Different paths, same appearance: an intermediate-age red nugget at z~0.13
F. La Barbera, F. Buitrago, I. Ferreras +1
Massive ultra-compact galaxies are commonly regarded as nearby relics of the compact quiescent population at z~2-3, and detailed studies have focused so far only on old systems in…
Emergent Denoising of SDSS Galaxy Spectra Through Unsupervised Deep Learning
Oliver Camilleri, Zahra Sharbaf, Ignacio Ferreras
Spectroscopy represents the ideal observational method to maximally extract information from galaxies regarding their star formation and chemical enrichment histories. However, abs…
Reconciling concentration to virial mass relations
Dominik Leier, Ignacio Ferreras, Andrea Negri +1
The concentration-virial mass (c-M) relation is a fundamental scaling relation within the standard cold dark matter (CDM) framework well established in numerical simulations. Ho…
The elemental abundances of quiescent galaxies in the LEGA-C survey: the (non-)evolution of [α/Fe] from z = 0.75 to z = 0
Davide Bevacqua, Paolo Saracco, Francesco La Barbera +6
We measure the [/Fe] abundances for 183 quiescent galaxies at z = 0.60 - 0.75 with stellar masses ranging 10.4 \leq log10 10.4 log10 (M /M) 11.6 select…
The co-evolution of strong AGN and central galaxies in different environments
V. M. Sampaio, A. Aragón-Salamanca, M. R. Merrifield +3
We exploit a sample of 80,000 SDSS central galaxies to investigate the effect of AGN feedback on their evolution. We trace the demographics of optically-selected AGN (Seyferts) as…
On the bright-end of the UV luminosity functions of galaxies at
M. Sharma, M. J. Page, I. Ferreras +1
We derive the Ultra-Violet (UV) luminosity function (LF) of star-forming galaxies in the redshift range , in the rest-frame far-UV ( Å) wavelength. For this wo…
