The current cosmological model rests on Einstein's theory of general relativity. In order for it to be consistent with large-scale structure data, the existence of cosmologically relevant physical processes need to be postulated: inflation, cold or...

The field of dark matter study has reported a number of anomalies in recent years, and the upcoming generation of experiments hopes to directly detect particles from the local halo population through scattering off nuclei in underground detectors...

ABSTRACT: Deep exposures with the Hubble Space Telescope (HST) have provided the primary evidence that star-forming galaxies were present in the first billion years of cosmic history. Sometime during this early period the intergalactic medium...

ABSTRACT: Multiwavelength surveys like GOODS and COSMOS indicate that most actively growing black holes are heavily obscured, and this fraction increases in the young Universe and in lower luminosity AGN. Most black holes grow in moderate luminosity...

The cosmological model based on cold dark matter (CDM) and dark energy has been hugely successful in describing the observed evolution and large scale structure of our Universe. However, at small scales (in the smallest galaxies and at the centers...

The Kepler survey has revolutionized the field of exoplanets by its discovery of thousands of transiting planet candidates. However, translating the Kepler discoveries into knowledge about the underlying demographics of exoplanets is a non-trivial...
