VizieR Online Data Catalog: ALMaQUEST. IV. ALMA-MaNGA QUEnching & star formation (Lin+, 2020)

MaNGA is an Integral Field Spectroscopy (IFS) survey conducted with the loan Digital Sky Survey (SDSS) 2.5m telescope. MaNGA uses the BOSS spectrographs and couples them with hexagonal fiber bundles of different sizes. Each spectrum covers a wavelength range of 3500-10000Å with a spectral resolution ~60km/s. After dithering, MaNGA data have an effective angular resolution (FWHM) of 2.5", corresponding to a physical scale of 0.5-6.5kpc.

Molecular gas observations in 12CO(1-0) (rest-frame 115.271204GHz) were carried out with ALMA during Cycles 3, 5, and 6 using the Band 3 receiver. The observations were taken in the C43-2 configuration (synthesized beam FWHM ~2.5"), thus matching the MaNGA resolution. We used a single pointing with a field of view (FOV) of ~50". The largest structure that we expect to be sensitive to is about 23" (~14kpc). Our spectral setup includes one high-resolution spectral window (~10km/s) targeting 12CO(1-0) and one to three low-resolution spectral window(s) (~90km/s) around the target line aimed at detecting/studying the continuum.
