Event Details

Supernovae have been used to measure distances for decades leading to our current understanding of an accelerating, expanding universe. Using these supernovae as standard candles requires any non-uniformity to be understood and calibrated out. I will describe the historical differences amongst these standard candles and the current uncertainties affecting cosmological measurements. I will especially focus on the unexpected differences found in the ultraviolet and what we are doing at Texas A&M to better understand the nature and differences of these explosions.
