INSPIRE: INvestigating Stellar Population In RElics -- I. Survey presentation and pilot program
C. Spiniello, C. Tortora, G. D'Ago +12
Massive ETGs are thought to form through a two-phase process. At early times, an intense and fast starburst forms blue and disk-dominated galaxies. After quenching, the remaining s…
Discovery of two Einstein crosses from massive post--blue nugget galaxies at z>1 in KiDS
N. R. Napolitano, R. Li, C. Spiniello +18
We report the discovery of two Einstein Crosses (ECs) in the footprint of the Kilo-Degree Survey (KiDS): KIDS J232940-340922 and KIDS J122456+005048. Using integral field spectrosc…
The first detection of ultra-diffuse galaxies in the Hydra I cluster from VEGAS survey
E. Iodice, M. Cantiello, M. Hilker +13
In this paper we report on the discovery of 27 low-surface brightness galaxies, of which 12 are candidate ultra-diffuse galaxy (UDG) in the Hydra I cluster, based on deep observati…
Nature versus nurture: relic nature and environment of the most massive passive galaxies at
C. Tortora, N. R. Napolitano, M. Radovich +13
Relic galaxies are thought to be the progenitors of high-redshift red nuggets that for some reason missed the channels of size growth and evolved passively and undisturbed since th…
New high-quality strong lens candidates with deep learning in the Kilo Degree Survey
R. Li, N. R. Napolitano, C. Tortora +11
We report new high-quality galaxy scale strong lens candidates found in the Kilo Degree Survey data release 4 using Machine Learning. We have developed a new Convolutional Neural N…
Building the largest spectroscopic sample of ultra-compact massive galaxies with the Kilo Degree Survey
Diana Scognamiglio, Crescenzo Tortora, Marilena Spavone +14
Ultra-compact massive galaxies UCMGs, i.e. galaxies with stellar masses and effective radii kpc, are very rare systems, in partic…
