s-process production in rotating massive stars at solar and low metallicities (2015)
Journal Article

Rotation was shown to have a strong impact on the structure and light element nucleosynthesis in massive stars. In particular, models including rotation can reproduce the primary nitrogen observed in halo extremely metal poor (EMP) stars. Additional...

Using a sample of ~410,000 galaxies to a depth of IAB=24 over 8.26 deg2 in the Boötes field (~10 times larger than the z~1 luminosity function (LF) studies in the prior literature), we have accurately measured the evolving B-band LF of red galaxies a...

Modern yields per stellar generation: the effect of the IMF (2015)
Journal Article
Vincenzo, F., Matteucci, F., Belfiore, F., & Maiolino, R. (2016). Modern yields per stellar generation: the effect of the IMF. Monthly notices of the Royal Astronomical Society, 455(4), 4183–4190. https://doi.org/10.1093/mnras/stv2598

Gaseous and stellar metallicities in galaxies are nowadays routinely used to constrain the evolutionary processes in galaxies. This requires the knowledge of the average yield per stellar generation, $y_{\text{Z}}$, i.e. the quantity of metals that a...

Monthly notices of the Royal Astronomical Society, 455(4), 3911-3942. https://doi.org/10.1093/mnras/stv2505

We present the Galaxy And Mass Assembly (GAMA) Panchromatic Data Release (PDR) constituting over 230 deg2 of imaging with photometry in 21 bands extending from the far-UV to the far-IR. These data complement our spectroscopic campaign of over 300k ga... Read More about Galaxy and mass assembly (GAMA): Panchromatic data release (far-UV-far-IR) and the low-z energy budget.

H ingestion into He-burning convection zones in super-AGB stellar models as a potential site for intermediate neutron-density nucleosynthesis (2015)
Journal Article

H ingestion into He-burning convection zones in super-AGB stellar models as a potential site for intermediate neutron-density nucleosynthesis. Monthly notices of the Royal Astronomical Society, 455(4), 3848-3863. https://doi.org/10.1093/mnras/stv2488

We investigate the evolution of super-AGB (SAGB) thermal pulse (TP) stars for a range of metallicities (Z) and explore the effect of convective boundary mixing (CBM). With decreasing metallicity and evolution along the TP phase, the He-shell flash an...

We investigate the observational signatures and physical origin of ram-pressure stripping (RPS) in 63 massive galaxy clusters at z = 0.3–0.7, based on images obtained with the Hubble Space Telescope. Using a training set of a dozen ‘jellyfish’ galaxi... Read More about Jellyfish: The origin and distribution of extreme ram-pressure stripping events in massive galaxy clusters.

On the generation of hydrodynamic shocks by mixed beams and occurrence of sunquakes in flares (2015)

Observations of solar flares with sunquakes by space- and ground-based instruments reveal essentially different dynamics of seismic events in different flares. Some sunquakes are found to be closely associated with the locations of hard X-ray (HXR) a...

Several mechanisms have been proposed to explain the transient seismic emission, i.e. “sunquakes,” from some solar flares. Some theories associate high-energy electrons and/or white-light emission with sunquakes. High-energy charged particles and the...
