MAXI J1621-501: The First Source Identified by the Swift XRT Deep Galactic Plane Survey Collaboration
Abstract
The transient source MAXI J1621-501 was discovered in October 2017 with the Japanese instrument MAXI on the International Space Station. The source is located within one of the fields of our Swift XRT Deep Galactic Plane Survey, which we had observed prior to the source activation, allowing us to derive a flux upper limit. We subsequently joined forces with the MAXI-ISS team and followed the source evolution for 520 days. During this interval, we triggered our ToO observations with Chandra and we also observed the source with ATCA, Gemini, NuSTAR, NICER and INTEGRAL. These combined data sets led to the identification of the source nature as a Type I X-ray burster in a Low-Mass X-ray Binary. We will discuss our results of the spectral and timing analysis of the source persistent emission and of the numerous Type-I bursts detected with multiple instruments. We will also discuss the long-term light curve of the source, which exhibits additional bursting episodes during the decay phase of the overall outburst.
