A sudden dramatic change and recovery of magneto-environment of a repeating fast radio burst
Y. Li, S. B. Zhang, Y. P. Yang +35
Fast radio bursts (FRBs) are millisecond-duration radio bursts with unidentified extra-galactic origin. Some FRBs exhibit mild magneto-ionic environmental variations, possibly attr…
Flat tails in FRB and pulsar energy distributions: implications for optimizing nearby FRB surveys
S. B. Zhang, G. Hobbs, S. Johnston +6
Fast radio bursts (FRBs) are energetic, short-duration radio pulses of unclear origin. To explore effective survey strategies for detecting FRBs from nearby globular clusters (GCs)…
Parkes transient events: II. Pulsar single pulses database containing raw data segment
Xuan Yang, S. B. Zhang, Le-Yu Tang +2
We have re-processed single pulse candidates from the first four years (1997-2001) of the Parkes Multibeam receiver system observations, creating a new Parkes transient database (P…
Searching for radio pulsars in old open clusters from the Parkes archive
S. B. Zhang, J. J. Wei, X. Yang +7
Motivated by the discovery of a pulsar in the direction of the old open cluster NGC 6791, we conducted a search for radio pulsars in archival Parkes observations targeting similar…
Shock-induced HCNH+ abundance enhancement in the heart of the starburst galaxy NGC 253 unveiled by ALCHEMI
Y. Gong, C. Henkel, C. T. Bop +15
Understanding the chemistry of molecular clouds is pivotal to elucidate star formation and galaxy evolution. As one of the important molecular ions, HCNH+ plays an important role i…
A universal break in energy functions of three hyperactive repeating fast radio bursts
Q. Wu, F. Y. Wang, Z. Y. Zhao +16
Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances with a mysterious origin. Observations show that at least some FRBs are produced by mag…
