Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: Shaping Galaxies and Their Stars with Stellar Population Gradients, IMF Variations and Environmental Drivers in Cluster Early-Type Galaxies
A. Vazdekis, P. Sánchez-Blázquez, A. Ferré-Mateu +23
This white paper highlights how stellar population gradients, chemical abundance patterns, stellar initial mass function (IMF) variations, and structural signatures in early-type g…
SPAN: A cross-platform Python GUI software for optical and near-infrared spectral analysis
Daniele Gasparri, Lorenzo Morelli, Umberto Battino +2
The increasing availability of high-quality optical and near-infrared spectroscopic data, as well as advances in modelling techniques, have greatly expanded the scientific potentia…
Parameters for > 300 million Gaia stars: Bayesian inference vs. machine learning
F. Anders, A. Khalatyan, A. B. A. Queiroz +2
The Gaia Data Release 3 (DR3), published in June 2022, delivers a diverse set of astrometric, photometric, and spectroscopic measurements for more than a billion stars. The wealth…
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…
Space Telescope and Optical Reverberation Mapping Project. XII. Broad-Line Region Modeling of NGC 5548
P. R. Williams, A. Pancoast, T. Treu +155
We present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The dataset includes photo…
Space Telescope and Optical Reverberation Mapping Project. IX. Velocity-Delay Maps for Broad Emission Lines in NGC 5548
Keith Horne, G. De Rosa, B. M. Peterson +155
We report velocity-delay maps for prominent broad emission lines, Ly_alpha, CIV, HeII and H_beta, in the spectrum of NGC5548. The emission-line responses inhabit the interior of a…
Dynamical structure of small bulges reveals their early formation in ΛCDM paradigm
Luca Costantin, Jairo Méndez-Abreu, Enrico M. Corsini +6
The Λ cold dark matter (ΛCDM) paradigm of galaxy formation predicts that dense spheroidal stellar structures invariably grow at early cosmic time. These primordial spheroids evolve…
The CALIFA view on stellar angular momentum across the Hubble sequence
J. Falcón-Barroso, G. van de Ven, M. Lyubenova +32
[Abridged] We present the apparent stellar angular momentum of 300 galaxies across the Hubble sequence, using integral-field spectroscopic data from the CALIFA survey. Adopting the…
Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum
G. A. Kriss, G. De Rosa, J. Ely +164
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…
Star-formation in CALIFA early-type galaxies. A matter of discs
J. Mendez-Abreu, S. F. Sanchez, A. de Lorenzo-Caceres
The star formation main sequence (SFMS) is a tight relation between the galaxy star formation rate (SFR) and its total stellar mass (). Early-type galaxies (ETGs) are ofte…
The GIST Pipeline: A Multi-Purpose Tool for the Analysis and Visualisation of (Integral-field) Spectroscopic Data
A. Bittner, J. Falcón-Barroso, B. Nedelchev +16
We present a convenient, all-in-one framework for the scientific analysis of fully reduced, (integral-field) spectroscopic data. The GIST pipeline (Galaxy IFU Spectroscopy Tool) is…
Spectro-photometric decomposition of galaxy structural components
J. Méndez-Abreu, S. F. Sánchez, A. de Lorenzo-Cáceres
Galaxies are complex systems made up of different structural components such as bulges, discs, and bars. Understanding galaxy evolution requires unveiling, independently, their his…
Clocking the assembly of double-barred galaxies with the MUSE TIMER project
A. de Lorenzo-Cáceres, P. Sánchez-Blázquez, J. Méndez-Abreu +11
The formation of two stellar bars within a galaxy has proved challenging for numerical studies. It is yet not clear whether the inner bar is born via a star formation process promo…
The intrinsic three-dimensional shape of galactic bars
J. Mendez-Abreu, L. Costantin, J. A. L. Aguerri +2
We present the first statistical study on the intrinsic three-dimensional (3D) shape of a sample of 83 galactic bars extracted from the CALIFA survey. We use the galaXYZ code to de…
Star formation in the local Universe from the CALIFA sample. II. Activation and quenching mechanisms in bulges, bars, and disks
C. Catalán-Torrecilla, A. Gil de Paz, A. Castillo-Morales +22
We estimate the current extinction-corrected H star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multi-…
Observational constraints to boxy/peanut bulge formation time
I. Perez, I. Martinez-Valpuesta, T. Ruiz-Lara +10
Boxy/peanut bulges are considered to be part of the same stellar structure as bars and both could be linked through the buckling instability. The Milky Way is our closest example.…
Arm and interarm abundance gradients in CALIFA spiral galaxies
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +23
Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with easily distinguishable c…
Observational hints for radial migration in disc galaxies from CALIFA
T. Ruiz-Lara, I. Pérez, E. Florido +22
Context: According to numerical simulations, stars are not always kept at their birth galactocentric distances but migrate. The importance of this radial migration in shaping galac…
