Cross-spectral Analysis of the Type-C Quasi-periodic Oscillation Shoulder Component in GX 339-4

Haifan Zhu, Mariano Méndez, Pengcheng Yang +8

We revisit Rossi X-ray Timing Explorer (RXTE) observations of GX~3394 during the rising phase of its 2006/2007 outburst and apply a joint power-density-spectrum (PDS)--cross-spe…

Discovery of a quasi-periodic oscillation non-harmonically related to the Type-C QPO in the hard intermedidate state of MAXI J1820+070

Pei Jin, Mariano Méndez, Federico García +2

We present a detailed timing analysis of the transition from the hard-intermediate state (HIMS) to the soft-intermediate state (SIMS) in MAXI J1820+070 using NICER observations. Th…
