Dust contribution to the panchromatic galaxy emission
Dian P. Triani, Darren J. Croton, Manodeep Sinha +3
We have developed a pipeline called \mentari to generate the far-ultraviolet to far-infrared spectral energy distribution (SED) of galaxies from the \dustysage semi-analytic galaxy…
Exploring the relation between dust mass and galaxy properties using Dusty SAGE
Dian P. Triani, Manodeep Sinha, Darren J. Croton +2
We explore the relation between dust and several fundamental properties of simulated galaxies using the Dusty SAGE semi-analytic model. In addition to tracing the standard galaxy p…
Dust masses, compositions, and luminosities in the nuclear disks and the diffuse circumnuclear medium of Arp220
Eli Dwek, Richard G. Arendt
We present an analysis of the 4-2600 m spectral energy distributions (SEDs) of the west and east nuclei and the diffuse infrared (IR) region of the merger-driven starburst Arp 2…
The origin of dust in galaxies across cosmic time
Dian P. Triani, Manodeep Sinha, Darren J. Croton +2
We study the dust evolution in galaxies by implementing a detailed dust prescription in the SAGE semi-analytical model for galaxy formation. The new model, called Dusty SAGE, follo…
Dust formation in AGN winds
Arkaprabha Sarangi, Eli Dwek, Demos Kazanas
Infrared observations of active galactic nucleus (AGN) reveal emission from the putative dusty circumnuclear 'torus' invoked by AGN unification, that is heated up by radiation from…
2 mm GISMO Observations of the Galactic Center. II. A Nonthermal Filament in the Radio Arc and Compact Sources
Johannes Staguhn, Richard G. Arendt, Eli Dwek +5
We have used the Goddard IRAM 2-Millimeter Observer (GISMO) with the 30 m IRAM telescope to carry out a 2 mm survey of the Galaxy's central molecular zone (CMZ). These observations…
