A New Member of the Fast and Furious Family: A Relativistic and Time-Variable UV Outflow in a Luminous Quasar
Lucas M. Seaton, Patrick B. Hall, Liliana Flores +20
We report the fastest quasar outflow first detected in the ultraviolet, via variable C IV and Si IV absorption at outflow velocities km s to at least km…
SDSS-V LVM: Verifying what, and where, the 'Galactic Center' Lobe is
K. Kreckel, O. V. Egorov, N. Drory +23
The so-called 'Galactic Center' Lobe (GCL) is an extended (~1 deg) radio continuum feature situated above the Galactic Plane, for which the literature contains varying claims about…
4MOST ChANGES: Catalog of high-redshift quasar candidates (4.5 < < 7) selected with SED fitting
T. Mkrtchyan, C. Mazzucchelli, R. J. Assef +12
The identification of high-redshift quasars () is critical for studying the early Universe, supermassive black hole growth, and cosmic reionization. Most known high-redshi…
Unveiling large-scale rotational motions in the intragroup medium at z~1 through gravitational-arc tomography
Cédric Ledoux, Fernanda Muñoz-Olivares, L. Felipe Barrientos +8
We present the first spatially resolved characterisation of the cool intragroup medium (IGrM) in a spectroscopically confirmed galaxy group at z=1.167. Using 30 independent sightli…
Torus feeding and outflow launching in the active nucleus of the Circinus galaxy
Wout M. Goesaert, Konrad R. W. Tristram, C. M. Violette Impellizzeri +4
Context: Most active galactic nuclei (AGN) are believed to be surrounded by a dusty molecular torus on the parsec scale which is often embedded within a larger circumnuclear disk (…
