The Intrinsic Structure of Sagittarius A* at 1.3 cm and 7 mm [PDF]

open access: yesAstrophysical Journal, 2021
Sagittarius A* (Sgr A*), the Galactic Center supermassive black hole (SMBH), is one of the best targets in which to resolve the innermost region of an SMBH with very long baseline interferometry (VLBI).

Tango for three: Sagittarius, LMC, and the Milky Way [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
We assemble a catalogue of candidate Sagittarius stream members with 5D and 6D phase-space information, using astrometric data from Gaia DR2, distances estimated from RR Lyrae stars, and line-of-sight velocities from various spectroscopic surveys.

A high pitch angle structure in the Sagittarius Arm [PDF]

open access: yesAstronomy & Astrophysics, 2021
Context. In spiral galaxies, star formation tends to trace features of the spiral pattern, including arms, spurs, feathers, and branches. However, in our own Milky Way, it has been challenging to connect individual star-forming regions to their larger ...

The Sagittarius stream in Gaia Early Data Release 3 and the origin of the bifurcations [PDF]

open access: yesAstronomy & Astrophysics, 2021
The Sagittarius dwarf spheroidal (Sgr) is a dissolving galaxy being tidally disrupted by the Milky Way (MW). Its stellar stream still poses serious modelling challenges, which hinders our ability to use it effectively as a probe of the MW gravitational ...

POLARIZED EMISSION OF SAGITTARIUS A* [PDF]

open access: yesThe 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.

Ab Initio Horizon-scale Simulations of Magnetically Arrested Accretion in Sagittarius A* Fed by Stellar Winds [PDF]

open access: yesAstrophysical Journal, 2020
We present 3D general relativistic magnetohydrodynamic (GRMHD) simulations of the accretion flow surrounding Sagittarius A* that are initialized using larger-scale MHD simulations of the ∼30 Wolf–Rayet (WR) stellar winds in the Galactic center.
