A review on success and problem of MOND on globular cluster scale
HongSheng Zhao
Many past attempts to kill MOND have only strengthened the theory. Better data on galaxy velocity curves clearly favor MOND (without fine-tuning) over cold dark matter. The usual c…
Earth-mass dark halos are torn into dark mini-streams by stars
HongSheng Zhao, James E. Taylor, Joseph Silk +1
The promising neutralino dark matter particles generically condense into numerous earth-mass dark halos with smaller substructures suppressed by free streaming\cite{berezinsky}. Th…
A New Mass Degeneracy in Gravitational Lenses: Is there a crisis between a large and the time delay by a large lens halo?
HongSheng Zhao, Bo Qin
Isothermal models and other simple smooth models of dark matter halos of gravitational lenses often predict a dimensionless time delay much too small to be comfortable with…
Evolution of the Galactic Potential and Halo Streamers with Future Astrometric Satellites
HongSheng Zhao, Kathryn Johnston, Lars Hernquist +1
ESA's Global Astrometric Interferometer for Astrophysics (GAIA) holds the promise of mapping out the detailed phase space structure of the Galactic halo by providing unprecedented…
Detecting Halo Streams with GAIA
Amina Helmi, HongSheng Zhao, P. Tim de Zeeuw
We investigate what the proposed ESA astrometric satellite GAIA will reveal by observing the halo of the Milky Way. Specifically, we look for halo streams which are the signatures…
A Self-Consistent Dynamical Model for the {\sl COBE} Observed Galactic Bar and Its Application to Microlensing
HongSheng Zhao
A self-consistent stellar dynamical model for the Galactic bar is constructed from about 500 numerically computed orbits with an extension of the Schwarzschild technique. The model…
