Resumo: In this work, it is presented an automatic tool (M51-Finder) to identify new M51- type galaxies, which are constituted by a main spiral galaxy and its companion, a galaxy with size at least 50% less than the main galaxy. The primary dataset is based on the catalogues of Arp & Madore (1987), Jokim?ki et al. (2008) and HyperLeda. The M51-Finder?s tool uses as its criteria to identify new M51-type galaxies, some of the ones established in the literature as well as the ones obtained in this Dissertation. The Method was applied for whole Southern Hemisphere for a sample approximately equal to one million of galaxies from HyperLeda database. It is obtained the identification of 53 new candidates of M51-type galaxies, which need further confirmation, for instance by spectroscopic observations. The relevance of this work can be highlighted comparing with the previous confirmed M51-type galaxies as well as its candidates which totalizes 232 and 435 M51-type galaxies, respectively.

O conjunto de dados utilizado teve como base os cat?logos de Arp & Madore (1987), Jokim?ki et al. (2008) e HyperLeda. O M51-Finder utiliza alguns crit?rios estabelecidos na literatura para identificar Sistemas do Tipo-M51, assim como outros pr?prios derivados na Disserta??o. O M?todo foi aplicado para todo o Hemisf?rio Sul para uma amostra de aproximadamente um milh?o de gal?xias. Foram identificados 53 novos candidatos a Sistemas do Tipo-M51, os quais podem ser confirmados em estudos posteriores, como por exemplo, espectrosc?picos. A relev?ncia de tal estudo deve ser ressaltada, tendo-se em vista que atualmente existem 232 Sistemas do Tipo-51 confirmados e outros 430 candidatos.Submitted by Ricardo Cedraz Duque Moliterno (ricardo.moliterno@uefs.br) on 2019-04-03T22:47:15Z No. of bitstreams: 1 Disserta__o (1).pdf: 5420302 bytes, checksum: d5e6aa040449b4743dae74db39baaafb (MD5)Made available in DSpace on 2019-04-03T22:47:15Z (GMT).
