ALMA CO(1-0) data for IRAS 13120−5453. Top left: moment-zero map. Overplotted are contours for outflow in the range [−690, −270] km s−1 (blue) and [270, 510] km s−1 (red), with contours at [0.55, 0.9, 1.2] mJy beam−1. Top right: spectrum in a r = 1″ aperture centered on the continuum nucleus. The spectrum is decomposed into six Gaussians, four for the double-horned host line profile and two for outflow (green). The black line includes all six Gaussian components. The source hosts a strong outflow component. Center left: center positions and their errors, from UV fitting a Gaussian model to individual velocity channels. Center and bottom right: position-velocity diagrams, along the line core velocity gradient at PA ∼90° and orthogonal to it.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
