CCAPP Seminar: "Weak Lensing with Current and Future Surveys"
Melanie Simet (UC Riverside)
Weak lensing is one of the cosmological probes considered to have the most power for upcoming large-scale photometric surveys. However, there are a number of systematic effects that must be considered when making these measurements. I will discuss some recent work in measuring galaxy cluster masses via weak lensing signals, an important measurement to facilitate the use of galaxy cluster abundances as a cosmological probe. I will also discuss efforts to understand galaxy blends, a systematic effect where some detections assumed to be single objects for lensing measurements are actually superpositions of galaxies at two different redshifts.
