STELLAR VELOCITY DISPERSION AND ANISOTROPY OF THE MILKY WAY INNER HALO [PDF]
The Astrophysical Journal, 2015 We measure the three components of velocity dispersion, $σ_{R},σ_θ,σ_ϕ$, for stars within 6 < R < 30 kpc of the Milky Way using a new radial velocity sample from the MMT telescope. We combine our measurements with previously published data so that we can more finely sample the stellar halo.

Stars made in outflows may populate the stellar halo of the Milky Way [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We study stellar-halo formation using six Milky-Way-mass galaxies in FIRE-2 cosmological zoom simulations. We find that $5{-}40{{\ \rm per\ cent}}$ of the outer (50–300 kpc) stellar halo in each system consists of in-situ stars that were born in ...

Stellar haloes in Milky Way mass galaxies: from the inner to the outer haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We present a comprehensive study of the chemical properties of the stellar haloes of Milky-Way mass galaxies, analysing the transition between the inner to the outer haloes. We find the transition radius between the relative dominance of the inner-halo and outer-halo stellar populations to be ~15-20 kpc for most of our haloes, similar to that inferred ...

Anisotropy of the Milky Way’s Stellar Halo Using K Giants from LAMOST and Gaia [PDF]
Astronomical Journal, 2018 The anisotropy parameter β characterizes the extent to which orbits in stellar systems are predominantly radial or tangential and is likely to constrain, for the stellar halo of the Milky Way, scenarios for its formation and evolution. We have measured β

The effects of dynamical substructure on Milky Way mass estimates from the high-velocity tail of the local stellar halo [PDF]
Monthly Notices of the Royal Astronomical Society Letters, 2019 We investigate the impact of dynamical streams and substructure on estimates of the local escape speed and total mass of Milky-Way-mass galaxies from modelling the high-velocity tail of local halo stars.

Are dSph galaxies Galactic building blocks?
EPJ Web of Conferences, 2012 Dwarf spheroidal galaxies (dSph) are frequently assumed to represent surviving examples of a vast now destroyed population of small systems in which many of the stars now forming the Milky Way were formed. Ongoing accretion and considerable sub-structure

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.
