We have followed up two ultra-diffuse galaxies (UDGs), detected adjacent to stellar streams, with Hubble Space Telescope (HST) imaging and H i mapping with the Jansky Very Large Array (VLA) in order to investigate the possibility that they might have a tidal origin. With the HST F814W and F555W images we measure the globular cluster (GC) counts for NGC 2708-Dw1 and NGC 5631-Dw1 as 2 −1 and 5 +1 −2, respectively. NGC 2708-Dw1 is undetected in H i down to a 3σ limit of log(MHI/M ) = 7.3, and… Expand
