The impact of selection criteria on the properties of green valley galaxies
Beatrice Nyiransengiyumva, Mirjana Povic, Pheneas Nkundabakura +2
Context: The bi-modality in the distribution of galaxies usually obtained from colour-colour or colour-stellar mass diagrams has been studied to show the difference between the gal…
The [OIII] profiles of far-infrared active and non-active optically-selected green valley galaxies
Antoine Mahoro, Petri Väisänen, Mirjana Pović +8
We present a study of the line profile in a sub-sample of 8 active galactic nuclei (AGN) and 6 non-AGN in the optically-selected green valley at $\rm{z\,<\,0.5…
Stellar populations of a sample of far-IR AGN and non-AGN green valley galaxies
Antoine Mahoro, Mirjana Pović, Petri Väisänen +2
We present a study on the stellar populations and stellar ages of sub-sample of far-infrared AGN and non-AGN green valley analysed in Mahoro et al. (2017,2019) at 0.6 < z < 1.0 usi…
Properties of green valley galaxies in relation to their selection criteria
Beatrice Nyiransengiyumva, Mirjana Povic, Pheneas Nkundabakura +1
The distribution of galaxies has been studied to show the difference between the blue cloud and red sequence and to define the green valley region. However, there are still many op…
Properties of X-ray detected far-IR AGN in the green valley
Antoine Mahoro, Mirjana Pović, Petri Väisänen +3
In this study, we analysed active galactic nuclei in the "green valley" by comparing active and non-active galaxies using data from the COSMOS field. We found that most of our X-ra…
Star formation in far-IR AGN and non-AGN galaxies in the green valley. II. Morphological analysis
Antoine Mahoro, Mirjana Pović, Pheneas Nkundabakura +2
This paper studies morphological properties of 103 green valley FIR active and 2609 non-active galaxies presented in Mahoro et al. 2017. The photometric data from the COSMOS survey…
