Fast outflows and star formation quenching in quasar host galaxies
S. Carniani, A. Marconi, R. Maiolino +17
Negative feedback from active galactic nuclei (AGN) is considered a key mechanism in shaping galaxy evolution. Fast, extended outflows are frequently detected in the AGN host galax…
The MAGNUM survey: Positive feedback in the nuclear region of NGC 5643 suggested by MUSE
G. Cresci, A. Marconi, S. Zibetti +18
We study the ionization and kinematics of the ionized gas in the nuclear region of the barred Seyfert 2 galaxy NGC~5643 using MUSE integral field observations in the framework of t…
Is there any evidence that ionised outflows quench star formation in type 1 quasars at z<1?
B. Balmaverde, A. Marconi, M. Brusa +6
The aim of this paper is to test the basic model of negative AGN feedback. According to this model, once the central black hole accretes at the Eddington limit and reaches a certai…
Strongly star-forming rotating disks in a complex merging system at z = 4,7 as revealed by ALMA
S. Carniani, A. Marconi, A. Biggs +10
We performed a kinematical analysis of the [CII] line emission of the BR 1202-0725 system at z~4,7 using ALMA observations. The most prominent sources of this system are a quasar a…
Resolved [CII] emission in a lensed quasar at z=4.4
S. Gallerani, R. Neri, R. Maiolino +9
We present one of the first resolved maps of the [CII] 158 micron line, a powerful tracer of the star forming inter-stellar medium, at high redshift. We use the new IRAM PdBI recei…
The extinction law at high redshift and its implications
S. Gallerani, R. Maiolino, Y. Juarez +9
We analyze the optical-near infrared spectra of 33 quasars with redshifts 3.9<z<6.4 to investigate the properties of dust extinction at these cosmic epochs. The SMC extinction curv…
Strong [CII] emission at high redshift
R. Maiolino, P. Caselli, T. Nagao +3
We report the detection of the [CII]157.74um fine-structure line in the lensed galaxy BRI 0952-0115 at z=4.43, using the APEX telescope. This is the first detection of the [CII] li…
The metallicity of the most distant quasars
Y. Juarez, R. Maiolino, R. Mujica +5
We investigate the metallicity of the broad line region (BLR) of a sample of 30 quasars in the redshift range 4<z<6.4, by using near-IR and optical spectra. We focus on the ratio o…
The evolution of the mass-metallicity relation at z~3
R. Maiolino, T. Nagao, A. Grazian +14
We present preliminary results of an ESO-VLT large programme (AMAZE) aimed at determining the evolution of the mass-metallicity relation at z~3 by means of deep near-IR spectroscop…
First detection of [CII]158um at high redshift: vigorous star formation in the early universe
R. Maiolino, P. Cox, P. Caselli +10
We report the detection of the 2P_3/2 -> 2P_1/2 fine-structure line of C+ at 157.74 micron in SDSSJ114816.64+525150.3 (hereafter J1148+5251), the most distant known quasar, at z=6.…
