A local luminosity function at 15$\mu m$ is derived using the bivariate (15$\mu m$ vs. 60$\mu m$ luminosity) method, based on the newly published ISOCAM LW3-band (15$\mu m$) survey of the very deep IRAS 60$\mu m$ sample in the north…

There exists an inevitable scatter in intrinsic luminosity of Gamma Ray Bursts(GRBs). If there is relativistic beaming in the source, viewing angle variation necessarily introduces variation in the intrinsic luminosity function(ILF).…

Photometric redshift estimation is an indispensable tool of precision cosmology. One problem that plagues the use of this tool in the era of large-scale sky surveys is that the bright galaxies that are selected for spectroscopic observation…
