ORIGIN: metal creation and evolution from the cosmic dawn

Alexey Boyarsky, Douglas Cameron Watson, Oleg Ruchayskiy, Simone Campana

ORIGIN is a proposal for the M3 mission call of ESA aimed at the study of metal creation from the epoch of cosmic dawn. Using high-spectral resolution in the soft X-ray band, ORIGIN will be able to identify the physical conditions of all abundant elements ...

Can a Metal Surface Repel Electric Charges?

Primoz Rebernik Ribic

We show that the interaction between a surface and a charge packet moving parallel to it can become repulsive above a critical relativistic energy. We find that this is true for a lossless dielectric surface and also for a Drude metallic surface-in apparen ...

CMB photons shedding light on dark matter

Julien Lesgourgues, Benjamin Audren, Gaëlle Giesen

The annihilation or decay of Dark Matter (DM) particles could affect the thermal history of the universe and leave an observable signature in Cosmic Microwave Background (CMB) anisotropies. We update constraints on the annihilation rate of DM particles in ...

Mode tuning of photonic crystal nanocavities by photoinduced non-thermal oxidation

Laurent Balet, Massimo Gurioli, Santosh Kumar

A method to achieve photoinduced tuning of PhC nanocavity modes is discussed and implemented. It is based on light induced oxidation in air atmosphere with very low thermal budget which produces a local reduction of the GaAs membrane effective thickness an ...

Evolution of the observed Ly alpha luminosity function from z=6.5 to z=7.7: evidence for the epoch of reionization?

Jean-Paul Richard Kneib, Frédéric Courbin, Benjamin Yvan Alexandre Clement

Aims. Ly alpha emitters (LAEs) can be detected out to very high redshifts during the epoch of reionization. The evolution of the LAE luminosity function with redshift is a direct probe of the Ly alpha transmission of the intergalactic medium (IGM), and the ...

Gravitational radiation in Horava gravity

Hillary Sanctuary, Diego Blas Temino

We study the radiation of gravitational waves by self-gravitating binary systems in the low-energy limit of Horava gravity. We find that the predictions for the energy-loss formula of general relativity are modified already for Newtonian sources: the quadr ...

Reduced Basis Catalogs for Gravitational Wave Templates

Jan Sickmann Hesthaven

We introduce a reduced basis approach as a new paradigm for modeling, representing and searching for gravitational waves. We construct waveform catalogs for nonspinning compact binary coalescences, and we find that for accuracies of 99% and 99.999% the met ...

Rolling Ribbons

Pedro Miguel Nunes Pereira de Almeida Reis, John Bush

We present the results of a combined experimental and theoretical investigation of rolling elastic ribbons. Particular attention is given to characterizing the steady shapes that arise in static and dynamic rolling configurations. In both cases, above a cr ...
