Classificação cinemática de AGNs: busca por feedback em galáxias do MaNGA

Abstract

Galaxies with active nuclei (AGN) have a central supermassive black hole (SMBH) that emits outflows and jets of radiation
and particles. In some cases, this SMBH interferes with the dynamics of the host galaxy, altering its star formation. Such
a phenomenon is called feedback. In this work, a sample of 62 galaxies present in Sandro B. Rembold et al. (2017) [1]
observed by MaNGA to determine which are likely to present a feedback process. To do this, we examine the velocity
fields of the stars and the Hα gas of each galaxy to check whether the rotation of both parameters is similar, since galaxies
that have different velocity fields are likely to be undergoing feedback processes. The classifications used in this work
are separated into three classes: regular pattern velocity field (CVPR), irregular pattern velocity field (CVPI) and counter-
rotating velocity field (CVCR). Each galaxy in the sample also has its nuclear and extranuclear regions classified into
seyfert, LINER, composite or star-forming region. This is done by analyzing the BPT diagram of each galaxy analyzed.
According to the aforementioned classifications, a study can be made of the proportion of each type of classification for
each type of AGN.
