VLT/Magellan spectroscopy of 29 strong lensing selected galaxy clusters
Mauricio Carrasco, L. Felipe Barrientos, Timo Anguita +6
We present an extensive spectroscopic follow-up campaign of 29 strong lensing (SL) selected galaxy clusters discovered primarily in the Second Red-Sequence Cluster Survey (RCS-2).…
MiNDSTEp differential photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756: Microlensing and a new time delay
E. Giannini, R. W. Schmidt, J. Wambsganß +52
We present V and R photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756. The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope…
ALMA Spectroscopic Survey in the Hubble Ultra Deep Field: Search for [CII] line and dust emission in 6<z<8 galaxies
M. Aravena, R. Decarli, F. Walter +29
We present a search for [CII] line and dust continuum emission from optical dropout galaxies at using ASPECS, our ALMA Spectroscopic Survey in the Hubble Ultra-Deep Field (UD…
ALMA spectroscopic survey in the Hubble Ultra Deep Field: Continuum number counts, resolved 1.2-mm extragalactic background, and properties of the faintest dusty star forming galaxies
M. Aravena, R. Decarli, F. Walter +31
We present an analysis of a deep (1=13 Jy) cosmological 1.2-mm continuum map based on ASPECS, the ALMA Spectroscopic Survey in the Hubble Ultra Deep Field. In the 1 arcmin$^2…
The ALMA Frontier Fields survey I: 1.1 mm continuum detections in Abell 2744, MACSJ0416.1-2403 and MACSJ1149.5+2223
J. González-López, F. E. Bauer, C. Romero-Cañizales +21
Dusty star-forming galaxies are among the most prodigious systems at high redshift (z>1), characterized by high star formation rates and huge dust reservoirs. The bright end of thi…
The different origins of high- and low-ionization broad emission lines revealed by gravitational microlensing in the Einstein cross
Lorraine Braibant, Damien Hutsemékers, Dominique Sluse +1
We investigate the kinematics and ionization structure of the broad emission line region of the gravitationally lensed quasar QSO2237+0305 (the Einstein cross) using differential m…
