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…

The S2N2 metallicity calibrator and the abundance gradient of M 33
K. Viironen, G. Delgado-Inglada, A. Mampaso +2
We introduce the log(Ha/[SII]6717+6731) vs. log(Ha/[NII]6583) (S2N2) diagnostic diagram as metallicity and ionisation parameter indicator for HII regions in external galaxies. The…

New candidate planetary nebulae in M81
L. Magrini, M. Perinotto, R. L. M. Corradi +1
A 34 x 34 arcmin field centred on the spiral galaxy M81 has been searched for emission-line objects using the prime focus wide field camera (WFC) of the 2.54 m Isaac Newton Telesco…
