A VLBA-resolved Jet Associated with Super-Eddington Accretion in a Radio-loud Quasar at
Sakiko Obuchi, Ingyin Zaw, Kazuhiro Hada +2
We report the detailed jet properties of eROSITA Final Equatorial Depth Survey (eFEDS) J084222.9+001000 (hereafter ID830), a radio-loud super-Eddington quasar at , reveal…
Discovery of an X-ray Luminous Radio-Loud Quasar at : A Possible Transitional Super-Eddington Phase
Sakiko Obuchi, Kohei Ichikawa, Satoshi Yamada +11
We report the multiwavelength properties of eFEDS J084222.9+001000 (hereafter ID830), a quasar at , identified as the most X-ray luminous radio-loud quasar in the eROSITA…
Dependence of the Radio Emission on the Eddington Ratio of Radio-Quiet Quasars
A. Alhosani, J. D. Gelfand, I. Zaw +4
Roughly 10% of quasars are "radio-loud", producing copious radio emission in large jets. The origin of the low-level radio emission seen from the remaining 90% of quasars is unclea…
A Uniformly Selected, Southern-Sky 6dF, Optical AGN Catalog
Yan-Ping Chen, Ingyin Zaw, Glennys R Farrar +1
We have constructed a catalog of active galactic nuclei (AGNs) with , based on optical spectroscopy, from the parent sample of galaxies in the 6dF galaxy survey (Final Re…
A search for HO masers in 100 active dwarf galaxies
M. J. Rosenthal, I. Zaw
We present the results of the first dedicated survey for 22 GHz HO maser emission in dwarf galaxies outside of the local group, with the aim of discovering disc masers. Studies…
An Accreting, Anomalously Low Mass Black Hole at the Center of Low Mass Galaxy IC 750
Ingyin Zaw, Michael J. Rosenthal, Ivan Yu. Katkov +5
We present a multi-wavelength study of the active galactic nucleus in the nearby ( Mpc) low mass galaxy IC 750, which has circumnuclear 22 GHz water maser emission. The mas…
