Optical follow-up of the neutron star-black hole mergers S200105ae and S200115j
Shreya Anand, Michael W. Coughlin, Mansi M. Kasliwal +46
LIGO and Virgo's third observing run (O3) revealed the first neutron star-black hole (NSBH) merger candidates in gravitational waves. These events are predicted to synthesize r-pro…
The Chandra Deep Wide-Field Survey: A New Chandra Legacy Survey in the Boötes Field I. X-ray Point Source Catalog, Number Counts and Multi-Wavelength Counterparts
A. Masini, R. C. Hickox, C. M. Carroll +30
We present a new, ambitious survey performed with the Chandra X-ray Observatory of the 9.3 deg Boötes field of the NOAO Deep Wide-Field Survey. The wide field probes a statisti…
Multiwavelength Radio Observations of Two Repeating Fast Radio Burst Sources: FRB 121102 and FRB 180916.J0158+65
Aaron B. Pearlman, Walid A. Majid, Thomas A. Prince +4
The spectra of fast radio bursts (FRBs) encode valuable information about the source's local environment, underlying emission mechanism(s), and the intervening media along the line…
