Abstract:
Emission from active galactic nuclei (AGNs) is known to play an
important role in the evolution of many galaxies including luminous
and ultraluminous systems (U/LIRGs), as well as merging systems.
However, the extent, duration, and exact effects of its influence are
still imperfectly understood, as are the conditions that lead to it
dominating the IR emission, and then fading again after coalescence.
To assess the impact of AGNs on interacting systems, we present a
Spectral Energy Distribution (SED) analysis of a sample of 188 nearby
galaxies We gather and systematically re-reduce archival broad-band
imaging mosaics from the ultraviolet to the far-infrared using data
from GALEX, SDSS, 2MASS, IRAS, WISE, Spitzer, and Herschel. We use
spectroscopy from Spitzer/IRS to obtain fluxes from fine-structure
lines that trace star formation and AGN activity. Utilizing the SED
modelling and fitting tool CIGALE, we derive the physical conditions
of the interstellar medium, both in star-forming regions and in
nuclear regions dominated by the AGN in these galaxies. We investigate
how the star formation rates (SFRs) and the fractional AGN
contributions (fAGN) depend on stellar mass, galaxy type, and merger
stage. We find that luminous galaxies more massive than about 10^10M*
are likely to deviate significantly from the conventional galaxy
main-sequence relation. Interestingly, infrared AGN luminosity and
stellar mass in this set of objects are much tighter than SFR and
stellar mass. We find that buried AGNs may occupy a locus between
bright starbursts and pure AGNs in the fAGN-[NeV]/[NeII] plane. We
identify a modest correlation between fAGN and mergers in their later
stages.
Description:
We present the basic data, photometry and derived parameters from the
four samples of galaxies presented in this work. Tables A1-A4 in the
article are cds tables: SIGS, SB, AGN and LSM. Tables A6-A9 are
combined in Photometry.cds and Tables A10-A13 are combined in
Parameters.cds. Table A14, contains the derived parameters for six AGN
galaxies where a different viewing angle was used.
