SMARTY: The mileS Moderate resolution neAr-infRared sTellar librarY
Michele Bertoldo-Coêlho, Rogério Riffel, Marina Trevisan +13
Most of the observed galaxies cannot be resolved into individual stars and are studied through their integrated spectrum using simple stellar populations (SSPs) models, with stella…
Compact groups of dwarf galaxies in TNG50: late hierarchical assembly and delayed stellar build-up in the low-mass regime
Rodrigo Flores-Freitas, Marina Trevisan, Maitê Mückler +3
Compact groups of dwarf galaxies (CGDs) have been observed at low redshifts () and are direct evidence of hierarchical assembly at low masses. To understand the formation of…
The Origin of Massive Compact Galaxies: Lessons from IllustrisTNG
F. S. Lohmann, A. Schnorr-Müller, M. Trevisan +2
We investigate the formation and evolution of z=0 massive compact galaxies (MCGs) in the IllustrisTNG cosmological simulation. We found that, as in observations, MCGs are mainly ol…
Digging deeper into NGC\,6868 I: stellar population
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +8
We use Gemini integral field unit observations to map the stellar population properties in the inner region ( pc) of the galaxy NGC 6868. In order to understa…
High-resolution abundance analysis of red giants in the globular cluster NGC 6522
B. Barbuy, C. Chiappini, E. Cantelli +11
The [Sr/Ba] and [Y/Ba] scatter observed in some galactic halo stars that are very metal-poor stars and in a few individual stars of the oldest known Milky Way globular cluster NGC…
Deep Chandra Observations of HCG 16 - I. Active Nuclei, Star formation and Galactic Winds
E. O'Sullivan, A. Zezas, J. M. Vrtilek +6
We present new, deep Chandra X-ray and Giant Metrewave Radio Telescope 610~MHz observations of the spiral-galaxy-rich compact group HCG 16, which we use to examine nuclear activity…
