A new era in galaxy edge characterisation with ultra-deep imaging
For the first time, the LIGHTS survey is routinely imaging galaxies at a depth and spatial resolution comparable to what LSST will produce in 10 years (i.e. ~31...
A new ionization correction scheme for He(+)/H(+) and the determination of the helium abundance in H II regions
A new ionization correction factor (ICF) scheme for He(+) is developed, based on the definition of the radiation softness parameter eta (Vilchez and Pagel, 1988...
A New Measurement of the 6Li / 7Li Ratio in HD 82943
We investigate the presence of possible blends in the spectral region of the Li resonance line at 6708Å in solar-type metal-rich stars using high resolution and...
A New Method for Unveiling Box/Peanut Bulges in Face-On Galaxies
We measured the stellar kinematics of three face-on galaxies with the aim of searching for box/peanut-shaped (B/P) bulges. These observations test and confirm...
