چکیده
A recent analysis of high angular resolution NIR imaging and spectroscopic data in conjunction with Plateau de Bure interferometric mm-line observations indicate the presence of a circum-nuclear starburst ring of ∼1.5” (1.5 kpc) diameter in I Zw 1. High angular resolution NIR imaging, using the MPE SHARP camera at the ESO NTT, HST V-band images, as well as NIR spectroscopy with MPE 3D provide an improved analysis of the star formation activity in the disk and nucleus of I Zw 1. We present first results from subarcsecond interferometric imaging in the CO(2-1) line using the Plateau de Bure Interferometer.

Received ; accepted – 2 – ABSTRACT We have investigated the ISM of the I Zw 1 QSO host galaxy with Plateau de Bure mm-interferometry and high angular resolution near-infrared imaging spectroscopy. We have detected a circumnuclear gas ring of diameter ∼ 1.5 " (1.8 kpc) in its millimetric CO line emission and have mapped the disk and the spiral arms of the host galaxy in the 12 CO(1-0) line at 11...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملThe Low Co Content of the Extremely Metal Poor Galaxy I Zw 18
We present sensitive molecular line observations of the metal-poor blue compact dwarf I Zw 18 obtained with the IRAM Plateau de Bure interferometer. These data constrain the CO J = 1 → 0 luminosity within our 300 pc (FWHM) beam to be LCO < 1×10 5 K km s pc (ICO < 1 K km s ), an order of magnitude lower than previous limits. Although I Zw 18 is starbursting, it has a CO luminosity similar to or ...
متن کاملStars & Gas in the Galaxy Pair IIZw 70/71
II Zw 71 (UGC 9562) was classified as a " probable " polar-ring galaxy in the Polar-Ring Catalog ((Whitmore et al. 1990)), based upon its optical appearance. We present 21 cm and optical observations of this galaxy and its companion, the blue star-forming dwarf II Zw 70. Our 21 cm observations show that 5 × 10 8 solar masses of H I is present in a polar ring orbiting II Zw 71, and show a spatia...
متن کاملStar formation in Blue Compact Dwarf Galaxies : Mkn 104 and I Zw 97
Two blue compact dwarf galaxies Mkn 104 and I Zw 97 are studied photometrically and spectroscopically. Mkn 104 is found to contain three distinct bright star forming regions, whereas I Zw 97 is found to contain three bright and two faint star forming regions. Medium resolution spectra of three bright H ii regions in the two galaxies were obtained. Estimation of oxygen abundance in these regions...
