Description
On behalf of the MMGPS team, I will present preliminary results from the ongoing 3000-h MPIfR MeerKAT Galactic Plane Survey being performed at L and S bands. The survey provides high-fidelity maps at ∼ 20μJy/beam with 5-20′′ resolution. Due to the dense array configuration of MeerKAT and sensitivity towards low surface brightness diffuse emission, we detect a plethora of extended structures. When completed, the survey will produce an unprecedented rotation measure (RM) grid that will be sensitive to |RM| up to 2 × 10^4 rad/m2 with an accuracy of ∼ 15 rad/m2, and Faraday depth structures extended up to 280 rad/m2. The data products from the MMGPS, comprising of maps of total intensity, spectral index, polarized intensity, and Faraday depth, will provide a detailed view of the thermal and nonthermal emission processes of the extended diffuse emission, filamentary structures and the 3D magnetic field structures in the turbulent Galactic plane. This will enable us to investigate a diverse array of astrophysical phenomena, encompassing supernova remnants, molecular gas, HII regions, star-forming complexes and non-thermal filaments.
