W swoim wystąpieniu chciałbym opisać proces nazywany kilonowa (od przewidywanej jasności optycznej porównywalnej z tysiącem nowych). Proces ten został przewidziany przez Paczyńskiego i Li. Może on towarzyszyć zlaniu się układu podwójnego dwóch gwiazd neutronowych lub gwiazdy neutronowej i czarnej dziury. W obu tych przypadkach oprócz emisji optycznej zachodzi też emisja fal grawitacyjnych.
Serdecznie zapraszam,
The two currently largest all-sky photometric datasets, WISE and SuperCOSMOS, have been recently cross-matched to construct a novel photometric redshift catalogue on 70% of the sky. Galaxies were separated from stars and quasars through colour cuts, which may leave imperfections because different source types may overlap in colour space.
I will briefly discuss the current status of standard model of cosmology with the emphasis on the GR as its main building block. Then will stress out why is it so important to obtain new and independent tests of Einstein’s gravity on cosmological scales.
I shall discuss some of the currently considered and available tests of the theory and will conclude by presenting my work towards constituting new and largely model-independent tests of GR on intergalactic and cosmological scales.
Serdecznie zapraszam,

Studies at low and intermediate redshift ranges shows that the relation between the luminous structure and underlying dark matter distribution is not straightforward and depend on the various properties of galaxy population. Naturally one would like to extend these studies of the luminous-dark matter relations to the high redshift ranges (z>2) in order to improve our understanding of the evolution of the universe structure.
Studies of the cosmic microwave background (CMB) are today one of the most important pillars of observational cosmology. They provide information on the initial conditions of the Universe and scales
The ESA Planck space mission has fully exploited the cosmological information available in Cosmic Microwave Background temperature anisotropies. A standard cosmological model has emerged. Our Universe, however, remains a mystery. What are the invisible matter and energy that seem to constitute 96% of our universe? Did the Universe truly
begin with an superluminal expansion that stretched quantum fluctuations to cosmological scales to generate the initial
