Clash: Joint Analysis of Strong-lensing, Weak-lensing Shear, and Magnification Data for 20 Galaxy Clusters
We present a comprehensive analysis of strong-lensing, weak-lensing shear and magnification data for a sample of 16 X-ray-regular and 4 high-magnification galaxy clusters at 0.19 < ∼ z < ∼ 0.69 selected from the Cluster Lensing And Supernova survey with Hubble (CLASH). Our analysis combines constraints from 16-band Hubble Space Telescope observations and wide-field multi-color imaging taken pri...
متن کاملWeak lensing reconstruction through cosmic magnification – I. A minimal variance map reconstruction
We present a concept study on weak lensing map reconstruction through the cosmic magnification effect in galaxy number density distribution. We propose a minimal variance linear estimator to minimize both the dominant systematic and statistical errors in the map reconstruction. It utilizes the distinctively different flux dependences to separate the cosmic magnification signal from the overwhel...
متن کاملDetection of Weak Gravitational Lensing Magnification from Galaxy-qso Cross-correlation in the Sdss
We report a detection of galaxy-QSO cross-correlation wGQ in the Sloan Digital Sky Survey (SDSS) Early Data Release (EDR) over 0.2−30 arc-minute scales. We cross-correlate galaxy samples of different mean depths r = 19 − 22 (zG = 0.15 − 0.35) with the main QSO population (i′Q < 19.2) at zQ ≃ 1.6. We find positive detection in most cases (except for the faintest QSOs, as expected) with up to 8-s...
متن کاملHigh magnification chromoscopic colonoscopy as a screening tool in acromegaly
We read with great interest the paper by Jenkins et al (Gut 2002;51:V13–14) regarding screening guidelines for colorectal cancer (CRC) and polyps in patients with acromegaly and the subsequent discussion by Renehan addressing screening inconsistencies compared with other high risk groups. 2 The optimal colorectal screening modality and frequency in this group however requires clarification. Col...
متن کاملWeak Lensing
In the preceding chapters, the effects of lensing were so strong as to leave an unmistakable imprint on a specific source, allowing a detailed treatment. However, only the densest regions of the universe are able to provide such a spectacular lensing effect. To study more representative regions of the universe, we must examine large numbers of sources statistically. This is the domain of weak l...
