Tracking Outflow using Line-Locking (TOLL). I. The case study of Quasar J221531-174408
Chen Chen, Weimin Yi, Zhicheng He +2
Investigating line-locked phenomena within quasars is crucial for understanding the dynamics of quasar outflows, the role of radiation pressure in astrophysical flows, and the star…
First results from the JWST Early Release Science Program Q3D: The Fast Outflow in a Red Quasar at z=0.44
Weizhe Liu, Sylvain Veilleux, Swetha Sankar +26
Quasar feedback may play a key role in the evolution of massive galaxies. The dust-reddened quasar, F2M110648.35480712 at is one of the few cases at its redshift th…
Fast Outflows and Luminous He II Emission in Dwarf Galaxies with AGN
Weizhe Liu, Sylvain Veilleux, Gabriela Canalizo +6
While stellar processes are believed to be the main source of feedback in dwarf galaxies, the accumulating discoveries of AGN in dwarf galaxies over recent years arouse the interes…
[OIII] 5007 emissions in extremely red quasars (ERQs) are compact
Marie Wingyee Lau, Serena Perrotta, Fred Hamann +5
``Extremely red quasars'' (ERQs) are a non-radio-selected, intrinsically luminous population of quasars at cosmic noon selected by their extremely red colour from rest-frame UV to…
High Resolution Spectra of Quasar AALs: 3C 191
Frederick W. Hamann, T. A. Barlow, F. C. Chaffee +2
We discuss new high-resolution (6.7 km/s) spectra of the associated absorption lines (AALs) in the radio-loud quasar 3C 191. The measured AALs have ionizations ranging from Mg I to…
Discovery of a 2 Kpc Binary Quasar
G. A. Shields, V. Junkkarinen, E. A. Beaver +4
LBQS 01032753 is a binary quasar with a separation of only 0.3 arcsec. The projected spacing of 2.3 kpc at the distance of the source (z = 0.848) is much smaller than that of an…
LBQS 0103-2753: A 0.3 Arcsec Binary Quasar
V. Junkkarinen, G. A. Shields, E. A. Beaver +4
Imaging and spectroscopy with HST show that LBQS 0103-2753 (V = 17.8, z = 0.848) is a binary quasar with a separation of 0.3 arcsec or 2.3 kpc. This is by far the smallest separati…
High-Resolution Keck Spectra of the Associated Absorption Lines in 3C 191
Frederick W. Hamann, T. A. Barlow, F. C. Chaffee +2
Associated absorption lines (AALs) are valuable probes of the gaseous environments near quasars. Here we discuss high-resolution (6.7 km/s) spectra of the AALs in the radio-loud qu…
