Hello, my name is Enrique Gaztanaga. I'm research Professor at the Institute of Space Sciences (CSIC, IEEEC). I teach graduate courses in Cosmology and have co-led hundreds of peer reviewed publications in Cosmology and Astrophysics. I work both on theoretical and observational topics and have helped build and analyze several international Cosmic Experiments. I am writing this blog to bring front line research to interested readers and to question our knowledge of the Universe around us.
