Variations in the 6.2 m polycyclic aromatic hydrocarbon band in Active Galactic Nuclei- and Starburst-dominated galaxies
Carla M. Canelo, Dinalva A. Sales, Vitor Avelaneda +3
Polycyclic aromatic hydrocarbons (PAHs) are fundamental to understanding the interstellar medium (ISM) of several astrophysical objects. Normally present in Starburst (SB) galaxies…
Digging deeper into NGC 6868 II: ionized gas and excitation mechanism
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +9
We studied the ionized gas in the inner region ( pc) of the galaxy NGC 6868 using Gemini/GMOS integral field unit observations. Channel maps reveal complex ki…
A study of interacting galaxies from the Arp-Madore Catalogue: Triggering of star formation and nuclear activity
Pedro H. Cezar, Miriani G. Pastoriza, Rogério Riffel +3
We present Gemini Multi-Object Spectrograph (GMOS) spectroscopic observations of 95 galaxies from the Arp & Madore (1987) catalogue of peculiar galaxies. These galaxies have been s…
Digging deeper into NGC\,6868 I: stellar population
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +8
We use Gemini integral field unit observations to map the stellar population properties in the inner region ( pc) of the galaxy NGC 6868. In order to understa…
Profile comparison of the 6-9 m polycyclic aromatic hydrocarbon bands in starburst-dominated galaxies
Carla M. Canelo, Dinalva A. Sales, Amâncio C. S. Friaça +2
Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and 8.6 m…
A Gemini-NIFS view of the merger remnant NGC 34
J. C. Motter, R. Riffel, T. V. Ricci +8
The merger remnant NGC 34 is a local luminous infrared galaxy (LIRG) hosting a nuclear starburst and a hard X-ray source associated with a putative, obscured Seyfert~2 nucleus. In…
