Potential impact of the Sagittarius dwarf galaxy on the formation of young O-rich stars [PDF]
Nature CommunicationsThe Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notable star formation events over the past 4 Gyr, likely triggered by ...

POLARIZED EMISSION OF SAGITTARIUS A* [PDF]
The Astrophysical Journal, 2009 We explore the parameter space of the two temperature pseudo-Newtonian Keplerian accretion flow model for the millimeter and shorter wavelength emission from Sagittarius A*. A general relativistic ray-tracing code is used to treat the radiative transfer of polarized synchrotron emission from the flow.

A Relativistic Disk in Sagittarius A* [PDF]
Astronomische Nachrichten, 2003 The detection of a mm/Sub-mm ``bump'' in Sgr A*'s radio spectrum suggests that at least a portion of its overall emission is produced within a compact accretion torus. This inference is strengthened by observations of strong linear polarization (at the 10 percent level) within this bump. No linear polarization has been detected yet at other wavelengths.

What Does the Milky Way Look Like?
The Astrophysical Journal, 2023 In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided us with an opportunity to solve this issue.

The Disruption of the Sagittarius Dwarf Galaxy [PDF]
The Astrophysical Journal, 1995 Numerical simulations of dwarf spheroidal galaxies undergoing several close encounters with the Milky Way are described. By comparing our models to observed properties of the recently discovered dwarf galaxy in Sagittarius (Sgr), we discuss implications of our results for the formation and evolution of the Milky Way system.
