E = mc**2 without relativity
TL;DR: The equivalence of mass and energy is indelibly linked with relativity, both by scientists and in the popular mind as mentioned in this paper, and it has been proven that E = mc^2 by demanding momentum conservation of an object that emits two equal electromagnetic wave packets in opposite directions in its own frame.

TL;DR: The analysis of OGLE-2015-BLG-0196 microlensing event is presented in this article, where the light curve exhibited significant deviations from the lensing model based on the rectilinear lens-source relative motion, enabling to measure the microlens parallax.
Journal ArticleDOI
A survey for large image-separation lensed quasars
TL;DR: In this paper, the authors extend the results of the HST Snapshot Survey for Lensed Quasars to the 7''-50'' range for a sub-sample of 76 quasars that is free of known selection effects.
Journal ArticleDOI
Microlens Parallaxes with SIRTF
Andrew Gould,Andrew Gould +1 more
TL;DR: In this article, the parallax asymmetry between the Earth and the satellite is measured using the delay between the time the event peaks at the satellite and the Earth's positions.
