In this paper we present new near infrared (NIR) imaging and spectroscopic data of the quasar 3C 48 and its host galaxy. The data were obtained with the ESO-VLT camera ISAAC. We report the first detection of the apparent second nucleus 3C 48A about 1 '' NE of the bright QSO nucleus in the NIR bands J, H, and K s. 3C 48A is highly reddened with respect to the host, which could be due to warm dust, heated by enhanced star formation or by interstellar material intercepting the rad io jet. In fact… Expand
Near infrared imaging of the broad absorption line quasar BAL QSO 0134+3253
In this paper we present near infrared (NIR) imaging data of the host galaxy of the broad absorption line quasar (BALQ) at $z=2.169$, serendipitously found close to 3C 48 (Canalizo et al. 1998, AJ,Expand
The Nature of Optical Features in the Inner Region of the 3C 48 Host Galaxy
The well-known quasar 3C 48 is the most powerful compact steep-spectrum radio-loud QSO at low redshifts. It also has two unusual optical features within the radius of the radio jet (~1''): (1) anExpand
Molecular gas and continuum emission in 3C 48: evidence for two merger nuclei?
Received ; accepted Abstract. We present new interferometer observations of the CO(1-0) line and mm continuum emission from 3C48 — one of the nearest examples of a merger activating a quasar. Our newExpand
A high-angular resolution study of the nuclear regions of quasar host galaxies with the NaCo simultaneous differential imager
A project aiming at the study of the emission line gas morphology in quasar host galaxies by means of adaptive-optics-assisted simultaneous narrow-band imaging of the line and continuum emission isExpand
The radio counter-jet of the QSO 3C 48
We present multi- frequency radio observational results of the quasar 3C 48. The observations were carried out with the Very Large Array ( VLA) at five frequencies, 0.33, 1.5, 4.8, 8.4, and 22.5 GHz,Expand
Kinematics of the parsec-scale radio jet in 3C 48
We present results on the compact steep-spectrum quasar 3C 48 from observations with the Very Long Baseline Array (VLBA), the Multi-Element Radio Linked Interferometer Network (MERLIN) and theExpand
The QSO Hosts I Zw 1 and 3C 48: Prototypes of a Merger-Driven Quasar Evolution?
I Zw 1 and 3C 48 are two neighboring template objects at a later stage of the hypothesized merger-driven evolutionary sequence from ultra-luminous infrared galaxies (ULIRGs) to quasi-stellar objectsExpand

Merger driven ULIRG–QSO evolution: The case of 3C 48
Abstract The QSO 3C 48 and its host galaxy constitute a nearby template object of the proposed merger-driven evolutionary sequence from ULIRGs to QSOs. In this contribution multi-wavelengthExpand
