Understanding the 8 micron vs. Pa-alpha relationship on sub-arcsecond scales in Luminous Infrared Galaxies
Tanio Diaz-Santos, Almudena Alonso-Herrero, Luis Colina +3
This work explores in detail the relation between the 8 micron and the Pa-alpha emissions for 122 HII regions identified in a sample of 10 low-z LIRGs with nearly constant metallic…
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…
12 and 18 micron images of dust surrounding HD 32297
Margaret M. Moerchen, Charles M. Telesco, James M. De Buizer +2
We present the first subarcsecond-resolution images at multiple mid-IR wavelengths of the thermally-emitting dust around the A0 star HD 32297. Our observations with T-ReCS at Gemin…
The Mid-Infrared Emission of M87
E. S. Perlman, R. E. Mason, Christopher Packham +6
We discuss Subaru and Spitzer Space Telescope imaging and spectroscopy of M87 in the mid-infrared from 5-35 um. These observations allow us to investigate mid-IR emission mechanism…
Gemini Mid-IR Polarimetry of NGC1068: Polarized Structures Around the Nucleus
C. Packham, S. Young, R. S. Fisher +7
We present diffraction limited, 10um imaging polarimetry data for the central regions of the archetypal Seyfert AGN, NGC1068. The position angle of polarization is consistent with…
Mid-Infrared T-ReCS Spectroscopy of Local LIRGs
T. Diaz-Santos, A. Alonso-Herrero, L. Colina +3
We present T-ReCS high spatial resolution N-band (8-13 micron) spectroscopy of the central regions (a few kpc) of 3 local LIRGs. The nuclear spectra show deep 9.7 micron silicate a…
