Water Production Rates And Activity Of Interstellar Comet 2I/Borisov
We observed the interstellar comet 2I/Borisov using the Neil Gehrels-Swift Observatory’s Ultraviolet/Optical Telescope. We obtained images of the OH gas and dust surrounding the nucleus at four epochs spaced before […]

FLAMINGOS-2 Infrared Photometry of 2I/Borisov
2I/Borisov is the second interstellar object (ISO) after ‘Oumuamua (Meech et al. 2017), but differs from ‘Oumuamua drastically with its extensive cometary activity. A key ingredient to understand the nature […]
