The Active Nucleus in NGC 4579
Roberto B. Menezes, João E. Steiner, Tiago V. Ricci +1
In this work, we present an analysis of a data cube obtained with the instrument IFU/GMOS Gemini North telescope centered on the nuclear region of the LINER galaxy NGC 4579. This g…
The nature of the LINER in the galaxy NGC 404
Roberto B. Menezes, João E. Steiner, Tiago V. Ricci +1
NGC 404, at a distance of 3.4 Mpc, is the nearest S0 galaxy. This galaxy harbors a LINER; however, since the spectrum does not show a broad Hα emission, it is not certain that this…
Optical identification of the transient supersoft X-ray source RX J0527.8-6954, in the LMC
A. S. Oliveira, J. E. Steiner, T. V. Ricci +2
Context. Close binary supersoft X-ray sources (CBSS) are binary systems that contain a white dwarf with stable nuclear burning on its surface. These sources, first discovered in th…
Stellar archeology of the nearby LINER galaxies NGC 4579 and NGC 4736
J. E. Steiner, R. B. Menezes, T. V. Ricci +1
Stellar archeology of nearby LINER galaxies may reveal if there is a stellar young population that may be responsible for the LINER phenomenon. We show results for the classical LI…
PCA Tomography and its application to nearby galactic nuclei
J. E. Steiner, R. B. Menezes, T. V. Ricci +1
With the development of modern technologies such as IFUs, it is possible to obtain data cubes in which one produces images with spectral resolution. To extract information from the…
The stellar populations of the AGN/Starburst galaxy NGC7582
T. V. Ricci, J. E. Steiner, R. B. Menezes +2
NGC 7582 is defined as a Starburst/AGN galaxy, since its optical and X-Ray spectra reveal both characteristics. In this work, we show the results of a stellar population modeling i…
