  2. 1. Molecular observations of obscured galaxy nuclei

    Author : Niklas Falstad; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxies: nuclei; Galaxies: ISM; Infrared: galaxies; ISM: Molecules; Submillimeter: galaxies;

    Abstract : It is becoming evident that some (ultra)luminous infrared galaxies ((U)LIRGs) contain compact obscured nuclei (CONs) where luminosities in excess of 10^9 L☉  emerge from inside dusty regions smaller than 100 pc in diameter. Due to the obscured nature of these objects, their inner regions are hidden from examination using optical or infrared lines. READ MORE

  4. 2. Water and hydroxyl in luminous infrared galaxies: Spectroscopic observations and modelling

    Author : Niklas Falstad; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ISM: molecules; Galaxies: individual: Zw 049.057; Line: formation; Galaxies: ISM; Submillimeter: galaxies; Infrared: galaxies;

    Abstract : Many luminous infrared galaxies (LIRGs) contain compact obscured nuclei (CONs) where luminosities in excess of 10^9 Lsun emerge from inside dusty regions smaller than 100 pc in diameter. Due to the obscuring material in these regions, the nature of the nuclear power source cannot be determined using direct observations in the optical or IR. READ MORE
