Colloquium
A new era of Fast X-ray Transients
Dr. Jonathan Alexander Quirola Vásquez
Abstract
| Extragalactic Fast X-ray Transients (FXTs) are short X-ray flashes lasting minutes to hours, with poorly understood origins that may include supernova shock breakouts, tidal disruption events, and compact-object mergers. While some FXTs were later identified in archival Chandra and XMM-Newton data years after detection, the Einstein Probe enables rapid discovery and near real-time multiwavelength follow-up. This talk presents key results on FXT energetics, host galaxies, and progenitors from both historical and recent Einstein Probe observations. |

About the speaker
Jonathan Alexander Quirola Vásquez is an astronomer currently working as a postdoc at Radboud University (Netherlands), having earned his Master and PhD from Pontificia Universidad Católica de Chile in 2018 and 2023, respectively. His research focuses on extragalactic fast X-ray transients, with extensive work tied to the Einstein Probe, and Chandra missions. He has secured substantial observing time across major facilities (XMM-Newton, JWST, VLT, GEMINI, GTC) as PI and co-PI, and serves as a referee and member of collaborations including LSST, Euclid, and EP.
