In this talk Dr de Lera Acedo will discuss the science behind understanding how the first stars formed and ionised the intergalactic medium, ~ 300 Myears after the Big Bang, effectively transforming a mostly simple and empty Universe into the realm of complex celestial objects we now know it to be today. The SKA, with its unprecedented imaging capabilities, will in a few years be able to image this unexplored epoch of the infant Universe, and a series of precursor instruments are already paving the way. He will discuss these, their science cases and their latest results.
Dr de Lera Acedo is a STFC Ernest Rutherford Fellow at the Cavendish Astrophysics laboratory of the University of Cambridge, from where he leads the Cavendish Radio Cosmology group and the REACH (Radio Experiment for the Analysis of Cosmic Hydrogen) project. Dr de Lera Acedo’s career started designing radio antennas and modelling and calibration techniques for the Square Kilometre Array telescope, and over the last decade has transitioned to cosmology research of the early epochs of the Universe using highly precise calibrated radiometers. The Cosmic Dawn (birth of the first stars) and the Epoch of Re-ionization (subsequent shaping of the InterGalactic Medium by those first stars) are the two unexplored epochs under study by Dr de Lera Acedo’s group at Cambridge.
Dr de Lera Acedo will give the lecture remotely from Cambridge via Zoom. It can be attended remotely on Zoom or in the room at the BRLSI where it will projected.
