Lucky Imaging combined with a low order adaptive optics system has given the highest resolution images ever taken in the visible or near infrared of faint...

A sample of active galaxies and quasars was observed with a photon-counting detector (IPCS) working in time-resolved imaging mode. The observing and data...

Nuclear rings in barred spiral galaxies offer an opportunity to study starburst properties, as well as the evolution of star formation in the central regions of...

We analyze Atacama Large Millimeter Array (ALMA) observations of the CO(6-5) molecular line and the 432 μm continuum emission from the circumnuclear disk (CND)...

The circumnuclear regions of some barred galaxies show strong bursts of star formation organized into miniature spiral arms or rings. Recent work has shown the...

The first results of a program of observations designed to probe the structure and kinematics of the Local Interstellar Medium (LISM) using the Queen's...

Luminous and Ultra-luminous IR galaxies ((U)LIRGs) are critical for investigating feedback mechanisms due to a combination of intense star formation (SF)...

Sunrise is a solar telescope with an aperture of 1 m, and is dedicated for spectropolarimetric measurements in the visible and the near UV. The total wavelength...

Sunrise is a 1m balloon-borne solar telescope. It is equipped with a spectrograph polarimeter which combines vector-polarimetry in the visible with diagnostic...
