Measurements of the diffuse Galactic synchrotron spectral index and curvature from MeerKLASS pilot data

Melis O. Irfan, Philip Bull, Mario G. Santos +6

21cm intensity mapping experiments are bringing an influx of high spectral resolution observational data in the $\sim 100$ MHz $-1$ GHz regime. We use pilot $971-1075$ MHz data fro…
