We measure a relation between the depth of four prominent rest-UV absorption complexes and metallicity for local galaxies and verify it up to z~3. We then apply this relation to a sample of 224 galaxies at 3.5 < z < 6.0 ( = 4.8) in COSMOS, for which

We present an atlas of 88 z ~ 5.7 and 30 z ~ 6.5 Lyα emitters obtained from a wide-field narrowband survey. We combined deep narrowband imaging in 120 A bandpass filters centered at 8150 A and 9140 A with deep B V R I z broadband imaging to select h

Dust Attenuation in High Redshift Galaxies -- 'Diamonds in the Sky'

Autor: Y. Kakazu, Andreas L. Faisst, Gongjie Li, Nick Scoville, Peter Capak, Charles L. Steinhardt

We use observed optical to near infrared spectral energy distributions (SEDs) of 266 galaxies in the COSMOS survey to derive the wavelength dependence of the dust attenuation at high redshift. All of the galaxies have spectroscopic redshifts in the r

We investigate spectroscopically measured Ly{\alpha} equivalent widths and escape fractions of 244 sources of which 95 are Lyman Break Galaxies (LBGs) and 106 Lyman Alpha Emitters (LAEs) at z~4.2, z~4.8, and z~5.6 selected from intermediate and narro
