Disc galaxy resolved in HI absorption against the radio lobe of 3C 433: Case study for future surveys
Suma Murthy, Raffaella Morganti, Bjorn Emonts +3
The neutral atomic gas content of galaxies is usually studied in the HI 21cm emission line of hydrogen. However, at higher redshifts, we need very deep integrations to detect HI em…
Discovery of a giant and luminous Lya+CIV+HeII nebula at z=3.326 with extreme emission line ratios
R. Marques-Chaves, I. Pérez-Fournon, M. Villar-Martín +17
We present the discovery of HLock01-LAB, a luminous and large Lya nebula at z=3.326. Medium-band imaging and long-slit spectroscopic observations with the Gran Telescopio Canarias…
Properties of ionized outflows in MaNGA DR2 galaxies
Bruno Rodríguez del Pino, Santiago Arribas, Javier Piqueras-López +2
We present the results from a systematic search and characterization of ionized outflows in nearby galaxies using the data from the second Data Release of the MaNGA Survey (DR2; >…
Photoionization models for extreme Ly 1216 and HeII 1640 ratios in quasar halos, and PopIII vs AGN diagnostics
A. Humphrey, M. Villar-Martín, L. Binette +1
We explore mechanisms to produce extremely high Ly-alpha/HeII flux ratios, or to enhance the observed number of Ly-alpha photons per incident ionizing photon, in extended AGN-photo…
The MUSE 3D view of feedback in a high-metallicity radio galaxy at z = 2.9
M. Silva, A. Humphrey, P. Lagos +8
We present a detailed study of the kinematic, chemical and excitation properties of the giant Ly emitting nebula and the giant \ion{H}{I} absorber associated with the …
The spatially resolved stellar population and ionized gas properties in the merger LIRG NGC 2623
C. Cortijo-Ferrero, R. M. González Delgado, E. Pérez +10
We report on a detailed study of the stellar populations and ionized gas properties in the merger LIRG NGC 2623, analysing optical Integral Field Spectroscopy from the CALIFA surve…
An infrared view of AGN feedback in a type-2 quasar: the case of the Teacup galaxy
Cristina Ramos Almeida, Javier Piqueras López, Montserrat Villar-Martín +1
We present near-infrared integral field spectroscopy data obtained with VLT/SINFONI of "the Teacup galaxy". The nuclear K-band (1.95-2.45 micron) spectrum of this radio-quiet type-…
Ionization and feedback in Ly halos around two radio galaxies at z2.5
S. G. Morais, A. Humphrey, M. Villar-Martín +6
We present new spectroscopic observations of two high redshift radio galaxies, TXS 0211-122 (z=2.34) and TXS 0828+193 (z=2.57), known to be associated with large Ly halos. The o…
High-velocity extended molecular outflow in the star-formation dominated luminous infrared galaxy ESO 320-G030
M. Pereira-Santaella, L. Colina, S. García-Burillo +9
We analyze new high spatial resolution (~60 pc) ALMA CO(2-1) observations of the isolated luminous infrared galaxy ESO 320-G030 (d=48 Mpc) in combination with ancillary HST optical…
Sub-kpc star-formation law in the local luminous infrared galaxy IC 4687 as seen by ALMA
M. Pereira-Santaella, L. Colina, S. García-Burillo +8
We analyze the spatially resolved (250 pc scales) and integrated star-formation (SF) law in the local luminous infrared galaxy (LIRG) IC4687. This is one of the first studies of th…
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…
Resolving the optical emission lines of Lya blob 'B1' at z=2.38: another hidden quasar
