Stability of disk-like galaxies--Part I: Stability via reduction [PDF]
, 2006 We prove the existence and stability of flat steady states of the Vlasov-Poisson system, which in astrophysics are used as models of disk-like galaxies.

Simulations of stellar convection, pulsation and semiconvection [PDF]
, 2010 We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations.

Galaxy clusters as astrophysical laboratories and probes of cosmology [PDF]
, 2014 Galaxy clusters are the most recent of cosmological structures to have formed by the present time in the currently favoured hierarchical scenario of structure formation and are widely regarded as powerful probes of cosmology and galaxy formation physics alike.

Cross-correlation of the astrophysical gravitational-wave background with galaxy clustering
Physical Review D, 2020 We investigate the correlation between the distribution of galaxies and the predicted gravitational-wave background of astrophysical origin. We show that the large angular scale anisotropies of this background are dominated by nearby non-linear structure, which depends on the notoriously hard to model galaxy power spectrum at small scales. In contrast,

Micro-Arcsecond Radio Astrometry
, 2013 Astrometry provides the foundation for astrophysics. Accurate positions are required for the association of sources detected at different times or wavelengths, and distances are essential to estimate the size, luminosity, mass, and ages of most objects ...

Giant radio galaxies as probes of the ambient WHIM in the era of the SKA
, 2015 The missing baryons are usually thought to reside in galaxy filaments as warm-hot intergalactic medium (WHIM). From previous studies, giant radio galaxies are usually associated with galaxy groups, which normally trace the WHIM.

Theory and laboratory astrophysics [PDF]
Science opportunities in the 1990's are discussed. Topics covered include the large scale structure of the universe, galaxies, stars, star formation and the interstellar medium, high energy astrophysics, and the solar system.

Physical modelling of galaxy clusters and Bayesian inference in astrophysics
arXiv: Cosmology and Nongalactic Astrophysics, 2019 I compare the mass values obtained with data taken from the Arcminute Microkelvin Imager (AMI) radio interferometer system and from the Planck satellite. The former of these uses a Bayesian analysis pipeline that parameterises a cluster in terms of its physical quantities, and models the dark matter \& baryonic components of a cluster using Navarro-
