Superdiffusive transport in laboratory and astrophysical plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

In the last few years it has been demonstrated, both by data analysis and by numerical simulations, that the transport of energetic particles in the presence of magnetic turbulence can be superdiffusive rather than normal diffusive (Gaussian). The term ‘su ...

The dynamical and chemical evolution of dwarf spheroidal galaxies with GEAR

Pascale Jablonka, Yves Revaz

We present the fully parallel chemo-dynamical Tree/SPH code GEAR, which allows us to perform high resolution simulations with detailed chemical diagnostics. Starting from the public version of Gadget-2, we included the complex treatment of the baryon physi ...

Novel technique for supernova detection with IceCube

Mathieu Ribordy

The current supernova detection technique used in IceCube relies on the sudden deviation of the summed photomultiplier noise rate from its nominal value during the neutrino burst, making IceCube a approximate to 3 Megaton effective detection volume - class ...

Neutrino Analysis Of The 2010 September Crab Nebula Flare And Time-Integrated Constraints On Neutrino Emission From The Crab Using Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present the results of a search for high-energy muon neutrinos with the IceCube detector in coincidence with the Crab Nebula flare reported on 2010 September by various experiments. Due to the unusual flaring state of the otherwise steady source we perf ...

Constraints on high-energy neutrino emission from SN 2008D

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

SN 2008D, a core collapse supernova at a distance of 27 Mpc, was serendipitously discovered by the Swift satellite through an associated X-ray flash. Core collapse supernovae have been observed in association with long gamma-ray bursts and X-ray flashes an ...

The Cas A-Like Snr 1E 0102.2-7219 In The Small Magellanic Cloud: An Asymmetric Bipolar Explosion

Frédéric Vogt

We have used the Wide Field Spectrograph on the 2.3 m telescope at Siding Spring Observatory to map the [O III] lambda 5007 dynamics of the young oxygen-rich supernova remnant 1E 0102.2-7219 in the Small Magellanic Cloud. From the resultant data cube, we h ...

The origin of short-lived radionuclides and the astrophysical environment of solar system formation

Anders Meibom

Based on early solar system abundances of short-lived radionuclides (SRs), such as Al-26 (T-1/2 = 0.74 Myr) and Fe-60 (T-1/2 1.5 Myr), it is often asserted that the Sun was born in a large stellar cluster, where a massive star contaminated the protoplaneta ...

The oxygen isotopic composition of the Sun as a test of the supernova origin of Al-26 and Ca-41

Anders Meibom

Short-lived radionuclides were present in the solar protoplanetary disk in abundances much higher than in the ambient interstellar medium and require a last minute origin. Al-26 (T-1/2 = 0.73 Myr) and Ca-41 (T-1/2 = 0.1 Myr) abundances in the protoplanetar ...

The peroxisome proliferator activated receptors (PPARS) and their effects on lipid metabolism and adipocyte differentiation

Johan Auwerx, Kristina Schoonjans

The three types of peroxisome proliferator activated receptor (PPAR), alpha, beta (or delta), and gamma, each with a specific tissue distribution, compose a subfamily of the nuclear hormone receptor gene family. Although peroxisome proliferators, including ...
