Sagittarius A* is the supermassive black hole at the center of the Milky Way. As supermassive black holes go, it is fairly ...

Accurate wavelengths of the ∼500 lines recorded are given in a table. This material is intended for wavelength calibration of near‐infrared spectra and is especially critical for high‐resolution work.

Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which ...
