Spectroastrometry of rotating gas disks for the detection of supermassive black holes in galactic nuclei. III. CRIRES observations of the Circinus galaxy
A. Gnerucci, A. Marconi, A. Capetti +2
We present new CRIRES spectroscopic observations of BrGamma in the nuclear region of the Circinus galaxy, obtained with the aim of measuring the black hole (BH) mass with the spect…
Spectroastrometry of rotating gas disks for the detection of supermassive black holes in galactic nuclei. II. Application to the galaxy Centaurus A (NGC 5128)
A. Gnerucci, A. Marconi, A. Capetti +3
We measure the black hole mass in the nearby active galaxy Centaurus A (NGC 5128) using a new method based on spectroastrometry of a rotating gas disk. The spectroastrometric appro…
A dynamical mass estimator for high z galaxies based on spectroastrometry
A. Gnerucci, A. Marconi, G. Cresci +6
Galaxy dynamical masses are important physical quantities to constrain galaxy evolutionary models, especially at high redshifts. However, at z~2 the limited signal to noise ratio a…
Gas accretion as the origin of chemical abundance gradients in distant galaxies
G. Cresci, F. Mannucci, R. Maiolino +3
It has recently been suggested that galaxies in the early Universe can grow through the accretion of cold gas, and that this may have been the main driver of star formation and ste…
A fundamental relation between mass, SFR and metallicity in local and high redshift galaxies
F. Mannucci, G. Cresci, R. Maiolino +2
We show that the mass-metallicity relation observed in the local universe is due to a more general relation between stellar mass M*, gas-phase metallicity and SFR. Local galaxies d…
Dynamical properties of AMAZE and LSD galaxies from gas kinematics and the Tully-Fisher relation at z~3
A. Gnerucci, A. Marconi, G. Cresci +10
We present a SINFONI integral field kinematical study of 33 galaxies at z~3 from the AMAZE and LSD projects which are aimed at studying metallicity and dynamics of high-redshift ga…
