Revisiting the role of bars in AGN fuelling with propensity score sample matching
Luiz A. Silva-Lima, Lucimara P. Martins, Paula R. T. Coelho +1
The high luminosity displayed by an active galactic nucleus (AGN) requires that gas be transported to the centre of the galaxy by some mechanism. Bar-driven processes are often poi…
Modelling simple stellar populations in the near-ultraviolet to near-infrared with the X-shooter Spectral Library (XSL)
Kristiina Verro, S. C. Trager, R. F. Peletier +12
We present simple stellar population models based on the empirical X-shooter Spectral Library (XSL) from NUV to NIR wavelengths. The unmatched characteristics of relatively high re…
Spectroscopic study of the HII regions in the NGC 1232 galaxy
Fabiana Lima-Costa, Lucimara P. Martins, Alberto Rodríguez-Ardila +1
NGC 1232 is a face-on spiral galaxy that serves as an excellent laboratory for the study of star formation due to its proximity. Recent studies have revealed interesting features a…
Optical/NIR stellar absorption and emission-line indices from luminous infrared galaxies
Rogério Riffel, Alberto Rodríguez-Ardila, Michael S. Brotherton +11
We analyze a set of optical-to-near-infrared long-slit nuclear spectra of 16 infrared-luminous spiral galaxies. All of the studied sources present H emission, which reflects th…
A close look at the dwarf AGN of NGC 4395: optical and near-IR integral field spectroscopy
Carine Brum, Marlon R. Diniz, Rogemar A. Riffel +7
Intermediate mass black holes (10-10 M) in the center of dwarf galaxies are believed to be analogous to growing Active Galactic Nuclei (AGN) in the early Universe.…
Star Formation Rate Distribution in the Galaxy NGC 1232
Alexandre Araújo de Souza, Lucimara P. Martins, Alberto Rodríguez-Ardila +1
NGC 1232 is a face-on spiral galaxy and a great laboratory for the study of star-formation due to its proximity. We obtained high spatial resolution Hα images of this galaxy, with…
