Interpreting the Observed Clustering of Red Galaxies at Z ∼ 3
Daddi et al. have recently reported strong clustering of a population of red galaxies at z∼3 in the Hubble Deep Field–South. Fitting the observed angular clustering with a power law of index −0.8, they infer a comoving correlation length r0 ∼ 8h Mpc; for a standard cosmology, this r0 would imply that the red galaxies reside in rare, M ≥ 10hM⊙ halos, with each halo hosting ∼ 100 galaxies to matc...
متن کاملThe blazar GB 1428 + 4217 : a warm absorber at z = 4 . 72 ?
BeppoSAX observations of the high redshift (z = 4.72) blazar GB 1428+4217 confirm the presence of a complex soft X–ray spectrum first seen with the ROSAT PSPC. Flattening below a rest frame energy of 5 keV can be accounted for by absorption from an equivalent column density of (cold) gas with NH ∼ 8 × 10 cm−2. Below 2 keV a (variable) excess of a factor ∼ 20 above the extrapolated absorbed spec...
متن کاملA first direct measurement of the intergalactic medium temperature around a quasar at z 6
The thermal state of the intergalactic medium (IGM) provides an indirect probe of both the H I and He II reionization epochs. Current constraints on the IGM temperature from the Lyα forest are restricted to the redshift range 2 ≤ z ≤ 4.5, limiting the ability to probe the thermal memory of H I reionization towards higher redshift. In this work, we present the first direct measurement of the IGM...
متن کامل6 Snapping Supernovae at z > 1 . 7
We examine the utility of very high redshift Type Ia supernovae for cosmology and systematic uncertainty control. Next generation space surveys such as the Supernova/Acceleration Probe (SNAP) will obtain thousands of supernovae at z > 1.7, beyond the design redshift for which the supernovae will be exquisitely characterized. We find that any z & 2 standard candles’ use for cosmological paramete...
متن کاملQuasars at Z=6: the Survival of the Fittest
The Sloan Digital Sky survey detected luminous quasars at very high redshift, z > 6. Follow-up observations indicated that at least some of these quasars are powered by supermassive black holes (SMBHs) with masses in excess of 10M⊙. SMBHs, therefore, seem to have already existed when the Universe was less than 1 Gyr old, and the bulk of galaxy formation still has to take place. We investigate i...
