Triplets of Quasars at high redshift I: Photometric data
M. Victoria Alonso, Georgina V. Coldwell, Ilona Sochting +4
We have conducted an optical and infrared imaging in the neighbourhoods of 4 triplets of quasars. R, z', J and Ks images were obtained with MOSAIC II and ISPI at Cerro Tololo Inter…
The VSOP 5 GHz Active Galactic Nucleus Survey: V. Imaging Results for the Remaining 140 sources
R. Dodson, E. B. Fomalont, K. Wiik +21
In February 1997, the Japanese radio astronomy satellite HALCA was launched to provide the space-bourne element for the VLBI Space Observatory Programme (VSOP) mission. Approximate…
AGNs and galaxy interactions
M. Sol Alonso, Diego G. Lambas, Patricia Tissera +1
We perform a statistical analysis of AGN host characteristics and nuclear activity for AGNs in pairs and without companions. Our study concerns a sample of AGNs derived from the SD…
Properties of galaxies in SDSS Quasar environments at z < 0.2
Georgina V. Coldwell, Diego G. Lambas
We analyse the environment of low redshift, z < 0.2, SDSS quasars using the spectral and photometric information of galaxies from the Sloan Digital Sky Survey Third Data Release (S…
Effects of galaxy interactions in different environments
M. Sol Alonso, Diego G. Lambas, Patricia B. Tissera +1
We analyse star formation rates derived from photometric and spectroscopic data of galaxies in pairs in different environments using the 2dF Galaxy Redshift Survey (2dFGRS) and the…
The VSOP 5 GHz AGN Survey: III. Imaging Results for the First 102 Sources
W. K. Scott, E. B. Fomalont, S. Horiuchi +17
The VSOP mission is a Japanese-led project to study radio sources with sub-milliarcsec resolution using an orbiting 8 m telescope, HALCA, along with global arrays of Earth-based te…
