ALMA unveils a triple merger and gas exchange in a hyper-luminous radio galaxy at z=2: the Dragonfly Galaxy (II)
B. H. C. Emonts, C. De Breuck, M. D. Lehnert +9
The Dragonfly Galaxy (MRC0152-209), at redshift z~2, is one of the most vigorously star-forming radio galaxies in the Universe. What triggered its activity? We present ALMA Cycle 2…
VLT-FORS2 optical imaging and spectroscopy of 9 luminous type 2 AGN at 0.3<z<0.6: I. Ionized gas nebulae
A. Humphrey, M. Villar-Martín, C. Ramos Almeida +4
We present optical imaging and long slit spectroscopic observations of 9 luminous type 2 AGNs within the redshift range 0.3<z<0.6 based on VLT-FORS2 data. Most objects (6/9) are hi…
GTC optical imaging of extremely red 5C radio galaxies at high redshift
A. Humphrey, M. Villar-Martín, P. Lagos
We investigate the nature of seven unusual radio galaxies from the 5C catalogue that were previously known to have extremely red R-K colours, and for which emission lines were prev…
Witnessing the transformation of a quasar host galaxy at z=1.6
A. Humphrey, N. Roche, J. M. Gomes +9
A significant minority of high redshift radio galaxy (HzRG) candidates show extremely red broad band colours and remain undetected in emission lines after optical `discovery' spect…
