Meeting / Address:
Winchester Discovery Centre, Jewry Street, Winchester
England

All Cafe Sci talks at Winchester Discovery Centre, Jewry Street are free to attend. Please arrive from 7.15pm for 7.45 start unless otherwise advertised. Licensed bar serving hot drinks, cakes and snacks. No charge to attend. Contributions welcome. Most massive galaxies in the universe today harbor supermassive black holes (SMBHs), with masses from a few million to tens of billions of solar masses. But very bright quasars powered by billion solar mass BHs have now been discovered at redshift z ~ 7, or just 775 million years after the Big Bang. They pose serious challenges to current theories of cosmological structure formation because it is not known how BHs this massive appeared by such early epochs. I will discuss the possible origins of the first quasars and present new supercomputer simulations of how they could form in the first billion years of the universe.
