NICER observation list: Target ID 463501

We propose to observe one bright and isolated ULX in the galaxy NGC 1042, simultaneously with broadband coverage by NICER and NuSTAR for the first time. Motivated by a marginal detection of pulsation in one archival XMM data with poor statistics, we want to confirm the pulsation with new NICER data. Our primary aim is to detect the pulsation of ULX1 central compact object with high confidence and study the spectral properties of the source in broad energy band. The detailed spectral study of this ULX will quantify both the soft and hard spectral components which was not possible previously because of unavailability of high S/N ratio data with broadband coverage. Therefore, we propose to obtain simultaneous observations with 50 ks of NICER and 100 ks of NuSTAR exposure for NGC 1042 ULX1.
