Secular Evolution in the Milky Way [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractI will review the secular evolution of the Milky Way disk and bulge with particular attention to the bulge and disk. Evidence for the importance of stellar migration in the Solar neighbourhood will be presented. The upcoming Gaia satellite will lead to a wealth of new data with which to explore these effects.

Figure Rotation of IllustrisTNG Halos
The Astrophysical Journal, 2023 We use the TNG50 and TNG50 dark matter (DM)-only simulations from the IllustrisTNG simulation suite to conduct an updated survey of halo figure rotation in the presence of baryons.

A Component of the Smith High-velocity Cloud Now Crossing the Galactic Plane
The Astrophysical Journal, 2023 We have identified a new structure in the Milky Way: a leading component of the Smith high-velocity cloud that is now crossing the Galactic plane near longitude 25°. Using new 21 cm H i data from the Green Bank Telescope (GBT), we measured the properties

The formation and early evolution of the Milky Way [PDF]
Symposium - International Astronomical Union, 1985 In broad outline, the traditional picture for the formation of the Milky Way can be summarized as follows. The proto-galaxy consisted of a slowly rotating cloud of metal-free gas that cooled by bremsstrahlung and recombination radiation. As the internal pressure of the gas decreased, it collapsed in stages with smaller dimensions, faster rotation ...

The evolution of isotope ratios in the Milky Way Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 Isotope ratios have opened a new window into the study of the details of stellar evolution, supernovae, and galactic chemical evolution. We present the evolution of the isotope ratios of elemental abundances (from C to Zn) in the solar neighbourhood, bulge, halo, and thick disk, using chemical evolution models with updated yields of Asymptotic Giant ...

TRAF2 binds to TIFA via a novel motif and contributes to its autophagic degradation
FEBS Letters, EarlyView.TRAF family members couple receptor signalling complexes to downstream outputs, but how they interact with these complexes is not always clear. Here, we show that during ADP‐heptose signalling, TRAF2 binding to TIFA requires two short sequence motifs in the C‐terminal tail of TIFA, which are distinct from the TRAF6 binding motif.

Impact of AGB Stars on the Chemical Evolution of Neutron-Capture Elements
Universe, 2022 In this review, we discuss the impact of s-process nucleosynthesis in asymptotic giant branch stars on the enrichment of heavy elements. We review the main steps made on this subject in the last 40 years and discuss the importance of modelling the ...
