This is a review talk on the UV and infrared selected galaxies. The central question addressed is: do UV and infrared surveys see the 2 sides of star formation of the same population, or star formation of 2 different populations? We first review the literature on the UV and IR selected galaxy samples, try to quantify the difference and overlaps between these two populations of star forming galaxies. We then present some preliminary results of a GALEX/SWIRE comparison study for IR and UV selected galaxies at z=0.6, in an attempt to constrain the evolution of the dust attenuation and of stellar mass of these galaxies.
The previously developed bistable amphoteric native defect (BAND) model is used for a comprehensive explanation of the unique photophysical properties and for understanding the remarkable performance of perovskites as photovoltaic materials. It is sh
Condensation of bosons causes spectacular phenomena such as superfluidity or superconductivity. Understanding the nature of the condensed particles is crucial for active control of such quantum phases. Fascinating possibilities emerge from condensate
We discuss our recently proposed interpretation of the discrepancy between the bottle and beam neutron lifetime experiments as a sign of a dark sector. The difference between the outcomes of the two types of measurements is explained by the existence
Although the cosmic concordance cosmology is quite successful in fitting data, fine tuning and coincidence problems apparently weaken it. We review several possibilities to ease its problems, by considering various kinds of dynamical Dark Energy and
How and when did galaxies form and assemble their stars and stellar mass? The answer to these questions, so crucial to astrophysics and cosmology, requires the full reconstruction of the so called cosmic star formation rate density (SFRD), i.e. the e
