LYRA: The formation and growth of nuclear star clusters in dwarf galaxies

Nuclear star clusters (NSCs) are among the densest stellar systems in the Universe and often coexist with supermassive black holes (SMBHs) at galaxy centres. While SMBH formation h…
Cosmic Threads: Interlinking the Stellar Initial Mass Function from Star-Birth to Galaxies
Tereza Jerabkova, Donatella Romano, Pavel Kroupa +19
The stellar initial mass function (sIMF) describes the distribution of stellar masses formed in a single star formation event in a molecular cloud clump. It is fundamental to astro…
Exploring the central region of NGC 1365 in the ultraviolet domain
Kshama Sara Kurian, C. S. Stalin, Dominika Wylezalek +6
Active galactic nuclei (AGN) feedback and its impact on their host galaxies are critical to our understanding of galaxy evolution. Here, we present a combined analysis of new high…
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…
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…
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…
The Fornax3D project: Environmental effects on the assembly of dynamically cold disks in Fornax cluster galaxies
Y. Ding, L. Zhu, G. van de Ven +12
We apply a population-orbit superposition method to 16 galaxies in the Fornax cluster observed with MUSE/VLT in the context of the Fornax3D project. By fitting the luminosity distr…
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…
Nuclear star cluster formation in star-forming dwarf galaxies
Katja Fahrion, Teodora-Elena Bulichi, Michael Hilker +7
Nuclear star clusters (NSCs) are massive star clusters found in all types of galaxies from dwarfs to massive galaxies. Recent studies show that while low-mass NSCs in dwarf galaxie…

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…
