2020.12.04 12:18 - Anna RędaszekA key discovery from the Infrared Astronomical Satellite (IRAS) was the existence of dusty galaxies with remarkably high infrared (IR) luminosity LIR (integrated between 8 and 1000 μm). The most extreme kind are what's known as hyperluminous infrared galaxies (which emit over 90% of their energy in the IR) with IR luminosities greater than 10^13 L_solar. If the IR luminosity is solely due to star formation, the star-formation rate of HLIRGs would exceed 1000 M_solar/yr.
Precise tests of General Relativity with ultra-compact radio quasars and strong gravitational lensing

2020.11.19 13:47 - Katarzyna KuźniarThousands of extrasolar planets have been discovered up to date. Although many of the known exoplanets do not resemble those in our solar system, they have one thing in common - they all orbit a star. However, theories of planet formation and evolution predict the existence of free-floating planets, gravitationally unattached to any star.
Status of the Concordance Model of Cosmology
2020.11.09 11:39 - Anna Rędaszek
I review the status of the concordance (standard) LCDM model of cosmology in light of current observations discussing about the apparent tensions in estimation of the key cosmological parameters. I will also briefly discuss the future of the field at the era of the next generation of astronomical/cosmological surveys.
Serdecznie zapraszam,
