Collimation and scattering of the active galactic nucleus emission in the Sombrero galaxy
R. B. Menezes, J. E. Steiner, T. V. Ricci
We present an analysis of a data cube of the central region of M104, the Sombrero galaxy, obtained with the GMOS-IFU of the Gemini-South telescope, and report the discovery of coll…
Discovery of an Halpha emitting disk around the supermassive black hole of M31
R. B. Menezes, J. E. Steiner, T. V. Ricci
Due to its proximity, the mass of the supermassive black hole in the nucleus of Andromeda galaxy (M31), the most massive black hole in the Local Group of galaxies, has been measure…
NGC 7097: the AGN and its mirror, revealed by PCA Tomography
T. V. Ricci, J. E. Steiner, R. B. Menezes
Three-dimensional (3D) spectroscopy techniques are becoming more and more popular, producing an increasing number of large data cubes. The challenge of extracting information from…
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…
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…
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…
