Interferometric detections of GOODS 850-5 at 1 mm and 1.4 GHz
H. Dannerbauer, F. Walter, G. Morrison
We have obtained a position (at sub-arcsecond accuracy) of the submillimeter bright source GOODS 850-5 (also known as GN10) in the GOODS North field using the IRAM Plateau de Bure…
Molecular gas in QSO host galaxies at z>5
R. Maiolino, R. Neri, A. Beelen +10
We present observations with the IRAM Plateau de Bure Interferometer of three QSOs at z>5 aimed at detecting molecular gas in their host galaxies as traced by CO transitions. CO (5…
High resolution CO imaging of high redshift QSO host galaxies
F. Walter, D. A. Riechers, C. L. Carilli +3
We review recent high-resolution CO observations of distant QSOs obtained at the Very Large Array. The aim of these observations is to resolve the molecular gas distribution in the…
The Star Formation Threshold in NGC 6822
WJG de Blok, F Walter
We investigate the star formation threshold in NGC 6822, a nearby Local Group dwarf galaxy, on sub-kpc scales using high-resolution, wide-field, deep HI, Halpha and optical data. I…
Multiple CO lines in SMM J16359+6612 -- Further evidence for a merger
A. Weiss, D. Downes, F. Walter +1
Using the IRAM 30m telescope, we report the detection of the CO(3--2), CO(4--3), CO(5--4) and CO(6--5) lines in the gravitational lensed submm galaxy SMM J16359+6612 at z=2.5. The…
The Spectral Energy Distribution of CO lines in M82
A. Weiss, F. Walter, N. Z. Scoville
We present an analysis of the excitation conditions of the molecular gas in the streamers and the outflow of M82 based on observations obtained at the IRAM 30m telescope. Our analy…
