Torus and AGN properties of nearby Seyfert galaxies: Results from fitting IR spectral energy distributions and spectroscopy
Almudena Alonso-Herrero, Cristina Ramos Almeida, Rachel Mason +9
We used the CLUMPY torus models and a Bayesian approach to fit the infrared spectral energy distributions (SEDs) and ground-based high-angular resolution mid-infrared spectroscopy…
Mid-Infrared Imaging of Nearby Radio-Loud AGN
Eric S. Perlman, Matthew Merlo, Christopher Packham +2
We present high spatial resolution MIR observations for several nearby radio loud active galactic nuclei (RLAGN), which were obtained using the Gemini North and South telescopes. O…
GNOMOS: The Gemini NIR-Optical Multi Object Spectrograph
Ricardo P. Schiavon, Andy Adamson, Kristin Chiboucas +20
This paper is a response to a call for white papers solicited by Gemini Observatory and its Science and Technology Advisory Committee, to help define the science case and requireme…
Differences between CO- and calcium triplet-derived velocity dispersions in spiral galaxies: evidence for central star formation?
Rogemar A. Riffel, Luis C. Ho, Rachel Mason +16
We examine the stellar velocity dispersions (sigma) of a sample of 48 galaxies, 35 of which are spirals, from the Palomar nearby galaxy survey. It is known that for ultra-luminous…
Gemini Imaging of Mid-IR Emission from the Nuclear Region of Centaurus A
James T. Radomski, Christopher Packham, N. A. Levenson +7
We present high spatial resolution mid-IR images of the nuclear region of NGC 5128 (Centaurus A). Images were obtained at 8.8 micron, N-band (10.4 micron), and 18.3 micron using th…
A close look at the dwarf AGN of NGC 4395: optical and near-IR integral field spectroscopy
Carine Brum, Marlon R. Diniz, Rogemar A. Riffel +7
Intermediate mass black holes (10-10 M) in the center of dwarf galaxies are believed to be analogous to growing Active Galactic Nuclei (AGN) in the early Universe.…
