Chemical characterisation of the X-shooter Spectral Library (XSL): [Mg/Fe] and [Ca/Fe] abundances
Pablo Santos-Peral, Patricia Sánchez-Blázquez, Alexandre Vazdekis +1
The X-shooter Spectral Library (XSL) is a large empirical stellar library used as a benchmark for the development of stellar population models. The inclusion of -elements abunda…
Improving Star Cluster Age Estimates in PHANGS-HST Galaxies and the Impact on Cluster Demographics in NGC 628
Bradley C. Whitmore, Rupali Chandar, Janice C. Lee +29
A long-standing problem when deriving the physical properties of stellar populations is the degeneracy between age, reddening, and metallicity. When a single metallicity is used fo…
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…
PHANGS-JWST First Results: A combined HST and JWST analysis of the nuclear star cluster in NGC 628
Nils Hoyer, Francesca Pinna, Albrecht W. H. Kamlah +28
We combine archival HST and new JWST imaging data, covering the ultraviolet to mid-infrared regime, to morphologically analyze the nuclear star cluster (NSC) of NGC 628, a grand-de…
MEGADES: MEGARA Galaxy Discs Evolution Survey. Data Release I: central fields
M. Chamorro-Cazorla, A. Gil de Paz, A. Castillo-Morales +12
The main interest of the Science Team for the exploitation of the MEGARA instrument at the 10.4m Gran Telescopio Canarias (GTC hereafter) is devoted to the study of nearby galaxies…
Optical spectroscopic characterization of Fermi blazar candidates of uncertain type with TNG and DOT: First Results
Amanda Olmo-GarcÍa, Vaidehi S. Paliya, Nuria Álvarez Crespo +4
The classification of gamma-ray-detected blazar candidates of uncertain type (BCU) is a relevant problem in extragalactic gamma-ray astronomy. Here we report the optical spectrosco…
Linking stellar populations to HII regions across nearby galaxies: I. Constraining pre-supernova feedback from young clusters in NGC1672
A. T. Barnes, R. Chandar, K. Kreckel +32
One of the fundamental factors regulating the evolution of galaxies is stellar feedback. However, we still do not have strong observational constraints on the relative importance o…
The Two-Dimensional Metallicity Distribution and Mixing Scales of Nearby Galaxies
Thomas G. Williams, Kathryn Kreckel, Francesco Belfiore +25
Understanding the spatial distribution of metals within galaxies allows us to study the processes of chemical enrichment and mixing in the interstellar medium (ISM). In this work,…
Modelling simple stellar populations in the near-ultraviolet to near-infrared with the X-shooter Spectral Library (XSL)
Kristiina Verro, S. C. Trager, R. F. Peletier +12
We present simple stellar population models based on the empirical X-shooter Spectral Library (XSL) from NUV to NIR wavelengths. The unmatched characteristics of relatively high re…
