The Astroparticle and High Energy Physics Group at the Instituto de Fisica Corpuscular (a Severo Ochoa Excellence Center) of the University of Valencia and CSIC announces a student grant to perform a PhD Thesis in Theoretical Particle Physics, under the Spanish PhD programme Formación de Personal Investigador (FPI-Severo Ochoa). The call has been published by the Spanish Ministry of Economy and Competitiveness (MINECO), see link below. The candidate should have experience equivalent to a Master Degree at the beginning of the appointment. He/she should perform research towards a PhD Thesis in one of the group research lines,
Neutrino properties: laboratory and astrophysics
Neutrino masses, origin and implications
New physics at the Large Hadron Collider after the Higgs boson
Particle cosmology: neutrinos and dark matter
These four research lines are interconnected and cover theoretical, phenomenological and observational aspects of Astroparticle and High Energy Physics. Please send your curriculum vitae, certificate of undergraduate grades, Master degree certificate or equivalent together with at least one letter of recommendation to the address below, BEFORE September 21, 2016.

Durante casi un siglo, los científicos hemos ido encontrando evidencia cada vez más sólida de que hay materia en el Universo más allá de la que observamos directamente con la luz. Sabemos que esta materia, a la que llamamos «oscura» precisamente porque no interacciona con la luz, compone el 80% de la materia del Universo. Sabemos también que interacciona gravitatoriamente (así es como hemos deducido su existencia) y que no está formada por las partículas que conocemos. Es, por tanto, uno de los grandes misterios de la Física actual.

Crosstalk and transitions between multiple spatial maps in an attractor neural network model of the hippocampus: Phase diagram

Researchers at the École Normale Supérieure in Paris have simulated the behavior of networks of “place cells” that store memories of location and spatial maps in the brain. In additional to revealing that some noise (but not too much) in the network can improve its storage capacity, the authors find that encoding too many spatial maps in the network may cause the memories to slip away entirely.

Black holes and pulsars emit dense jets of particles that are made of electrons and positrons (the antiparticle of the electron). But many important and basic features of the jets remain unclear: What is their precise particle makeup? How much energy do they contain? How do the particles in the jets interact in the low-density environment of outerspace? The main difficulty in answering these questions is that astronomical systems can only be measured indirectly: the closest jet is almost 1024 miles away. As Gianluca Sarri from The Queen’s University of Belfast, Northern Ireland, and colleagues report in Physical Review Letters, a new tabletop method for generating electron-positron streams could bring measurements closer to home by enabling the scaled-down reproduction of matter-antimatter flows in the lab.

JEM-EUSO is a new type of observatory that uses the earth's atmosphere as a detector. JEM-EUSO will be on orbit on the International Space Station (ISS). It observes transient luminous phenomena taking place in the earth's atmosphere caused by particles coming from space. The sensor is a super wide-field telescope that detects extreme energy particles with energy above 3×1019 eV. This remote-sensing instrument orbits around the earth every 90 minutes on board of the International Space Station at the altitude of approximately 400km (Figure 1-1). The figure shows an extreme energy particle colliding with a nucleus in the earth's Atmosphere, where it produces an Extensive Air Shower (EAS), consisting of numerous electrons, positrons, and photons. JEM-EUSO captures the moving track, which is revealed by the fluorescent UV photons and reproduces the energy development of the EAS.
