VizieR Online Data Catalog: GBT HI obs. of ultradiffuse galaxies (Karunakaran+, 2020)
Abstract
We performed 88hr of position-switched HI observations between 2018 February and 2018 August using the Robert C. Byrd Green Bank Telescope (GBT) along the lines of sight (LOSs) to the 70 ultra-diffuse galaxy (UDG) candidates in Table 1 (program AGBT18B-239). Nine objects were observed with an offset between the optical centroid and the LOS in order to minimize contamination from known nearby objects (see Section 4.1).
We used the L-band receiver and the Versatile GBT Astronomical Spectrometer (VEGAS) with a spectral resolution of 3.1kHz and a wide bandpass of 100MHz. (5 data files).- Publication:
