The Milky Way’s Circular Velocity Curve Measured Using Element Abundance Gradients
The Astrophysical JournalSpectroscopic surveys now supply precise stellar label measurements such as element abundances for large samples of stars throughout the Milky Way. These element abundances are known to correlate with orbital actions or other dynamical invariants.

The Formalism of Milky-Way Antimatter-Domains Evolution
Galaxies, 2023 If baryosynthesis is strongly nonhomogeneous, macroscopic regions with antibaryon excess can be created in the same process from which the baryonic matter is originated. This exotic possibility can become real, if the hints to the existence of antihelium

Finding novel vulnerabilities of hypomorphic BRCA1 alleles
Molecular Oncology, EarlyView.Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Andromeda and the Milky Way: Twin sisters, distant relations, or strangers in the night?
, 2012 I summarize some recent key results from the Pan-Andromeda Archaeological Survey (PAndAS), in particular showing how recent discoveries in and around M31 compare to the known structure of the Milky Way and its satellite ...

The Age-dependent Vertical Actions of Young Stars in the Galaxy
The Astrophysical JournalStars in the Galactic disk are born on cold, nearly circular orbits with small vertical excursions. After their birth, their orbits evolve, driven by small- or large-scale perturbations in the Galactic disk’s gravitational potential.

Contrasting copper evolution in ω Centauri and the Milky Way [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2007 Abstract Despite the many studies on stellar nucleosynthesis published so far, the scenario for the production of copper in stars remains elusive. In particular, it is still debated whether copper originates mostly in massive stars or in Type Ia supernovae.

MITF maintains genome stability in nonmelanocyte lineages
Molecular Oncology, EarlyView.MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

The chemo-dynamical evolution of the Milky Way disc
, 2016 The kinematic properties of the stellar subpopulations in the Milky Way disc are linked to their radial and vertical scale lengths. On the other hand, element abundances and abundance ratios are a signature of the evolution history of the stellar ...

Are the Milky Way and Andromeda unusual? A comparison with Milky Way and Andromeda analogues
, 2020 Our Milky Way provides a unique test case for galaxy evolution models because of our privileged position within the Milky Way's disc. This position also complicates comparisons between the Milky Way and external galaxies, due to our inability to observe ...
