Daniel Brown has been a lecturer in physics and mathematics at the University of Central Lancashire since September 2009. He is research active within the area of astrophysics and is a member of the Solar Physics Research Group which is part of the Jeremiah Horrocks Institute.

Daniel has previously worked at Aberystwyth University and the University of St Andrews. As part of his research he analyses observations from NASA's Solar Dynamics Observatory.

Full Profile

Daniel Brown graduated from his PhD in Solar Physics from the university of St Andrews in 2000 where he remained as a postdoctoral research assistant for five years. In 2005 he was appointed to a lectureship at Aberystwyth University, and moved to the University of Central Lancashire in September 2009. He contributes to teaching in both physics and mathematics.

Daniel's research interests focus on dynamics events in the sun's atmosphere. He uses the latest observations from space-based observatories, such as NASA's Solar Dynamics Observatory, to study phenomena such as sunspots and X-ray bright points. He has also been involved in the calibration of the STEREO Heliospheric Imagers.

Daniel is actively involved with public engagement. He has promoted astrophysics at science exhibitions, including the Big Bang exhibition in Manchester 2010. He is also involved with public astronomy events at Alston Observatory.

Research

Rotating Sunspots: sunspots are dark patches in the Sun's surface where strong magnetic field from the solar interior protrudes into the atmosphere. Some sunspots are seen to rotate, twisting the atmospheric magnetic field which can lead to solar flares.

X-ray bright points: these are small loop structures observed in the Sun's atmosphere. They are relatively simple when compared to the larger, more complex active regions, so studying them can inform us about the basic magnetic processes that occur in the Sun's atmosphere.

Magnetic topology: The Sun's atmosphere is dominated by the magnetic field. This is not a simple north-south field like at the Earth, but a much more complex field with many different positive and negative poles. Modelling the Sun's magnetic field tells us how it is structured, and where dynamic restructuring of the field may take place.

Calibration of the STEREO Heliospheric Imagers: The stars in the background of the HI data can be used to determine the pointing and optical properties of the HI instruments, the photometric calibration and the large-scale flatfield of the HI instruments.
