On dark matter structure in Milky Way-mass galaxies
, 2022 A set of four paired cosmological simulations of Milky Way-mass galaxies are used to examine the dark matter structure. Particular attention is paid to the ability of simulated velocity distributions to inform the experimental search for dark matter and ...

THE SPACE MOTION OF LEO I: THE MASS OF THE MILKY WAY'S DARK MATTER HALO [PDF]
The Astrophysical Journal, 2013 We combine our Hubble Space Telescope measurement of the proper motion of the Leo I dwarf spheroidal galaxy (presented in a companion paper) with the highest resolution numerical simulations of Galaxy-size dark matter halos in existence to constrain the mass of the Milky Way's dark matter halo (M_MW).

Simulated Milky Way analogues: implications for dark matter direct searches [PDF]
We study the implications of galaxy formation on dark matter direct detection using high resolution hydrodynamic simulations of Milky Way-like galaxies simulated within the eagle and apostle projects.

The evolution of dark matter substructure [PDF]
, 2001 This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

The density profile of Milky Way dark matter halo constrained from the OGLE microlensing sky map [PDF]
We report the detection of a 282 $^{+34}_{-31}$ pc-sized core in the center of Milky Way dark matter halo at $68\%$ confidence level by using the micro-lensing event rate sky map data from the Optical Gravitational Lensing Experiment (OGLE) survey.

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.

Small scale structures in coupled scalar field dark matter
Physics Letters B, 2014 We investigate structure formation for ultra-light scalar field dark matter coupled to quintessence, in particular the cosmon–bolon system. The linear power spectrum is computed by a numerical solution of the coupled field equations.

Grand Rotation Curve and Dark-Matter Halo in the Milky Way Galaxy [PDF]
Publications of the Astronomical Society of Japan, 2012 A grand rotation curve of the Milky Way Galaxy was constructed, which covers a wide range of radius from the Galactic Center to $ \sim$ 1 Mpc, and was deconvolved into bulge, disk, and halo components by least-squares fittings. We determined the masses and scale radii of the bulge and disk to be $ {M_{\rm b}}$$ =$ (1.652 $ \pm$ 0.083) $ \times$ 10 ...

Signature of a Dark Ultracompact Dwarf Galaxy Transiting the Milky Way Disk
The Astrophysical Journal LettersWe report the discovery of a vertical velocity anomaly in the stellar component of the Galactic disk, consistent with the impact of a dark, ultracompact dwarf galaxy (UCD)-sized object plunging into the Milky Way.
