Local environmental dependence on weak-lensing shear statistics
Sonia Akter Ema, Md Rasel Hossen, Krzysztof Bolejko +1
Despite the assumption that an ideal FLRW observer is not dependent on the local environment, observations are biased by the positions of the observers due to the matter correlatio…
Ringing the universe with cosmic emptiness: void properties through a combined analysis of stacked weak gravitational and Doppler lensing
Md Rasel Hossen, Sonia Akter Ema, Krzysztof Bolejko +1
An essential aspect of cosmic voids is that these underdense regions provide complementary information about the properties of our Universe. Unlike dense regions, voids are avoided…
Mapping the cosmic mass distribution with stacked weak gravitational lensing and Doppler lensing
Md Rasel Hossen, Sonia Akter Ema, Krzysztof Bolejko +1
Dark matter halos represent the highest density peaks in the matter distribution. Conversely, cosmic voids are under-dense patches of the universe. Probing the mass distribution of…
The density distributions of cosmic structures: impact of the local environment on weak-lensing convergence
Sonia Akter Ema, Md Rasel Hossen, Krzysztof Bolejko +1
Whilst the underlying assumption of the Friedman-Lemaître-Robertson-Walker (FLRW) cosmological model is that matter is homogeneously distributed throughout the universe, gravitatio…
