Monitoring Mkn 279 in BVRI and H{beta} fluxes
Mid-infrared images of the Seyfert 1 galaxy Mrk 279 obtained with the ISO satellite are presented together with the results of a one-year monitoring campaign of the... -
Seyferts in galaxy pairs and groups
The occurrence of Seyfert galaxies in 6 samples representative of different cosmological environments (i.e. isolated pairs, compact and loose groups) is analysed. To avoid... -
Radio galaxies in the 2dFGRS
We use redshift determinations and spectral analysis of galaxies in the 2dF Galaxy Redshift Survey () to study the properties of local radio sources with S>=1mJy. 557 objects... -
Universidad Complutense de Madrid list 1
A low dispersion objective-prism survey for low-redshift emission-line galaxies (ELGs) is being carried out by the University Complutense de Madrid with the Schmidt telescope at... -
Properties of ICRF3 sources from SDSS spectra
Despite their importance for astrometry and navigation, the active galactic nuclei (AGNs) that comprise the International Celestial Reference Frame (ICRF) are relatively poorly... -
Iron template spectrum from Mrk493 HST/STIS obs.
We present a new empirical template for iron emission in active galactic nuclei (AGNs) covering the 4000-5600{AA} range. The new template is based on a spectrum of the...
