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…
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…
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…
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 LAMOST Stellar Parameter Pipeline at Peking University --- LSP3
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…
