Relativistic X-ray jets at high redshift

Kavli Affiliate: Herman Marshall | First 5 Authors: Daniel A Schwartz, Aneta Siemiginowska, Diana M Worrall, Mark Birkinshaw, Teddy Cheung | Summary: 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-cluster medium. In the rest frame of the […]

Geometric Satake correspondence for affine Kac-Moody Lie algebras of type $A$

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Hiraku Nakajima, , , , | Summary: This is an informal expository article on geometric Satake correspondence for affine Kac-Moody Lie algebras of type $A$ given in arXiv:1810.04293. We emphasize formal analogies between this result and the author’s earlier results on geometric approaches to the representation via […]

Optical coherence of diamond nitrogen-vacancy centers formed by ion implantation and annealing

Kavli Affiliate: Tim H. Taminiau | First 5 Authors: Suzanne B. van Dam, Michael Walsh, Maarten J. Degen, Eric Bersin, Sara L. Mouradian | Summary: The advancement of quantum optical science and technology with solid-state emitters such as nitrogen-vacancy (NV) centers in diamond critically relies on the coherence of the emitters’ optical transitions. A widely […]

Room temperature optomechanical squeezing

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Nancy Aggarwal, Torrey Cullen, Jonathan Cripe, Garrett D. Cole, Robert Lanza | Summary: The radiation-pressure driven interaction of a coherent light field with a mechanical oscillator induces correlations between the amplitude and phase quadratures of the light. These correlations result in squeezed light — light with quantum […]

Electrically Driven, Optically Levitated Microscopic Rotors

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Alexander D. Rider, Charles P. Blakemore, Akio Kawasaki, Nadav Priel, Sandip Roy | Summary: We report on the electrically driven rotation of $2.4~mu$m-radius, optically levitated dielectric microspheres. Electric fields are used to apply torques to a microsphere’s permanent electric dipole moment, while angular displacement is measured by […]

Test of the Gravitational Redshift with Galileo Satellites in an Eccentric Orbit

Kavli Affiliate: Sven Herrmann | First 5 Authors: Sven Herrmann, Felix Finke, Martin Lülf, Olga Kichakova, Dirk Puetzfeld | Summary: On August 22, 2014, the satellites GSAT-0201 and GSAT-0202 of the European GNSS Galileo were unintentionally launched into eccentric orbits. Unexpectedly, this has become a fortunate scientific opportunity since the onboard hydrogen masers allow for […]

Electrical control of interlayer exciton dynamics in atomically thin heterostructures

Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Luis A. Jauregui, Andrew Y. Joe, Kateryna Pistunova, Dominik S. Wild, Alexander A. High | Summary: Excitons in semiconductors, bound pairs of excited electrons and holes, can form the basis for new classes of quantum optoelectronic devices. A van der Waals heterostructure built from atomically thin […]

Forecasting [C II] line-intensity mapping measurements between the end of reionization and the epoch of galaxy assembly

Kavli Affiliate: Sarah E. Church | First 5 Authors: Dongwoo T Chung, Marco P Viero, Sarah E Church, Risa H Wechsler, | Summary: We combine recent simulation work on the SFR–[C II] correlation at high redshift with empirical modeling of the galaxy–halo connection (via UniverseMachine) to forecast [C II] auto power spectra from $zsim4$ to […]

The ultra-diffuse galaxy NGC 1052-DF2 with MUSE: II. The population of DF2: stars, clusters and planetary nebulae

Kavli Affiliate: Eric Peng | First 5 Authors: Jeremy Fensch, Remco F. J. van der Burg, Tereza Jerabkova, Eric Emsellem, Anita Zanella | Summary: NGC 1052-DF2, an ultra diffuse galaxy (UDG), has been the subject of intense debate. Its alleged absence of dark matter, and the brightness and number excess of its globular clusters (GCs) […]
