With the advent of massive large-scale sky surveys, such as, the SDSS for photometry, the LAMOST for spectroscopy, and Gaia for astrometry, we are entering a golden era of Galactic studies and precise multi-dimensional information (e.g., 3D position, 3D velocity, chemical element abundance ratios, and stellar age) is now available for some huge samples of stars in the Milky Way. Leveraging thes...
Estimating the spin of SgrA∗ is one of the current challenges we face in understanding the center of our Galaxy. In the present work, we show that detecting the gravitational waves (GWs) emitted by a brown dwarf inspiraling around SgrA∗ will allow us to measure the mass and the spin of SgrA∗ with unprecedented accuracy. Such systems are known as extremely large mass-ratio inspirals (XMRIs) a...
The advent of integral field data has revolutionised the study of galaxy evolution. A key component of this is dynamical modelling methods which have allowed for crucial insights to be made from kinematic data. Despite this importance, most dynamical models make a number of key assumptions which do not hold for real galaxies. At the same time, machine learning methods are becoming increasingly ...
Kinematic studies of protoplanetary discs are becoming a valuable method for uncovering hidden companions. While there exists a substantial amount of literature on the understanding of planet-disc interactions and their observational implications, little attention has been made towards circumbinary discs. Using 3D hydrodynamical simulations post-processed with Monte Carlo radiative transfer, I ...
The 4-m Multi-Object Spectroscopic Telescope (4MOST) is one of the ESO community survey with a large field-of-view to survey the southern sky in a few years, delivering spectra for ≥25 million objects over ≥15 000 square degrees in R~6000 and R~20000. 4MOST is currently in its manufacturing, assembly, integration and test phase with an expected start of full science operations within a year. ...
