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…
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…
AGN feedback in the Local Universe: multiphase outflow of the Seyfert galaxy NGC 5506
Federico Esposito, Almudena Alonso-Herrero, Santiago García-Burillo +21
We present new optical GTC/MEGARA seeing-limited (0.9") integral-field observations of NGC 5506, together with ALMA observations of the CO(3-2) transition at a 0.2" (25 pc) resolut…
The GW Vir instability strip in the light of new observations of PG 1159 stars. Discovery of pulsations in the central star of Abell 72 and variability of RX J0122.9-7521
Paulina Sowicka, Gerald Handler, David Jones +9
We present the results of new time series photometric observations of 29 pre-white dwarf stars of PG 1159 spectral type, carried out in the years 2014-2022. For the majority of sta…
A radio-jet driven outflow in the Seyfert 2 galaxy NGC 2110?
L. Peralta de Arriba, A. Alonso-Herrero, S. García-Burillo +16
We present a spatially-resolved study of the ionised gas in the central 2 kpc of the Seyfert 2 galaxy NGC 2110 and investigate the role of its moderate luminosity radio jet (kineti…
Relic galaxies: where are they?
Luis Peralta de Arriba, Vicent Quilis, Ignacio Trujillo +2
The finding that massive galaxies grow with cosmic time fired the starting gun for the search of objects which could have survived up to the present day without suffering substanti…
Massive relic galaxies prefer dense environments
Luis Peralta de Arriba, Vicent Quilis, Ignacio Trujillo +2
We study the preferred environments of massive relic galaxies ( galaxies with little or no growth from star formation or merger…
Constraints on the evolutionary mechanisms of massive galaxies since from their velocity dispersions
L. Peralta de Arriba, M. Balcells, I. Trujillo +9
Several authors have reported that the dynamical masses of massive compact galaxies (, ), computed a…
Which galaxy mass estimator can we trust?
Luis Peralta de Arriba, Marc Balcells, Jesús Falcón-Barroso +1
We address the problem that dynamical masses of high-redshift massive galaxies, derived using virial scaling, often come out lower than stellar masses inferred from population fitt…
The discrepancy between dynamical and stellar masses in massive compact galaxies traces non-homology
L. Peralta de Arriba, M. Balcells, J. Falcón-Barroso +1
For many massive compact galaxies, their dynamical masses () are lower than their stellar masses (). We analyse the unphysical mas…
