The Astrophysical JournalMeasuring the 3D spatial distribution of magnetic fields in the interstellar medium and the intracluster medium is crucial yet challenging. The probing of the 3D magnetic field’s 3D distribution, including the field plane-of-sky orientation ( ψ ), the ...

Diagnosing the Particle Transport Mechanism in the Pulsar Halo via X-Ray Observations
The Astrophysical JournalPulsar halos (also termed “TeV halos”) are a new class of γ -ray sources in the Galaxy, which manifest as extended γ -ray emission around middle-aged pulsars, as discovered around the Geminga pulsar, the Monogem pulsar, and PSR J0622+3749 by the High ...

Limits on dark matter annihilation from the shape of radio emission in M31
Journal of High Energy PhysicsWell-motivated models of dark matter often result in a population of electrons and positrons within galaxies produced through dark matter annihilation — usually in association with gamma rays.

Study of Magnetic Field and Turbulence in the TeV Halo around the Monogem Pulsar
The Astrophysical JournalMagnetic fields are ubiquitous in the interstellar medium, including extended objects such as supernova remnants and diffuse halos around pulsars. Its turbulent characteristics govern the diffusion of cosmic rays and the multiwavelength emission from ...

Kiloparsec-scale Alignment of a Radio Jet with Cool Gas and Dust in a z ∼ 6 Quasar
The Astrophysical Journal LettersWe present high-angular-resolution (0 $\mathop{.}\limits^{\unicode{x02033}}$ 068, ∼400 pc) Atacama Large Millimeter/submillimeter Array (ALMA) imaging of the [C ii ] line and dust continuum emission of PSO J352.4034–15.3373, a radio-loud quasar at z = 5 ...

The Astrophysical Journal Supplement SeriesGalactic foreground emission plays a key role in cosmic microwave background (CMB) science, particularly for detecting primordial gravitational waves. A well-known lesson involves the “dust wave” identified by BICEP2 in 2014, which was ruled out through ...

Multiwavelength Afterglows as Diagnostic Probes of Dense Circumburst Medium in GRBs
The Astrophysical JournalGamma-ray bursts (GRBs) are generally believed to occur in environments where the surrounding medium is either a uniform interstellar medium, or in some cases, a dense stellar wind from a massive progenitor.
