XMM-Newton Resolves Parsec-scale X-ray Jets in the PeVatron Microquasar V4641 Sgr
Naomi Tsuji, Caterina Tresoldi, Kaya Mori +34
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of deg…
The average X-ray spectrum of the volume-complete M-, F-, G-, and K-type star sample within 10 pc of the Sun
Xueying Zheng, Gabriele Ponti, Nicola Locatelli +15
F, G, K and M type stars are the most abundant stellar population in the Milky Way and are expected to contribute to its diffuse X-ray emission. Yet their intrinsic average X-ray s…
A magnetised Galactic halo from inner Galaxy outflows
He-Shou Zhang, Gabriele Ponti, Ettore Carretti +12
Magnetic halos of galaxies are crucial for understanding galaxy evolution, galactic-scale outflows, and feedback from star formation activity. Identifying the magnetised halo of th…
Discovery of the Goat Horn complex: a deg diffuse X-ray source connected to radio loop XII
Nicola Locatelli, Gabriele Ponti, Andrea Merloni +7
A dozen of patches of polarized radio emission spanning tens of degrees in the form of coherent and stationary loops are observed at radio frequencies across the sky. Their origin…
Diffuse -ray emission in Cygnus X: Comments to Yan & Pavaskar
Ottavio Fornieri, Heshou Zhang
It has been pointed out in arXiv:2211.17057 that our recent (published) paper might be revised, due to an incorrect evaluation of the diffusion coefficients, , employed in th…
MHD decomposition explains diffuse -ray emission in Cygnus X
Ottavio Fornieri, Heshou Zhang
Cosmic-ray (CR) diffusion is the result of the interaction of such charged particles against magnetic fluctuations. These fluctuations originate from large-scale turbulence cascadi…
Polarization of fluorescence lines: tracing magnetic field from circumstellar medium to early universe
Heshou Zhang, Huirong Yan
Fluorescence emission lines are broadly applied in observation for diffuse medium in the universe. They are normally observed around strong pumping source, tracing the gas in circu…
Cosmic ray Transport in Magnetohydrodynamic turbulence
Snehanshu Maiti, Kirit Makwana, Heshou Zhang +1
This paper studies cosmic ray (CR) transport in magneto hydrodynamic (MHD) turbulence. CR transport is strongly dependent on the properties of the magnetic turbulence. We perform t…
Understanding the multiwavelength observation of Geminga's TeV halo: the role of anisotropic diffusion of particles
Ruo-Yu Liu, Huirong Yan, Heshou Zhang
In this letter we propose that the X-ray and the TeV observations in the vicinity of Geminga can be understood in the framework of anisotropic diffusion of injected electrons/posit…
Discovery of polarizations from ground state absorption lines: tracer of sub-Gauss magnetic field on 89Her
Heshou Zhang, Manuele Gangi, Francesco Leone +2
We report the identification of the polarization of ground state absorption lines from post-AGB 89~Hercules. Two ground state neutral iron lines are found to have counterintuitive…
Identification of plasma modes in Galactic turbulence with synchrotron polarization
Heshou Zhang, Alexey Chepurnov, Huirong Yan +3
Magneto-hydrodynamic (MHD) turbulence is ubiquitous and a fundamental ingredient underlying many astrophysical phenomena. The multiphase nature of interstellar medium and diversity…
The influence of atomic alignment on absorption and emission spectroscopy
Heshou Zhang, Huirong Yan, Philipp Richter
Spectroscopic observations play essential roles in astrophysics. They are crucial for determining physical parameters in the universe, providing information about the chemistry of…
Polarisation of submillimetre lines from interstellar medium
Heshou Zhang, Huirong Yan
Magnetic fields play important roles in many astrophysical processes. However, there is no universal diagnostic for the magnetic fields in the interstellar medium (ISM) and each ma…
The influence of magnetic fields on absorption and emission spectroscopies
Heshou Zhang, Huirong Yan, Philipp Richter
Spectroscopic observations play a fundamental role in astrophysics. They are crutial to determine important physical parameters, provide information about the composition of variou…

Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We introduce the LAMOST Stellar Parameter Pipeline at Peking University --- LSP3, developed and implemented for the determinations of radial velocity and stellar atmosp…
Relative Flux Calibration of the LAMOST Spectroscopic Survey of the Galactic Anti-center
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We have developed and implemented an iterative algorithm of flux calibration for the LAMOST Spectroscopic Survey of the Galactic anti-center (LSS-GAC). For a given LSS-GAC plate, t…
Tracing Magnetic Fields by Atomic Alignment in Extended Radiation Fields
Heshou Zhang, Huirong Yan, Le Dong
Tracing magnetic fields is crucial as magnetic fields play an important role in many astrophysical processes. Earlier studies have demonstrated that Ground State Alignment (GSA) is…
A three dimensional extinction map of the Galactic Anticentre from multi-band photometry
B. -Q Chen, X. -W. Liu, H. -B. Yuan +8
We present a three dimensional extinction map in band. The map has a spatial angular resolution, depending on latitude, between 3 -- 9\,arcmin and covers the entire XSTPS-GAC s…
