The Search for a Counterpart to NuSTAR J053449+2126.0
Antonio C. Rodriguez, Yuhan Yao, Kishalay De, S.R. Kulkarni
TL;DR
This paper investigates the nature of an X-ray source, NuSTAR J053449+2126.0, by analyzing archival optical and infrared data, but finds no clear counterpart, highlighting the need for further follow-up observations.
Contribution
The study systematically searches for optical and infrared counterparts to the X-ray source using multiple archival datasets, providing constraints on its possible nature.
Findings
No obvious optical or infrared counterpart identified.
Archival data do not conclusively determine the source's nature.
Further X-ray and optical follow-up required.
Abstract
Tumer et al. 2022, ATel #15171, have recently reported the discovery of an X-ray source, NuSTAR J053449+2126.0, during a calibration observation which took place on 25 April 2020. We scan the Zwicky Transient Facility (ZTF) alerts and archival photometry to determine the nature of the source. Palomar Gattini-IR is searched as well. We identify no obvious counterpart candidate. Follow-up X-ray and optical studies are needed to determine the true counterpart.
