Extreme Gaseous Outflows in Radio-Loud Narrow-Line Seyfert 1 Galaxies
S. Komossa, D. W. Xu, A. Y. Wagner
We present four radio-loud NLS1 galaxies with extreme emission-line shifts, indicating radial outflow velocities of the ionized gas of up to 2450 km/s, above the escape velocity of…

A Global Photoionization Response to Prompt Emission and Outliers: Different Origin of Long Gamma-ray Bursts?
J. Wang, L. P. Xin, Y. L. Qiu +2
By using the line ratio \ion{C}{4}/\ion{C}{2} as a tracer of ionization ratio of the interstellar medium (ISM) illuminated by a long gamma-ray burst (LGRB…
