Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope
Hendrik Mueller, Sebastiano D. von Fellenberg, Ai-Ling Zeng +275
The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact…
Discovery of a 21 cm absorption system at z=2.327 with CHIME
CHIME Collaboration, Mandana Amiri, Arnab Chakraborty +19
We report the detection of a new 21 cm absorption system associated with the radio source NVSS J164725+375218 at a redshift of z=2.327, identified through a pilot survey conducted…
Transient Blurring of the Scintillation Arc of Pulsar B1737+13
Yen-Hua Chen, Samuel Siegel, Daniel Baker +2
For many pulsars, the scattering structures responsible for scintillation are typically dominated by a single, thin screen along the line of sight, which persists for years or deca…
The FAST HI 21-cm absorption blind survey. II. -- Statistic Exploration for Associated and Intervening systems
Wenkai Hu, Yougang Wang, Yichao Li +12
We present an extragalactic HI 21-cm absorption lines catalog from a blind search at z 0.35, using drift-scan data collected in 1325.6 hours by the ongoing Commensal Ra…
Refractive lensing of scintillating FRBs by sub-parsec cloudlets in the multi-phase CGM
Dylan L. Jow, Xiaohan Wu, Ue-Li Pen
We consider the refractive lensing effects of ionized cool () gas cloudlets in the circumgalactic medium (CGM) of galaxies. In particular, we discuss the comb…
First M87 Event Horizon Telescope Results. III. Data Processing and Calibration
The Event Horizon Telescope Collaboration
We present the calibration and reduction of Event Horizon Telescope (EHT) 1.3mm radio wavelength observations of the supermassive black hole candidate at the center of the radio ga…
