Semiresolved Stellar Populations as Distance Indicators
Ignacio Martín-Navarro, Patricia Iglesias Navarro, Francesco La Barbera +13
Galaxy distances are central to our understanding of the Universe. Despite the success of existing approaches, independent and complementary methods remain valuable for testing sys…
Baryonic properties of nearby galaxies across the stellar-to-total dynamical mass relation
Laura Scholz-Diaz, Ignacio Martin-Navarro, Jesus Falcon-Barroso +2
In the standard cosmological model, the assembly of galaxies is primarily driven by the growth of their host dark matter halos. At the center of these halos, however, baryonic proc…
Initial mass function variability from the integrated light of diverse stellar systems

We present spaxel-by-spaxel stellar population fits for the 10 thousand MaNGA datacubes. We provide multiple extension fits files, nominated as MEGACUBES, with maps of severa…
INSPIRE: INvestigating Stellar Population In RElics IV. The Initial Mass Function slope in relics
I. Martin-Navarro, C. Spiniello, C. Tortora +10
In the last decade, growing evidence has emerged supporting a non-universal stellar Initial Mass Function (IMF) in massive galaxies, with a larger number of dwarf stars with respec…
The dark side of galaxy stellar populations II: The dependence of star formation histories on halo mass and on the scatter of the main sequence
Laura Scholz-Diaz, Ignacio Martin-Navarro, Jesus Falcon-Barroso
Nearby galaxies are the end result of their cosmological evolution, which is predicted to be influenced by the growth of their host dark matter halos. This co-evolution potentially…
The survival of stellar discs in Fornax-like environments, from TNG50 to real galaxies
Pablo M. Galán-de Anta, M. Sarzi, A. Pillepich +14
We study the evolution of kinematically-defined stellar discs in 10 Fornax-like clusters identified in the TNG50 run from the IllustrisTNG suite of cosmological simulations. We con…
The Fornax3D project: Intrinsic Correlations between Orbital Properties and the Stellar Initial Mass Function
A. Poci, R. M. McDermid, M. Lyubenova +12
[arXiv Abridged] In this work, we explore new spatially-resolved measurements of the IMF for three edge-on lenticular galaxies in the Fornax cluster. Specifically, we utilise exist…
The Fornax3D project: The environmental impact on gas metallicity gradients in Fornax cluster galaxies
M. A. Lara-Lopez, P. M. Galan-de Anta, M. Sarzi +16
The role played by environment in galaxy evolution is a current debate in astronomy. The degree to which environment can alter, re-shape, or drive galaxy evolution is a topic of di…
The dark side of galaxy stellar populations I: The stellar-to-halo mass relation and the velocity dispersion - halo mass relation
Laura Scholz-Diaz, Ignacio Martin-Navarro, Jesus Falcon-Barroso
The growth and properties of galaxies are thought to be closely connected to the ones of their host dark matter halos. Despite the importance of this so-called galaxy-halo connecti…
The black hole population in low-mass galaxies in large-scale cosmological simulations
Houda Haidar, Melanie Habouzit, Marta Volonteri +8
Recent systematic searches for massive black holes (BHs) in local dwarf galaxies led to the discovery of a population of faint Active Galactic Nuclei (AGN). We investigate the agre…
Anisotropic satellite galaxy quenching modulated by supermassive black hole activity
Ignacio Martín-Navarro, Annalisa Pillepich, Dylan Nelson +4
The evolution of satellite galaxies is shaped by their constant interaction with the circum galactic medium surrounding central galaxies, which in turn may be affected by gas and e…
X-ray bubbles in the circumgalactic medium of TNG50 Milky Way- and M31-like galaxies: signposts of supermassive black hole activity
Annalisa Pillepich, Dylan Nelson, Nhut Truong +5
The TNG50 cosmological simulation produces X-ray emitting bubbles, shells, and cavities in the circumgalactic gas above and below the stellar disks of Milky Way- and Andromeda-like…
Diversity of nuclear star cluster formation mechanisms revealed by their star formation histories
K. Fahrion, M. Lyubenova, G. van de Ven +15
Nuclear star clusters (NSCs) are the densest stellar systems in the Universe and are found in the centres of all types of galaxies. They are thought to form via mergers of star clu…
The Fornax3D project: Assembly histories of lenticular galaxies from a combined dynamical and population orbital analysis

Galaxies within galaxies in the TIMER survey: stellar populations of inner bars are scaled replicas of main bars
Adrian Bittner, Adriana de Lorenzo-Cáceres, Dimitri A. Gadotti +11
Inner bars are frequent structures in the local Universe and thought to substantially influence the nuclear regions of disc galaxies. In this study we explore the structure and dyn…
