The Atlas3D project -- XXVII. Cold Gas and the Colours and Ages of Early-type Galaxies
L. M. Young, N. Scott, P. Serra +22
We present a study of the cold gas contents of the Atlas3D early-type galaxies, in the context of their optical colours, near-UV colours, and Hβ absorption line strengths. Early-ty…
NGC1266 as a Local Candidate for Rapid Cessation of Star Formation
Katherine Alatalo, Kristina Nyland, Genevieve Graves +27
We present new Spectrographic Areal Unit for Research on Optical Nebulae (SAURON) integral-field spectroscopy and Swift Ultraviolet Optical Telescope (UVOT) observations of molecul…
The ATLAS project - XXV: Two-dimensional kinematic analysis of simulated galaxies and the cosmological origin of fast and slow rotators
T. Naab, L. Oser, E. Emsellem +26
We present a detailed two-dimensional stellar dynamical analysis of a sample of 44 cosmological hydrodynamical simulations of individual central galaxies and their satellites. Kine…
Detection of a High Brightness Temperature Radio Core in the AGN-Driven Molecular Outflow Candidate NGC 1266
Kristina Nyland, Katherine Alatalo, J. M. Wrobel +6
We present new high spatial resolution Karl G. Jansky Very Large Array (VLA) HI absorption and Very Long Baseline Array (VLBA) continuum observations of the Active Galactic Nucleus…
The ATLAS3D Project -- XXIII. Angular momentum and nuclear surface brightness profiles
Davor Krajnovic, A. M. Karick, Roger L. Davies +22
[Abridged and Edited] We investigate nuclear light profiles in 135 ATLAS3D galaxies for which the Hubble Space Telescope (HST) imaging is available and compare them to the large sc…
The M_BH - sigma relation for intermediate-mass black holes in globular clusters
Nora Lützgendorf, Markus Kissler-Patig, Nadine Neumayer +6
For galaxies hosting supermassive black holes (SMBHs), it has been observed that the mass of the central black hole (M_BH) tightly correlates with the effective or central velocity…
Indication for an intermediate-mass black hole in the globular cluster NGC 5286 from kinematics
A. Feldmeier, N. Lützgendorf, N. Neumayer +6
Intermediate-mass black holes (IMBHs, 10^2-10^5 M_sun) fill the gap between stellar-mass black holes and supermassive black holes (SMBHs). Simulations have shown that IMBHs may for…
Probing the mass assembly of massive nearby galaxies with deep imaging
Pierre-Alain Duc
According to a popular scenario supported by numerical models, the mass assembly and growth of massive galaxies, in particular the Early-Type Galaxies (ETGs), is, below a redshift…
The Atlas3D project - XIX. The hot-gas content of early-type galaxies: fast versus slow rotators
Marc Sarzi, Katherine Alatalo, Leo Blitz +20
For early-type galaxies, the ability to sustain a corona of hot, X-ray emitting gas could have played a key role in quenching their star-formation history. Yet, it is still unclear…
