HI-MaNGA
HI (21cm) Followup of MaNGA Survey Galaxies using the Green Bank Telescope.
Summary
The goal of HI-MaNGA is to provide valuable information about the cold gas content of galaxies, which can help to address several of MaNGA’s key science questions: (1) How does gas accretion drive the growth of galaxies? (2) What are the relative roles of stellar accretion, major mergers, and instabilities in forming galactic bulges and ellipticals? (3) What quenches star formation? What external forces affect star formation in groups and clusters? (4) How was angular momentum distributed among baryonic and non-baryonic components as the galaxy formed, and how do various mass components assemble and influence one another?
Observations have been ongoing at the Green Bank Telescope since 2016, with over 2000 hours of observing time under codes 16A-095, 17A-012, 19A-127 and 20B-033.
Available Data
- DR1
- GBT observations of 331 galaxies
- Data can be found in an SDSS-IV DR16 VAC.
- Data descriptions in Masters et al. (2019)
- DR2
- GBT observations of 2135 galaxies
- ALFALFA (untargeted HI survey with Arecibo) crossmatch with 1714 galaxies
- Catalog description can be found Stark et al. (2021)
Due to an unknown reason, the HI spectra of 15 ALFALFA detections which are close to the edges of the ALFALFA footprint could not be extracted and are therefore not provided in HI-MaNGA DR2. These are plate-ifu=['8139-12702', '8139-12704', '8139-12705','8139-6101', '8438-12704', '8446-12701', '8554-12704', '8939-1902', '8943-12702', '8981-12705', '9049-3704', '9086-12701', '9192-6102', '9493-12702', '9866-6103']
