Analysis of spatially resolved stellar populations and emission line properties in nearby galaxies with J-PLUS data. II-Results for the M51 group and first comparison with the M101 group

J. Thainá-Batista, R. Cid Fernandes, R. M. González Delgado +19

We characterize the spatially resolved stellar population and emission-line properties of galaxies in the M51 group using the same methodology previously applied to the M101 group,…

Probing the origin of the kilonova candidate GRB 230307A: analysis of host galaxy and offset

Clecio R. Bom, Davi C. Rodrigues, Arianna Cortesi +12

We investigate the host galaxy of the long gamma-ray burst GRB 230307A, which is associated with a kilonova candidate likely produced by a binary neutron-star (BNS) merger. The tra…

Investigating the clumpy star formation in an interacting dwarf irregular galaxy

Augusto E. Lassen, Ana L. Chies-Santos, Rogerio Riffel +9

Clumpy morphologies are more frequent in distant and low-mass star-forming galaxies. Therefore the less numerous nearby galaxies presenting kpc-sized clumps represent unique labora…

Spatially-resolved gas-phase metallicity in Seyfert galaxies

Mark Armah, Rogério Riffel, L. G. Dahmer-Hahn +7

We explore the relations between the gas-phase metallicity radial profiles (few hundred inner parsec) and multiple galaxy properties for 15 Seyfert galaxies from the AGNIFS (Active…

Digging deeper into NGC 6868 II: ionized gas and excitation mechanism

João P. V. Benedetti, Rogério Riffel, Tiago Ricci +9

We studied the ionized gas in the inner region ( pc) of the galaxy NGC 6868 using Gemini/GMOS integral field unit observations. Channel maps reveal complex ki…

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…
