Searches of stellar mass dark matter from an analysis of variabilities of high red-shifted QSOs
A. F. Zakharov, L. C. Popovic, P. Jovanovic
We consider a contribution of microlensing to the X-ray variability of high-redshifted QSOs. Such an effect could be caused by stellar mass objects (SMO) located in a bulge or/and…
