Professor Matt Griffin of the School of Physics and Astronomy at Cardiff University will describe the prospects for observations of distant galaxies in his talk on Monday 9 July at the ‘From IRAS to Herschel and Planck’ conference at the Geological Society in London. The meeting is being held to celebrate the 65th birthday of Royal Astronomical Society President Professor Michael Rowan-Robinson, who has been a leading figure in infrared astronomy for the last three decades.
Herschel is named after the British astronomer William Herschel, who made the first detection infrared radiation in 1800, some 19 years after he discovered the planet Uranus. It will be the largest astronomical telescope yet flown in space, with a diameter of 3.5 metres, and will carry three sophisticated scientific instruments - SPIRE (the Spectral and Photometric Imaging Receiver), HIFI (the Heterodyne Instrument for the Far Infrared) and PACS (Photodetector Array Camera and Spectrometer). These are designed to view the Universe in the far infrared and sub-millimetre wavelength bands that cannot be seen from the ground because this radiation cannot penetrate the Earth's atmosphere to reach the ground.
Large galaxies like our own are thought to have formed in the past by the merging of smaller galaxies. These mergers usually caused intense episodes of star formation in the new galaxy, the signs of which can best be observed in the far infrared part of the spectrum. This is because star formation occurs deep inside clouds of gas and dust from which no visible light can emerge - but far infrared light can get out, carrying with it the signatures of what's going on inside. When astronomers observe very distant objects, they see them as they were a long time ago, so by observing galaxies at very large distances, Herschel will show us how they formed as a result of these cosmic collisions.
Closer to home, Herschel's instruments will be used to study in great detail how stars and planetary systems continue to form in our own galaxy today, and to investigate the planets, comets and satellites of our own Solar System.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
