The first ever search for the supersymmetric partner of the charm quark, led by Oxford graduate student Will Kalderon, has been selected by the ATLAS experiment at CERN as one of its physics highlights of the first run of the LHC.
In the first dedicated analysis of its kind, Will has completed an analysis of the ATLAS experiment's data searching for the proposed supersymmetric partner of the charm quark, the so-called “scalar-charm”. His analysis, which excluded low-mass scalar charm quarks, will be published in the next volume of Physical Review Letters.
The 11th Dennis Sciama Memorial Lecture will be delivered by Professor Philip Candelas, Mathematical Institute, University of Oxford.
Title: Simple Calabi-Yau Manifolds and the Landscape of String Vacua
Abstract: It is widely known that there are a great many vacua of string theory. A small subset of these lead to four-dimensional worlds that are somewhat like the world that we observe. The great majority lead to worlds very different from our own. A vacuum is determined by a Calabi-Yau manifold together with certain extra structure.
The Wetton Lecture will de delivered by Professor Carlo Frenk, Director, Institute for Computational Cosmology, University of Durham.
Title: "Everything from nothing, or how our universe was made"
Abstract: Cosmology confronts some of the most fundamental questions in the whole of science. How and when did our universe begin? What is it made of? How did galaxies and other structures form? There has been enormous progress in the past few decades towards answering these questions.

The Physics Department is sad to announce the death of Professor Roger Cowley.
Roger was Dr Lee’s Professor of Experimental Philosophy and Fellow of Wadham College from 1988 to 2007.
He served two spells as Chairman of Physics, from 1993 to 1996 and then from 1998 to 2002.
The 9th Hintze Lecture - Professor Scott Ransom - Millisecond Pulsars, Magnetars, and Black Holes: The Wickedly Cool Stellar Undead
Professor Scott Ransom US National Radio Astronomy Observatory will give the 9th Hintze Lecture.
"Millisecond Pulsars, Magnetars, and Black Holes: The Wickedly Cool Stellar Undead"
Abstract: The most massive stars burn the fastest and brightest and die spectacularly, exploding as supernovae and leaving behind some of the most fantastic objects in the Universe: neutron stars and black holes.

Each month, the American Physical Society's Committee for the Status of Women in Physics recognizes a female physicist who is making an impact in the physics community. Jena Meinecke, a graduate student in Atomic and Laser Physics, is October's Woman Physicist. Full story at http://www.aps.org/programs/women/scholarships/womanmonth/2014.cfm

Evidence has been accumulating for several decades that many galaxies harbor
central mass concentrations that may be in the form of black holes with masses
between a few million to a few billion time the mass of the Sun. I will discuss
measurements over the last two decades, employing adaptive optics imaging and
spectroscopy on large ground-based telescopes that prove the existence of such
a massive black hole in the Center of our Milky Way, beyond any reasonable

The discovery of three closely orbiting supermassive black holes in a galaxy more than four billion light years away could help astronomers in the search for gravitational waves: the ‘ripples in spacetime’ predicted by Einstein.
An international team, including Oxford University scientists, led by Dr Roger Deane from the University of Cape Town, examined six systems thought to contain two supermassive black holes.
"Development of an advanced scanning transmission electron microscope for material science research" by Dr Naoya Shibata, The University of Tokyo
Understanding the atomic-scale structures of surfaces and interfaces is essential to control the functional properties of many materials and devices. Recent advances in aberration-corrected scanning transmission electron microscopy (STEM) have made possible the direct characterization of localized atomic structures in materials, especially at interfaces.
