Biography:Timothy Schrabback
Tim Richard Walter Schrabback–Krahe is KIPAC Fellow at the Kavli Institute of Particle Astrophysics and Cosmology, which is based at Stanford University. He is working within the X-ray Astronomy and Observational Cosmology Group. His research focuses on weak gravitational lensing and its applications for cosmology and astrophysics.
•CFHTLens •Euclid •The MAD Cluster Survey[1]
Working within the Leiden Observatory,he led a team of scientists[2] conducting an intensive study of over 446 000 galaxies within the COSMOS survey[3] field, the result of the largest survey ever conducted with Hubble,showing independent confirmation that the expansion of the Universe is accelerated by an additional, mysterious component named dark energy. A handful of other such independent confirmations exist.[4][5]
