Monthly Notices : Radiative shocks in galaxy formation ( II ) 3
I use a 1-D Lagrangian code which follows both a gaseous and a dark component to study the effects of a metagalactic UV background on the formation of dwarf galaxies. In the case of an ionising background consistent with the existing observational constraints no effect has been found in halos with circular velocity above 60 km s −1. The effect is very mild in halos with 40 < V c < 60 km s −1 , ...

We investigate the effects that starspots have on the light curves of eclipsing binaries and in particular how they may affect the accurate measurement of eclipse timings. Concentrating on systems containing a low-mass main-sequence star and a white dwarf, we find that if starspots exhibit the Wilson depression they can alter the times of primary eclipse ingress and egress by several seconds fo...

What does it mean to be a ‘‘just’’ and ‘‘caring’’ society when we have only limited resources to meet virtually unlimited health care needs? In Just Caring. Health Care Rationing and Democratic Deliberation Leonard Fleck identifies health care rationing as the moral problem of contemporary health care. At present, millions of Americans go without health insurance, thousands of whom die prematur...
متن کاملAccepted for publication in Monthly Notices of the R . A . S . Old high - redshift galaxies and primordial density fluctuation spectra
We have discovered a population of extremely red galaxies at z ≃ 1.5 which have apparent stellar ages of > ∼ 3 Gyr, based on detailed spectroscopy in the rest-frame ultraviolet. In order for galaxies to have existed at the high collapse redshifts indicated by these ages, there must be a minimum level of power in the density fluctuation spectrum on galaxy scales. This paper compares the required...
