Via Fourier analysis, applied to broad-band images of a sample of spiral galaxies, the relative contribution of each spiral mode to the spiral arms, as a...
Spiral Resonance Structure of NGC4321 from HI Data
NGC4321 is a two-armed grand design spiral galaxy in the Virgo Cluster. HI emission line data with 15 arcsecond resolution from the VLA map the velocity field...
The IR data come from the Herschel/SPIRE Science Demonstration Phase (SDP) observations of the Great Observatories Origins Deep Survey (GOODS)-North, taken as...
Spitzer Imaging of Herschel Lensed Sub-mm Galaxies
Sub-millimeter surveys have, in the last decade, revealed an unexpected population of high-redshift dust-obscured sub-mm galaxies (SMGs) which are forming stars...
Spitzer IRS spectra of compact Galactic planetary nebulae: The link between dust, evolution, and metallicity
A sample of ~150 compact Galactic PNe has been observed with the Spitzer/IRS spectrograph to characterize their dust properties. These PNe are likely to be at...
Spitzer IRS Spectroscopy of Infrared-Luminous Galaxies at z ˜0.5-3
We present results on low-resolution mid-infrared spectroscopy of a sample of 70 infrared-luminous galaxies and quasars obtained with the Infrared Spectrograph...
Spitzer mid-IR spectroscopy of LIRGs (Hernan-Caballero+, 2009)
All targets were observed in the two low-resolution modules of the IRS, short low (SL) and long low (LL), exposing the two subslits on each of them (SL1, SL2...
