The total mass of the Large Magellanic Cloud from its perturbation on the Orphan stream [PDF]
Monthly notices of the Royal Astronomical Society, 2019 In a companion paper by Koposov et al., RR Lyrae from Gaia Data Release 2 are used to demonstrate that stars in the Orphan stream have velocity vectors significantly misaligned with the stream track, suggesting that it has received a large gravitational ...

The Detection of Hot Cores and Complex Organic Molecules in the Large Magellanic Cloud [PDF]
, 2018 We report the first extragalactic detection of the complex organic molecules (COMs) dimethyl ether (CH3OCH3) and methyl formate (CH3OCHO) with the Atacama Large Millimeter/submillimeter Array (ALMA).

Measuring the Mass of the Large Magellanic Cloud with Stellar Streams Observed by S 5 [PDF]
Astrophysical Journal, 2021 Stellar streams are excellent probes of the underlying gravitational potential in which they evolve. In this work, we fit dynamical models to five streams in the Southern Galactic hemisphere, combining observations from the Southern Stellar Stream ...

The EMU view of the Large Magellanic Cloud: troubles for sub-TeV WIMPs [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We present a radio search for WIMP dark matter in the Large Magellanic Cloud (LMC). We make use of a recent deep image of the LMC obtained from observations of the Australian Square Kilometre Array Pathfinder (ASKAP), and processed as part of the ...

Kinematic Decomposition of the H i Gaseous Component in the Large Magellanic Cloud
The Astrophysical Journal, 2022 We perform a profile analysis of the combined H i data cube of the Large Magellanic Cloud (LMC) from observations with the Australia Telescope Compact Array and the Parkes radio telescope. For the profile analysis, we use a newly developed algorithm that

Discovery of the Magellanic Stellar Stream Out to 100 kpc
The Astrophysical Journal, 2023 The Magellanic Stream (MS)—an enormous ribbon of gas spanning 140° of the southern sky trailing the Magellanic Clouds—has been exquisitely mapped in the five decades since its discovery.

A distance to the Large Magellanic Cloud that is precise to one per cent [PDF]
Nature, 2019 In the era of precision cosmology, it is essential to determine the Hubble constant empirically with an accuracy of one per cent or better1. At present, the uncertainty on this constant is dominated by the uncertainty in the calibration of the Cepheid ...
