Similar galaxies have probably been classified as star forming in previous studies of dense clusters, possibly obscuring some of the effects of the cluster environment on true star-forming galaxies. | |
Our analysis reveals that UV-selected star-forming galaxies have a broad range of the formation redshift. | |
Such local C III] emitters may shed light on the conditions of star formation in certain extreme high-redshift galaxies. | |
16 Citations | Our results suggest that the environment helps to trigger the star formation in the highest mass galaxies. |
We show however that these observed trends, if real, can be due to the different micro-history of star formation in massive galaxies with respect to dwarf systems. | |
The prevalence of star-forming cluster members (galaxies with >1.5 M_☉ yr^(–1)) implies that this massive, high-redshift cluster is experiencing a phase of active star formation, and supports recent results showing a marked increase in star formation occurring in galaxy clusters at z ≳ 1.4. | |
Our results point toward early and rapid formation for a significant fraction of present-day massive galaxies. | |
Given our results only for two objects, they solely cannot constrain the evolutionary models, but provide us with interesting hints and set an observational path towards addressing the role of star formation and nuclear activity in forming galaxies. | |
Similar conclusions hold for the bright planetary nebulae in galaxies with ongoing star formation. | |
Our results show that all the galaxies appear to have experienced their most recent star formation episode less than 107 years ago, in good agreement with previous values found in the literature. | |
We estimate the star formation histories of these galaxies, which suggests that they have recently undergone an increase in their star formation rates. | |
As a function of morphology and environment, the behavior of the star formation efficiency within galaxies is consistent with the results of our previous investigation of the global quantities. | |
The results for the star formation rate agree with recent observational data on early-type galaxies. |
