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 the 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, Sloan Digital Sky Survey (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
resulted in some objects having low signal-to-noise ratios in their
MaNGA or Swift data. We addressed this by providing a new file
containing the fraction of science-ready pixels in each MaNGA
emission-line map, and the integrated flux and inverse variance for
all three NUV filters. The uniform angular resolution and sampling in
SwiM_v4.1 will help answer a number of scientific questions, including
constraining quenching and attenuation in the local Universe and
studying the effects of black hole feedback. The galaxy maps, catalog
files, and their associated data models are publicly released on the
SDSS website.
Description:
The new SwiM catalog, SwiM_v4.1, includes a subset of galaxies in the
MaNGA survey, which is an IFU spectroscopic survey included in the
fourth generation of SDSS (SDSS-IV). We used the MaNGA Product Launch
11 (MPL-11), which is the last data release, is presented in SDSS-IV
Data Release 17 (i.e., SDSS-DR17; Abdurro'uf+ 2022, III/286), and
includes 10145 galaxies.
The MaNGA spectroscopic observations were obtained with hexagonal IFU
fiber bundles mounted on the 2.5m Sloan Foundation Telescope, and fed
into the dual-channel Baryon Oscillation Spectroscopic Survey (BOSS)
spectrographs. The spectra span a total wavelength range from 3622 to
10350Å at a spectral resolution of R∼2000.
The Swift/UVOT is a 30cm telescope, with a field of view (FOV) of
17'x17' and an effective plate scale of 1"/pixel.
See Section 2.1.
In order to define the SwiM_v4.1 sample, we crossmatched the MPL-11
catalog with the UVOT data archive hosted by the High Energy
Astrophysics Science Archive Research Center (HEASARC) as of 2021-Aug,
and required that each object was observed with both the uvw1 and uvw2
NUV filters. Of the 10145 MPL-11 galaxies, 570 met these initial
constraints. In addition to the final 546 objects selected with
archival data, we performed dedicated Swift/UVOT observations of a
further 13 galaxies. The new observations were taken between 2020 May
and 2021 January as part of the GI program 1619136 (PI: M. Molina). We
summarize the new observations in Table 2. See Section 2.2.
We assume a ΛCDM cosmology when quoting physical properties
such as masses, distances, and luminosities, with Ωm=0.3,
Λ=0.7, and H0=70km/s/Mpc.
