The AGNIFS survey: distribution and excitation of the hot molecular and ionised gas in the inner kpc of nearby AGN hosts
R. A. Riffel, T. Storchi-Bergmann, R. Riffel +13
We use the Gemini NIFS instrument to map the Hm and Br flux distributions in the inner 0.04-2 kpc of a sample of 36 nearby active galaxies ($0.001\lesssim z\lesssim0…
Gemini NIFS survey of feeding and feedback in nearby Active Galaxies -- IV. Excitation
Rogemar A. Riffel, Marina Bianchin, Rogerio Riffel +5
The near-infrared spectra of Active Galactic Nuclei (AGN) present emission lines of different atomic and molecular species. The mechanisms involved in the origin of these emission…
Gemini NIFS survey of feeding and feedback in nearbyActive Galaxies - III. Ionized versus warm molecular gasmasses and distributions
Astor J. Schonell, Thaisa Storchi-Bergmann, Rogemar A. Riffel +5
We have used the Gemini Near-Infrared Integral Field Spectrograph (NIFS) in the J and K bands to map the distribution, excitation and kinematics of the ionized HII and warm molecul…
Gemini NIFS survey of feeding and feedback processes in nearby Active Galaxies: II -The sample and surface mass density profiles
R. A. Riffel, T. Storchi-Bergmann, R. Riffel +10
We present and characterize a sample of 20 nearby Seyfert galaxies selected for having BAT 14--195keV luminosities erg s, redshift 0.015, being acc…
Electromagnetic ion-cyclotron instability in a dusty plasma with product-bi-kappa distributions for the plasma particles
Michel S. dos Santos, Luiz F. Ziebell, Rudi Gaelzer
We study the dispersion relation for parallel propagating ion-cyclotron (IC) waves in a dusty plasma, considering situations where the velocity dispersion along perpendicular direc…
