Observations of the gamma-ray emitting narrow-line Seyfert 1, SBS 0846+513, and its host galaxy

Timothy S. Hamilton, Marco Berton, Sonia Antón +9

The gamma-ray emitting galaxy SBS 0846+513 has been classified as a Narrow-Line Seyfert 1 from its spectroscopy, and on that basis it was thought likely to have a small central bla…
