We have detected four giant molecular cloud associations (sizes ≤6.″6 ≈ 430 pc) in the western and eastern regions of the polar ring in NGC 2685 (the Helix galaxy) using the Owens Valley Radio Observatory millimeter interferometer. Emission from molecular gas is found close to the brightest Hα and H I peaks in the polar ring and is confirmed by new IRAM 30 m single-dish observations. The CO and H I line velocities are very similar, providing additional kinematic confirmation that the CO… 

Molecular content of polar-ring galaxies

We have searched for CO lines in a sample of 21 new morphologically determined polar-ring galaxies (of which nine are kinematically confirmed), obtained from a wide search in the Galaxy Zoo proj ect

Molecular gas and star formation in early-type galaxies

We present new mm interferometric and optical integral-field unit (IFU) observations and construct a sample of 12 elliptical (E) and lenticular (S0) galaxies with molecular gas which have both CO and

Neutral hydrogen in nearby elliptical and lenticular galaxies: the continuing formation of early-type galaxies

We present the results of deep Westerbork Synthesis Radio Telescope observations of neutral hydrogen in 12 nearby elliptical and lenticular galaxi es. The selected objects come from a representative

The molecular polar disc in NGC 2768

We present CO(1-0) and CO(2-1) maps of the molecular polar disc in the elliptical galaxy NGC 2768 obtained at the Institute de Radioastronomie Millimetrique (IRAM) Plateau de Bure Interferometer. The

Molecular gas and star formation in the SAURON early-type galaxies

We present the results of a survey of CO emission in 43 of the 48 representative E/S0 galaxies observed in the optical with the SAURON integral-field spectrograph. The CO detection rate is 12/43 or

The ATLAS3D project - X. On the origin of the molecular and ionized gas in early-type galaxies

We make use of interferometric CO and HI observations, and optical integral-field spectroscopy from the ATLAS 3D survey to probe the origin of the molecular and ionised interstellar medium (ISM) in

Kinematic modeling of disk galaxies - III. The warped “Spindle” NGC 2685

This is the third of a series of papers in which the structure and kinematics of disk galaxies is studied. By employing direct tilted-ring fits to the data cube as introduced in Paper I, we analyzed

The ATLAS3D project - XIV. The extent and kinematics of the molecular gas in early-type galaxies

We use interferometric (CO)-C-12(1-0) observations to compare and contrast the extent, surface brightness profiles and kinematics of the molecular gas in CO-rich ATLAS(3D) early-type galaxies (ETGs)

The outskirts of galaxies offer extreme environments where we can test our understanding of the formation, evolution, and destruc tion of molecules and their relationship with star formation and

The Stellar Content of the Polar Rings in the Galaxies NGC 2685 and NGC 4650A

We present the results of stellar photometry of polar ring galaxies NGC 2685 and NGC 4650A, using the archival data obtained with the Hubble Space Telescope's Wide Field Planetary Camera 2. Polar

CO emission from the polar-ring S0 galaxy NGC 2685 and origin of the ring structure

A CO emission line has been detected in the polar-ring S0 galaxy NGC 2685 and the possible origin of the circumnuclear molecular gas is discussed. It is suggested that the gas has been fed by the

H II Region Abundances in the Polar Ring of NGC 2685

We have obtained optical spectrophotometry of 11 H II regions in the polar ring of NGC 2685 (the Helix galaxy) and have used these data to study the physical characteristics of the polar-ring H II

Detection of CO J = 2 goes to 1 emission from the polar rings of NGC 2685 and NGC 4650A

We report the detection of the J = 2 goes to 1 (230 GHz) line of carbon monoxide in the polar rings of the galaxies NGC 2685 and NGC 4650A, and we use the results in a simple analysis of the

A photometric and dynamical study of the Helix galaxy NGC 2685

We present optical and near-infrared surface photometry of the Helix galaxy NGC 2685 and its two rings. We detected the inner (polar) ring in the near-infrared J-band and found that its colors are
