Relativistic X-ray jets at high redshift
Daniel A Schwartz, Aneta Siemiginowska, Diana M Worrall +6
Powerful radio sources and quasars emit relativistic jets of plasma and magnetic fields that travel hundreds of kilo-parsecs, ultimately depositing energy into the intra- or inter-…
Strong Confinment of optical fields using localised surface phonon polaritons in cubic Boron Nitride
Ioannis Chatzakis, Athith Krishna, James Culbertson +4
Phonon polaritons (PhPs) are long-lived electromagnetic modes that originate from the coupling of infrared photons with the bound ionic lattice of a polar crystal. Cubic-Boron nitr…
Detection of a gamma-ray flare from the high-redshift blazar DA 193
Vaidehi S. Paliya, M. Ajello, R. Ojha +10
High-redshift () blazars are the most powerful members of the blazar family. Yet, only a handful of them have both X-ray and -ray detection, thereby making it difficult to…
Spin-selective AC Stark shifts in a charged quantum dot
Tristan A. Wilkinson, Dillion J. Cottrill, Joshua M. Cramlet +6
A strong, far-detuned laser can shift the energy levels of an optically active quantum system via the AC Stark effect. We demonstrate that the polarization of the laser results in…
Water and OH Emission from the inner disk of a Herbig Ae/Be star
Steven C. Adams, Máté Ádámkovics, John S. Carr +2
We report the detection of hot HO and OH emission from the Herbig Ae/Be star HD using the Cryogenic Infrared Echelle Spectrograph on the $\textit{Very Large Telescop…
The Megaparsec-scale Gas-sloshing Spiral in the Remnant Cool Core Cluster Abell 1763
E. M. Douglass, E. L. Blanton, S. W. Randall +4
We present a multiwavelength study of the massive galaxy cluster Abell 1763 at redshift z = 0.231. Image analysis of a 19.6 ks Chandra archival observation reveals a cluster-wide s…
