- The Distant Universe
Ongoing star formation and/or the accretion of gas on-to the central supermassive blackholes can drives large-scale outflows of gas in galaxies. These out-flows appear as collimated structures of diffuse hot gas on both sides of the galactic disk usually within few Kpc from the main disk. Using data from the new Australia-led MAGPI survey on the 8-meter Very Large Telescope in Chile, we detect a unique system with a distinct blob of ionised gas almost 25 Kpc away from the nearest galaxy. The nearest galaxy is a massive galaxy with actively accreting super massive black-hole. This project will use the kinematic alignment be-tween ionised gas blob and the central AGN galaxy to test the origin of the ionised gas blob. If confirmed, this galaxy will be the first detection of ionised gas out-flows to such large distances. The student will use the reduced data products created by the MAGPI team from one of the best integral field spectrographs in the world, MUSE, and existing python routines for the emission line fitting. This project will have huge scientific impact because of the novel nature of the target.
Basic knowledge of astronomy and large-scale structures in the Universe.
Experience with Linux and Python would be desirable, but any programming experience would be fine.
Visualization and emission-line analysis technique for spectroscopic datasets. Multi-component gaussian fitting. Plotting with matplotlib and python.
