▁The ▁purpose ▁of ▁the ▁at las ▁is ▁to ▁display ▁and ▁describe ▁some ▁of ▁the ▁best ▁multi w avel ength ▁images ▁of ▁galaxies . ▁The ▁images ▁origin ate ▁from ▁a ▁variety ▁of ▁teles cop es , ▁instruments ▁and ▁detect ors , ▁and ▁therefore ▁possess ▁wide ▁ranges ▁of ▁signal - to - no ise , ▁angular ▁resolution , ▁sampling ▁or ▁pixel ▁sizes ▁and ▁fields ▁of ▁view . ▁The ▁at las ▁is ▁a ▁comp end ium ▁of ▁galax y ▁images ▁sp anning ▁the ▁G amma ▁ray , ▁X - ray , ▁Ult rav io let , ▁Opt ical , ▁Inf ra red , ▁Sub mill imeter ▁and ▁Radio ▁regions ▁of ▁the ▁elect romagnet ic ▁spectrum . ▁ ▁The ▁at las ▁has ▁been ▁fav ou rab ly ▁review ed ▁in ▁the ▁Royal ▁Astronom ical ▁Society ▁journal , ▁Astronom y ▁& ▁Ge oph ys ics . ▁Creating ▁the ▁at las ▁was ▁a ▁long ▁term ▁project ▁ ▁ten ▁years ▁in ▁the ▁making . ▁Background ▁on ▁the ▁gen esis ▁of ▁the ▁at las ▁can ▁be ▁found ▁in ▁an ▁interview ▁with ▁the ▁author ▁in ▁the ▁Sw in bur ne ▁University ▁of ▁Technology ▁Vent ure ▁magazine . ▁It ▁is ▁recommended ▁for ▁gradu ate ▁students ▁and ▁above . ▁ ▁Ex plan atory ▁text ▁describes ▁how ▁different ▁radiation ▁is ▁produced , ▁which ▁objects ▁( i . e . ▁cold , ▁warm ▁or ▁hot ▁gas , ▁dust , ▁stars , ▁particles , ▁atoms ▁and ▁mole cules ) ▁it ▁origin ates ▁from , ▁and ▁what ▁types ▁of ▁teles cop es ▁are ▁used ▁to ▁detect ▁it .
