Multiwavelength Atlas of Galaxies

The images originate from a variety of telescopes, instruments and detectors, and therefore possess wide ranges of signal-to-noise, angular resolution, sampling or pixel sizes and fields of view.

The atlas is a compendium of galaxy images spanning the Gamma ray, X-ray, Ultraviolet, Optical, Infrared, Submillimeter and Radio regions of the electromagnetic spectrum.

The atlas has been favourably reviewed in the Royal Astronomical Society journal, Astronomy & Geophysics.

[3] Background on the genesis of the atlas can be found in an interview with the author in the Swinburne University of Technology Venture magazine.

[5] Explanatory text describes how different radiation is produced, which objects (i.e. cold, warm or hot gas, dust, stars, particles, atoms and molecules) it originates from, and what types of telescopes are used to detect it.

Starburst galaxies undergo intense star formation that is well in excess of normal rates.

Large numbers of young stars (O and B spectral type) exist and the dust content can be extremely high.

Active galaxies typically have strong emission over a large portion of the electromagnetic spectrum making them prime targets for multiwavelength observations.

These observations have utilized telescopes at ground-based observatories (many located at high altitude mountain sites), telescopes in aircraft (≥10 km altitude), detectors on balloons that voyaged to the upper atmosphere (30–40 km altitude), instrument payloads on rockets that reached space, observatory satellites in Earth and Solar orbit as well as instruments aboard planetary missions journeying through the Solar System.

The exceptions, NGC 2915 (Blue Compact Dwarf, BCD, Meurer, Mackie and Carignan 1994); the Galaxy (Sbc/SBbc, de Vaucouleurs 1970); Malin 2 (Low Surface Brightness, LSB, McGaugh and Bothun 1994) are indicated with types given in [ ].

Distance: In Mpc from Tully (1988), except for the Galaxy (Mezger et al. 1996); LMC (50 kpc.

Optical image of NGC 5194/M 51. Obtained by HST/ACS/WFC in F435W, F555W, F658N, F814W.
Centaurus A (NGC 5128 in the table below; Centaurus A is the radio source) is a nearby galaxy that contains a supermassive black hole actively powering a jet. A prominent X-ray jet extending for 13,000 light years points to the upper left in the image, with a shorter "counterjet" aimed in the opposite direction. In this image, low-energy X-rays are colored red, intermediate-energy X-rays are green, and the highest-energy X-rays detected by Chandra are blue. The dark green and blue bands running almost perpendicular to the jet are dust lanes that absorb X-rays.
