NGC 3256 N Archives

The first two principal components for a data cube of H2 of NGC 3256 N. The left panels show the tomograms of each component which describes the spatial intensity of each eigenspectrum. The black crosses show the peak continuum position at this wavelength. The right panels show the eigenspectrum of each principal component. The horizontal dashed lines show where the weight is zero and the vertical dashed lines show the kinematic centre, determined by the peak wavelength of the first principal component. The first component describes the rest frame emission, while the second captures rotation of the gas. -- astro-ph.GA

The Kinematics of Polycyclic Aromatic Hydrocarbons (PAHs) in Galaxies revealed by Principal Component Analysis (PCA) tomography with JWST/NIRSpec

by Keith CowingMay 24, 2024May 24, 2024

Polycyclic Aromatic Hydrocarbons (PAHs) are organic molecules which comprise the smallest particles of dust in the interstellar medium (ISM). Due to their broad/complex emission profiles, obtaining kinematics is a challenge […]
