Congrats to Prof Hendry MBE

Congratulations to Professor Martin Hendry for being awarded an MBE in the New Year Honours List for services to Public Engagement in Science.







First NuSTAR image of the Sun


Above is the first image of the Sun taken by NASA’s X-ray telescope NuSTAR. The blue and green are NuSTAR X-rays in 2-3 keV and 3-5 keV, overlaid onto EUV emission from SDO/AIA (red). This image was recently released and has featured on many news sites (BBC, Time, National Geographic, etc) and made it to the Astronomy picture of the day. A&A’s Dr. Iain Hannah and Dr. Hugh Hudson are part of the NuSTAR solar team that is using this X-ray telescope, that normally looks at distant blackholes, to probe faint signatures of heating and particle acceleration in the solar atmosphere.

Lunar Mission One

This is a unique opportunity to get involved in lunar exploration. In addition the the drilling and the archive we hope to include a simple radio receiver on the lander,  which can be used to study the Moon’s tenuous exosphere and maybe even do some radio astronomy. For details of how to get involved see the Lunar Mission One homepage.

PhD student paper wins Scottish prize


Congratulations to David Graham, whose paper “The Emission Measure Distribution of Impulsive Phase Flare Footpoints“, published while he was a PhD student in the A&A group, has won this year’s Robert Cormack Bequest Postgraduate Prize. This prize, awarded annually by the Royal Society of Edinburgh, is for the best nominated paper accepted for publication in 2013/14 with a postgraduate in a Scottish Institution as prime author. David gets a cheque for a helpful sum, and an invitation to speak to the annual Cormack Astronomy Meeting in November.

The paper investigates the temperature distribution of the plasma produced in the lower atmosphere (footpoints) of a flare during the phase of primary energy injection, finding a distribution peaking at 10MK and with a slope consistent with thermal conduction. It is the first time that the properties of flare footpoints have been investigated in this way. Co-authors were Iain G. Hannah, Lyndsay Fletcher (both GU) and Ryan O. Milligan (Queen’s University Belfast)

Well done David!

Glasgow Sun

As we are heading through solar maximum there are several sunspots and filaments visible on the solar disk. The image below was obtained on the ground in Glasgow, taken by two undergraduate students (Peter Wakeford and Ruari MacKenzie) using an H-alpha telescope at our Acre Road Observatory.

THEMIS telescope building

THEMIS telescope building

Two solar scientists from the Glasgow group are currently observing the Sun with the THEMIS telescope at the Observatorio del Teide on the Island of Tenerife.

Dr Nicolas Labrosse and PhD student Peter Levens are leading an international team which has been awarded 20 days of observing time with THEMIS as part of the SOLARNET Transnational Access and Service Programme.

These observations will be part of a larger observing campaign in coordination with other instruments, including more ground-based observatories (Solar Tower of Observatoire de Meudon, Fuxian Solar Observatory) and satellites (SDO, Hinode, IRIS).

The objective is the measurement of magnetic fields in prominences and tornadoes, exploiting the excellent spectro-polarimetric capabilities of THEMIS in the He D3 line to infer the magnetic field vector. These phenomena represent unique examples of the small-scale coupling between magnetic field and plasma in environments with distinct dynamical behaviour. As such they represent key case studies for deepening our understanding of the Sun.

Peter Levens is pointing the telescope on an attractive target.

Major funding boost to A&A group

The A&A group receives a major boost with funding from the European Commission’s Seventh Framework Programme (FP7) for space-related research.

A powerful X-class flare observed by Hinode’s Solar Optical Telescope (SOT) on Dec. 13, 2006

Dr. Lyndsay Fletcher and Dr Nicolas Labrosse from the Astronomy & Astrophysics group in the School of Physics and Astronomy will investigate the physics of solar flares.

The F-CHROMA project (Flare CHRomospheres: Observations, Models and Archives) will bring together experts from seven institutions to collect, synthesise and analyse data from satellite and earthbound observations of solar flares. Solar flares are energetic outbursts of solar radiation which span the whole electromagnetic spectrum. Mid-sized flares can release energy equivalent to a hundred million megatons of TNT in just a few minutes, most of which ultimately turns into electromagnetic radiation. This radiation is emitted primarily by a thin, and complicated, part of the Sun’s atmosphere called the chromosphere.

Lyndsay Fletcher, Principal Investigator, said that this project will allow the team to combine ultra-high detail observation of solar flare events with advanced theoretical and computational modeling to shed light on the way a flare’s energy is stored, released, and converted into other forms.

The outcomes of F-CHROMA will be used to inform preparations for major forthcoming projects including the Daniel K. Inouye Solar Telescope which will see first light in 2019 in Hawai’i and ESA’s Solar Orbiter Mission which is expected to start beaming back solar images and spectra from its orbit in the inner solar system at around the same time.

F-CHROMA is one of two projects led by the University of Glasgow receiving funding from the European Commission.

Galina Motorina, a winner of the all-Russia competition, was awarded a scholarship of the President of the Russian Federation to pursue solar flare research in Glasgow. The awards are for PhD students who “achieved considerable success in fundamental or applied researches”.

Ionospheric perturbations ‘decorated’ solar radio dynamic spectrum observed in December

Ionospheric perturbations strongly affect radio propagation, and can produce rather peculiar patterns in the dynamic spectra of solar radio emission (for details – see the paper Meyer-Vernet, N., Daigne, G., and Lecacheux, A., Astronomy and Astrophysics, 1981). Such unusual patterns can be seen in Glasgow radio data as well – see images and the radio data from other radio observatories (CALLISTO status report/news letter #47):

Dr. Iain Hannah – new Royal Society University Research Fellow

We congratulate Dr‌ Iain Hannah from our group who has taken up his post as one of 41 new Royal Society University Research Fellows (URFs) for 2013, to conduct a research programme into the physics of high energy solar flares. The University Research Fellowship scheme aims to provide outstanding scientists, who have the potential to become leaders in their chosen fields, with the opportunity to build an independent research career. Iain’s research into solar flares involves X-ray imaging and spectroscopy, multi-wavelength studies, statistical surveys and numerical simulations.

Big solar flares caught in Glasgow

GLASGOW_20131025_150000_59.fitThe recent flurry of solar activity has seen several large flares emitted by the Sun. The rapid release of energy in the Sun’s atmosphere heats material and accelerates particles resulting in bright emission seen by a myriad of satellite’s including NASA’s RHESSI. These were also caught by the solar radio telescope at our Acre Rd Observatory, which observes the electrons accelerated to high energies in flares. Our telescope uses a CALLISTO spectrometer and it provides live observations of the Sun at radio frequencies between 45 and 80 MHz with 0.125 second cadence. This strong radio emission can interrupt communications on the ground across many frequencies.

Glasgow Solar Physicists Honoured by NASA

rhessi_team_collage_2013In July the Science and Data Analysis Team working on NASA’s RHESSI satellite was honoured with a NASA Group Achievement Award. Of the 40 members of the team, 9 have strong links with Glasgow University, being current staff members and/or past PhD graduates in Solar Physics. The strong Glasgow representation in this international team builds on the early seminal work of Professor John C. Brown, ex Regius Chair in Astronomy in the School of Physics and Astronomy. The award was made in recognition of the team’s sustained, outstanding scientific achievement over a full solar cycle.

SDO/AIA images of a filament on the sun from August 31, 2012. From upper left and going clockwise: 335, 171, 304 and 131 Å channels

Registration is now open for the Royal Astronomy Society Specialist Discussion Meeting devoted to solar prominences on Friday 21st February in the RAS premises in London, UK. Abstracts can be submitted at the meeting web page.

This specialist discussion meeting aims to review our current understanding of the life-cycle of solar prominences. How do they form? How do they interact with their environment, from the photosphere to the corona? How do they disappear? What is their contribution to Space Weather? Addressing these questions relies on interactions between experts in plasma physics, MHD, magnetic field modelling and observation, spectroscopy, radiation transfer, … This will be an excellent opportunity to discuss open issues in this area of interest to solar and stellar physicists, keeping in mind recent and future developments in observations and in modelling.

500 years of Glasgow Astronomy

Dr David Clarke (Honorary Research Fellow and ex-Observatory Director) has written a book on the history of astronomy in Glasgow titled “Reflections on the Astronomy of Glasgow: A story of some 500 years” (Edinburgh University Press). In it David describes how astronomy contributed to the educational enlightenment of Glasgow and to its society and commerce.

The book is available at a special price from Edinburgh University Press till 30-Sep-2013 via this form and is also available on amazon.

How Astronomy contributed to the educational enlightenment of Glasgow, to its society and to its commerce

The book provides a comprehensive narrative concerning Glasgow’s connections with Astronomy since the University’s establishment in 1451. It covers the educational and scientific contributions of notable and sometimes notorious individuals, providing biographies of outstanding people, including George Sinclair, the Professors Dick , the Professors Wilson, James Watt, John Pringle Nichol, Robert Grant, Ludwig Becker and William Smart. Through such people, discoveries related to sunspots, the monochromaticity within light, the behaviour of dew-point and the discovery of infra-red radiation remarkably have Glasgow connections.

The early part nineteenth century saw a thirst for astronomical knowledge by the local population with the establishment of two public observatories in the City. The second was rescued financially by the University in 1845 with a remit for establishing a time service for shipping on the Clyde. Following ‘Glasgow’s Big Bang of 1863’, with an unwarranted Edinburgh intrusion for establishing a time-gun, the resulting spat was covered in heated exchanges in the Herald with the editor demeaning of the title of Astronomer Royal for Scotland; in the end the local Horselethill Observatory won out to provide telegraphic time signals for the control of City public clocks. The establishment of eight different observatories is described with details of their architecture.

Overall, the story is a collection of local material and its relationship to the general development of the subject of astronomy, with insights on commercial and social aspects, so supporting a unique picture of astronomical connections with the City of Glasgow.

Group research selected for journal cover image

A figure from a recent published paper by group members was chosen as cover image for this month’s volume of the Astronomy & Astrophysics journal. The image shows a map of heated plasma ejected from the corona and the paper (Hannah & Kontar, A&A v553 A10 2013) is focused on a method to obtain maps of the emission as a function of temperature from observations of a coronal mass ejection (CME) observed by NASA’s SDO/AIA.

Auroras Shine Light On Solar Flares — Group Research in University News

Solar flares are huge cosmic blasts of UV light, X-rays and high-energy particles from the Sun that can damage power grids and satellites. Inspired by the Northern Lights, Dr Alexander Russell and Dr Lyndsay Fletcher have shown how magnetic waves could help move energy tens of thousands of kilometres in less than a second to power flares.
