Multiple populations along the asymptotic giant branch of the globular cluster M 4
C. Lardo, M. Salaris, A. Savino +3
Nearly all Galactic globular clusters host stars that display characteristic abundance anti-correlations, like the O-rich/Na-poor pattern typical of field halo stars, together with…
The southern leading and trailing wraps of the Sagittarius tidal stream around the globular cluster Whiting1
Julio A. Carballo-Bello, Jesus M. Corral-Santana, David Martinez-Delgado +6
We present a study of the kinematics of 101 stars observed with VIMOS around Whiting1, a globular cluster embedded in the Sagittarius tidal stream. The obtained velocity distributi…
High-Dimensional Intra-City Quantum Cryptography with Structured Photons
Alicia Sit, Frédéric Bouchard, Robert Fickler +11
Quantum key distribution (QKD) promises information-theoretically secure communication, and is already on the verge of commercialization. Thus far, different QKD protocols have bee…
A Deconvolution Technique to Correct Deep Images of Galaxies from Instrumental Scattered Light
Emin Karabal, Pierre-Alain Duc, Harald Kuntschner +3
Deep imaging of the diffuse light emitted by the stellar fine structures and outer halos around galaxies is now often used to probe their past mass assembly. Because the extended h…
On-Chip Single-Photon Sifter
Ali W. Elshaari, Iman Esmaeil Zadeh, Andreas Fognini +5
Quantum states of light play a pivotal role in modern science[1] and future photonic applications[2]. While impressive progress has been made in their generation and manipulation w…
Polarization Gradient Study of Interstellar Medium Turbulence Using The Canadian Galactic Plane Survey
C. A. Herron, J. Geisbuesch, T. L. Landecker +5
We have investigated the magneto-ionic turbulence in the interstellar medium through spatial gradients of the complex radio polarization vector in the Canadian Galactic Plane Surve…
