obtain the ages of…
Schwarzschild Modeling of Barred S0 Galaxy NGC 4371
Behzad Tahmasebzadeh, Ling Zhu, Juntai Shen +15
We apply the barred Schwarzschild method developed by Tahmasebzadeh et al. (2022) to a barred S0 galaxy, NGC 4371, observed by IFU instruments from the TIMER and ATLAS3D projects.…
Expanding on the Fundamental Metallicity Relation in Dwarf Galaxies with MUSE
Teodora-Elena Bulichi, Katja Fahrion, François Mernier +10
The mass-metallicity relation (MZR) represents one of the most important scaling relations in the context of galaxy evolution, comprising a positive correlation between stellar mas…
Dark Matter Fraction in Disk-Like Galaxies Over the Past 10 Gyr
G. Sharma, G. van de Ven, P. Salucci +1
We present an observational study of the dark matter fraction in star-forming disk-like galaxies up to redshift , selected from publicly available integral field spectr…
oMEGACat I: MUSE spectroscopy of 300,000 stars within the half-light radius of Centauri
M. S. Nitschai, N. Neumayer, C. Clontz +17
Omega Centauri ( Cen) is the most massive globular cluster of the Milky Way and has been the focus of many studies that reveal the complexity of its stellar populations and kine…
On the accretion of a new group of galaxies onto Virgo: III. The stellar population radial gradients of dEs
Bahar Bidaran, Francesco La Barbera, Anna Pasquali +6
Using MUSE data, we investigate the radial gradients of stellar population properties (namely age, [M/H], and the abundance ratio of elements [/Fe]) for a sample of nine dwa…
Disc galaxies are still settling: The discovery of the smallest nuclear discs and their young stellar bars
Camila de Sá-Freitas, Dimitri A. Gadotti, Francesca Fragkoudi +11
When galactic discs settle and become massive enough, they are able to form stellar bars. These non-axisymmetric structures induce shocks in the gas, causing it to flow to the cent…
Stellar Half-Mass Radii of Galaxies: Comparison with JWST/NIRCam Half-Light Radii
Arjen van der Wel, Marco Martorano, Boris Haussler +12
We use CEERS JWST/NIRCam imaging to measure rest-frame near-IR light profiles of 500 galaxies in the redshift range . We compare the resulti…
ReveaLLAGN 0: First Look at JWST MIRI data of Sombrero and NGC 1052
K. Goold, A. Seth, M. Molina +28
We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGN. We focus on two observations with th…
Composite Bulges -- IV. Detecting Signatures of Gas Inflows in the IFU data: The MUSE View of Ionized Gas Kinematics in NGC 1097
Tutku Kolcu, Witold Maciejewski, Dimitri A. Gadotti +8
Using VLT/MUSE integral-field spectroscopic data for the barred spiral galaxy NGC 1097, we explore techniques that can be used to search for extended coherent shocks that can drive…
The flattening of dark matter halo of Centaurus A galaxy (NGC 5128) out to 40 kpc
Tadeja Veršič, Marina Rejkuba, Magda Arnaboldi +4
Cosmological simulations predict dark matter shapes that deviate from spherical symmetry. The exact shape depends on the prescription of the simulation and the interplay between da…
Dynamical modelling of ATLAS galaxies
Sabine Thater, Prashin Jethwa, Edward J. Lilley +3
Triaxial dynamical models of massive galaxies observed in the ATLAS3D project can provide new insights into the complex evolutionary processes that shape galaxies. The ATLAS3D surv…
NGC 1436: the making of a lenticular galaxy in the Fornax cluster
Alessandro Loni, Paolo Serra, Marc Sarzi +25
We study the evolutionary path of the Fornax cluster galaxy NGC1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts a…
Effect of the initial mass function on the dynamical SMBH mass estimate in the nucleated early-type galaxy FCC 47
Sabine Thater, Mariya Lyubenova, Katja Fahrion +4
Supermassive black holes (SMBHs) and nuclear star clusters (NSCs) co-exist in many galaxies. While the formation history of the black hole is essentially lost, NSCs preserve their…
