Self-interacting Dark Matter Interpretation of Crater II

open access: yesThe Astrophysical Journal Letters
The satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold dark matter.

Interacting and Merging Galaxies

open access: yes, 1996
I will present a review of some of the many recent developments within the exciting and rapidly evolving field of Interacting and Merging Galaxies. I will touch both on observations and on theory, focussing on those aspects where galaxy evolution modelling may possibly contribute to our understanding.

Properties of bars in the local universe

open access: yes, 2008
We studied the fraction and properties of bars in a sample of about 3000 galaxies extracted from SDSS-DR5. This represents a volume limited sample with galaxies located between redshift 0.01-20, and inclination i < 60.

The Effect of Deep Brain Stimulation on Sleep and Cognition in Patients With Parkinson's Disease

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep–wake disturbances and cognitive decline are among the most common nonmotor symptoms of Parkinson's disease (PD). Deep brain stimulation (DBS) can successfully alleviate motor symptoms. However, the impact on sleep–wake disturbances and cognitive decline, and their interaction, is yet unclear.

Dissipation of AGN Jets in a Clumpy Interstellar Medium

open access: yesThe Astrophysical Journal
Accreting supermassive black holes frequently power jets that interact with the interstellar medium (ISM)/circumgalactic medium, regulating star formation in the galaxy.
