OpenNGC is a database containing positions and main data of NGC (New General Catalogue) and IC (Index Catalogue) objects. It has been built by merging data from NED, HyperLEDA,...

We present a 9deg^2^ map of the North American and Pelican Nebulae regions obtained in all four Infrared Array Camera (IRAC) channels with the Spitzer Space Telescope. The...

We present results from three deep ROSAT high-resolution imager observations of the Orion Nebula star-forming region. The X-ray images contain over 1500 catalogued stars in a...

We have analyzed archival Einstein Observatory images of a roughly 4.5 square degree region centered on the Orion Nebula. In all, 245 distinct X-ray sources have been detected...

We describe an automatic, objective routine for analyzing the clumpy structure in a spectral line position-position-velocity data cube. The algorithm works by first contouring...

We study the kinematics of emission lines that arise from many physical processes in NGC6153 based upon deep, spatially resolved, high-resolution spectra acquired with the UVES...

We have investigated a broad range of evidence concerning rotation in molecular clouds. As a consequence, we show that trends in specific angular momentum J/M and angular...

Circumgalactic Ly{alpha} nebulae are gaseous halos around galaxies exhibiting luminous extended Ly{alpha} emission. This work investigates Ly{alpha} nebulae from deep imaging of...

The Catalogue of Bright Nebulae lists the galactic and equatorial coordinates of the center of the cloud, the dimensions of the nebulae as measured on the photograph on which it...

This catalog is an updated version from the published version. The catalog was based on the red and blue prints of the National Geographic - Palomar Observatory Sky Atlas. The...

(adapted from Anne C. Raugh, NASA STI-T-1-5810-508-86) The catalog is a compilation of data gleened from a study of the European Southern Observatory Quick Blue Survey (ESO(b))...

Long exposures of the complexes of ionized hydrogen in both the LMC and SMC have been taken with the 48-in. SRC Schmidt camera through an H{alpha}+[N II] interference filter to...

The Catalog of bright diffuse Galactic nebulae was compiled in the frame of a thesis investigating the spatial distribution and the geometrical properties of bright diffuse...

A survey of the Milky Way southward of the Palomar Sky Survey for the identification of reflection nebulae was carried out at the Cerro Tololo Inter-American Observatory in...

The Catalogue of Rodgers, Cambell, and Whiteoak (RCW), was the result of a survey of emission nebulae carried out at Mt. Stromlo Observatory from December 1957 to April 1959....

A catalogue is given of all BD and CD stars north of -33deg which are surrounded by reflection nebulosity visible on both the blue and red prints of the Palomar Sky Survey. The...

The catalogue describes the position, maximum angular diameters, classifications according to form, structure and brightness, and the number of associated stars. The acronym...

(no description available) Cone search capability for table VII/191/table1 (The catalogue of Southern Dark Clouds (DCld))

Photoelectric and spectroscopic observations of the protoplanetary object V1853 Cyg, a B supergiant with an IR excess, are given. The observations were carried out with a UBV...
