We report new K-band, radio continuum, and CO (1-0) imaging observations and 850 μm photometric observations of PDS 456, the most luminous QSO in the local universe (z < 0.3). The 0.″6 resolution K-band image obtained using the Keck Telescope shows three compact mK ~ 16.5 (MK ~ -21) sources at a projected distance of ~10 kpc to the southwest, and the host galaxy of PDS 456 may be interacting or merging with one or more companions. Observations using the Owens Valley Radio Observatory millimeter… 

A New Twist to an Old Story: HE 0450–2958 and the ULIRG → Optically Bright QSO Transition Hypothesis

We report on interferometric imaging of the CO J = 1–0 and J = 3–2 line emission from the controversial QSO/galaxy pair HE 0450–2958. The detected CO J = 1–0 line emission is found associated with

The gentle monster PDS 456

We report on the first ALMA observation of the CO(3−2) and rest-frame ∼340 GHz continuum emission in PDS 456, which is the most luminous, radio-quiet QSO in the local Universe (z ≃ 0.18), with a

A radio structure resolved at the deca-parsec scale in the radio-quiet quasar PDS 456 with an extremely powerful X-ray outflow

Active galactic nuclei (AGNs) accreting at rates close to the Eddington limit can host radiatively driven mildly relativistic outflows. Some of these X-ray absorbing but powerful outflows can produce

This is a report of Chandra, XMM-Newton, Hubble Space Telescope, and Astrophysical Research Consortium telescope observations of an extended X-ray source at z = 0.59. The apparent member galaxies

The nearby extreme accretion and feedback system PDS 456: finding a complex radio-emitting nucleus

When a black hole accretes close to the Eddington limit, the astrophysical jet is often accompanied by radiatively driven, wide-aperture and mildly relativistic winds. Powerful winds can produce
