Optical Spectropolarimetry of Broad Line Active Galaxies
(Astronomical Society of the Pacific, 1999)
We present new optical spectropolarimetry of two bright type 1 AGNs. The observations are part of a project on broad line active galaxies in which, through data analysis and modelling, we aim to identify the polarization ...
Monitoring the Ha Line in BL Lacertae - Evidence for an Accretion Disk
(Astronomical Society of the Pacific, 1999)
We present new spectroscopic observations of the recently discovered broad Ha line in BL Lacertae. These data, obtained over a period of 30 months, indicate that the line equivalent width is anti-correlated with the continuum ...
A Seyfert Nucleus in BL Lacertae
(Astronomical Society of the Pacific, 1999)
We have obtained spectroscopic observations of the broad Ha line in BL Lacertae over a period of 30 months. These data show that the line equivalent width is anti-correlated with the continuum flux implying that the broad ...
