Experimental Sensitivity Enhancement of a Quantum Rydberg Atom-Based RF Receiver with a Metamaterial GRIN Lens
Anton Tishchenko, Demos Serghiou, Ashwin Thelappilly Joy +6
We experimentally demonstrate enhanced sensitivity of an atom-based Rydberg radio frequency (RF) receiver integrated with a gradient refractive index (GRIN) Luneburg-type metamater…
White-light flares on cool stars in the Kepler Quarter 1 Data
Lucianne M. Walkowicz, Gibor Basri, Natalie Batalha +11
We present the results of a search for white light flares on the ~23,000 cool dwarfs in the Kepler Quarter 1 long cadence data. We have identified 373 flaring stars, some of which…
The Impact of the Convective Blueshift Effect on Spectroscopic Planetary Transits
Avi Shporer, Tim Brown
We present here a small anomalous radial velocity (RV) signal expected to be present in RV curves measured during planetary transits. This signal is induced by the convective blues…
Prediction of SINR using BER and EVM for Massive MIMO Applications
Tim Brown, David Humphreys, Martin Hudlicka +1
Future communication systems employing massive multiple input multiple output will not have the ability to use channel state information at the mobile user terminals. Instead, it w…
Photometric Variability in Kepler Target Stars: The Sun Among Stars -- A First Look
Gibor Basri, Lucianne M. Walkowicz, Natalie Batalha +10
The Kepler mission provides an exciting opportunity to study the lightcurves of stars with unprecedented precision and continuity of coverage. This is the first look at a large sam…
On using the beaming effect to measure spin-orbit alignment in stellar binaries with Sun-like components
Avi Shporer, Tim Brown, Tsevi Mazeh +1
The beaming effect (aka Doppler boosting) induces a variation in the observed flux of a luminous object, following its observed radial velocity variation. We describe a photometric…
