CHIME/FRB Discovery and Localization of the Swift-observed FRB 20241228A

The Astrophysical Journal
On 2024 December 28, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB project detected the thus-far nonrepeating FRB 20241228A with a real-time signal-to-noise ratio of >50.

A Very Long Baseline Interferometry Calibrator Grid at 600 MHz for Fast Radio Transient Localizations with CHIME/FRB Outriggers

The Astrophysical Journal
The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project has a new very long baseline interferometry (VLBI) Outrigger at the Green Bank Observatory (GBO), which forms a 3300 km baseline with CHIME operating at 400–800 MHz ...

The Peculiar Velocity of Messier 87 from Microarcsecond Geodetic Very Long Baseline Interferometry Astrometry

The Astrophysical Journal
Our knowledge of the space velocity of Messier 87, which is the dominant galaxy in the Virgo cluster, has been limited to the radial velocity component.

Prospects of Detecting a Jet in Sagittarius A* with Very-long-baseline Interferometry

The Astrophysical Journal
Event Horizon Telescope (EHT) images of the horizon-scale emission around the Galactic center supermassive black hole Sagittarius A* (Sgr A*) favor accretion flow models with a jet component. However, this jet has not been conclusively detected.

Evolution of the Termination Region of the Parsec-scale Jet of 3C 84 Over the Past 20 yr

The Astrophysical Journal
We present the kinematics of the parsec-scale jet in 3C 84 from 2003 November to 2022 June observed with the Very Long Baseline Array at 43 GHz. We find that the C3 component, a bright feature at the termination region of the jet component ejected from ...

VLBA Astrometry of the Galactic Double Neutron Stars PSR J0509+3801 and PSR J1930–1852: A Preliminary Transverse Velocity Distribution of Double Neutron Stars and its Implications

The Astrophysical Journal
The mergers of double neutron star (DNS) systems are believed to drive the majority of short γ -ray bursts (SGRBs), while also serving as production sites of heavy r -process elements.
