Homogeneous vs Biased IGM: Impact on Reionization
Frontiers in Astronomy and Space Sciences, 2021 This paper considers the impact of large scale biasing of the IGM on reionization. The two simplest but extreme scenarios for IGM biasing are: an unbiased IGM which has a constant density and an IGM with density equal to the collapsed matter density.

Colour of baked products during baking
Czech Journal of Food Sciences, 2000 The parameters of the colour of the surface of bakery products - brightness L*, a* for red and b* for yellow colour - were measured at different temperature regimes. The parameters were found to change during the time of baking.

Space VLBI Observations Show $T_b > 10^{12} K$ in the Quasar NRAO 530 [PDF]
, 1998 We present here space-based VLBI observations with VSOP and a southern hemisphere ground array of the gamma-ray blazar NRAO 530 at 1.6 GHz and 5 GHz. The brightness temperature of the core at 1.6 GHz is $5 \times 10^{11}$ K.
