Dissecting ultra-diffuse galaxies in the field. Observational biases and spectroscopic determination of physical properties in low surface brightness systems
Ultra-diffuse galaxies (UDGs) in the field, gravitationally isolated from galaxy clusters, are faint systems that remain poorly represented in the literature due to lack of spectroscopic confirmation and the difficulty of obtaining high signal-to-noise emission-line measurements. We present a spectroscopic study of 17...
