Gravitational Lensing Magnification without Multiple Imaging
Gravitational lensing can amplify the apparent brightness of distant sources. For most lensing geometries, images that are significantly magnified are part of multiply-imaged systems, but that need not always be the case. We consider the extent to which lensing can produce large magnifications without creating more than one detectable image. One possibility is that lensing produces a single ima...
متن کاملGravitational Lensing Magnification and Time Delay Statistics for Distant Supernovae
Strong gravitational lensing of distant supernovae (SNe), particularly Type Ia’s, has some exploitable properties not available when other sorts of cosmologically distant sources are lensed. One such property is that the “standard candle” nature of SN at peak brightness allows a direct determination of the lensing magnification factor for each well observed image. Another is that the duration o...
متن کاملMagnification relations in gravitational lensing via multidimensional residue integrals
Gravitational lensing has proven to be not only important astrophysically, but intriguing mathematically as well. Mathematical investigations of gravitational lens theory have yielded important results and insights, employing techniques and results from such disparate areas as catastrophe theory, differential geometry and Morse theory. In this paper, we illustrate how another seemingly unrelate...
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 کاملCorrelation between Galaxies and Qso in the Sdss: a Signal from Gravitational Lensing Magnification?
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 < 19.1) at zQ ≃ 1.6. We find significant positive correlation in all cases except for the faintest QSOs, as expected if ...
