The Chemistry of the Milky Way: From Micro- to Macro-Physics
The Chemistry of the Milky Way: From Micro- to Macro-Physics. The physics of galaxy formation in the early Universe is driving the development of billion-dollar investments such as the Next Generation Space Telescope and the Square Kilometre Array.

Testing the dark matter caustic theory against observations in the Milky Way
, 2015 August 2015School of ScienceWe test a particular theory of dark matter in which dark matter axions form ring ``caustics" in the plane of the Milky Way, against the observations of Milky Way stars. According to this theory, cold, collisionless dark matter

Molecular Clouds Resolved at the Onset of Cosmic Noon
The Astrophysical Journal LettersWe present the discovery of seven molecular clouds in the radio galaxy B2 0902+34 at redshift z = 3.4. These clouds are detected as CO(0–1) absorption features against the bright radio continuum and spectrally resolved using the Karl G. Jansky Very Large

A Turbulent Framework for Star Formation in High-redshift Galaxies
The Astrophysical JournalObservations of distant galaxies suggest that the physics of galaxy formation at high redshifts differs significantly from later times. In contrast to large, steady disk galaxies like the Milky Way, high-redshift galaxies are often characterized by ...

The Astrophysical Journal LettersA substantial fraction of stars can be found in wide binaries with projected separations between ∼10 ^2 and 10 ^5 au. In the standard lore of binary physics, these would evolve as effectively single stars that remotely orbit one another on stationary ...

Dark matter substructure in the Milky Way
The standard Lambda-CDM cosmological model predicts a wealth of small-scale structures, including dark matter subhalos residing within more massive halos such as that of our own Milky Way galaxy. While some of these subhalos may be massive enough to host
