Molecular Clouds: Internal Properties, Turbulence, Star Formation and Feedback

Jonathan C. Tan, Suzanne N. Shaske, Sven Van Loo

All stars are born in molecular clouds, and most in giant molecular clouds (GMCs), which thus set the star formation activity of galaxies. We first review their observed properties…

Realizing Fractional Chern Insulators with Dipolar Spins

Norman Y. Yao, Alexey V. Gorshkov, Chris R. Laumann +3

Strongly correlated quantum systems can exhibit exotic behavior controlled by topology. We predict that the ν=1/2 fractional Chern insulator arises naturally in a two-dimensional a…

Bright radio emission from an ultraluminous stellar-mass microquasar in M31

Matthew J. Middleton, James C. A. Miller-Jones, Sera Markoff +34

A subset of ultraluminous X-ray sources (those with luminosities < 10^40 erg/s) are thought to be powered by the accretion of gas onto black holes with masses of ~5-20 M_solar, pro…
