Low-temperature UV photoluminescence of ion beam synthesized Si nanoclusters embedded in Si

This article explores Ultraviolet (UV) photoluminescence (PL) data taken on a double Au implanted Si matrix and studied over a wide temperature range of 28-220K. The results of this study at lower temperatures indicate the emission to be coming from Si nanoclusters (NCs) embedded in the matrix.

An Extreme X-Ray Variability Event of a Weak-line Quasar (open access)

An Extreme X-Ray Variability Event of a Weak-line Quasar

Article reports the discovery of an extreme X-ray flux rise (by a factor of ≳20) of the weak-line quasar Sloan Digital Sky Survey (SDSS) J153913.47+395423.4 (hereafter SDSS J1539+3954) at z = 1.935. SDSS J1539+3954 is the most-luminous object among radio-quiet type 1 active galactic nuclei (AGNs) where such dramatic X-ray variability has been observed.
