    A search for diffuse bands in the circumstellar envelopes of post-AGB stars
    In this work we present the results of a systematic search for diffuse bands (DBs, hereafter) in the circumstellar envelopes of a carefully selected sample of...

    A search for interstellar anthracene towards the Perseus anomalous microwave emission region
    We report the discovery of a new broad interstellar (or circumstellar) band at 7088.8 +/- 2.0 Å coincident to within the measurement uncertainties with the...

    A search for naphthalene in diffuse interstellar clouds
    We have obtained high-resolution optical spectroscopy of 10 reddened O-type stars with Ultraviolet and Visual Echelle Spectrograph at Very Large Telescope to...

    A Simple Synthesis of C60H18 from C60 Fullerene and Hydrogen Iodide
    C60 fullerene can be easily hydrogenated in aromatic solvent under mild conditions with aqueous hydrogen iodide (HI). The resulting black product has the...

    A SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system
    We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster...
  • Publication
    A spatial study of the mid-IR emission features in four Herbig Ae/Be stars
    Context: Infrared (IR) spectroscopy and imaging provide a prime tool to study the characteristics of polycyclic aromatic hydrocarbon (PAH) molecules and the...

    A spectral classification system for hydrogen-deficient carbon stars
    Stellar spectral classification has been highly useful in the study of stars. While there is a currently accepted spectral classification system for carbon...
  • Publication
    A state-of-the-art analysis of the dwarf irregular galaxy NGC 6822
    We present a detailed photometric study of the dwarf irregular galaxy NGC 6822 aimed at investigating the properties of its stellar populations and, in...
  • Publication
    A stellar overdensity associated with the Small Magellanic Cloud
    We report the discovery of a stellar overdensity 8° north of the centre of the Small Magellanic Cloud (SMC; Small Magellanic Cloud Northern Over-Density; SMCNOD...
