May 23rd: The iSTEM Club of BRHS hosted guest speaker, Prof. Michael Strauss of Princeton University.

Prof. Michael Strauss is interested in all aspects of extragalactic astronomy and observational cosmology.  He has used large surveys suchas IRAS and the Sloan Digital Sky Survey, to study the large-scale distribution of galaxies to constrain cosmological parameters, the relationship between galaxy properties and their environment, and the nature and evolution of AGN and quasars.

He is involved in planning for the next generation of large surveys, including Hyper-SuprimeCam on Subaru, and the Large Synoptic Survey Telescope.

 

Prof. Strauss shows the students the shape of the galaxy.

 

Prof. Strauss talks about a graph displaying how the recession velocity is proportional to distance (The Hubble Law), implying uniform expansion.

 

Prof. Strauss points to a current map of the Universe.
