Indications of the invalidity of the exponentiality of the disk within bulges of spiral galaxies
Iris Breda, Polychronis Papaderos, Jean Michel Gomes
(abridged) A fundamental subject in Extragalactic Astronomy concerns the formation and evolution of late-type galaxies (LTGs). The standard scenario comprises the early assembly of…
Stellar age gradients and inside-out star formation quenching in galaxy bulges
Iris Breda, Polychronis Papaderos, Jean Michel Gomes +6
Radial age gradients hold the cumulative record of the multitude of physical processes driving the build-up of stellar populations and the ensuing star formation (SF) quenching pro…
Structural analysis of massive galaxies using HST deep imaging at z < 0.5
Sandra N. dos Reis, Fernando Buitrago, Polychronis Papaderos +11
Taking advantage of HST CANDELS data, we analyze the lowest redshift (z<0.5) massive galaxies in order to disentangle their structural constituents and study possible faint non-axi…
A new fitting concept for the robust determination of Sérsic model parameters
Iris Breda, Polychronis Papaderos, Jean Michel Gomes +1
The Sérsic law (SL) offers a versatile functional form for the structural characterization of galaxies near and far. Whereas applying it to galaxies with a genuine SL luminosity di…
The continuous rise of bulges out of galactic disks
I. Breda, P. Papaderos
(abridged) This study revolves around dmB, a new distance- and extinction-independent measure of the contribution by stellar populations older than 9 Gyr to the mean r-band surface…
