Strong X-ray Variability of I Zwicky 1: Obscuration from Clumpy Accretion-Disk Winds
Jian Huang, Bin Luo, W. N. Brandt +2
Obscuration from clumpy accretion-disk winds has been invoked to explain the extreme X-ray weakness and X-ray variability observed in a substantial fraction of super-Eddington accr…
Tracing Star Formation in Quasar Hosts via [O II] 3727: A Kinematically Consistent Approach
Liang Wu, Jun-Xian Wang, Luis C. Ho +2
Measuring star formation in quasar host galaxies is crucial for understanding the coevolution of supermassive black holes (SMBHs) and galaxies, yet remains observationally challeng…
Hot, Photoionized X-ray Gas in Two Luminous Type 2 Quasars: Chandra-HST Evidence for a Wind-Driven Sequence
Anna Trindade Falcão, S. Kraemer, L. Feuillet +17
We present new Chandra/ACIS-S imaging spectroscopy of two luminous type 2 quasars, FIRST J120041.4+314745 (=0.116) and 2MASX J13003807+5454367 (=0.088), and compare their X-r…
Spatially resolved broad line region in a quasar at z=4: Dynamical black hole mass and prominent outflow
GRAVITY+ Collaboration, K. Abd El Dayem, N. Aimar +92
We present the first near-infrared interferometric data of a QSO at z=4. The K-band observations were performed with GRAVITY+ on the VLTI using all four UTs, detecting a differenti…
Estimating Masses of Supermassive Black Holes in Active Galactic Nuclei from the Halpha Emission Line
E. Dalla BontÃ, B. M. Peterson, C. J. Grier +19
The goal of this project is to construct an estimator for the masses of supermassive black holes in active galactic nuclei (AGNs) based on the broad Halpha emission line. We make u…
Hubble Space Telescope Observations of Nearby Type 1 Quasars. I. Characterisation of the Extended [O III] 5007Ã Emission
Anna Trindade Falcão, S. B. Kraemer, T. C. Fischer +13
We use the Hubble Space Telescope to analyse the extended [O III] 5007A emission in seven bright radio-quiet type 1 quasars (QSO1s), focusing on the morphology and physical conditi…
