[2307.07641] 5-12 pc resolution ALMA imaging of gas and dust in the obscured compact nucleus of IRAS 17578-0400
View PDFAbstract:We here present 0.02-0.04'' resolution ALMA observation of the compact obscured nucleus (CON) of IRAS17578-0400. A dusty torus within the nucleus, approximately 4 pc in radius, has been uncovered, exhibiting a usually flat spectral index at ALMA band 3, likely due to the millimeter corona emission from the central supermas...
