VizieR Online Data Catalog: RESOLVE survey: 21cm obs. with GBT & Arecibo (Stark+, 2016)
Abstract
The REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey is a volume-limited census of galaxies in the local universe with the goal of accounting for baryonic and dark matter mass within a statistically complete subset of the z=0 galaxy population. A complete description of the survey design will be presented in S. J. Kannappan et al. (2016, in preparation).
This paper presents new 21cm observations, but an optical spectroscopic survey is under way, primarily with the SOAR 4.1m telescope, and also using SALT, Gemini, and the AAT. The blindly detected 21cm sources in the standard ALFALFA catalog (Giovanelli+ 2005AJ....130.2598G) are cross-matched with RESOLVE using a match radius of 2', corresponding to the spatial resolution of the final ALFALFA data cubes. Additionally, we search the ALFALFA data cubes at the positions of all galaxies that lack counterparts within the standard ALFALFA catalogs. To complete the RESOLVE HI census, new 21cm observations were carried out with the Robert C. Byrd New Green Bank Telescope (GBT, programs 11B-056, 13A-276, 13B-246, 14A-441) and Arecibo Observatory (programs a2671, a2812, a2852). GBT data were acquired over a total of 738hr between 2011 August and 2014 July. Arecibo data were acquired over a total of 554hr in 2012 March and again between 2013 July and 2016 May.
