INSPIRE: INvestigating Stellar Population In RElics -- I. Survey presentation and pilot program
C. Spiniello, C. Tortora, G. D'Ago +12
Massive ETGs are thought to form through a two-phase process. At early times, an intense and fast starburst forms blue and disk-dominated galaxies. After quenching, the remaining s…
The properties of Polycyclic Aromatic Hydrocarbons in galaxies: constraints on PAH sizes, charge and radiation fields
Dimitra Rigopoulou, Marie Barale, David Clary +7
Based on theoretical spectra computed using Density Functional Theory we study the properties of Polycyclic Aromatic Hydrocarbons (PAH). In particular using bin-average spectra of…
Excitation of Polycyclic Aromatic Hydrocarbon (PAH) Emission: Dependence on Size Distribution, Ionization, and Starlight Spectrum and Intensity
B. T. Draine, Aigen Li, Brandon S. Hensley +3
Using physical models, we study the sensitivity of polycyclic aromatic hydrocarbon (PAH) emission spectra to the character of the illuminating starlight, to the PAH size distributi…
Nature versus nurture: relic nature and environment of the most massive passive galaxies at
C. Tortora, N. R. Napolitano, M. Radovich +13
Relic galaxies are thought to be the progenitors of high-redshift red nuggets that for some reason missed the channels of size growth and evolved passively and undisturbed since th…
[CI](1-0) and [CI](2-1) in resolved local galaxies
Alison F. Crocker, Eric Pellegrini, J. -D. T. Smith +16
We present resolved [CI] line intensities of 18 nearby galaxies observed with the SPIRE FTS spectrometer on the Herschel Space Observatory. We use these data along with resolved CO…
