In the first part of this talk I will present a historical review of the CMB observations, one of the most powerful cosmological probes. Following the first...
Cosmological giants and elves: galaxy formation and the small scale of cold dark matter
I will review the status of our understanding of galaxy formation in the prevailing cold dark matter paradigm. After reviewing the successes and failures of the...
Cosmological implications of the clustering of galaxies in BOSS
Driven by the potential of large-scale structure (LSS) observations to shed light on the physics behind the accelerated expansion of the Universe, several...
Cosmology on small scales: the structure of (mostly) dark matter halos
The standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...
Cosmology with a new observable: Angular Redshift Fluctuations (ARF)
In cosmology, it is customary to convert observed redshifts into distances in order to study the large scale distribution of matter probes like galaxies and...
Critical Tests of Theory of the Early Universe using the Cosmic Microwave Background
The Cosmic Microwave Background (CMB), the fossil light of the BigBang, is the oldest light that one can ever hope to observe in ourUniverse. The CMB provides...
I will discuss how the acoustic oscillations that propagate in the photon-baryon fluid during the first million years of the Universe provide a robust method...
