Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae
Published 2018“…In this work we study the kinematics of the globular cluster (GC) systems of three lenticular galaxies located in low density environments (NGC2768, NGC3115 and NGC7457), and compare them with the kinematics of planetary nebulae (PNe). The PNe and GC data come from the Planetary Nebulae Spectrograph and the SLUGGS Surveys. …”

A search for near infrared counterparts of three pulsar wind nebulae
Published 2011“…Context. While pulsar wind nebulae (PWNe) and their associated isolated pulsars are commonly detected at X-ray energies, they aremuch rarer at near infrared (nIR) and optical wavelengths.Aims. …”

Unusual shock-excited oh maser emission in a young Planetary Nebula
Published 2016“…We report on OH maser emission toward G336.644-0.695 (IRAS 16333-4807), which is a H2O maser-emitting Planetary Nebula (PN). We have detected 1612, 1667, and 1720 MHz OH masers at two epochs using the Australia Telescope Compact Array, hereby confirming it as the seventh known case of an OH-maser-emitting PN. …”

Optical and X-ray luminosities of expanding nebulae around ultraluminous X-ray sources
Published 2017“…We have performed a set of simulations of expanding, spherically symmetric nebulae inflated by winds from accreting black holes in ultraluminous X-ray sources (ULXs).We implemented a realistic cooling function to account for free-free and bound-free cooling. …”

Radio detection of nebulae around four luminous blue variable stars in the Large Magellanic Cloud
Published 2012“…The nebulae associated with four luminous blue variables (LBVs) in the Large Magellanic Cloud (LMC) have been observed at 5.5 and 9GHz using the Australia Telescope Compact Array, and radio emission has been detected for first time in sources R127, R143, S61 and S119. …”

High radio frequency sample of bright planetary nebulae in the Southern hemisphere detected in the AT20G survey
Published 2015“…Using a combination of radio spectra, radio interferometric technique and infrared spectra fromWide-field Infrared Survey Explorer, we provide an effective method of identifying further candidates and we list a total of six new planetary nebulae that require follow-up. Together with the list of planetary nebula candidates and the planetary nebulae from the AT20G survey presented in this paper, we provide radio spectra for a complete radio flux limited sample of planetary nebulae at |b| > 1.5 deg in the Southern hemisphere at 20 GHz.…”
