New Evidence for a Flux-independent Spectral Index of Sgr A* in the Near-infrared

open access: yesThe Astrophysical Journal
In this work, we measure the spectral index of Sagittarius A* (Sgr A*) between the H (1.6 μ m) and $K^{\prime} $ (2.2 μ m) broadband filters in the near-infrared (NIR), sampling over a factor ∼40 in brightness, the largest range probed to date by a ...

Activity and Feeding in Nearby Low Luminosity Galactic Nuclei

open access: yes, 2014
Throughout the last decades a number of correlations between the proper- ties of the supermassive black holes (SMBH) in the center of galaxies and their hosting galaxies have been found. This suggests that these compo- nents influence each other in their evolution.
