Simulating the galactic system in interaction AM 2229-735 and the formation of its polar structure
Luis F. Quiroga, Juan C. Muñoz-Cuartas, Irapuan Rodrigues +1
We study the formation of polar ring galaxies via minor mergers. We used N-body+hydrodynamics simulations to reproduce the dynamics of the observed system AM 2229-735 that is a min…
The Southern Photometric Local Universe Survey (S-PLUS): improved SEDs, morphologies and redshifts with 12 optical filters
C. Mendes de Oliveira, T. Ribeiro, W. Schoenell +142
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ~9300 deg^2 of the celestial sphere in twelve optical bands using a dedicated 0.8 m robotic telescope, the T80-So…
Misaligned snowplough effect and the electromagnetic counterpart to black hole binary mergers
Fabrícia A. C. Pereira, Giuseppe Lodato, Irapuan Rodrigues +2
We estimate the accretion rates produced when a circumprimary gas disc is pushed into the primary supermassive black hole (SMBH) by the tidal force of the decaying secondary during…
On the central abundances of Active Galactic Nuclei and Star-forming Galaxies
O. L. Dors, M. V. Cardaci, G. F. Hagele +5
We examine the relation between oxygen abundances in the narrow-line regions (NLRs) of active galactic nuclei (AGNs) estimated from the optical emission lines through the strong-li…
Interaction effects on galaxy pairs with Gemini/GMOS- II: Oxygen abundance gradients
D. A. Rosa, O. L. Dors, A. C. Krabbe +5
In this paper we derived oxygen abundance gradients from HII regions located in eleven galaxies in eight systems of close pairs. Long-slit spectra in the range 4400-7300A were obta…
Analysis of nuclear activity of ten polar ring galaxies
P. Freitas-Lemes, I. Rodrigues, O. L. Dors +1
The accumulation of mass from the interaction process that forms the polar ring galaxies is a factor that favors the conditions necessary to trigger nonthermal nuclear activities..…
