Abstract:
We present the results of a Hubble Space Telescope ACS/HRC FUV,
ACS/WFC optical study into the cluster populations of a sample of
22 Luminous Infrared Galaxies in the Great Observatories All-Sky LIRG
Survey. Through integrated broadband photometry, we have derived ages
and masses for a total of 484 star clusters contained within these
systems. This allows us to examine the properties of star clusters
found in the extreme environments of LIRGs relative to lower
luminosity star-forming galaxies in the local universe. We find that
by adopting a Bruzual & Charlot (2003MNRAS.344.1000B 2003MNRAS.344.1000B) simple stellar
population model and Salpeter (1955ApJ...121..161S 1955ApJ...121..161S) initial mass
function, the age distribution of the clusters declines as
dN/dτ=τ-0.9±0.3, consistent with the age distribution
derived for the Antennae Galaxies, and interpreted as evidence for
rapid cluster disruption occurring in the strong tidal fields of
merging galaxies. The large number of 106M☉ young clusters
identified in the sample also suggests that LIRGs are capable of
producing more high-mass clusters than what is observed to date in any
lower luminosity star-forming galaxy in the local universe. The
observed cluster mass distribution of dN/dM=M-1.95±0.11 is
consistent with the canonical -2 power law used to describe the
underlying initial cluster mass function (ICMF) for a wide range of
galactic environments. We interpret this as evidence against
mass-dependent cluster disruption, which would flatten the observed
CMF relative to the underlying ICMF distribution.
Description:
The HST B-band (F435W) and I-band (F814W) images were obtained with
the Wide Field Camera (WFC) on the Advanced Camera for Surveys (ACS)
during the period 2005 August to 2007 January (PI: A. Evans; PID 10592).
The approximate integration times for each filter were 21 minutes in
F435W and 12 minutes in F814W.
The HST far-UV (F140LP) and optical images in the sample were obtained
with the Solar Blind Channel (SBC) on the Advanced Camera for Surveys
(ACS) during the period 2008 April-2009 August (PID 11196; PI: A. Evans).
