VizieR Online Data Catalog: Light attenuation in star-forming regions (Molina+, 2020)
Abstract
This paper explores a subset of a larger sample that was chosen to study star formation and its quenching in the local Universe. Our approach is to simultaneously analyse the near-UV (NUV) stellar continuum and optical nebular emission lines across the faces of galaxies, using data that are well matched in depth and physical scale.
In order to simultaneously study NUV and optical properties, we cross-referenced the MaNGA Product Launch 7 (MPL-7), corresponding to the SDSS Data Release 15, or DR15 (Aguado et al. 2019ApJS..240...23A), with the Swift/UVOT NUV archive as of 2018 April 26. UVOT is a 30cm telescope that has a field of view (FOV) of 17arcminx17arcmin with an effective plate scale of 1arcsec/pixel. Since this project aims to study the NUV slope, we required that all objects in our sample have UVOT images in both the uvw1 and uvw2 filters. We place a secondary constraint on the X-ray emission, LX(2-10)keV~<1041erg/s, to exclude luminous active galactic nuclei (AGNs), using the Swift X-ray Telescope (XRT) point source catalogue (Evans et al. 2014ApJS..210....8E, Cat. IX/43). These requirements produce a sample of 139 galaxies. From the sample of 139 galaxies, we select 29 galaxies with SFRs appropriate for our study. (4 data files).- Publication:
