Spitzer mid-IR spectroscopy of powerful 2Jy and 3CRR radio galaxies. I. Evidence against a strong starburst-AGN connection in radio-loud AGN
D. Dicken, C. Tadhunter, D. Axon +9
We present deep Spitzer/IRS spectra for complete samples of 46 2Jy radio galaxies (0.05<z<0.7) and 19 3CRR FRII radio galaxies (z<0.1), and use the detection of polycyclic aromatic…
Dense gas without star formation: The kpc-sized molecular disk in 3C326 N
Nicole Nesvadba, Francois Boulanger, Matt Lehnert +2
We report the discovery of a 3 kpc disk of few 10^9 Ms of dense, warm H_2 in the nearby radio galaxy 3C326 N, which shows no signs of on-going or recent star formation and falls a…
From large scale gas compression to cluster formation in the Antennae overlap region
Cinthya N. Herrera, François Boulanger, Nicole P. H. Nesvadba
We present a detailed observational analysis of how merger-driven turbulence may regulate the star-formation efficiency during galaxy interactions and set the initial conditions fo…
The Average Optical Spectra of Intense Starbursts at z~2: Outflows and the Pressurization of the ISM
L. Le Tiran, M. D. Lehnert, W. van Driel +2
An important property of star-forming galaxies at z~1-2 is the high local star-formation intensities they maintain over tens of kiloparsecs at levels that are only observed in the…
Disk, merger, or outflow ? Molecular gas kinematics in two powerful obscured QSOs at z>3.4
M. Polletta, N. P. H. Nesvadba, R. Neri +3
We report on the detection of bright CO(4-3) line emission in two powerful, obscured quasars discovered in the SWIRE survey, SW022513 and SW022550 at z>3.4. We analyze the line str…
The Na D profiles of nearby low-power radio sources: Jets powering outflows
M. D. Lehnert, C. Tasse, N. P. H. Nesvadba +2
(abridged) We have analyzed the properties of the Na D doublet lines in a large sample of 691 radio galaxies using the Sloan Digital Sky Survey (SDSS). These radio galaxies are res…
