Probabilistic Modelling for Delay Estimation in Gravitationally Lensed Photon Streams
We test whether a more principled treatment of delay estimation in lensed photon streams, compared with the standard kernel estimation method, can have benefits of more accurate (less biased) and/or more stable (less variance) estimation. To that end, we propose a delay estimation method in which a single latent inhomogeneous Poisson process underlying the lensed photon streams is imposed. The ...
متن کاملChandra Observations of the Gravitationally Lensed System 2016 + 112
An observation of the gravitationally lensed system 2016+112 with the Chandra X-ray Observatory has resolved a mystery regarding the proposed presence of a dark matter object in the lens plane of this system. The Chandra ACIS observation has clearly detected the lensed images of 2016+112 with positions in good agreement with those reported in the optical and also detects 13 additional X-ray sou...
متن کاملHelical Jet in the Gravitationally Lensed Blazar
Recent radio VLBI observations of the complex gravitationally lensed system PKS1830-211 have thrown up some questions with regard to the processes occuring at the heart of the blazar source at a redshift of 2.51, which is viewed almost straight down the jet axis. This work links, by a model of a helical jet tracked by ballistically ejected plasmons from a precessing nozzle, observations on the ...
متن کاملGravitationally Lensed Type – II Quasar
A single-screen model of the gravitational lens system 2016+112 is proposed, that explains recent Hubble Space Telescope (HST) infrared (NICMOS–F160W) observations and new high-resolution European VLBI Network (EVN) 5–GHz radio observations, presented in this paper. In particular, we find that a massive 'dark' structure at the lens position, previously suggested by X-ray, optical and spectrosco...
متن کاملTuning Gravitationally Lensed Standard Sirens
Gravitational waves emitted by chirping supermassive black hole binaries could in principle be used to obtain very accurate distance determinations. Provided they have an electromagnetic counterpart from which the redshift can be determined, these standard sirens could be used to build a high redshift Hubble diagram. Errors in the distance measurements will most likely be dominated by gravitati...
