The RRAT Trap: Interferometric Localization of Radio Pulses from J0628+0909
, 2012 We present the first blind interferometric detection and imaging of a millisecond radio transient with an observation of transient pulsar J0628+0909. We developed a special observing mode of the Karl G. Jansky Very Large Array (VLA) to produce correlated

Cosmography from well-localized fast radio bursts
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances that have emerged as prominent cosmological probes due to their dispersion measure (DM) evolution with redshift. In this work, we use cosmography, a model-independent approach to describe the evolution of the Universe, to introduce the ...

Radio Frequency Selective Addressing of Localized Particles in a Periodic Potential
, 2004 We study the localization and addressability of ultra cold atoms in a combined parabolic and periodic potential. Such a potential supports the existence of localized stationary states and we show that using a radio frequency field allows to selectively ...
