ALMA spectral survey of Supernova 1987A-molecular inventory, chemistry, dynamics and explosive nucleosynthesis (2017)
Journal Article

We report the first molecular line survey of Supernova 1987A in the millimetre wavelength range. In the Atacama Large Millimeter/submillimeter Array (ALMA) 210–300 and 340–360 GHz spectra, we detected cold (20–170 K) CO, 28SiO, HCO+ and SO, with weak...

DUSTiNGS III: Distribution of Intermediate-Age and Old Stellar Populations in Disks and Outer Extremities of Dwarf Galaxies (2017)
Journal Article

We have traced the spatial distributions of intermediate-age and old stars in nine dwarf galaxies in the distant parts of the Local Group, using multi-epoch 3.6 and 4.5 µm data from the DUST in Nearby Galaxies with Spitzer (DUSTiNGS) survey. Using co... Read More about DUSTiNGS III: Distribution of Intermediate-Age and Old Stellar Populations in Disks and Outer Extremities of Dwarf Galaxies.

The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud (2016)
Journal Article

Context. Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (MLRs) is important in quantifying the contribution of evolved stars to...

The mass-loss rates of red supergiants at low metallicity: detection of rotational CO emission from two red supergiants in the Large Magellanic Cloud (2016)
Journal Article

Using the PACS and SPIRE spectrometers on-board the Herschel Space Observatory, we obtained spectra of two red supergiants (RSGs) in the Large Magellanic Cloud (LMC). Multiple rotational CO emission lines (J = 6–5 to 15-14) and 15 H2O lines were dete...

The infrared spectral properties of magellanic carbon stars (2016)
Journal Article

The Infrared Spectrograph on the Spitzer Space Telescope observed 184 carbon stars in the Magellanic Clouds. This sample reveals that the dust-production rate (DPR) from carbon stars generally increases with the pulsation period of the star. The comp...

CK Vul: a smorgasbord of hydrocarbons rules out a 1670 nova (and much else besides) (2016)
Journal Article

We present observations of CK Vul obtained with the Spitzer Space Telescope. The infrared spectrum reveals a warm dust continuum with nebular, molecular hydrogen and HCN lines superimposed, together with the ‘Unidentified Infrared’ features. The nebu...

New quasars behind the Magellanic Clouds. Spectroscopic confirmation of near-infrared selected candidates (2016)
Journal Article

Context. Quasi-stellar objects (quasars) located behind nearby galaxies provide an excellent absolute reference system for astrometric studies, but they are difficult to identify because of fore- and background contamination. Deep wide-field, high an... Read More about New quasars behind the Magellanic Clouds. Spectroscopic confirmation of near-infrared selected candidates.

Integral field spectroscopy of massive young stellar objects in the N113 H II region in the Large Magellanic Cloud (2015)
Journal Article

The Spitzer Surveying the Agents of Galaxy Evolution (SAGE) survey has allowed the identification and analysis of significant samples of Young Stellar Object (YSO) candidates in the Large Magellanic Cloud (LMC). However, the angular resolution of Spi... Read More about Integral field spectroscopy of massive young stellar objects in the N113 H II region in the Large Magellanic Cloud.

The VMC survey - XIV. First results on the look-back time star formation rate tomography of the Small Magellanic Cloud (2015)
Journal Article

We analyse deep images from the VISTA survey of the Magellanic Clouds in the YJKs filters, covering 14 deg2 (10 tiles), split into 120 subregions, and comprising the main body and Wing of the Small Magellanic Cloud (SMC). We apply a colour–magnitude... Read More about The VMC survey - XIV. First results on the look-back time star formation rate tomography of the Small Magellanic Cloud.

The UK Infrared Telescope M33 monitoring project - IV. Variable red giant stars across the galactic disc (2015)
Journal Article

We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope, of the Local Group spiral galaxy M33 (Triangulum). The main aim was to identify stars in the very final stage of their evolution, and for which the luminosity is more... Read More about The UK Infrared Telescope M33 monitoring project - IV.
