H i Properties of Field Galaxies at z ≈ 0.2–0.6: Insights into Declining Cosmic Star Formation
The Astrophysical Journal LettersWe report statistically significant detection of H i 21 cm emission from intermediate-redshift ( z ≈ 0.2–0.6) galaxies. By leveraging multisightline galaxy survey data from the Cosmic Ultraviolet Baryon Survey and deep radio observations from the ...

Spatially resolved spectroscopy of Coma Cluster early‐type galaxies. IV. Completing the data set [PDF]
, 2008 The long-slit spectra obtained along the minor axis, offset major axis, and diagonal axis are presented for 12 E and S0 galaxies of the Coma Cluster drawn from a magnitude-limited sample studied before.

A Catalog of Broad Hα and Hβ Active Galactic Nuclei in MaNGA
The Astrophysical JournalBroad H α and H β emission lines (FWHM > 1000 km s ^−1 ) are incredibly efficient tracers of the high-velocity clouds encircling active galactic nuclei (AGNs).

The [CII] 158 μm line emission in high-redshift galaxies [PDF]
, 2018 International audienceGas is a crucial component of galaxies, providing the fuel to form stars, and it is impossible to understand the evolution of galaxies without knowing their gas properties.

Probing cosmic voids with emission-line galaxies
Frontiers in Astronomy and Space SciencesIntroductionWe aim to provide forecasts for future line intensity mapping (LIM) observations and galaxy redshift surveys, focusing on the physical properties of low-density region of the cosmic web (voids).

Extended Emission Lines in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1982 In whatever physical state the gas is found, observations of the interstellar medium in elliptical galaxies are of considerable interest. This is particularly true in the case of radio galaxies where we believe that the gas is an indespensable part of the cause of nuclear activity and plays a role in the origin and the evolution of the radio galaxy ...

The Astrophysical JournalWe searched the Chandra and XMM archives for 900 Green Pea galaxies to identify signs of active galactic nuclei (AGN). Green peas are low-mass, emission-line galaxies that resemble high-redshift dwarf galaxies. From 29 observations, we detected X-rays in
