Two years of non-thermal emission from the binary neutron star merger GW170817: rapid fading of the jet afterglow and first constraints on the kilonova fastest ejecta
A. Hajela, R. Margutti, K. D. Alexander +27
We present Chandra and VLA observations of GW170817 at ~521-743 days post merger, and a homogeneous analysis of the entire Chandra data set. We find that the late-time non-thermal…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
Observational Constraints on Late-Time Radio Rebrightening of GRB-Supernovae
Charee Peters, Alexander J. van der Horst, Laura Chomiuk +6
We present a search for late-time rebrightening of radio emission from three supernovae (SNe) with associated gamma-ray bursts (GRBs). It has been previously proposed that the unus…
Observable Features of GW170817 Kilonova Afterglow
Adithan Kathirgamaraju, Dimitrios Giannios, Paz Beniamini
The neutron star merger, GW170817, was followed by an optical-infrared transient (a kilonova) which indicated that a substantial ejection of mass at trans-relativistic velocities o…
EM counterparts of structured jets from 3D GRMHD simulations
Adithan Kathirgamaraju, Alexander Tchekhovskoy, Dimitrios Giannios +1
GW170817/GRB170817A has offered unprecedented insight into binary neutron star post-merger systems. Its Prompt and afterglow emission imply the presence of a tightly collimated rel…
Prediction of the second peak in the afterglow of GW170817
Maxim V. Barkov, Adithan Kathirgamaraju, Yonggang Luo +2
We performed calculations of the late radio and X-ray afterglow of GRB/GW170817 in the cocoon-jet paradigm, predicting the appearance of a second peak in the afterglow light curve…
