Prospects and Pitfalls of Gravitational Lensing in Large Supernova Surveys
Aims. To investigate the effect of gravitational lensing of supernovae in large ongoing surveys. Methods. We simulate the effect of gravitational lensing magnification on individual supernovae using observational data input from two large supernova surveys. To estimate the magnification due to matter in the foreground, we simulate galaxy catalogs and compute the magnification along individual l...
متن کاملNeutrino gravitational lensing
We study the lensing of neutrinos by astrophysical objects. At the difference of photons, neutrinos can cross a stellar core; as a result the lens quality improves. While Uranians alone would benefit from this effect in the Sun, similar effects could be considered for binary systems. Chercheur I. I. S. N. Directeur de recherches du F. N. R. S.
متن کاملGravitational Lensing of the Most Distant Known Super - nova , SN 1997
We investigate the effect of gravitational lensing on the farthest known supernova, SN1997ff. The SN was found at z ∼ 1.7 in the Hubble Deep Field North and is most likely of Type Ia. Due to our poor knowledge of the properties of the lensing foreground galaxies, we conclude that large magnification effects are possible for reasonable lens parameter values implying that this single SN does not ...
متن کاملTesting the principle of equivalence by supernova neutrinos
We study the possible impact of the neutrino oscillation which could be induced by a tiny violation of equivalence principle (VEP) for neutrinos emitted from supernova driven by gravitational collapse. Due to the absence of any significant indication of neutrino oscillation in the SN1987A data, we obtain sever bounds on relevant VEP parameters δγ ∼ O(10−31) for massless or degenerated neutrinos...
متن کاملDetection of neutrinos from supernovae in nearby galaxies.
While existing detectors would see a burst of many neutrinos from a Milky Way supernova, the supernova rate is only a few per century. As an alternative, we propose the detection of approximately 1 neutrino per supernova from galaxies within 10 Mpc, in which there were at least 9 core-collapse supernovae since 2002. With a future 1 Mton scale detector, this could be a faster method for measurin...
