On the diffuse interstellar bands and the local interstellar medium
Published 2017“…This thesis presents results from four different studies on the diffuse interstellar bands and the local interstellar medium. Firstly, a detailed investigation into the profile of the λ6614 diffuse interstellar band (DIB) is presented, which was aimed at ascertaining the origin of the observed fine structure and overall band shape, and why both of these properties change between a number of different lines-of-sight. …”

Polycyclic aromatic hydrocarbons in samples of Ryugu formed in the interstellar medium
Published 2023“…Polycyclic aromatic hydrocarbons (PAHs) contain ≲20% of the carbon in the interstellar medium. They are potentially produced in circumstellar environments (at temperatures ≳1000 kelvin), by reactions within cold (~10 kelvin) interstellar clouds, or by processing of carbon-rich dust grains. …”

Characterising the Local Interstellar Medium using Low-Frequency Pulsar Polarimetry
Published 2019“…Propagation effects on pulsar signals caused by the interstellar medium (ISM) are highly pronounced at low radio frequencies, which makes low-frequency pulsar observations especially promising for the determination of ISM properties. …”

Observations of Low-frequency Radio Emission from Millisecond Pulsars and Multipath Propagation in the Interstellar Medium
Published 2018“…As these effects are much stronger at longer wavelengths, low-frequency observations are most appealing for characterizing the interstellar medium (ISM) along the sight lines toward PTA pulsars. …”

Wide-field VLBI observations of M31: A unique probe of the ionized interstellar medium of a nearby galaxy
Published 2013“…The detected sources were then analyzed for evidence of scatter-broadening due to the ionized interstellar medium (ISM) of M31. The detection of a compact background source only 0.25 kpc projected distance from M31* places a constraint on the extent of any extreme scattering region associated with the center of M31. …”
