Target of Opportunity Observations of Gravitational Wave Events with Vera C. Rubin Observatory
Igor Andreoni, Raffaella Margutti, Om Sharan Salafia +52
The discovery of the electromagnetic counterpart to the binary neutron star merger GW170817 has opened the era of gravitational-wave multi-messenger astronomy. Rapid identification…
Radio and X-ray observations of the luminous Fast Blue Optical Transient AT2020xnd
Joe S. Bright, Raffaella Margutti, David Matthews +25
We present deep X-ray and radio observations of the Fast Blue Optical Transient (FBOT) AT2020xnd/ZTF20acigmel at from d to d after explosion. AT2020xnd belongs…
Extragalactic Millimeter Transients in the Era of Next Generation CMB Surveys
T. Eftekhari, E. Berger, B. D. Metzger +7
The next generation of wide-field cosmic microwave background (CMB) surveys are uniquely poised to open a new window for time-domain astronomy in the millimeter band. Here we explo…
GRB host galaxies with strong H absorption: CO-dark molecular gas at the peak of cosmic star formation
K. E. Heintz, G. Björnsson, M. Neeleman +13
We present a pilot search of CO emission in three H-absorbing, long-duration gamma-ray burst (GRB) host galaxies at z~2-3. We used the Atacama Large Millimeter/sub-millimeter A…
Evidence for X-ray Emission in Excess to the Jet Afterglow Decay 3.5 yrs After the Binary Neutron Star Merger GW 170817: A New Emission Component
A. Hajela, R. Margutti, J. S. Bright +34
For the first years after the binary neutron star merger event GW 170817 the radio and X-ray radiation has been dominated by emission from a structured relativistic off-axi…
A Late-Time Galaxy-Targeted Search for the Radio Counterpart of GW190814
K. D. Alexander, G. Schroeder, K. Paterson +14
GW190814 was a compact object binary coalescence detected in gravitational waves by Advanced LIGO and Advanced Virgo that garnered exceptional community interest due to its excelle…
