The evolution of the mass-metallicity relation in SDSS galaxies uncovered by astropaleontology
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We have obtained the mass-metallicity (M-Z) relation at different lookback times for the same set of galaxies from the Sloan Digital Sky Survey, using the stellar metallicities estimated with our spectral synthesis code ...
Unresolved versus resolved: testing the validity of young simple stellar population models with VLT/MUSE observations of NGC 3603
(EDP Sciences, 2016)
Context. Stellar populations are the building blocks of galaxies, including the Milky Way. The majority, if not all, extragalactic studies are entangled with the use of stellar population models given the unresolved nature ...
Shapley Supercluster Survey: ram-pressure stripping versus tidal interactions in the Shapley supercluster
(2016)
We present two new examples of galaxies undergoing transformation in the Shapley supercluster core. These low-mass galaxies are members of the two clusters SC 1329-313 and SC 1327-312 z similar to 0.049). Integral-field ...
An analysis of the composite stellar population in M32
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We obtained long-slit spectra of high signal-to-noise ratio of the galaxy M32 with the Gemini Multi-Object Spectrograph at the Gemini-North telescope. We analysed the integrated spectra by means of full spectral fitting ...
Velocity dispersion of brightest cluster galaxies in cosmological simulations
(Wiley Blackwell Publishing, Inc, 2021-11)
Using the DIANOGA hydrodynamical zoom-in simulation set of galaxy clusters, we analyse the dynamics traced by stars belonging to the brightest cluster galaxies (BCGs) and their surrounding diffuse component, forming the ...
Spatially resolved stellar population parameters in the BCGs of two fossil groups
(Oxford University PressOxford, 2014)
We report the results of Gemini/GMOS long-slit spectroscopic observations along the major
and minor axes of the central galaxies in two fossil groups, SDSS J073422.21+265133.9 and
SDSS J075828.11+374711.8 (the NGC 2484 ...
THE VVV SURVEY REVEALS CLASSICAL CEPHEIDS TRACING A YOUNG and THIN STELLAR DISK ACROSS the GALAXY'S BULGE
(Institute of Physics Publishing, 2015-10)
Solid insight into the physics of the inner Milky Way is key to understanding our Galaxy's evolution, but extreme dust obscuration has historically hindered efforts to map the area along the Galactic mid-plane. New ...
