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).

Radio emission in star-forming galaxies: connection to restarted or relic AGN activity
Astronomy & AstrophysicsIncreasing evidence shows that active galactic nuclei (AGNs) with radio detections have more perturbed ionized gas kinematics and higher outflow detection rates, suggesting a link between radio emission and these processes.

Radio galaxies with and without emission lines
Proceedings of the International Astronomical Union, 2019 AbstractUsing the recent ROGUE I catalogue of galaxies with radio cores (Kozie_l-Wierzbowska et al. 2020) and after selecting the objects which are truly radio active galactic nuclei, AGNs, (which more than doubles the samples available so far), we perform a thorough comparison of the properties of radio galaxies with and without optical emission lines

Observations of the 57Fe+23 hyperfine transition in clusters of galaxies
, 1997 We present a search for the hyperfine transition of the 57Fe+23 ion at 3.071 mm in clusters of galaxies with the ATNF Mopra telescope. The results are compared with a realistic estimate of the peak brightness temperature of the line in a cooling flow ...

The [CII] 158 μm line emission in high-redshift galaxies
, 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.

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 ...
