Iron emission line from the spiral galaxy M 101 [PDF]
Abstract Archival Suzaku data of the face-on spiral galaxy M 101 were analyzed. An intense emission line at 6.72$^{+0.10}_{-0.12}\:$keV was detected in the central region. This line is identified with a K-line from He-like iron, which indicates the existence of a thin thermal plasma with a temperature of several keV.

Emission-line Diagnostics at z > 4: [O iii]λ4364/Hγ versus [Ne iii]λ3870/[O ii]λ3730
We use JWST Near-Infrared Spectrograph observations from the Cosmic Evolution Early Release survey, GLASS-JWST ERS (GLASS), and JWST Advanced Deep Extragalactic Survey to measure rest-frame optical emission-line ratios of 89 galaxies at z > 4.

The Origin of [O II] Emission in Recently Quenched Active Galaxy Nucleus Hosts [PDF]
We have employed emission-line diagnostics derived from DEIMOS and NIRSPEC spectroscopy to determine the origin of the [O II] emission line observed in six active galactic nucleus (AGN) hosts at z ~ 0.9.

Shining a Light on the Connections between Galactic Outflows Seen in Absorption and Emission Lines
Galactic outflows provide important feedback effects to regulate the evolution of host galaxies. Two primary diagnostics of outflows are broad and/or blueshifted emission and absorption lines.
