Distances to molecular clouds at high galactic latitudes based on Gaia DR2
Qing-Zeng Yan,Qing-Zeng Yan,Bo Zhang,Ye Xu,Sufen Guo,Jean-Pierre Macquart,Zheng-Hong Tang,Andrew Walsh +7 more
TL;DR: In this article, the distances of molecular clouds at high Galactic latitudes (|b | > 10°) derived from parallax and G -band extinction (A G ) measurements in the second Gaia data release, Gaia DR2.

TL;DR: In this paper, Parkes et al. found that the PKS 1718-649 spectrum and its variability are best explained by variations in the free-free optical depth on our line of sight to the radio source at low frequencies (below the spectral peak) and the adiabatic expansion of the radio sources itself at high frequencies (above the peak).

TL;DR: In this paper, the authors used a sample of 104 fast radio bursts (FRBs) whose positions are localized to within one arcsecond, sufficient to obtain host galaxy redshifts via optical follow-up.

TL;DR: The Australian SKA Pathfinder (ASKAP) telescope has started to localize Fast Radio Bursts (FRBs) to arcsecond accuracy from the detection of a single pulse, allowing their host galaxies to be reliably identified as discussed by the authors.
Journal ArticleDOI
On detecting millisecond pulsars at the galactic center
TL;DR: In this article, the authors estimate the best search frequency for such an MSP population with present and upcoming broadband radio telescopes for two possible scattering scenarios, the "weak-scattering" case suggested by the recent detection of a magnetar close to the Galactic Center (GC) and the "strong" case, with the scattering screen located close to a GC.
