A large H survey of star formation in relaxed and merging galaxy cluster environments at
Andra Stroe, David Sobral, Ana Afonso +4
We present the first results from the largest H survey of star formation and AGN activity in galaxy clusters. Using 9 different narrow band filters, we select H emitt…
The growth of typical star-forming galaxies and their super massive black holes across cosmic time since z~2
João Calhau, David Sobral, Andra Stroe +5
Understanding galaxy formation and evolution requires studying the interplay between the growth of galaxies and the growth of their black holes across cosmic time. Here we explore…
The nature of H-alpha star-forming galaxies at z~0.4 in and around Cl 0939+4713: the environment matters
David Sobral, Andra Stroe, Yusei Koyama +5
Cluster star-forming galaxies are found to have an excess of Far-Infrared emission relative to H-alpha (Ha), when compared to those in the field, which could be caused by intense A…
The most luminous H emitters at z~0.8-2.23 from HiZELS: evolution of AGN and star-forming galaxies
David Sobral, Saul A. Kohn, Philip N. Best +5
We use new near-infrared spectroscopic observations to investigate the nature and evolution of the most luminous Hα(Ha) emitters at z~0.8-2.23, which evolve strongly in number dens…
