Imaging without visibilities: FAST-Effelsberg scintillometry of PSR B1508+55
Tim Sprenger, Xun Shi, Olaf Wucknitz +1
Context. The spatially coherent multipath propagation of pulsar radiation leads to a temporal and spectral interference patterns called scintillation. It is caused by density varia…
The promising future of a robust cosmological neutrino mass measurement
Thejs Brinckmann, Deanna C. Hooper, Maria Archidiacono +2
We forecast the sensitivity of thirty-five different combinations of future Cosmic Microwave Background and Large Scale Structure data sets to cosmological parameters and to the to…
INR meets Multi-Contrast MRI Reconstruction
Natascha Niessen, Carolin M. Pirkl, Ana Beatriz Solana +6
Multi-contrast MRI sequences allow for the acquisition of images with varying tissue contrast within a single scan. The resulting multi-contrast images can be used to extract quant…
Two new highly scattered fast radio bursts: evidence for scatter broadening by the circumsource medium
Joscha N. Jahns-Schindler, Keith W. Bannister, Adam T. Deller +17
We found two highly scattered Fast Radio Bursts (FRBs) during commissioning of the Commensal Realtime ASKAP Fast Transient COherent (CRACO) backend. FRB 240210D and FRB 240312D hav…
Scintillometry of Fast Radio Bursts: Resolution effects in two-screen models
Sachin Pradeep E. T, Tim Sprenger, Olaf Wucknitz +2
Fast Radio Bursts (FRBs) exhibit scintillation and scattering, often attributed to interactions with plasma screens in the Milky Way and the host galaxy. When these two screens app…
Interstellar Interferometry: Precise Curvature Measurement from Pulsar Secondary Spectra
Daniel Baker, Walter Brisken, Marten H. van Kerkwijk +4
The parabolic structure of the secondary or conjugate spectra of pulsars is often the result of isolated one-dimensional (or at least highly anisotropic) lenses in the ISM. The cur…
