FASTAR -- II. Semi-resolved evolutionary stellar population models
Ignacio Martín-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +12
Standard evolutionary synthesis models rely on the assumption of a fully sampled stellar initial mass function (IMF). Under this assumption, the age, chemical composition, and IMF…
FASTAR -- I. Continuous and differentiable evolutionary stellar population models
Ignacio Martín-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +11
The development of evolutionary stellar population models is central to interpreting observations of galaxies in terms of astrophysical quantities. Stellar population models must t…
Accelerated quenching and chemical enhancement of massive galaxies in a gas-rich halo
Pablo G. Pérez-González, Francesco D`Eugenio, Bruno Rodríguez del Pino +18
Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells whose mass is dominated by dark matter. Eventually, star formation quenches as gas is de…
INSPIRE: INvestigating Stellar Population In RElics VI -- The low-mass end slope of the stellar Initial Mass Function and chemical composition
Michalina Maksymowicz-Maciata, Chiara Spiniello, Ignacio Martín-Navarro +9
The INSPIRE project has built the largest sample of ultra-compact massive galaxies (UCMGs) at 0.1<z<0.4 and obtained their star formation histories (SFHs). Due to their preserved v…
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…
INSPIRE: INvestigating Stellar Population In RElics V. A catalogue of ultra-compact massive galaxies outside the local Universe and their degree of relicness
C. Spiniello, G. D'Ago, L. Coccato +18
This paper presents the third data release of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 52 ultra-compact massive galaxies (UCMGs) observed with t…
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…
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…
INSPIRE: INvestigating Stellar Population In RElics III. Second data release (DR2): testing the systematics on the stellar velocity dispersion
G. D'Ago, C. Spiniello, L. Coccato +15
This is the second data release (DR2) of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 21 new systems with observations completed before March 2022.…
A new method for age-dating the formation of bars in disc galaxies: The TIMER view on NGC1433's old bar and the inside-out growth of its nuclear disc
Camila de Sá-Freitas, Francesca Fragkoudi, Dimitri A. Gadotti +16
The epoch in which galactic discs settle is a major benchmark to test models of galaxy formation and evolution but is as yet largely unknown. Once discs settle and become self-grav…
Low-density star cluster formation: discovery of a young faint fuzzy on the outskirts of the low-mass spiral galaxy NGC 247
Aaron J. Romanowsky, Søren S. Larsen, Alexa Villaume +21
The classical globular clusters found in all galaxy types have half-light radii of 2-4 pc, which have been tied to formation in the dense cores of giant molecular…
The Fornax3D project: The assembly history of massive early-type galaxies in the Fornax cluster from deep imaging and integral field spectroscopy
M. Spavone, E. Iodice, G. D'Ago +16
This work is based on high quality integral-field spectroscopic data obtained with the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT). The 21 brightest…
Fornax 3D project: assessing the diversity of IMF and stellar population maps within the Fornax Cluster
I. Martín-Navarro, F. Pinna, L. Coccato +14
The stellar initial mass function (IMF) is central to our interpretation of astronomical observables and to our understanding of most baryonic processes within galaxies. The univer…
The Fornax3D project: Planetary nebulae catalogue and independent distance measurements to Fornax cluster galaxies
T. W. Spriggs, M. Sarz, P. M. Galán-de Anta +17
Extragalactic planetary nebulae (PNe) offer a way to determine the distance to their host galaxies thanks to the nearly universal shape of the planetary nebulae luminosity function…
The Fornax 3D project: PNe populations and stellar metallicity in edge-on galaxies
P. M. Galán-de Anta, M. Sarzi, T. W. Spriggs +17
Context. Extragalactic Planetary Nebulae (PNe) are useful distance indicators and are often used to trace the dark-matter content in external galaxies. At the same time, PNe can al…
The kinematics of young and old stellar populations in nuclear rings of MUSE TIMER galaxies
D. Rosado-Belza, J. Falcón-Barroso, J. H. Knapen +12
Studying the stellar kinematics of galaxies is a key tool in the reconstruction of their evolution. However, the current measurements of the stellar kinematics are complicated by s…
The Fornax 3D project: Non-linear colour-metallicity relation of globular clusters
K. Fahrion, M. Lyubenova, M. Hilker +15
Globular cluster (GC) systems of massive galaxies often show a bimodal colour distribution. This has been interpreted as a metallicity bimodality, created by a two-stage galaxy for…
The Fornax 3D project: Globular clusters tracing kinematics and metallicities
K. Fahrion, M. Lyubenova, M. Hilker +15
Globular clusters (GCs) are found ubiquitously in massive galaxies and due to their old ages, they are regarded as fossil records of galaxy evolution. Spectroscopic studies of GC s…
The Fornax 3D project: Thick disks in a cluster environment
F. Pinna, J. Falcón-Barroso, M. Martig +13
We used deep MUSE observations to perform a stellar-kinematic and population analysis of FCC 153 and FCC 177, two edge-on S0 galaxies in the Fornax cluster. The geometrical definit…
