We characterized the kinematics, morphology, and stellar population (SP) properties of a sample of massive compact quiescent galaxies (MCGs, 10 log M /M 11 and re ∼ 1–3 kpc) in the MaNGA Survey, with the goal of constraining their formation, asse

Despite numerous efforts, it is still unclear whether lenticular galaxies (S0s) evolve from spirals whose star formation was suppressed, or formed trough mergers or disk instabilities. In this paper we present a pilot study of 21 S0 galaxies in extre

We map optical and near-infrared (NIR) stellar population properties of the inner 320 × 535 pc2 of the elliptical galaxy NGC 1052. The optical and NIR spectra were obtained using the Gemini Integral Field Units of the GMOS instrument and NIFS, respe

Recovering the origins of lenticular galaxies can shed light on the understanding of galaxy formation and evolution, since they present properties that can be found in both elliptical and spiral galaxies. In this work we study the kinematics of the g

In the hierarchical two-phase formation scenario, the extended halos of early type galaxies (ETGs) are expected to have different physical properties from those of the galaxies' central regions. This work aims at characterizing the kinematic properti

População estelar em galáxias ativas versus não ativas : o papel das novas gerações de estrelas

Autor: Raimann, Daniel Iunes

Publikováno v: Biblioteca Digital de Teses e Dissertações da UFRGSUniversidade Federal do Rio Grande do SulUFRGS.

Esta tese apresenta o estudo da população estelar nuclear e extranuclear de uma amostra de galáxias ativas próximas (trinta e sete galáxias Seyfert 2 e vinte e quatro rádio-galáxias); e de uma amostra de controle de galáxias não ativas (onze

We present BV RI CCD surface photometry for 4 elliptical and 2 S0 galaxies that show bright emission lines in their nuclear spectra. We obtained isophote maps, luminosity profiles, and basic photometric parameters. We also obtained continuum subtract
