    The synchrony of production and escape: half the bright Lyα emitters at z ≍ 2 have Lyman continuum escape fractions ≍50
    The ionizing photon escape fraction [Lyman continuum (LyC) f esc] of star-forming galaxies is the single greatest unknown in the reionization budget. Stochastic...

    Thermal Instability in a Cooling and Expanding Medium Including Self-Gravity and Conduction
    A systematic study of the linear thermal stability of a medium subject to cooling, self-gravity, and thermal conduction is carried out for the case when the...

    Unbiased studies of galactic outflows
    Large-scale outflows from galaxies are a crucially important yet poorly understood aspect of galaxy evolution. They redistribute gas and metals into the IGM...

    X-ray analysis of Abell 2634 and its central galaxy 3C 465.
    An analysis of a ROSAT/PSPC observation of the galaxy cluster A2634 is presented. The cluster has a luminosity of 7.9+/-0.1x10^43^erg/s in the ROSAT band (0.1-2...
