K. ; Gil de Paz, Armando ; Knapen, Johan H. ; Gorgas García, Francisco Javier | IOP publishing ltd | 2020-07Tight correlations between supermassive black hole (SMBH) mass (M_(BH)) and the properties of the host galaxy have useful implications for our understanding of the growth of SMBHs and evolution of galaxies. Here, we present newly observed correl[...]![]()

Madore, Barry F. ; Gil de Paz, Armando ; Pevunova, Olga ; Thompson, Ian | IOP publishing ltd | 2007-07The object NGC 6908 was once thought to simply be a surface brightness enhancement in the eastern spiral arm of the nearby spiral galaxy NGC 6907. Based on an examination of near-infrared imaging, the object is shown to in fact be a lenticular S[...]![]()
