Geometry of the comptonization region of MAXI J1348$-$630 through type-C quasi-periodic oscillations with NICER

Kevin Alabarta, Mariano Méndez, Federico García +5

We use the rms and lag spectra of the type-C quasi-periodic oscillation (QPO) to study the properties of the Comptonisation region (aka corona) during the low/hard and hard-interme…
