Mg-Zn co-doped GaN films were deposited by radio-frequency magnetron sputtering in an N2-Ar2 environment at room temperature, using a target prepared with Mg-Zn co-doped GaN powders. X-ray diffraction patterns showed broad peaks with an average cryst

We present a comprehensive X-ray analysis and spectral energy distribution (SED) fitting of WISEA J171419.96+602724.6, an extremely luminous type 2 quasar at z = 2.99. The source was suggested as a candidate Compton-thick (column density N _H > 1.5×

Spitzer spectral maps reveal a disk of highly luminous, warm (>150 K) H _2 in the center of the massive spiral galaxy Messier 58, which hosts a radio-loud active galactic nucleus (AGN). The inner 2.6 kpc of the galaxy appears to be overrun by shocks

In this work, we spectroscopically select narrow-line AGN (NLAGN) among the $\sim 300$ publicly available medium-resolution spectra of the CEERS Survey. Using both traditional and newly identified emission line NLAGN diagnostics diagrams, we identifi
