Therefore, it is necessary and interesting to determine the central BH mass in {\\it Swift} J2058.4+0516 by one another independent method. Here, based on the theoretical TDE model applied to describe the long-term time-dependent X-ray variabilities of {\\it Swift} J2058.4+0516, the central BH mass can be well determined to be around $1.05_{-0.29}^{+0.39}\\times10^5{\\rm M_\\odot}$, after kind considerations of suggested intrinsic beaming effects from such relativistic jet tightly related to TDE. Moreover, the {\\it Swift} J2058.4+0516 is an unique object in the space of BH masses versus energy transfer efficiencies of the reported TDE candidates, providing interesting clues to detect and/or anticipate candidates of relativistic TDE to make the birth of relativistic jets.", "revisions": [ { "version": "v1", "updated": "2022-02-23T01:46:24.000Z" } ], "analyses": { "keywords": [ "distant tidal disruption event candidate", "central black hole mass", "bh mass", "relativistic jet" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable" } } }
