Carbon and nitrogen abundances of individual stars in the Sculptor dwarf spheroidal galaxy

We present [C/Fe] and [N/Fe] abundance ratios and CH(lambda 4300) and S(lambda 3883) index measurements for 94 red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy from VLT/VIMOS MOS observations at a resolving power R = 1150 at 4020 A. Thi ...

Intense THz source based on BNA organic crystal pumped at Ti:sapphire wavelength

Mostafa Shalaby, Christoph Peter Hauri

We report on high-energy terahertz pulses by optical rectification (OR) in the organic crystal N-benzyl-2-methyl-4-nitroaniline (BNA) directly pumped by a conventional Ti:sapphire amplifier. The simple scheme provides an optical-to-terahertz conversion eff ...

Planck intermediate results XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes

Julien Lesgourgues, Fabio Finelli

The polarized thermal emission from diffuse Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 100 GHz. In this paper we exploit the uniqueness of the Planck HFI po ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Julien Perruisseau-Carrier, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Intense, carrier frequency and bandwidth tunable quasi single-cycle pulses from an organic emitter covering the Terahertz frequency gap

Christoph Peter Hauri

In Terahertz (THz) science, one of the long-standing challenges has been the formation of spectrally dense, single-cycle pulses with tunable duration and spectrum across the frequency range of 0.1–15 THz (THz gap). This frequency band, lying between the el ...

Demonstration of a low-frequency three-dimensional terahertz bullet with extreme brightness

Mostafa Shalaby, Christoph Peter Hauri

The brightness of a light source defines its applicability to nonlinear phenomena in science. Bright low-frequency terahertz (

Spectrally intense terahertz source based on triangular Selenium

Mostafa Shalaby, Christoph Peter Hauri

The intensity of a nonlinear terahertz (THz) source is primarily given by its spectral density. In this letter, we introduce triangular Selinium (Se) as a novel THz emitter and show numerically its superior properties to the currently used crystals for int ...
