Additional Constraints

Observers studying the cosmology and evolutionary history of our Universe through the statistical properties of ‘normal’ galaxies have four main tools at their disposal. (1) The number-redshift relation. Although a very powerful diagnostic, spectroscopic surveys are currently limited to B < 24m and significantly incomplete in the range, 23m< B < 24m. (2) Galaxy number-magnitude counts. Although by themselves, they cannot constrain models as tightly as spectroscopy, they can be measured ∼ 4m fainter, where cosmological effects are expected to be significant. (3) Galaxy colours over a wide wavelength range, which provide additional constraints. (4) The dependence of galaxy clustering with magnitude. ω(θ) can be measured to the limit of the counts.Here we report on the latest Durham count and clustering work.

Tentative Explanation

The surface microstructured silicon prepared by femtosecond laser pulses irradiation in SF6shows significantly enhanced light absorption over a wide wavelength range. Absorptance of microstructured silicon is measured from 2 to 16μm, and the absorptance can up to 0.8 in the measured wavelength range. The absorptance of microstructured silicon increases as the height of spikes increases. Emissivity of microstructured silicon at different temperatures(100°C-400°C) is measured from 2.5μm to 25μm. Greatly enhanced emissivity compared to that of flat silicon was observed. At a certain temperature, with increasing the height of the spikes, the emissivity increases. For a sample with 13–14μm high spikes, the emissivity at a temperature of 100°C is approximately 0.96. A tentative explanation for the high absorptance of microstructured silicon has been carried out from three aspects: impurity states, structure defects and multiple reflection of light between spikes. The excellent properties of microstructured silicon make it a promising candidate for applications of infrared detectors, silicon solar cells, flat blackbody source and so on.
