SUMMARY:Leiden Spring 2020
DESCRIPTION:Leiden\, April 6th. \nThis meeting will take place via remote connection. Here the information for connecting: \nTime: Apr 3\, 2020 02:00 PM Amsterdam \nJoin Zoom Meeting\nZoom Link\nMeeting ID: 147 651 918\nPassword: 782828 \n \n14:00 – 14:30: Talk by Otto Akseli Hannuksela (Nikhef) \nTitle:Gravitational-wave lensing within ground-based gravitational-wave detectors \nAbstract: \nGravitational waves\, like light\, could be gravitationally lensed. Recent studies suggest that we might see gravitational wave lensing already within the coming decade. I will discuss some of the latest advances in gravitational wave lensing\, and present our search results for gravitational wave lensing within observation runs one and two. \n14:40 – 15:10 Talk by Fabrizio Renzi (Leiden University) \nTitle:Testing Background Cosmology with Future Strong Lensing Surveys \nAbstract: \nMeasurements of time delays between the images of multiply lensed quasars have been recently confirmed to be a competitive cosmological probe. Future surveys will increase the number of observed systems of at least an order of magnitude making strong lensing an interesting avenue to test the assumptions on the cosmological background. I will discuss the forecasted constraints from future strong lensing surveys on the parameterization of the backround at low redshift and how these are affected by the modeling of the lens mass profile. \n15:20 – 15:50: Talk by Shahab Joudaki(Oxford University) \nTitle: Cosmology from overlapping imaging and spectroscopic surveys \n \nAbstract: \n I will discuss the combined analysis of weak lensing tomography and overlapping redshift-space galaxy clustering from the Kilo Degree Survey (KiDS) and the spectroscopic surveys of 2dFLenS\, BOSS\, and GAMA\, with a focus on improvements to systematics mitigation and parameter constraints in standard and extended cosmologies. I will compare these parameter constraints to those obtained from the Dark Energy Survey (DES) and the Hyper Suprime-Cam (HSC) Survey\, and will assess their concordance with the Planck cosmic microwave background. In the case of KiDS and DES\, I will also discuss the improvements that result from a combined analysis of the two datasets.
