Multi-wavelength Polarimetry and Variability Study of M87 Jet
Sayali S Avachat, Eric S Perlman, William B Sparks +2
We present a high resolution polarimetry and variability study of the M87 jet using VLA and HST data taken during 2002 to 2008. Both data-sets have an angular resolution as high as…
New Constraints on Quantum Gravity from X-ray and Gamma-Ray Observations
Eric S. Perlman, Saul A. Rappaport, Wayne A. Christensen +3
One aspect of the quantum nature of spacetime is its "foaminess" at very small scales. Many models for spacetime foam are defined by the accumulation power , which parameterizes…
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…
Polarized Mid-Infrared Synchrotron Emission in the Core of Cygnus A
E. Lopez-Rodriguez, C. Packham, C. Tadhunter +10
We present high-angular (~0.4") resolution mid-infrared (MIR) polarimetric observations in the 8.7 m and 11.6 m filters of Cygnus A using CanariCam on the 10.4-m Gran Telesco…
Near- to Mid- Infrared Imaging and Spectroscopy of Two Buried AGNs of the Nearby Merging Galaxy NGC 6240 with Subaru/IRCS+AO and GTC/CanariCam
Tamami I. Mori, Masatoshi Imanishi, Almudena Alonso-Herrero +7
We report near-infrared K', L', and M' band imaging observations of the nearby merging galaxy NGC 6240 with the Infrared Camera and Spectrograph on the Subaru telescope. The observ…
Subaru Spectroscopy and Spectral Modeling of Cygnus A
Matthew J. Merlo, Eric S. Perlman, Robert Nikutta +6
We present high angular resolution (0.5) MIR spectra of the powerful radio galaxy, Cygnus A, obtained with the Subaru telescope. The overall shape of the sp…
