CHIME/FRB Detection of Eight New Repeating Fast Radio Burst Sources

FRB Collaboration, B. C. Andersen, K. Bandura +54

We report on the discovery of eight repeating fast radio burst (FRB) sources found using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources span a…

A unified binary neutron star merger magnetar model for the Chandra X-ray transients CDF-S XT1 and XT2

Hui Sun, Ye Li, Binbin Zhang +4

Two bright X-ray transients were reported from the Chandra Deep Field South archival data, namely CDF-S XT1 and XT2. Whereas the nature of the former is not identified, the latter…

X-ray spectral and eclipsing model of the clumpy obscurer in active galactic nuclei

Johannes Buchner, Murray Brightman, Kirpal Nandra +2

We present a unification model for a clumpy obscurer in active galactic nuclei (AGN) and investigate the properties of the resulting X-ray spectrum. Our model is constructed to rep…

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…

A magnetar-powered X-ray transient as the aftermath of a binary neutron-star merger

Y. Q. Xue, X. C. Zheng, Y. Li +14

Neutron star-neutron star mergers are known to be associated with short gamma-ray bursts. If the neutron star equation of state is sufficiently stiff, at least some of such mergers…

The First NuSTAR Observation of 4U 1538-522: Updated Orbital Ephemeris and A Strengthened Case for an Evolving Cyclotron Line Energy

Paul B. Hemphill, Richard E. Rothschild, Diana M. Cheatham +7

We have performed a comprehensive spectral and timing analysis of the first NuSTAR observation of the high-mass X-ray binary 4U 1538-522. The observation covers the X-ray eclipse o…

A Second Source of Repeating Fast Radio Bursts

FRB Collaboration, M. Amiri, K. Bandura +57

The discovery of a repeating Fast Radio Burst (FRB) source, FRB 121102, eliminated models involving cataclysmic events for this source. No other repeating FRB has yet been detected…

Observations of Fast Radio Bursts at Frequencies down to 400 Megahertz

FRB Collaboration, Mandana Amiri, Kevin Bandura +52

Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio flashes likely arriving from far outside the Milky Way galaxy. This phenomenon was discovered at radio freq…
