Abstract:
Using data from the Wide-field Infrared Survey Explorer mission, we
have measured near infra-red (NIR) photometry of a diverse sample of
dust-free stellar systems (globular clusters, dwarf and giant
early-type galaxies) which have metallicities that span the range
-2.2<[Fe/H](dex)<0.3.
Description:
We selected an initial sample of Milky Way (MW) Globular Clusters
(GCs) drawn from the Harris catalog (1996AJ....112.1487H 1996AJ....112.1487H, 2010 edition)
supplemented with a sample of Large and Small Magellanic Cloud GCs
drawn from McLaughlin & van der Marel (2005, Cat. J/ApJS/161/304).
To augment the MW GC sample we also make use of WISE photometry of
spectroscopically confirmed M31 GCs drawn from the Revised Bologna
Catalog of M31 GCs (RBC; Galleti et al. 2004A&A...416..917G 2004A&A...416..917G). To the
RBC we add additional age and metallicity measurements from the
literature (Ma et al. 2009AJ....137.4884M 2009AJ....137.4884M; Wang et al. 2010,
J/AJ/139/1438; Caldwell et al. 2011, J/AJ/141/61 ; Cezario et al.
2013, J/A+A/549/A60) to produce the largest possible catalog of
spectroscopically confirmed M31 GCs with stellar population
measurements.
In addition to the GC samples we also examine the WISE colors of
early-type galaxies (ETGs). Our main ETG sample is that of the SAURON
survey (de Zeeuw et al. 2002MNRAS.329..513D 2002MNRAS.329..513D). We also added additional
dwarf and giant ETGs using derived properties provided in the papers
of Michielsen et al. (2008MNRAS.385.1374M 2008MNRAS.385.1374M), Koleva et al.
(2011MNRAS.417.1643K 2011MNRAS.417.1643K), and Forbes et al. (2011MNRAS.413.2665F 2011MNRAS.413.2665F).
Finally, we added higher-mass ETGs from the study of Denicolo et al.
(2005MNRAS.358..813D 2005MNRAS.358..813D).
