Polarization and brightness temperature observations of Venus with the GMRT [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Venus was observed at frequencies of 1297.67 MHz (23 cm), 607.67 MHz (49 cm) and 233.67 MHz (1.28 m) with the Giant Metrewave Radio Telescope (GMRT) during the period of 25th July and 6th September 2015 when it was close to its inferior conjunction. Values of the brightness temperature (Tb) of Venus from these observations were derived as 622{\pm}43 K,

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.
