[postmaster@ADMIN.TRIUMF.CA]

Two more seminars this week that did not make it to the weekly posting.


Date/Time: Sat 2006-03-18 at 10:00  

Location: TRIUMF Auditorium  

Speaker: Paul Hickson (UBC)  

Title: Searching for the First Stars  

Abstract: I will talk about galaxies, the expanding universe, distant objects, the observational challenge,  and large telescopes (Keck,  the 30-metre Telescope and a proposed liquid-mirror telescope on the Moon)   




Date/Time: Sat 2006-03-18 at 10:00  

Location: TRIUMF Auditorium  

Speaker: Ingrid Stairs (UBC)  

Title: Pulsars: Precise Probes of the Universe  

Abstract: Radio pulsars are the cores of massive stars that have undergone supernova explosions.  With one-and-a-half times the mass of our Sun compressed down to the size of a city, and magnetic fields
many times stronger than that of the Earth, they represent an extreme environment that we can't replicate in a lab on Earth. But lighthouse-like radio "pulses" that we detect each time a pulsar
spins allow us to learn about the composition of these bizarre objects, the history of stellar evolution and the structure of our Galaxy, and even to make precise tests of Einstein's theory of General Relativity. This talk will show how we observe these fascinating objects and explore this wide range of scientific areas.
