Probing a Magnetar Origin for the population of Extragalactic Fast X-ray Transients detected by Chandra

J. Quirola-Vásquez, F. E. Bauer, P. G. Jonker +10

Twenty-two extragalactic fast X-ray transients (FXTs) have now been discovered from two decades of Chandra data (analyzing ~259 Ms of data), with 17 associated with distant galaxie…

Extragalactic FXT Candidates Discovered by Chandra (2014-2022)

J. Quirola-Vásquez, F. E. Bauer, P. G. Jonker +9

Extragalactic fast X-ray transients (FXTs) are short flashes of X-ray photons of unknown origin that last a few minutes to hours. We extend the search for extragalactic FXTs from Q…

Extragalactic fast X-ray transient candidates discovered by Chandra (2000-2014)

J. Quirola-Vasquez, F. E. Bauer, P. G. Jonker +7

Extragalactic Fast X-ray Transients (FXRTs) are short flashes of X-ray photons spanning a few seconds to hours, with an uncertain origin. Our ignorance about their physical mechani…

Searching for fast extragalactic X-ray transients in Chandra surveys

Guang Yang, W. N. Brandt, S. F. Zhu +4

Recent works have discovered two fast ( ks) extragalactic X-ray transients in the Chandra Deep Field-South (CDF-S XT1 and XT2). These findings suggest that a large popu…

Long-Term X-ray Variability of Typical Active Galactic Nuclei in the Distant Universe

G. Yang, W. Brandt, B. Luo +13

We perform long-term ( yr, observed-frame) X-ray variability analyses of the 68 brightest radio-quiet active galactic nuclei (AGNs) in the 6 Ms Deep Field-Sou…
