Dust attenuation in NGC7793

Dust can greatly alter the light emitted by galaxies, causing galaxies to become redder and dimmer. The different tracers that we can use to estimate the fundamental physical properties of galaxies are affected by this, making dust a mayor and direct impediment to our attempts to understand the formation and evolution of galaxies. To overcome this, major efforts have been undertaken to develop new methods to correct the panchromatic emission of galaxies for the presence of dust. Key to this is the attenuation (and extinction) curve. Unfortunately, in recent years evidence has been accumulating that attenuation curves may not be as universal as we once thought, with variations not only between but also within galaxies. However it still remains unclear what drives the variation of attenuation curves. In this work we will leverage the state-of-the-art CIGALE modeling code to characterize the attenuation law of NGC 7793 and its variation within the galaxy by combining multi-wavelength broadband data from the UV to FIR, with hydrogen lines observed with MUSE
