Molecular gas on large circumgalactic scales at z=3.47
Michele Ginolfi, Roberto Maiolino, Tohru Nagao +9
We report ALMA observations of the most massive (star forming) galaxy in the redshift range 3<z<4 within the whole GOODS-S field. We detect a large elongated structure of molecular…
SDSS IV MaNGA - The spatially resolved transition from star formation to quiescence
Francesco Belfiore, Roberto Maiolino, Claudia Maraston +19
Using spatially resolved spectroscopy from SDSS-IV MaNGA we have demonstrated that low ionisation emission line regions (LIERs) in local galaxies result from photoionisation by hot…
Suppressing star formation in quiescent galaxies with supermassive black hole winds
Edmond Cheung, Kevin Bundy, Michele Cappellari +22
Quiescent galaxies with little or no ongoing star formation dominate the galaxy population above , where their numbers have increased by a fac…
SDSS IV MaNGA - Spatially resolved diagnostic diagrams: A proof that many galaxies are LIERs
Francesco Belfiore, Roberto Maiolino, Claudia Maraston +17
We study the spatially resolved excitation properties of the ionised gas in a sample of 646 galaxies using integral field spectroscopy data from SDSS-IV MaNGA. Making use of Baldwi…
Nitrogen and oxygen abundances in the Local Universe
Fiorenzo Vincenzo, Francesco Belfiore, Roberto Maiolino +2
We present chemical evolution models aimed at reproducing the observed (N/O) vs. (O/H) abundance pattern of star forming galaxies in the Local Universe. We derive gas-phase abundan…
