Type Ia supernovae as extragalactic distance indicators

    Research output: Contribution to journalMeeting Abstractpeer-review

    Abstract

    Type Ia supernovae (SNe Ia) are among cosmologys most useful tools for measuring extragalactic distances. Their intrinsic brightness, MV = −19.2 mag, and precision, σ = 0.12 mag, make for a unique combination to precisely probe cosmic expansion from the nearby to the high-redshift Universe. I describe the current state of the art for measuring distances to SNe Iafocusing on the current challenges which ultimately limit their precisionas well as prospects for further refinement. I also highlight cosmological applications where they have been especially valuable, and briefly review some future projects which plan to exploit SNe Ia.
