Using data from the Large European Array for Pulsars, and the Effelsberg telescope, we study the scintillation parameters of the millisecond pulsar PSR J0613-0200 over a 7 yr timespan. The 'secondary spectrum' - the 2D power spectrum of scintillation... Read More about Measuring interstellar delays of PSR J0613-0200 over 7 yr, using the Large European Array for Pulsars.

The livelihoods of millions of people living in the world's deltas are deeply interconnected with the sediment dynamics of these deltas. In particular a sustainable supply of fluvial sediments from upstream is critical for ensuring the fertility of d...

We present models of CO(1-0) emission from Milky-Way-mass galaxies at redshift zero in the FIRE-2 cosmological zoom-in simulations. We calculate the molecular abundances by post-processing the simulations with an equilibrium chemistry solver while ac...

Monthly notices of the Royal Astronomical Society, 498(3), 3664-3683. https://doi.org/10.1093/mnras/staa2578

Pressure balance plays a central role in models of the interstellar medium (ISM), but whether and how pressure balance is realized in a realistic multiphase ISM is not yet well understood. We address this question by using a set of FIRE-2 cosmologica... Read More about Pressure balance in the multiphase ISM of cosmologically simulated disc galaxies.
