A 5x10^9 Solar Mass Black Hole in NGC 1277 from Adaptive Optics Spectroscopy
Jonelle L. Walsh, Remco C. E. van den Bosch, Karl Gebhardt +4
The nearby lenticular galaxy NGC 1277 is thought to host one of the largest black holes known, however the black hole mass measurement is based on low spatial resolution spectrosco…
The massive dark halo of the compact, early-type galaxy NGC 1281
Akın Yıldırım, Remco van den Bosch, Glenn van de Ven +7
We investigate the compact, early-type galaxy NGC 1281 with integral field unit observations to map the stellar LOSVD out to 5 effective radii and construct orbit-based dynamical m…
MRK 1216 & NGC 1277 - An orbit-based dynamical analysis of compact, high velocity dispersion galaxies
Akın Yıldırım, Remco van den Bosch, Glenn van de Ven +5
We present a dynamical analysis to infer the structural parameters and properties of the two nearby, compact, high velocity dispersion galaxies MRK1216 & NGC1277. Combining deep HS…
The Black Hole in the Compact, High-dispersion Galaxy NGC 1271
Jonelle L. Walsh, Remco C. E. van den Bosch, Karl Gebhardt +4
Located in the Perseus cluster, NGC 1271 is an early-type galaxy with a small effective radius of 2.2 kpc and a large stellar velocity dispersion of 276 km/s for its K-band luminos…
Massive relic galaxies challenge the co-evolution of SMBHs and their host galaxies
Anna Ferré-Mateu, Mar Mezcua, Ignacio Trujillo +2
We study a sample of eight massive galaxies that are extreme outliers (3-5) in the M-M local scaling relation. Two of these galaxies are confirmed t…
