The impact of void environment on AGN
Laura Ceccarelli, Fernanda Duplancic, Diego Garcia Lambas
We study the population of active galaxies in void environment in the SDSS. We use optical spectroscopic information to analyze characteristics of the emission lines of galaxies, a…
Properties of galaxies with ring structures
Julia Fernandez, Sol Alonso, Valeria Mesa +2
Aims: We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods: We…
AGNs in Small Galaxy Systems: comparing the main properties of active objects in pairs, triplets and groups
Fernanda Duplancic, Diego G. Lambas, Sol Alonso +1
We perform a comparative study of AGNs in pairs, triplets and groups. To this end we use the Duplancic et al. catalogue of small galaxy systems and consider BPT and WHAN diagnostic…
Overdensity of VVV galaxies behind the Galactic bulge
Daniela Galdeano, Luis Pereyra, Fernanda Duplancic +7
We studied a region of 1.636 square degrees corresponding to the VVV tile . Using SExtractor, we analysed photometric data generating a catalogue of extended sources in this…
