Validation of the magnetic energy vs. helicity scaling in solar magnetic structures
(2014-10) - Journal item,
Aims. We assess the validity of the free magnetic energy - relative magnetic helicity diagram for solar magnetic structures. Methods. We used two different methods of calculating the free magnetic energy and the relative ...
John W. Arthur, Brilliant Lives: the Clerk Maxwells and the Scottish Enlightenment
(2017-11) - Journal item,
Is magnetic topology important for heating the solar atmosphere?
(2015-05-28) - Journal item,
Magnetic fields permeate the entire solar atmosphere weaving an extremely complex pattern on both local and global scales. In order to understand the nature of this tangled web of magnetic fields, its magnetic skeleton, ...
Extinction is imminent for Mexico’s endemic porpoise unless fishery bycatch is eliminated
(2017-10-12) - Journal item,
The number of Mexico’s endemic porpoise, the vaquita (Phocoena sinus), is collapsing primarily due to bycatch in illegal gillnets set for totoaba (Totoaba macdonaldi), an endangered fish whose swim bladders are exported ...
Marine mammals and sonar : dose-response studies, the risk-disturbance hypothesis and the role of exposure context
(2018-01) - Journal item,
1. Marine mammals may be negatively affected by anthropogenic noise. Behavioural response studies (BRSs) aim to establish a relationship between the exposure dose of a stressor and associated behavioural responses of ...
Modeling observed decay-less oscillations as resonantly enhanced Kelvin-Helmholtz vortices from transverse MHD waves and their seismological application
(2016-10-12) - Journal item,
In the highly structured solar corona, resonant absorption is an unavoidable mechanism of energy transfer from global transverse MHD waves to local azimuthal Alfvén waves. Due to its localised nature, a direct detection ...
On the connection between propagating solar coronal disturbances and chromospheric footpoints
(2016-09) - Journal item,
The Interface Region Imaging Spectrograph (IRIS) provides an unparalleled opportunity to explore the (thermal) interface between the chromosphere, transition region, and the coronal plasma observed by the Atmospheric Imaging ...
The Sun's global photospheric and coronal magnetic fields : observations and models
(2012-11) - Journal item,
In this review, our present day understanding of the Sun's global photospheric and coronal magnetic fields is discussed from both observational and theoretical viewpoints. Firstly, the large-scale properties of photospheric ...
