Towards an observationally motivated AGN dusty torus model -- II. The roles of density distribution and chemical composition of the dust
Omar Ulises Reyes-Amador, Omaira González-Martín, Jacopo Fritz +5
Several models of nuclear dust in active galactic nuclei (AGN) have been presented in the literature to determine its physical and geometrical properties, usually assuming the dust…
JWST MIRI and NIRCam observations of NGC 891 and its circumgalactic medium
Jérémy Chastenet, Ilse De Looze, Monica Relaño +37
We present new JWST observations of the nearby, prototypical edge-on, spiral galaxy NGC 891. The northern half of the disk was observed with NIRCam in its F150W and F277W filters.…
Towards an observationally motivated AGN dusty torus model. I. Dust chemical composition from the modeling of Spitzer spectra
Omar Ulises Reyes-Amador, Jacopo Fritz, Omaira González-Martín +7
Spectral energy distribution (SED) fitting is one of most commonly used techniques to study the dust properties in Active Galactic Nuclei (AGN). Works implementing this technique c…
The TNG50-SKIRT Atlas: wavelength dependence of the effective radius
Maarten Baes, Aleksandr Mosenkov, Raymond Kelly +17
Galaxy sizes correlate with many other important properties of galaxies, and the cosmic evolution of galaxy sizes is an important observational diagnostic for constraining galaxy e…
The TNG50-SKIRT Atlas: post-processing methodology and first data release
Maarten Baes, Andrea Gebek, Ana Trcka +17
Galaxy morphology is a powerful diagnostic to assess the realism of cosmological hydrodynamical simulations. Determining the morphology of simulated galaxies requires the generatio…
The role of grain size in AGN torus dust models
Omaira González-Martín, Cristina Ramos Almeida, Jacopo Fritz +10
Fits the infrared spectra from the nuclear regions of AGN can place constraints on the dust properties, distribution, and geometry by comparison with models. However, none of the c…
