Abstract |
The main goal of this thesis is to estimate of the luminosity of the CO(J=7-6) line
and to calculate molecular gas mass of the Hot Dust-Obscured Galaxy (Hot DOG) WISE
J224607.57-052635.0 (W2246-0526 hereafter). Hot DOGs are an uncommon population
of hyper-luminous, substantially dust-obscured quasars detected by the NASA’s W ide −
f ield Infrared Survey Explorer (W ISE) mission. Observations from Atacama Large
Millimeter/Submillimeter Array (ALMA) Observatory were used. The Common Astronomy Software Applications (CASA) software was used to produce the data cube of the
emission line from the ALMA interferometric observations. Astropy was used for the later
analysis. As presented in the section 3, we first estimated the flux of the CO(J=7-6) line,
and then calculated its luminosity. Using scaling relations from the literature, the luminosity
of CO(1-0) was derived. Finally, using an αCO conversion factor appropriate for our source
the molecular gas mass of the host galaxy was obtained.
