Was SN 1997 ff at z ∼ 1 . 7 magnified by gravitational lensing ?
The quest for the cosmological parameters has come to fruition with the identification of a number of supernovae at a redshift of z ∼ 1. Analyses of the brightness of these standard candles reveal that the Universe is dominated by a large cosmological constant. The recent identification of the z ∼ 1.7 SN1997ff in the northern Hubble Deep Field has provided further evidence for this cosmology. H...

متن کاملLensing and high-z supernova surveys
Gravitational lensing causes the distribution of observed brightnesses of standard candles at a given redshift to be highly non-gaussian. The distribution is strongly, and asymmetrically, peaked at a value less than the expected value in a homogeneous Robertson-Walker universe. Therefore, given any small sample of observations in an inhomogeneous universe, the most likely observed luminosity is...
متن کاملGravitational lensing by gravitational waves
Gravitational lensing by gravitational wave is considered. We notice that although final and initial direction of photons coincide, displacement between final and initial trajectories occurs. This displacement is calculated analytically for the plane gravitational wave pulse. Estimations for observations are discussed.
متن کاملFirst case of strong gravitational lensing by a QSO: SDSS J0013+1523 at z = 0.120*
We present the first case of strong gravitational lensing by a QSO: SDSS J0013+1523 at z = 0.120. The discovery is the result of a systematic search for emission lines redshifted behind QSOs, among 22 298 spectra of the SDSS data release 7. Apart from the z = 0.120 spectral features of the foreground QSO, the spectrum of SDSS J0013+1523 also displays the [O ii] and Hβ emission lines and the [O ...
