TL;DR
The SwiM_v4.1 catalog combines Swift/UVOT NUV imaging with MaNGA optical spectroscopy for 559 nearby galaxies, enabling detailed studies of star formation and dust attenuation with a larger, more diverse sample than previous versions.
Contribution
This paper introduces SwiM_v4.1, a significantly expanded and unbiased catalog that integrates UV and optical data for nearby galaxies, facilitating advanced astrophysical analyses.
Findings
Expanded sample size to 559 galaxies.
Provides uniform data products for multi-wavelength analysis.
Enables studies of quenching, attenuation, and black hole feedback.
Abstract
We present the the new Swift/UVOT+MaNGA (SwiM) catalog (SwiM_v4.1). SwiM_v4.1 is designed to study star-formation and dust attenuation within nearby galaxies given the unique overlap of Swift/UVOT near-ultraviolet (NUV) imaging and MaNGA integral field optical spectroscopy. SwiM_v4.1 comprises 559 objects, ~4 times more than the original SwiM catalog (SwiM_v3.1), spans a redshift range z~0.0002-0.1482, and provides a more diverse and rich sample. Approximately 5% of the final MaNGA sample is included in SwiM_v4.1, and 42% of the SwiM_v4.1 galaxies are cross-listed with other well-known catalogs. We present the same data as SwiM_v3.1, including UVOT images, SDSS images and MaNGA emission-line and spectral index maps with the same pixel size and angular resolution for each galaxy, and a file containing galaxy and observational properties. We designed SwiM_v4.1 to be unbiased, which…
