Narrow line AGN selection in CEERS: spectroscopic selection, physical properties, X-ray and radio analysis

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Giovanni Mazzolari, Jan Scholtz, Roberto Maiolino, Roberto Gilli, Alberto Traina | Summary: 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 identified 52 […]

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Jeffrey D. McKaig, Shobita Satyapal, Ari Laor, Nicholas P. Abel, Sara M. Doan | Summary: Forbidden collisionally excited optical atomic transitions from high ionization potential (IP$geq$54.8,eV) ions, such as Ca$^{mathrm{4+}}$, Ne$^{mathrm{4+}}$, Fe$^{mathrm{6+}}$, Fe$^{mathrm{10+}}$, Fe$^{mathrm{13+}}$, Ar$^{mathrm{9+}}$, and S$^{mathrm{11+}}$, are known as optical coronal lines (CLs). The spectral energy […]

Axion Dark Matter eXperiment around 3.3 μeV with Dine-Fischler-Srednicki-Zhitnitsky Discovery Ability

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: C. Bartram, C. Boutan, T. Braine, J. H. Buckley, T. J. Caligiure | Summary: We report the results of a QCD axion dark matter search with discovery ability for Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) axions using an axion haloscope. Sub-Kelvin noise temperatures are reached with an ultra low-noise Josephson parametric […]
