Thermal Structure and Chemical Enrichment of the North and South Polar Spurs: Supersolar N/O and Ne/O in the X-Ray Plasma

The Astrophysical Journal
The North Polar Spur (NPS) is a prominent diffuse X-ray feature whose origin has remained uncertain for decades. Using a uniform analysis of archival Suzaku and XMM-Newton data with new Chandra observations, we constrain its thermal and chemical ...

A Framework for Ultralow Surface-brightness Integral-field-unit Emission Mapping with the Keck Cosmic Web Imager

The Astronomical Journal
Detecting spatially resolved emission at surface-brightness levels of ∼10 ^−20 –10 ^−19  erg cm ^−2  s ^−1  arcsec ^−2  Å ^−1 in optical integral-field spectroscopy requires reduction procedures limited not by photon statistics, but by systematic effects

The Detection Rate of Associated Mg ii Absorption Lines in Quasars Depends on Their Radio Emission

The Astrophysical Journal
In active galactic nuclei, jet-driven feedback plays a significant role in influencing the properties of gas within their host galaxy and the circumgalactic medium.

The Two-component Circumgalactic Medium Emission around z ∼ 2 Radio-loud Quasars

The Astrophysical Journal
We present Ly α , He ii , and C iv observations of seven z ∼ 2 radio-loud quasars observed using the Keck Cosmic Web Imager and compare it to observed radio jet emission using archival Very Large Array and Atacama Large Millimeter/submillimeter Array ...
