“My main research area is Asteroseismology, which is the study of oscillations inside stars to learn more about their interior physical properties and processes. My current ERC\/UKRI Frontier Research Grant, SYMPHONY<\/strong><\/a>, focuses on asteroseismology of massive stars, which are those that will eventually explode as violent supernovae and leave behind a neutron star or black hole. The project is using existing and developing new techniques for applying asteroseismology and determining the physical properties of massive stars, with a particular focus on Blue Supergiants, such as their interior rotation profiles, masses and ages. These properties are not accurately known for massive stars because our best current theoretical models contain large uncertainties. Massive stars have self-excited gravity and pressure mode oscillations which probe the deep stellar interiors and radiative envelopes, respectively, thus provide excellent insight of the physics at work within stellar interiors.<\/em><\/em>“

“I use X-ray observations and theoretical modelling to probe the environment of accreting black holes and neutron stars. This helps us learn about the very strong gravitational fields close to black hole event horizons, and how these objects formed and grew to their current sizes. I study quasi-periodic oscillations (QPOs) – nearly periodic changes in the observed X-ray brightness of the accreting plasma – and the idea that these result from relativistic precession. I also use the variability of reflected X-rays to constrain the geometry close to the black hole and measure its mass. I am interested in using X-ray polarimetry to learn about black holes and neutron stars, a field that will be revolutionized when IXPE launches in 2021.

“I am a theoretical astrophysicist exploring the interface between binary star physics and asteroseismology. Studying binary star systems has been extremely valuable for our understanding of stellar structure and evolution. However, the various, often ill-constrained interactions between stars in a binary system add a layer of complexity to truly unravelling the lives of binary components and their ultimate products. By making the connection with asteroseismology, the study of stellar interiors using stellar pulsations, I aim to untangle some of these complexities. Originally from Belgium, I completed my BSc in Physics and MSc in Astronomy and Astrophysics at KU Leuven from 2015 to 2020. During my MSc studies in Leuven, I came into contact with binary physics and asteroseismology for the first time, and ended up writing my MSc thesis on the effects of the centrifugal acceleration on gravity-mode pulsations in intermediate-mass stars. Afterwards, in February 2021, I moved to Heidelberg (Germany) and started my PhD at the Heidelberg Institute for Theoretical Studies (HITS). During my PhD, I computed large grids of 1D binary evolution models to predict which binary systems are likely to result in stellar mergers. Afterwards, I began exploring whether and how asteroseismology can help us distinguish between merger products and stars born as single stars by predicting the properties of their pulsations. In June 2025, I started my first postdoc in the group of Dominic Bowman at Newcastle University, where I will continue to work on binary stars and asteroseismology, and expand my scope to new topics and techniques.”<\/em><\/p>\n\n\n\n

“I am a Theoretical Physics PhD student in the Astro-Obs group, studying under Dr. Andrei Igoshev and funded by the Royal Society. The main focus of my research concerns the modelling of magnetic fields in the cores of ‘type II superconducting neutron stars’. Neutron stars are relatively cold, in a quantum sense, and are the densest objects in the universe. This means that some of the particles in the interior, the neutrons and protons, are expected to be in a quantum state of matter where they can flow with no effective resistance, known as superfluidity and superconductivity. The flow of charged particles, such as protons and electrons, generates a magnetic field, which itself creates a force on the charged fluid and influences its flow. The study of the motion of charged fluids and their magnetic fields is called magnetohydrodynamics, and many Astro-Obs members use its framework in their research. I use advanced numerical techniques to simulate the multi-fluid magnetohydrodynamics of the core of neutron stars, taking into consideration the superconducting and superfluid nature, following from the work of Andrei Igoshev and collaborators.

The innermost region of accretion, which we call the corona, is too small for us to spatially resolve (we observe it as a point source) and so in order to study these regions, we consider the X-ray signature of the matter as it falls onto the compact object. This signature displays Type-C QPOs- a broad peak above a broadband noise in the Powerspectrum of the X-ray lightcurve of the corona, the origin of which remains elusive.

“I’m originally from Italy, and spent a couple of years in Belgium at the Institute of Astronomy, KU Leuven studying to obtain my MSc in Astronomy and Astrophysics. Since January 2024, I am based at Newcastle University for my PhD in Astrophysics under the supervision of Dr. Dominic Bowman as part of the SYMPHONY project. I enjoy exploring new places, meeting people from all over the world and learning about their culture. In my free time, you will find me at concerts, museums, and soaking up the arts. My research focus is on pulsating massive stars within binary systems, and I am interested in the relationship between self-excited pulsations and the orbital properties. Using spectroscopy and asteroseismology, the goal of my PhD is to understand how pulsations in massive binary systems can be most effectively exploited to learn more about binary massive star evolution and how this may differ to single stars.”<\/em><\/p>\n\n\n\n

Rose Shepherd<\/strong>
Rose is a PhD student and her supervisors are Chris Harrison and Paul Vickers (Northumbria University). She joined Newcastle in 2023 as part of the NUdata CDT.

“My PhD project is focused on developing sonification methods and tools to explore large, astronomical datasets. Sonification is the process of representing data with sound. I will investigate whether sonification can be beneficial in the identification and classification of quasars from their spectra. I will also be using sonification to explore spectral data cubes which could potentially aid discovery of extended emission line regions. Sonification offers innovative outreach possibilities, and I am excited to get involved with the Audio Universe<\/a> team, making accessible planetarium shows and resources. Outside of my studies I enjoy playing clarinet, and I hope to apply my musical skills to my sonification research.”<\/em><\/p>\n\n\n\n

“My PhD project involves testing gravity on cosmological scales by using agnostic parametrisations for modified gravity.<\/em> This involves exploring parameter estimations from different observational probes and testing data by considering specific alternative theories of gravity. I will also be studying degeneracies between gravitational parameters to find accurate physical interpretations of true descriptors of theories.<\/em>“<\/p>\n\n\n\n

“My research involves developing a hybrid Dark Matter (DM) model that combines the existing Cold Dark Matter (CDM) model with a \u201cFuzzy\u201d Dark Matter (FDM) model and treats DM as a cosmological superfluid. While the existing DM model is extremely successful at a macroscopic level (Large-Scale Structure Formation), discrepancies start to arise at galactic-halo scales, and FDM aims to tackle these. The goal is to perform high end non-linear simulations for such a model, to attain a richer phenomenology that can confront results of galaxy surveys and allow for refined constraints on the physical parameters that govern these models. The aim is to achieve this by focusing on stellar trajectories in FDM halos and how these would translate to observable rotation curves<\/em><\/em>.<\/em>“<\/p>\n\n\n\n
