Emission-Line and Continuum Reverberation Mapping of the NLS1 Galaxy WPVS 48
M. A. Probst, W. Kollatschny, M. W. Ochmann +6
WPVS 48 is a nearby narrow-line Seyfert 1 galaxy without previous analysis of the broad-line region (BLR) by means of optical spectroscopic reverberation mapping. By studying the c…
Multiwavelength continuum, emission line and BAL variability with prominent PV absorption in the X-ray-weakest quasar PG0043+039
Wolfram Kollatschny, Norbert Schartel, Malte A. Probst +3
PG0043+039 has been identified as an extremely X-ray-weak quasar and as a peculiar broad-absorption-line quasar based on UV HST spectra. We took simultaneous deep X-ray observation…
Long Term Reverberation Mapping of Iron Coronal Lines in MKN 110
Charles Yin, Andy Lawrence, Martin Ward +2
We present flux measurements of the coronal lines [Fe VII] and [Fe X] spanning three decades, in the highly variable Active Galactic Nucleus (AGN) MKN 110. These coronal lines are…
Double-peaked Ca II traces a relativistic broad-line region disk in NGC 4593
M. W. Ochmann, P. M. Weilbacher, M. A. Probst +7
Double-peaked emission lines are observed in a small percentage of active galactic nuclei (AGN). These lines allow the determination of properties of the line-emitting region, know…
