Low-energy Radio Bursts from Magnetar XTE J1810−197: Implications for Fast Radio Bursts
The Astrophysical JournalMagnetars are the leading candidate sources of fast radio bursts (FRBs). However, the observational probes of the connections between magnetars and FRBs are severely limited by the paucity of detection of highly energetic radio events from magnetars—to ...

The Astrophysical Journal, 2023 It is recognized that some core-collapse supernovae (SNe) show a double-peaked radio light curve within a few years since the explosion. A shell of circumstellar medium (CSM) detached from the SN progenitor has been considered to play a viable role in ...

The Astrophysical JournalThe radiation physics of gamma-ray bursts (GRBs) remains an open question. Based on the simulation analysis and recent observations, it was proposed that GRB jets are composed of a narrow ultrarelativistic core surrounded by a wide subrelativistic cocoon.

Distinguishing coherent and thermal photon noise in a circuit QED system [PDF]
, 2018 In the cavity-QED architecture, photon number fluctuations from residual cavity photons cause qubit dephasing due to the AC Stark effect. These unwanted photons originate from a variety of sources, such as thermal radiation, leftover measurement photons,

The Astrophysical JournalThe radiation physics of bright prompt optical emission of gamma-ray bursts (GRBs) remains a puzzle. Assuming that the GRB ejecta is structured, we investigated this issue by characterizing the ejecta as an ultrarelativistic uniform jet core surrounded ...

Magnetic Interactions in White Dwarf Binaries as Mechanism for Long-period Radio Transients
The Astrophysical JournalA growing population of long-period radio transients has been discovered, and their physical origin is still up for debate. Recently, a new such source named ILT J1101+5521 was discovered, which is in a white dwarf (WD)–red dwarf (RD) binary system, with

Radiative Processes In Extragalactic Large-Scale Jets [PDF]
, 2005 About one thousand extragalactic large-scale jets are known, and a few tens of them are confirmed sources of infrared, optical, or X-ray photons. Multiwavelength emission comming directly from these outflows is always non-thermal in origin.

Spatial Distribution of Secondary Electrons’ Synchrotron Emission: Property and Implication
The Astrophysical JournalGalactic γ -ray sources can be produced by either high-energy protons via proton–proton collisions or electrons/positrons via inverse Compton scattering.

NuSTAR Observations of Abell 665 and 2146: Constraints on Nonthermal Emission
The Astrophysical Journal, 2023 Observations from past missions such as RXTE and Beppo-SAX suggested the presence of inverse Compton (IC) scattering at hard X-ray energies within the intracluster medium of some massive galaxy clusters. In subsequent years, observations by, e.g., Suzaku,

The Astrophysical JournalMultimessenger observations suggest that the gamma-ray burst on 2017 August 17 (GRB 170817A) resulted from off-axial observations of its structured jet, which consists of a narrow ultrarelativistic jet core surrounded by a wide mild-relativistic cocoon ...
