The Sagittarius dwarf irregular galaxy: Metallicity and stellar
... equipped with a 2048 × 2048 Loral CCD, with pixel size of 0.00 26. A readout window was employed to discard the vignetted edges of the CCD, yielding a useful area of 6.0 9 × 6.0 9. Since the tidal radius of SagDig is only ∼1.0 7 (Mateo 1998), no observations of a separate control field were needed. ...

Observational constraints on the electron optical depth32 suggest that an extended, low level of ionization (,10% by volume) may be needed to high redshifts (z . 20) if reionization gradually ends at z < 5.5–8.5. Reconciling the electron scattering ...
