2 00 9 Spectral Energy Distribution Fitting : Application to Ly α - Emitting Galaxies ⋆
Spectral Energy Distribution (SED) fitting is a well-developed astrophysical tool that has recently been applied to high-redshift Lyα-emitting galaxies. If rest-frame ultraviolet through near-infrared photometry is available, it allows the simultaneous determination of the star formation history and dust extinction of a galaxy. Lyαemitter SED fitting results from the literature find star format...
متن کاملDecomposing Dusty Galaxies. I. Multi-component Spectral Energy Distribution Fitting
We present a new multi-component spectral energy distribution (SED) decomposition method and use it to analyze the ultraviolet to millimeter wavelength SEDs of a sample of dusty infrared-luminous galaxies. SEDs are constructed from spectroscopic and photometric data obtained with the Spitzer Space Telescope in conjunction with photometry from the literature. Each SED is decomposed into emission...
متن کاملEMITTING AND Lyα ABSORBING GALAXIES
The spectral properties of Lyman break galaxies (LBGs) offer a means to isolate pure samples displaying either dominant Lyα in absorption or Lyα in emission using broadband information alone. We present criteria developed using a large z ∼ 3 LBG spectroscopic sample from the literature that enables large numbers of each spectral type to be gathered in photometric data, providing good statistics...
متن کاملThe Spectral Energy Distribution of Spiral Galaxies
Spectral energy distributions (SEDs) are some of the most important sources of information for galaxies, especially for high redshift ones. Here we review recent work on the subject. We discuss the integrated spectra of galaxies of different morphological and activity type, their application to derive K-corrections and classification of high redshift objects. We also discuss the radio to X-rays...
متن کاملA Group of Red, Lyα Emitting, High Redshift Galaxies
We have discovered two new high redshift (z = 2.38) galaxies, near the previously known z = 2.38 galaxy 2139−4434 B1 (Francis et al. 1996). All three galaxies are strong Lyα emitters, and have much redder continuum colors (I − K ∼ 5) than other optically-selected high redshift galaxies. We hypothesize that these three galaxies are QSO IIs; radio-quiet counterparts of high redshift radio galaxie...
