gallifrey: JAX-based Gaussian process structure learning for astronomical time series
Christopher Boettner
Gaussian processes (GPs) have become a common tool in astronomy for analysing time series data, particularly in exoplanet science and stellar astrophysics. However, choosing the ap…
Exoplanets Across Galactic Stellar Populations with PLATO: Estimating Exoplanet Yields Around FGK Stars for the Thin Disk, Thick Disk and Stellar Halo
Christopher Boettner, Akshara Viswanathan, Pratika Dayal
This study aims to assess the potential of the upcoming PLATO mission to investigate exoplanet populations around stars in diverse Galactic environments, specifically focusing on t…
Populating The Milky Way: Characterising Planet Demographics by Combining Galaxy Formation Simulations and Planet Population Synthesis Models
C. Boettner, P. Dayal, M. Trebitsch +4
Stellar populations and their distribution differ widely across the Galaxy, which is likely to affect planet demographics. Our local neighbourhood is dominated by young, metal-rich…
A Bayesian approach to the halo galaxy - supermassive black hole connection through cosmic time
Christopher Boettner, Maxime Trebitsch, Pratika Dayal
We study the co-evolution of dark matter halos, galaxies and supermassive black holes using an empirical galaxy evolution model from -- . We demonstrate that by connectin…
Chemical and physical small-scale structure in a pre-stellar core
Andreas Heithausen, Christoph Boettner, Fabian Walter
We present a comparative study of several molecular lines and of the dust contiunuum at 1.2mm in a pre-stellar core that is embedded in the Galactic cirrus cloud MCLD123.5+24.9. Pr…
Cold dust and its relation to molecular gas in the dwarf irregular galaxy NGC 4449
C. Boettner, U. Klein, A. Heithausen
We present observations of the dwarf irregular galaxy NGC 4449 at 850 m and 450 m obtained with SCUBA at the JCMT. The distribution of the cold dust agrees well with that of…
