We present first results from James Webb Space Telescope (JWST) Near-Infrared Spectrograph (NIRSpec), Mid-Infrared Instrument (MIRI), and Keck Cosmic Imager (KCWI) integral field spectroscopy of the powerful but highly obscured host-galaxy jetted radio source Cygnus A. detect 169 infrared emission lines at 1.7--27 micron explore kinematics physical properties extended narrow-line region (NLR) in unprecedented detail. The density-stratified NLR appears to be shaped by initial blow-out ongoing...
Abstract We present a case study of HE 0040-1105, an unobscured radio-quiet active galactic nucleus (AGN) at high accretion rate λ Edd = 0.19 ± 0.04. This particular AGN hosts ionized gas outflow with the largest spatial offset from its compared to all other AGNs in Close Reference Survey. By combining multiwavelength observations Very Large Telescope/MUSE, Hubble Space Telescope/Wide Field Camera 3, Array, and European VLBI Network, we probe ionization conditions, kinematics, radio emission...
Abstract With two central galaxies engaged in a major merger and remarkable chain of 19 young stellar superclusters wound around them projection, the galaxy cluster SDSS J1531+3414 ( z = 0.335) offers an excellent laboratory to study interplay between mergers, active galactic nucleus (AGN) feedback, star formation. New Chandra X-ray imaging reveals rapidly cooling hot T ∼ 10 6 K) intracluster gas, with “wings” forming concave density discontinuity near edge cool core. LOFAR 144 MHz...
We present a case study of HE 0040-1105, an unobscured radio-quiet AGN at high accretion rate (Eddington ratio = 0.19+/-0.04). This particular hosts ionized gas outflow with the largest spatial offset from its nucleus compared to all other AGNs in Close Reference Survey (CARS). By combining multi-wavelength observations VLT/MUSE, HST/WFC3, VLA, and EVN we probe ionization conditions, kinematics, radio emission host galaxy scales central few pc. detect four kinematically distinct components,...
With two central galaxies engaged in a major merger and remarkable chain of 19 young stellar superclusters wound around them projection, the galaxy cluster SDSS J1531+3414 ($z=0.335$) offers an excellent laboratory to study interplay between mergers, AGN feedback, star formation. New Chandra X-ray imaging reveals rapidly cooling hot ($T\sim 10^6$ K) intracluster gas, with "wings" forming concave density discontinuity near edge cool core. LOFAR $144$ MHz observations uncover diffuse radio...
