Discovery of a second eclipsing, bursting neutron-star low-mass X-ray binary in the globular cluster Terzan 6
Maureen van den Berg, Jeroen Homan, Craig O. Heinke +4
We have analyzed Chandra and Suzaku observations of the globular cluster Terzan 6, made when the recurrent transient GRS 1747-312 was in quiescence. Our analysis reveals the presen…
Discovery and Rapid Follow-up Observations of the Unusual Type II SN 2018ivc in NGC 1068
K. A. Bostroem, S. Valenti, D. J. Sand +44
We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual Type II supernova that exploded in NGC 1068 (D=10.1 Mpc). The light curve of SN 2018ivc d…
Continued Neutron Star Crust Cooling of the 11 Hz X-Ray Pulsar in Terzan 5: A Challenge to Heating and Cooling Models?
N. Degenaar, R. Wijnands, E. F. Brown +8
The transient neutron star low-mass X-ray binary and 11 Hz X-ray pulsar IGR J17480-2446 in the globular cluster Terzan 5 exhibited an 11-week accretion outburst in 2010. Chandra ob…
Typing Supernova Remnants Using X-ray Line Emission Morphologies
Laura A. Lopez, Enrico Ramirez-Ruiz, Carles Badenes +3
We present a new observational method to type the explosions of young supernova remnants (SNRs). By measuring the morphology of the Chandra X-ray line emission in seventeen Galacti…
