A spectro-temporal view of normal branch oscillations in Cygnus X-2 as seen by NICER and NuSTAR
Malu Sudha, Renee M. Ludlam, Diego Altamirano +2
We report the spectro-temporal study of the neutron star low mass X-ray binary Cygnus X-2 using NICER and NuSTAR data while the source was in the normal branch (NB). We detect a no…

Investigating the Ultra-Compact X-ray Binary Candidate SLX 1735-269 with NICER and NuSTAR
David Moutard, Renee Ludlam, Malu Sudha +8
We present two simultaneous NICER and NuSTAR observations of the ultra-compact X-ray binary (UCXB) candidate SLX 1735-269 while the source was in two different spectral states. Usi…
