Reverberation Mapping of the Seyfert 1 Galaxy NGC 7469
B. M. Peterson, C. J. Grier, Keith Horne +43
A large reverberation mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for Hbeta 4861 and He II 4686 and a central black hole mass measurement of about…
Discovery of eight z ~ 6 quasars from Pan-STARRS1
E. Bañados, B. P. Venemans, E. Morganson +24
High-redshift quasars are currently the only probes of the growth of supermassive black holes and potential tracers of structure evolution at early cosmic time. Here we present our…
AGN Type-casting: Mrk 590 No Longer Fits the Role
K. D. Denney, G. De Rosa, K. Croxall +9
We present multi-wavelength observations that trace more than 40 years in the life of the active galactic nucleus (AGN) in Mrk 590, traditionally known as a classic Seyfert 1 galax…
Spectral Energy Distributions of QSOs at z>5: common AGN-heated dust and occasionally strong star-formation
C. Leipski, K. Meisenheimer, F. Walter +7
We present spectral energy distributions (SEDs) of 69 QSOs at z>5, covering a rest frame wavelength range of 0.1mu to ~80mu, and centered on new Spitzer and Herschel observations.…
