The SWIRE Template Library



A library of galaxy and AGN templates & Photometric redshift estimates


Existing template libraries with infrared coverage (Devriendt et al. 1999; Silva et al. 1998, Chary and Elbaz 2000, Dale and Helou 2002) do not represent the whole variety of optical-IR SEDs or lack sufficient accuracy and resolution in modeling the IR spectral features. I created a library of galaxy and AGN templates using models, broad-band photometry, and observed spectra. The templates represent various galaxy spectral types, including AGN, and cover a broad wavelength range (from the ultraviolet to the radio).
Check this link for a detailed description of the template library and to download it.

I estimate photometric redshifts using the Hyper-z photometric redshift code (Bolzonella et al. 2000). See applications of this technique on specific classes of objects in Pozzi et al. (2007), Polletta et al. (2007), Tajer et al. (2007), Weedman et al. (2006), Siana et al. (2006), Davoodi et al. (2006a, 2006b), Polletta et al. (2006), Franceschini et al. (2005), Hatziminaoglou et al. (2005), Jarrett et al. (2005), and Lonsdale et al. (2004).

Galaxy evolution in dense environments


Galaxies in overdense environments at early epochs undergo earlier and faster evolution than field galaxies and become the passive and massive galaxies that populate local galaxy clusters. To determine which processes intervene in their evolution and at which epochs, it is necessary to find galaxy overdensities, and identify and study their galaxy members. Since galaxy overdensities are extended and contain galaxies of different types, the identification and study of their members require spectroscopic and photometric data over large regions and across the whole multi-wavelength spectrum.
