Studies of Galaxies Far, Far Away….

Studies of deep space reveal interesting information all of the time!  This evening, I was watching a program on The Science Channel which delved into details regarding galactic studies.  The scientists whom were interviewed provided their knowledge of studies into far away galaxies.

The information given was about Ultra-Luminous Infrared Galaxies (ULIRGs).  These are galactic structures which emit their energy in infrared wavelengths.  ULIRGS are distant, which gives facts about their ages and lumious outputs.  Additonally,  They are more luminous than LIRGs, and less luminous than HLIRGs.

ULIRGS produce over 1,012 values of luminosity, measured in far-infrared wavelengths.  This indicates that these galactic structures contain excess amounts of matter, specifically referring to extreme accumulations of dust.  The high amounts of dust show that these galaxies are active with matter used to form stars.

The actual source of these galaxies’ power is not fully understood.  This is often hidden by cosmic dust that is visible at near-infrared, optical, and ultraviolet wavelengths.  It is generally recognized that the power source of ULIRGs is blocked by the cosmic dust that is visible within these wavelengths.

These types of galaxies are not as prevalent today as they were in the past.  They are believed to have been an intregal part of the formation of the recognized universe, and they are not as prevalent now as they were during the past.  Instruments such as The Spitzer Space Telescope are being used to study ULIRGs in an effort to assess their parts in the formations of galaxies, and indeed how the universe itself came into being!
